Analysis 

The private pilot was departing on a cross-country flight in the airplane when the forward baggage compartment door opened shortly before the airplane rotated for liftoff near midfield. The pilot continued the takeoff on runway heading to about 100 ft above ground level before entering a left turn. The airplane continued to turn left until it was on a downwind heading, and then it entered an aerodynamic stall/spin and descended nose-down into terrain. Flight track data revealed that the airplane's ground speed decreased from 84 knots to 1 knot during the final 4 seconds of the flight, consistent with the airplane entering an aerodynamic stall/spin. None of the witnesses reported hearing any engine anomalies during the accident flight.

The postaccident investigation determined that the forward baggage compartment door separated during the airplane's impact with terrain. The door latch mechanism was found unlatched, and its corresponding key-lock assembly was unlocked. No anomalies were found with the forward baggage door latch mechanism, key-lock, or door frame latch catch/receptacle that would have precluded the door from being properly secured before the flight. Based on the witness descriptions and the physical evidence, it is likely that the pilot failed to ensure that the forward baggage compartment door was closed, latched, and properly secured during his preflight inspection. The pilot likely became distracted by the open baggage door and, as a result, did not maintain adequate airspeed while on the downwind leg, which resulted in the airplane exceeding its critical angle of attack and experiencing an aerodynamic stall at a low altitude. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain adequate airspeed after becoming distracted by the open baggage door while operating in the airport traffic pattern, which resulted in the airplane exceeding its critical angle of attack and experiencing an aerodynamic stall at a low altitude. Contributing to the accident was the pilot's failure to ensure that the forward baggage compartment door was closed, latched, and properly secured during his preflight inspection.

On July 8, 2016, about 1617 central daylight time, a Piper PA-32R-300 single-engine airplane, N32KK, impacted terrain following a loss of control in the airport traffic pattern shortly after takeoff from the West Houston Airport (IWS), Houston, Texas. The private pilot and three passengers were fatally injured, and the airplane was destroyed. The airplane was registered to and operated by the pilot under the provisions of Title 14 Code of Federal Regulations (CFR) Part 91 without a flight plan. Day visual meteorological conditions prevailed for the personal cross-country flight that had an intended destination of Gillespie County Airport (T82), Fredericksburg, Texas.

Numerous witnesses observed the airplane during its takeoff from runway 15. Several of the witnesses saw the forward baggage compartment door in a fully open, vertical orientation shortly before the airplane rotated for liftoff. The pilot continued with the takeoff, and the airplane climbed on runway heading to 100 to 150 ft above ground level before it entered a left turn to the crosswind leg. One witness estimated that the left turn began as the airplane crossed over the runway departure threshold. Several witnesses reported that the airplane maintained a bank angle of 30° to 45° during the left turn to the crosswind leg. The airplane continued turning left to the downwind leg and briefly rolled to a wings-level attitude before it entered an aerodynamic stall/spin to the left and descended nose-down into terrain. None of the witnesses reported hearing any engine anomalies during the flight.

The pilot's Apple iPad 4, which was recovered at the accident site, was configured with the ForeFlight application and recorded a tracklog for the flight. The tracklog began about 1613:22 with the airplane on the taxiway. The airplane held short of runway 15 until about 1615:51. About 1616:04, the airplane began its takeoff roll on runway 15. At 1616:27, the airplane became airborne with about 1/2 of the available runway remaining. At 1616:31, at a groundspeed of 74 knots and GPS altitude of 128 ft, the airplane began to deviate left of the runway 15 centerline. The airplane's path followed a left arc with the highest recorded GPS altitude of 179 ft recorded at 1616:53. At 1616:59, the airplane was established on a 349° true heading at a GPS altitude of 139 ft and a recorded groundspeed of 84 knots. Four seconds later, at 1617:03, the airplane had descended to a GPS altitude of 121 ft and decelerated to 1 knot ground speed.

The accident site was in a wooded residential area about 1/2 mile east-northeast of the airport terminal building/ramp. The initial point-of-impact was identified as a 60-ft-tall pine tree that was fractured about 6.5 ft above the ground. A 100 ft wreckage debris path initiated from the pine tree on a 330° true heading. There were numerous broken pine tree branches located along the wreckage debris path. The main wreckage was found upright on a 180° heading and about 42 ft from the initial point-of-impact. The main wreckage consisted of the fuselage (aft of the cockpit), both wings, and the empennage. A majority of the main wreckage had been destroyed by postimpact fire. Flight control cable continuity could not be established due to impact and fire damage; however, all observed separations were consistent with overstress. The mechanical flap control lever was found in the fully retracted position. All three landing gear actuators were fully extended, consistent with an extended landing gear. The fuel selector was found positioned to the right fuel tank.

