Piper PA-28-140, Thompson Aviation Services LLC, N4404T: Accident occurred February 25, 2017 at Weiser Municipal Airport (S87), Washington County, Idaho

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

NTSB Identification: GAA17CA157
14 CFR Part 91: General Aviation
Accident occurred Saturday, February 25, 2017 in Weiser, ID
Probable Cause Approval Date: 09/07/2017
Aircraft: PIPER PA 28-140, registration: N4404T
Injuries: 1 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 student pilot in the tricycle-gear-equipped airplane reported that he was flying a solo cross-country flight and landed on the 60-ft-wide asphalt runway. He recalled that there were 4-ft high snow berm that paralleled the edges of the runway. When he touched down, he applied the brakes, and the airplane yawed to the left. In fear of striking the snow berm, he initiated a go around and rotated about 65 kts. The airplane climbed about 2 ft above the runway, but the left main landing gear wheel struck the snow berm on the left side of the runway. The left tire and brake assembly separated from the airplane, and the airplane came to rest in the snow-covered safety area left of the runway. The airplane sustained substantial damage to the left wing ribs and aileron.

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

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The student pilot’s failure to maintain directional control and to maintain clearance from a snow berm during the aborted landing.

Federal Aviation Administration / Flight Standards District Office; Baltimore, Maryland
