## Probable cause

THE PILOT'S DISREGARD FOR AIRCRAFT PERFORMANCE DATA.  RELATED FACTORS ARE THE PILOT'S POOR WEATHER EVALUATION, AND DELAYED REMEDIAL ACTION.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight collision with terrain/water, descent - uncontrolled
  - weather evaluation - poor, pilot in command (contributing factor)
  - weather condition - high density altitude
  - performance data - disregarded, pilot in command (cause)
  - remedial action - delayed, pilot in command (contributing factor)
  - stall/mush - inadvertent, pilot in command
- Forced landing, descent - emergency
- Hard landing, landing - roll

## Analysis

THE PILOT STATED THE PREFLIGHT, ENGINE RUN UP AND TAKEOFF ROLL WERE NORMAL.  AFTER LIFT OFF, THE AIRCRAFT DEVELOPED A SINK RATE AND DESCENDED INTO THE GROUND.  THE PILOT REPORTED HE, 'LOST LIFT AND WAS JUST ALONG FOR THE RIDE.'  HE STATED THIS OCCURRED TO HIM BEFORE IN WARM WEATHER, AND REPORTED THERE WAS NO LOSS OF ENGINE POWER.  THE AIRCRAFT WAS WITHIN WEIGHT AND BALANCE LIMITATIONS.  DENSITY ALTITUDE WAS COMPUTED TO BE 5500 FEET AND THERE WERE THUNDERSTORMS AND SHIFTING WINDS REPORTED IN THE AREA.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19910822036859A](https://openairdocs.org/incident/19910822036859A), Aug 22, 1991: Piper PA25150, Stapleton, NE, Substantial damage. High sink rate on climbout. Dumped load. Unable recover. Stall mushed to impact. Thunderstorm in vicinity.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