The cockpit, forward baggage compartment, engine, and propeller were located about 58 ft past the main wreckage. The cockpit instrument panel was destroyed by fire. The landing gear selector switch was found in the DOWN position. The ignition key-switch was found in the BOTH position. The forward baggage compartment exhibited impact and fire damage. The forward baggage compartment door was found about 15 ft from the baggage compartment. The door latch mechanism was observed unlatched, and its corresponding key-lock assembly was unlocked. A functional test of the latch mechanism did not reveal any anomalies. The forward baggage door frame latch catch/receptacle also appeared to be undamaged. There were no observed anomalies with the forward baggage door latch mechanism, key-lock, or the door frame latch catch/receptacle.

The engine remained attached to the firewall, and the propeller remained attached to the crankshaft flange. The two-blade propeller exhibited torsional twisting, trailing edge S-shaped bending, and burnishing of the blade faces and backs. Internal engine and valve train continuity were confirmed as the engine crankshaft was rotated. Compression and suction were noted on all cylinders in conjunction with crankshaft rotation. The single-drive dual-magneto did not provide a spark when rotated; however, the magneto exhibited damage consistent with prolonged exposure to fire. A boroscope inspection did not reveal any anomalies with the cylinders, pistons, valves, or valve seats. The upper spark plugs were removed and exhibited features consistent with normal engine operation. The fuel injection servo remained attached to the engine. There were no obstructions to the fuel injection servo or induction system. The servo fuel inlet screen was free of contamination. No anomalies were observed with the mechanical fuel pump, fuel flow divider, or fuel injectors. The oil pump discharged oil in conjunction with crankshaft rotation. The oil suction screen was free of contamination. The postaccident examination revealed no evidence of a mechanical malfunction or failure that would have precluded normal engine operation. 



Medical And Pathological Information

The Harris County Institute of Forensic Sciences, Houston, Texas, performed an autopsy on the pilot. The cause of death was attributed to multiple blunt-force and thermal injuries sustained during the accident.

The FAA's Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma, performed toxicology tests on specimens obtained during the autopsy. The pilot's toxicology results were negative for carbon monoxide and ethanol. Cetirizine was detected in urine, but not in blood. The absence of the substance in blood is considered non-impairing. Cetirizine is a potentially-sedating antihistamine available over the counter with a variety of names, including Zyrtec. 

Tests And Research

The airplane was equipped with an Electronics International UBG-16 engine monitor and FP-5L fuel computer. The UBG-16 engine monitor displays exhaust gas temperature, cylinder head temperature, and other engine parameters. The FP-5L fuel computer displays instantaneous fuel flow and total fuel usage/remaining information. The UBG-16 and FP-5L were recovered at the accident site and sent to the NTSB Vehicle Recorder Laboratory for examination. Both devices exhibited significant thermal damage that precluded any non-volatile data recovery.

The airplane was also equipped with Electronics International MUX-8A data recorder, which was configured to record various engine data parameters. The device was recovered at the accident site and sent to the NTSB Vehicle Recorder Laboratory for examination. A download of the device revealed no data associated with the accident flight; the last time the device recorded engine data was on June 5, 2015. 

Additional Information

The airplane, a 1976 model-year, serial number 32R-7680117, was not equipped with a forward baggage compartment door annunciator. According to the airframe manufacturer, Piper PA-32 series airplanes, beginning with the 1983 model-year, with serial numbers 32-8306001 and higher, were equipped from the factory with a forward baggage compartment door annunciator to alert the pilot of an unsecured baggage door.

This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

On July 8, 2016, about 1615 central daylight time, a Piper model PA-32R-300 single-engine airplane, N32KK, was destroyed during a postimpact fire following a loss of control shortly after takeoff from the West Houston Airport (IWS), Houston, Texas. The private pilot and his three passengers were fatally injured. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 without a flight plan. Day visual meteorological conditions (VMC) prevailed for the personal cross-country flight that had an intended destination of Gillespie County Airport (T82), Fredericksburg, Texas.

