National Transportation Safety Board - Aviation Accident Factual Report

Location: Mohave, AZ
Accident Number: GAA17CA503
Date & Time: 08/19/2017, 1145 MST
Registration: N536CA
Aircraft: PIPER PA 28
Aircraft Damage: Substantial
Defining Event: Abnormal runway contact
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 

Analysis

The pilot reported that, during the approach to the desert airport, the wind had increased to about 15 knots, and it was gusting. He reported that, during landing, "a gust of wind hit me from the opposite direction of flight causing a stall." The airplane stalled about 8 ft above the runway and landed hard.

The airplane sustained substantial damage to the engine mounts.

The METAR at the nearest airport (7 miles from accident airport) reported that, about the time of the accident, the wind was from 210° at 4 knots. An hour later, the METAR reported that the wind was 10 knots, gusting to 17 knots.

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

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's improper airspeed and pitch control during landing in variable, gusting wind conditions, which resulted in an aerodynamic stall and hard landing.

Findings

Aircraft
Airspeed - Not attained/maintained (Cause)
Pitch control - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Pilot (Cause)

Environmental issues
Variable wind - Ability to respond/compensate
Gusts - Effect on operation
