NTSB Identification: ERA12FA572
14 CFR Part 91: General Aviation
Accident occurred Saturday, September 22, 2012 in Land O'Lakes, FL
Probable Cause Approval Date: 06/19/2013
Aircraft: CESSNA 172S, registration: N21750
Injuries: 1 Fatal.
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.
The pilot purchased the airplane and he was returning to his home base. The pilot checked in with an approach controller about 52 miles north-northwest of the destination airport; at the time, the airplane was flying under visual flight rules, and night visual meteorological conditions prevailed. The pilot initiated a gradual descent from 7,500 feet mean sea level and an air traffic controller radioed the pilot after he observed the airplane descending below 1,000 feet mean sea level. The pilot never responded to the controller’s radio calls, and the airplane impacted pastureland about 17 miles from the destination airport.
Examination of the wreckage revealed that the airplane collided with trees at a very shallow descent angle. No evidence of a pre-existing mechanical failure or anomaly was observed.
A review of the pilot’s actions during the 9 days prior to the accident revealed that he flew a 5-day international trip as a crewmember for the airline for which he flew as a captain, and then returned to Zurich 3 days before the accident. About 4 hours later, he began a trip as a passenger to Colorado.
On the day before the accident, the pilot began the first of three legs of a cross country flight, with the third leg being the accident flight. He was awake for about 18 hours at the time of the accident, with stops only being taken for food and airplane servicing.
Over the 9-day period before the accident, the pilot made three crossings of the Atlantic Ocean (each exceeding 6 time zones). These multiple and frequent time zone crossings would result in circadian disruption and would have diminished the pilot’s ability to obtain restorative sleep during this period, which, in combination with the pilot’s extended time awake on the day of the accident, would have caused the pilot to be in a fatigued state. The circumstances of the accident and his fatigue-inducing schedule in the preceding days indicate that the pilot most likely fell asleep during the initial descent for landing, and the airplane subsequently descended into the trees and terrain.
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s decision to continue the cross-country flight while fatigued, which resulted in him falling asleep during the initial descent for landing.
HISTORY OF FLIGHT
On September 22, 2012, about 0150 eastern daylight time, a Cessna 172S, N21750, was substantially damaged following a collision with trees and terrain near Land O’Lakes, Florida. The certificated private pilot was fatally injured. The airplane was registered to a corporation and was operated by the pilot as a personal flight under 14 Code of Federal Regulations Part 91. Night, visual meteorological conditions prevailed and no flight plan was filed. The flight originated at Pensacola, Florida (PNS) about 2144 central daylight time on September 21, 2012, and was destined for Tampa Executive Airport (VDF), Tampa, Florida.
According to air traffic control (ATC) information, at 0130, the pilot contacted Tampa Approach Control inbound to VDF, about 52 nautical miles (nm) to the north-northwest, at 7,500 feet. At 0134, the pilot informed Tampa Approach that he had the Tampa weather and Tampa Approach issued a visual flight rules (VFR) descent at pilot’s discretion. At 0149, Tampa Approach personnel noticed that the airplane had descended below 1,000 feet, 15 nm northwest of VDF, and they began to call the pilot on the radio. The pilot did not respond when queried by controllers. The airplane continued in a gradual descent until radar contact was lost. At 0243, a police helicopter that was dispatched to the area and the flight crew located the wreckage. There were no known witnesses to the accident.
PERSONNEL INFORMATION
The pilot held a Federal Aviation Administration private pilot certificate with ratings for airplane single-engine land, multiengine land, and instrument airplane. He reported a total flight experience of 13,480 hours on his latest FAA third class medical application, dated August 22, 2011. The pilot’s personal flight logbook was not recovered. The pilot was also a captain for Edelweiss Air, Zurich, Switzerland and a Swiss citizen. He held an airline transport pilot certificate issued in Switzerland under the Joint Aviation Authority and was type rated in the Airbus A320 and A330.
AIRCRAFT INFORMATION
The airplane was a single engine, high wing, fixed tricycle gear airplane, serial number 172S9641. It was powered by a Lycoming IO-360-L2A engine rated at 180 horsepower.