There were numerous witnesses who reported observing the accident airplane while on takeoff from runway 15 (3,953 feet by 75 feet, asphalt). Several of the witnesses observed an open forward baggage compartment door shortly before the airplane rotated for liftoff. These witnesses reported that the forward baggage compartment door was in a vertical position. The airplane continued with the takeoff and climbed on runway heading to 100-150 feet above ground level (agl) before it entered a left crosswind turn. One witness estimated that the left crosswind turn began as the airplane crossed over the runway departure threshold. Several witnesses reported that the airplane maintained a bank angle of 30-45 degrees during the left crosswind turn. The airplane was observed to briefly roll into a wings level attitude, on a downwind heading, before it entered an aerodynamic stall/spin to the left and descended nose first into terrain. The witnesses did not report hearing any engine anomalies during the accident flight.

The accident site was located in a wooded residential area located about 1/2 mile east-northeast of the airport terminal building/ramp. The initial point-of-impact was identified as an approximately 60-foot tall pine tree that was fractured about 6-1/2 feet above the ground. A 100 foot wreckage debris path initiated from the pine tree on a 330-degree true heading. There were numerous broken pine tree branches located along the wreckage debris path. The main wreckage was located about 42 feet from the initial point-of-impact and was found upright on a 180-degree heading. The main wreckage consisted of the fuselage (aft of the cockpit), both wings, and the empennage. A majority of the main wreckage had been destroyed by the postimpact fire. Flight control continuity could not be established due to impact and fire damage; however, all observed separations were consistent with overstress. The mechanical flap control lever was found in the fully retracted position. All three landing gear actuators were fully extended, consistent with an extended landing gear. The fuel selector was found positioned to the right fuel tank. The cockpit, forward baggage compartment, engine, and the propeller were located about 58 feet past the main wreckage. The cockpit instrument panel was destroyed by fire. The landing gear selector switch was found in the "gear-down" position. The ignition switch was found in the "both" position. The forward baggage compartment exhibited impact and fire damage. The forward baggage compartment door was found about 15 feet from the baggage compartment. The door latch mechanism was observed unlatched and its corresponding key-lock assembly unlocked. A functional test of the latch mechanism did not reveal any anomalies. The forward baggage door frame latch catch/receptacle appeared to be undamaged. There were no observed anomalies with the forward baggage door latch mechanism, key-lock, or the door frame latch catch/receptacle.

The engine remained attached to the firewall and the propeller remained attached to the crankshaft flange. The two-blade propeller exhibited torsional twisting, trailing edge S-shaped bending, and burnishing of the blade face and back. Internal engine and valve train continuity was confirmed as the engine crankshaft was rotated. Compression and suction were noted on all cylinders in conjunction with crankshaft rotation. The single-drive dual-magneto did not provide a spark when rotated; however, the magneto was damaged consistent with prolonged exposure to fire. The upper spark plugs were removed and exhibited features consistent with normal engine operation. A borescope inspection of each cylinder did not reveal any anomalies. The fuel injection servo remained attached to the engine. There were no obstructions to the fuel injection servo or induction system. The servo fuel inlet screen was free of any contamination. No anomalies were observed with the mechanical fuel pump, fuel flow divider, or fuel injectors. The oil pump discharged oil in conjunction with crankshaft rotation.

The accident site was in a wooded residential area about 1/2 mile east-northeast of the airport terminal building/ramp. The initial point-of-impact was identified as a 60-ft-tall pine tree that was fractured about 6.5 ft above the ground. A 100 ft wreckage debris path initiated from the pine tree on a 330° true heading. There were numerous broken pine tree branches located along the wreckage debris path. The main wreckage was found upright on a 180° heading and about 42 ft from the initial point-of-impact. The main wreckage consisted of the fuselage (aft of the cockpit), both wings, and the empennage. A majority of the main wreckage had been destroyed by postimpact fire. Flight control cable continuity could not be established due to impact and fire damage; however, all observed separations were consistent with overstress. The mechanical flap control lever was found in the fully retracted position. All three landing gear actuators were fully extended, consistent with an extended landing gear. The fuel selector was found positioned to the right fuel tank.

