## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRSPEED. A FACTOR 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, approach - vfr pattern - downwind
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
  - weather condition - high density altitude (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - open field
  - weather condition - high density altitude (contributing factor)

## Analysis

A PRIVATE PILOT WAS FLYING HIS RECENTLY PURCHASED GYROCOPTER IN THE TRAFFIC PATTERN. A WITNESS REPORTED HEARING A POWER REDUCTION WHILE THE GYROCOPTER WAS ON A HIGH DOWNWIND. AIRSPEED WAS NOT MAINTAINED AND THE ROTOR RPM DECAYED TO THE POINT WHERE THE NOSE PITCHED DOWN AS THE GYROCOPTER ROLLED TO THE LEFT IN AN UNCONTROLLED DESCENT TO THE GROUND. DENSITY ALTITUDE WAS 6600 FEET.

## 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 19920829033919A](https://openairdocs.org/incident/19920829033919A), Aug 29, 1992: Amtrac ELITE532, Dumas, TX, Destroyed, 1 fatal. Slowed circling airport on first flight of newly purchased gyrocopter. Began rotating and dived into ground.

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.