The aircraft was registered to The Connie III Skyhawk LLC, Tampa, Florida. According to the co-owner, who was interviewed at the accident site, the pilot was flying the airplane from Boulder, Colorado to Tampa after its recent purchase. The aircraft logbooks were reportedly in the airplane and were consumed by the post-crash fire. The co-owner provided electronic copies of pertinent logbook entries to the investigation team.
According to the aircraft maintenance records, the last annual inspection on the airframe and engine was performed on March 5, 2012, at a total aircraft time of 2,937.1 hours.
METEOROLOGICAL INFORMATION
The 0153 surface weather observation for Tampa International Airport (TPA), Tampa, Florida, reported wind calm, visibility 10 miles or better, few clouds at 1,500 feet, scattered clouds at 11,000 feet, scattered clouds at 25,000 feet, temperature 23 degrees C, dew point 21 degrees C, and altimeter setting 29.99 inches of mercury.
Moonrise was at 1308 on September 21 and moonset was at 2357 on the same day. The next moonrise occurred after the accident, at 1406 on September 22.
WRECKAGE AND IMPACT INFORMATION
The accident site was situated on private pasture land located about 17 nm north-northwest of VDF. The main wreckage came to rest, inverted, on a heading of 140 degrees. The cockpit and cabin sections of the airplane were consumed in a post-crash fire. The wreckage path from the initial impact with trees to the final resting place was oriented on a 160-degree heading and was about 400 feet in length. The distance from the first ground impact to the main wreckage was approximately 250 feet.
The left wing was observed separated into two major sections. The left outboard section, from the tip to near the wing strut attachment point, was observed on the right side of the wreckage path, approximately 200 feet from the main wreckage. The outboard 4.5 feet of the aileron remained attached. The inboard 4.5 feet of the aileron was observed lodged in trees. The left wing strut was observed separated from both the wing and the fuselage and was approximately 150 feet from the main wreckage. The inboard section of the left wing was observed burned, approximately 30 feet from the main wreckage. The right outboard section was observed near the initial point of impact with the trees. The outboard 4.5 feet of the aileron remained attached. The inboard 4.5 feet of the aileron was found separated from the wing near the initial point of impact. The right inboard section of the right wing was with the fuselage at the main wreckage location.
The empennage remained attached to the fuselage and was at the main wreckage site. The rudder remained attached to the vertical stabilizer. The inboard section of the left elevator and the entire right elevator remained attached to the horizontal stabilizers. The outboard 2.5 feet of the left elevator was observed separated and was 125 feet beyond the first impact location. The aircraft was equipped with integral wing fuel tanks with a capacity of 56 gallons. The fuel tanks were compromised by impact and post-accident fire. The fuel tank selector handle was destroyed by fire. The fuel valve was in the “both” position. The fuel quantity indicators were damaged in the post impact fire. The fuel strainer was observed attached to the firewall, the bowl was removed and a small amount of residual fuel was observed in the bowl. The fuel screen was observed to be free of debris. The left landing gear strut was observed rotated in the fuselage fitting.
The wing flaps were observed in the retracted (up) position. The wing flap drive mechanism was observed in the retracted position. Control cable continuity was established from the cockpit controls to the rudder and elevators. The left aileron cables exhibited overload separations near wing root. The wing flap cables exhibited overload separations. The right aileron cable exhibited overload separations. The pilot and copilot control wheels were linked together via the cables. All of the cockpit instruments were compromised by the post impact fire and were unreadable. The cabin floorboard and seat tracks were compromised by the post impact fire. All of the seats were observed compromised by the post impact fire.
The engine, as first viewed, remained attached to the firewall and partially attached to the fuselage. The engine sustained post-impact fire and thermal damage. The propeller remained attached to the propeller flange. The primary vacuum pump was dislodged from the accessory housing. All engine components were accounted for at the accident site. With the assistance of wreckage recovery personnel, engine was placed on a flatbed trailer to facilitate an engine examination. The following are the results of the examination.