The cockpit, forward baggage compartment, engine, and propeller were located about 58 ft past the main wreckage. The cockpit instrument panel was destroyed by fire. The landing gear selector switch was found in the DOWN position. The ignition key-switch was found in the BOTH position. The forward baggage compartment exhibited impact and fire damage. The forward baggage compartment door was found about 15 ft from the baggage compartment. The door latch mechanism was observed unlatched, and its corresponding key-lock assembly was unlocked. A functional test of the latch mechanism did not reveal any anomalies. The forward baggage door frame latch catch/receptacle also appeared to be undamaged. There were no observed anomalies with the forward baggage door latch mechanism, key-lock, or the door frame latch catch/receptacle.

The engine remained attached to the firewall, and the propeller remained attached to the crankshaft flange. The two-blade propeller exhibited torsional twisting, trailing edge S-shaped bending, and burnishing of the blade faces and backs. Internal engine and valve train continuity were confirmed as the engine crankshaft was rotated. Compression and suction were noted on all cylinders in conjunction with crankshaft rotation. The single-drive dual-magneto did not provide a spark when rotated; however, the magneto exhibited damage consistent with prolonged exposure to fire. A boroscope inspection did not reveal any anomalies with the cylinders, pistons, valves, or valve seats. The upper spark plugs were removed and exhibited features consistent with normal engine operation. The fuel injection servo remained attached to the engine. There were no obstructions to the fuel injection servo or induction system. The servo fuel inlet screen was free of contamination. No anomalies were observed with the mechanical fuel pump, fuel flow divider, or fuel injectors. The oil pump discharged oil in conjunction with crankshaft rotation. The oil suction screen was free of contamination. The postaccident examination revealed no evidence of a mechanical malfunction or failure that would have precluded normal engine operation. 

Medical And Pathological Information

The Harris County Institute of Forensic Sciences, Houston, Texas, performed an autopsy on the pilot. The cause of death was attributed to multiple blunt-force and thermal injuries sustained during the accident.

The FAA's Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma, performed toxicology tests on specimens obtained during the autopsy. The pilot's toxicology results were negative for carbon monoxide and ethanol. Cetirizine was detected in urine, but not in blood. The absence of the substance in blood is considered non-impairing. Cetirizine is a potentially-sedating antihistamine available over the counter with a variety of names, including Zyrtec. 

Tests And Research

The airplane was equipped with an Electronics International UBG-16 engine monitor and FP-5L fuel computer. The UBG-16 engine monitor displays exhaust gas temperature, cylinder head temperature, and other engine parameters. The FP-5L fuel computer displays instantaneous fuel flow and total fuel usage/remaining information. The UBG-16 and FP-5L were recovered at the accident site and sent to the NTSB Vehicle Recorder Laboratory for examination. Both devices exhibited significant thermal damage that precluded any non-volatile data recovery.

The airplane was also equipped with Electronics International MUX-8A data recorder, which was configured to record various engine data parameters. The device was recovered at the accident site and sent to the NTSB Vehicle Recorder Laboratory for examination. A download of the device revealed no data associated with the accident flight; the last time the device recorded engine data was on June 5, 2015. 

Additional Information

The airplane, a 1976 model-year, serial number 32R-7680117, was not equipped with a forward baggage compartment door annunciator. According to the airframe manufacturer, Piper PA-32 series airplanes, beginning with the 1983 model-year, with serial numbers 32-8306001 and higher, were equipped from the factory with a forward baggage compartment door annunciator to alert the pilot of an unsecured baggage door.

On July 8, 2016, about 1615 central daylight time, a Piper model PA-32R-300 single-engine airplane, N32KK, was destroyed during a postimpact fire following a loss of control shortly after takeoff from the West Houston Airport (IWS), Houston, Texas. The private pilot and his three passengers were fatally injured. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 without a flight plan. Day visual meteorological conditions (VMC) prevailed for the personal cross-country flight that had an intended destination of Gillespie County Airport (T82), Fredericksburg, Texas.

There were numerous witnesses who reported observing the accident airplane while on takeoff from runway 15 (3,953 feet by 75 feet, asphalt). Several of the witnesses observed an open forward baggage compartment door shortly before the airplane rotated for liftoff. These witnesses reported that the forward baggage compartment door was in a vertical position. The airplane continued with the takeoff and climbed on runway heading to 100-150 feet above ground level (agl) before it entered a left crosswind turn. One witness estimated that the left crosswind turn began as the airplane crossed over the runway departure threshold. Several witnesses reported that the airplane maintained a bank angle of 30-45 degrees during the left crosswind turn. The airplane was observed to briefly roll into a wings level attitude, on a downwind heading, before it entered an aerodynamic stall/spin to the left and descended nose first into terrain. The witnesses did not report hearing any engine anomalies during the accident flight.

