Piper PA-28-235, N9238W: Accident occurred June 04, 2017 at Big Bear City Airport (L35), San Bernardino County, California

Aviation Accident Final Report - National Transportation Safety Board: https://app.ntsb.gov/pdf

NTSB Identification: GAA17CA354 
14 CFR Part 91: General Aviation
Accident occurred Sunday, June 04, 2017 in Big Bear, CA
Probable Cause Approval Date: 09/07/2017
Aircraft: PIPER PA28, registration: N9238W
Injuries: 2 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot reported that, during the landing flare, the airplane encountered a “sudden massive gust of wind” that pitched the nose up. He pushed the yoke forward, but the wind shifted to a tailwind, and the airplane “slammed” onto the runway. Subsequently, the left main landing gear collapsed, the airplane veered right off the runway, and it then came to rest nose down.

The airplane sustained substantial damage to the left wing.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The automated weather observation system at the airport reported that, about the time of the accident, the wind was from 260° at 4 knots. The pilot landed on runway 26. 

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s improper landing flare, which resulted in a hard landing and a subsequent loss of directional control.

Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Riverside, California