Both magnetos were secure on their mounts. They were removed and examined; no defects were noted. Both magnetos were rotated by hand and both furnished spark from their outlet points. The fuel injector was secure on its mount. The injector and main fuel line were removed by investigators. An unmeasured amount of fuel was observed draining from the fuel injector. The throttle cable and mixture cable were intact; they were removed to facilitate the fuel injector examination. The throttle plate was observed in the “closed” position. The inlet fuel screen was observed to be free of contaminants. All fuel injector nozzles were removed and examined; they were unobstructed. The fuel flow divider was removed and disassembled; it displayed fire and thermal damage. The diaphragm was consumed by the post-impact fire. No fuel was observed in the fuel flow divider. The engine driven fuel pump was removed and actuated by hand; fuel was expelled when manually operated.
The top spark plugs were removed and they displayed signatures consistent with having been exposed to high thermal temperatures from the post-impact fire and displayed a low service life and a color consistent with normal combustion when compared to a Champion Spark Plug wear chart. The ignition harness was destroyed by post-impact fire.
All rocker covers were removed and the engine was rotated by hand using the propeller. Suction and compression were observed on all cylinders. The accessory gears were observed to be rotating in a normal manner. The rocker arms were observed moving correctly. Crank shaft and camshaft continuity were confirmed. The propeller was secure on the crankshaft flange.
Nothing was observed during the course of the examination that would have precluded the engine from making power prior to initial impact.
MEDICAL AND PATHOLOGICAL INFORMATION
A postmortem examination of the pilot was performed at the Florida District Six Medical Examiner’s Office, Largo, Florida, on September 22, 2012. The autopsy report noted the cause of death as “Blunt Trauma,” with “Thermal Injuries” listed under contributory conditions. The manner of death was “Accident.”
Forensic toxicology testing was performed on specimens of the pilot by the Federal Aviation Administration (FAA) Bioaeronautical Sciences Research Laboratory (CAMI), Oklahoma City, Oklahoma. The CAMI toxicology report indicated no carbon monoxide or cyanide in the blood, no ethanol in vitreous fluid, and no drugs in the urine.

A Cessna 172 crashed in Land O' Lakes early Saturday, and at least one person is dead.
The plane's debris field stretched for about a half-mile.
LAND O'LAKES — The man who died Saturday morning after crashing a small plane was a Swiss citizen and pilot for Edelweiss Air, the Pasco County Sheriff's Office said.
Andreas Wendel, 48, from Bassersdorf, Switzerland, died after crashing the private plane in a field near Lake Irene Drive and Bexley Road.
He had no relatives in the United States, authorities said, but his family in Switzerland has been notified of the death.
The flight originated from Pensacola, but the plane was registered to a man in California, said Pasco sheriff's spokesman Kevin Doll.
At about 3 a.m. Saturday, air traffic control lost track of the plane on radar, and someone on the Suncoast Parkway reported seeing a flash in the woods, Doll said.
Investigators believe Wendel was flying a Cessna 172. The plane's wreckage was spread over an area that is about a quarter to a half mile wide.
The Federal Aviation Administration is still investigating what caused the plane to crash.
LAND O' LAKES -- One man is dead after a small plane crashed in rural Land O' Lakes early today, authorities said.
The 2004 Cessna 172S single-engine aircraft went down in a field not far from Lake Irene Drive and Bexley Road about 3 a.m. It clipped trees on the way down, lost part of its tail in a tree and left a debris field that stretched for about a half-mile.
Although the plane is registered to Stephen Morrissey of Ojai, Calif., it wasn't known whether Morrissey was the pilot. There were no passengers.
According to Pasco County Sheriff's Office spokesman Kevin Doll, the plane was coming from Pensacola. The pilot received clearance to land at Tampa Executive Airport but suddenly dropped off the radar.
No witnesses to the crash have come forward. Air Traffic controllers from Tampa International Airport alerted the FAA to the plane disappearing from radar.
Investigators from the National Transportation Safety Board were headed to the scene.
