Accident Number: WPR18FA104
Date & Time: 03/11/2018, 1257 PDT
Registration: N4511Y
Aircraft: PIPER PA 18-150
Aircraft Damage: Destroyed
Defining Event: Loss of control in flight
Injuries: 1 Fatal
Flight Conducted Under: Part 91: General Aviation - Personal
On March 11, 2018, about 1257 Pacific daylight time, a Piper PA-18-150, N4511Y, was destroyed when it impacted terrain while maneuvering near Daybreak Airport (WA46), La Center, Washington. The pilot was fatally injured. The airplane was registered to and operated by the pilot as a Title 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed in the area, and no flight plan was filed for the flight, which originated from Flying M Airport (OR05), Yamhill, Oregon, at 1030.
Earlier that morning, the accident pilot met with another pilot and they decided to fly around the local area as a flight of two. After departing OR05, they proceeded north and landed at Woodland State Airport (W27), Woodland, Washington. On the way to their respective home airports, they decided to fly to WA46 to conduct touch-and-go takeoffs and landings. The other pilot stated that the accident pilot departed W27 first, but when the other pilot arrived at WA46, he did not see the accident airplane in the traffic pattern. He then circled above WA46 and saw the wreckage in a wooded area near the approach end of runway 31.
A witness at WA46 stated that he saw the accident airplane climbing about 150 ft above runway 31. Near the north end of the airport, the airplane started a "low" left turn to the south. The witness estimated that the airplane leveled off about 250 ft and continued out of sight. Moments later, he heard a series of three loud bangs, followed by the sound of a full-power engine, then another loud bang followed by "an abrupt stoppage of all sound."
Review of recorded data obtained from an Appareo Stratus PRX V2 onboard the airplane revealed that the airplane departed W27 about 1250 and flew southeast while climbing to about 450 ft GPS altitude. About 1255:30, the airplane had descended to about 200 ft and entered the left downwind leg of the WA46 traffic pattern. The airplane overflew the grass runway from south to north then turned onto a left downwind leg for the runway. The airplane started to slow from 50 kts at 1256:39 and banked up to 25° right before entering the dramatic left bank. The last recorded data point was at 1256:47 and showed the airplane at a GPS altitude of 130 ft, a groundspeed of 11 knots, a pitch angle of 8°, and a left bank angle of 105°.

The wreckage was located about 530 ft from the approach end of runway 31 on a 228° bearing from the runway. The first identified point of contact (FIPC) consisted of several broken limbs at the top of a 140-ft-tall tree. A piece of the left wing landing light lens was found underneath the tree. A debris path of broken tree limbs continued on a heading about 120° to the main wreckage, which came to rest about 142 ft from the FIPC and was oriented on a heading of 270°.
The airplane impacted terrain in a nose-down attitude. The propeller hub and one blade were imbedded about 2 ft in the ground. Both blades remained attached to the hub. The fuselage came to rest on its right side and exhibited twisting throughout. The empennage remained attached to the fuselage and was bent upward. The vertical stabilizer, horizontal stabilizer, rudder, and elevators remained intact and were undamaged. Both wings and the fixed main landing gear remained attached to the fuselage. The cockpit area with the instrument panel was crushed and displaced forward into the firewall.
The propeller remained attached to the engine. The crankshaft was rotated by hand and thumb compression was obtained on all cylinders. Engine drive train continuity was established throughout. Both magnetos were rotated by hand and spark was observed at all ignition leads. The oil pickup screen was clear of debris. The carburetor was intact and remained attached to the engine. The throttle, mixture, and carburetor heat cables remained attached. The carburetor was disassembled, and no anomalies were noted.
There was no evidence of pre-impact mechanical anomalies or malfunctions of the engine or the airframe.
Medical And Pathological Information
An autopsy of the pilot was performed by the Clark County Medical Examiner, Vancouver, Washington. The autopsy report stated that the pilot's cause of death was "multiple blunt impact injuries."
The FAA's Forensic Sciences Laboratory conducted toxicology tests on specimens from the pilot. The results were negative for all tests performed.