The accident site was located in a wooded residential area located about 1/2 mile east-northeast of the airport terminal building/ramp. The initial point-of-impact was identified as an approximately 60-foot tall pine tree that was fractured about 6-1/2 feet above the ground. A 100 foot wreckage debris path initiated from the pine tree on a 330-degree true heading. There were numerous broken pine tree branches located along the wreckage debris path. The main wreckage was located about 42 feet from the initial point-of-impact and was found upright on a 180-degree heading. The main wreckage consisted of the fuselage (aft of the cockpit), both wings, and the empennage. A majority of the main wreckage had been destroyed by the postimpact fire. Flight control continuity could not be established due to impact and fire damage; however, all observed separations were consistent with overstress. The mechanical flap control lever was found in the fully retracted position. All three landing gear actuators were fully extended, consistent with an extended landing gear. The fuel selector was found positioned to the right fuel tank. The cockpit, forward baggage compartment, engine, and the propeller were located about 58 feet past the main wreckage. The cockpit instrument panel was destroyed by fire. The landing gear selector switch was found in the "gear-down" position. The ignition switch was found in the "both" position. The forward baggage compartment exhibited impact and fire damage. The forward baggage compartment door was found about 15 feet from the baggage compartment. The door latch mechanism was observed unlatched and its corresponding key-lock assembly unlocked. A functional test of the latch mechanism did not reveal any anomalies. The forward baggage door frame latch catch/receptacle appeared to be undamaged. There were no observed anomalies with the forward baggage door latch mechanism, key-lock, or the door frame latch catch/receptacle.

The engine remained attached to the firewall and the propeller remained attached to the crankshaft flange. The two-blade propeller exhibited torsional twisting, trailing edge S-shaped bending, and burnishing of the blade face and back. Internal engine and valve train continuity was confirmed as the engine crankshaft was rotated. Compression and suction were noted on all cylinders in conjunction with crankshaft rotation. The single-drive dual-magneto did not provide a spark when rotated; however, the magneto was damaged consistent with prolonged exposure to fire. The upper spark plugs were removed and exhibited features consistent with normal engine operation. A borescope inspection of each cylinder did not reveal any anomalies. The fuel injection servo remained attached to the engine. There were no obstructions to the fuel injection servo or induction system. The servo fuel inlet screen was free of any contamination. No anomalies were observed with the mechanical fuel pump, fuel flow divider, or fuel injectors. The oil pump discharged oil in conjunction with crankshaft rotation. The oil suction screen was free of any contamination. The postaccident examination revealed no evidence of preimpact mechanical malfunctions or failures that would have precluded normal engine operation.

HOUSTON - The Harris County Sheriff's Office is investigating a plane crash in west Harris County on Friday. The accident happened just after 4 p.m.

A small plane took off from West Houston Airport at 18000 Groschke Road and crashed in the woods nearby, according to officials. The plane caught fire in the woods a quarter-mile east of the runway. The plane was destroyed by fire after impact.

All four passengers died when the single-engine Piper PA-32 went down, officials said.

Gustavo Trevino recorded cell phone video seconds after the deadly crash.

Trevino works near West Houston Airport and saw the plane go down just after take off.

"The plane was taking off and I knew something was wrong," Trevino said.

He ran to the scene to look for people on board because he wanted to help.

"I tried to go in. I couldn't do anything," Trevino said. "The flames were too intense. Just too intense."

The plane crashed just a few feet from Sherry and George Turner's home.

They hear planes taking off and landing every day, but they knew something was wrong with this one.

"That didn't sound normal. As soon as I got outside, I saw the smoke and the heat signature from the fire," George said.

Investigators say they will use dental records and finger prints to identify them.

They haven't even confirmed the plane's tail number because it's so badly damage.

"The plane is completely destroyed and burned," DPS officer Stephen Woodard said. "Right now this is a terrible time for this community because this is a flight community. A lot of folks in this community own planes and they're pilots as well. So it's a trying time."

It is unclear what caused the plane to crash at this time.

"Right now, everything is being preserved. The aircraft engine and all the instruments are in place waiting for the experts to come in and do the proper investigation," Woodard said.
