NTSB Identification: GAA17CA118
14 CFR Part 91: General Aviation
Accident occurred Tuesday, January 17, 2017 in Markleeville, CA
Probable Cause Approval Date: 07/20/2017
Aircraft: CESSNA 140, registration: N5623C
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.

According to the pilot in the tailwheel-equipped airplane, during a low pass to evaluate the snow-covered runway, the airplane descended to 4 ft above ground level. The airplane encountered a crosswind from the left, and the pilot accomplished a “slip to remain over the runway.” However, the airplane descended, and the left main landing gear struck a snow berm and the airplane struck the runway and nosed over. Substantial damage was sustained to both wings, the rudder, and the horizontal stabilizer.
The pilot asserted that he should have practiced what he teaches his students and stayed 300 ft above airports when performing a fly-over.

The pilot 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 pilot’s failure to maintain altitude during a low pass and the subsequent impact with a snow berm, which resulted in a nosed-over.
