## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AN AIRSPEED ABOVE THE STALL SPEED FOR THE AIRCRAFT.  CONTRIBUTING TO THE ACCIDENT WAS THE HIGH DENSITY ALTITUDE.

## Sequence of events

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

- Loss of control - in flight, maneuvering - turn to reverse direction
  - airspeed(vs) - not maintained, pilot in command (cause)
  - weather condition - high density altitude (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

DURING AN ATTEMPTED TURN TO REVERSE COURSE IN RISING TERRAIN AND IN HIGH DENSITY ALTITUDE CONDITIONS THE AIRCRAFT STALLED.  THE PILOT HAD ATTEMPTED TO GAIN ALTITUDE BY DOING A TOUCH AND GO ON A ROAD JUST BEFORE HE ATTEMPTED THE COURSE REVERSAL.

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

- [Accident 19910522016819A](https://openairdocs.org/incident/19910522016819A), May 22, 1991: Piper PA22135, Laramie, WY, Substantial damage. Unable to climb through a pass,touched down on highway then initiated a climb. Stalled trying to make a 180 turn.

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.
