Location: Yellow Pine, Idaho
Accident Number: WPR20CA198
Date & Time: June 24, 2020, 08:30 Local 
Registration: N288BC
Aircraft: Maule M7
Aircraft Damage: Substantial
Defining Event: Hard landing
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal

Analysis

The pilot of the tailwheel-equipped airplane decided to land on the airstrip following several successful landings on less challenging back country airstrips. During the approach into the steep, upsloping landing area, the pilot carried more airspeed with the intention of allowing the flare and upslope to arrest the airplane’s forward momentum. The pilot stated that the airplane was too fast and that his flare was not adequate when he touched down further down the airstrip than anticipated and the airplane bounced. When the airplane contacted the ground again, he applied maximum braking as he approached an oncoming cliff at the end of the airstrip, and the airplane nosed over. The airplane sustained substantial damage to the right-wing lift strut and rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions 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 approach airspeed and landing flare, which resulted in a bounced landing, and subsequent nose over. 

Findings

Aircraft Airspeed - Incorrect use/operation
Aircraft Landing flare - Not attained/maintained
Personnel issues Aircraft control - Pilot

Flight Conducted Under: Part 91: General Aviation - Personal

Analysis

The pilot of the tailwheel-equipped airplane reported that he landed in a field that had numerous gopher holes and mounds. During the landing roll, the main landing gear encountered a soft spot in the terrain and the airplane nosed over. The airplane sustained substantial damage to the left wing strut, rudder, and horizontal stabilizer.

The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine 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 selection of unsuitable terrain for landing, which resulted in a nose over.

  1. Can you stub a giant turf tire in a gopher hole? (none are visible). Looks like maybe he put on too much brake, or perhaps a hole/mound lofted a wheel and it locked up before recontact.
