Investigation Docket - National Transportation Safety Board: https://data.ntsb.gov/Docket
Location: Talkeetna, Alaska
Accident Number: ANC21LA054
Date and Time: July 1, 2021, 14:45 Local
Registration: N8996Y
Aircraft: Piper PA-18-150
Aircraft Damage: Substantial
Defining Event: Nose over/nose down
Injuries: 2 None
Flight Conducted Under: Part 91: General aviation - Instructional
Analysis
The flight instructor reported that after evaluating an uphill off-airport landing site, the pilot receiving instruction proceeded with an approach to landing. The airplane touched down long due to excessive airspeed and a gusty tailwind. During the landing rollout, and as the airplane neared the crest of the hill, excessive braking was applied and the airplane subsequently nosed-over resulting in substantial damage to the right lift strut and rudder. The pilot reported that there were no preaccident mechanical malfunctions or anomalies 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 excessive use of brakes during landing, which resulted in a nose-over. Contributing to the accident was the flight instructor’s inadequate supervision and the gusty tailwind conditions.
Findings
Aircraft Brake - Incorrect use/operation
Aircraft Surface speed/braking - Incorrect use/operation
Personnel issues Use of equip/system - Student/instructed pilot
Personnel issues Delayed action - Instructor/check pilot
