## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - aircraft performance,climb capability - exceeded (cause)
  - performance data - not understood, pilot in command (cause)
  - weather condition - high density altitude (contributing factor)
  - weather evaluation - not attained, pilot in command (cause)
  - judgment - improper, pilot in command (cause)
  - preflight planning/preparation - inadequate, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing - flare/touchdown
  - terrain condition - rising (contributing factor)

## Analysis

ON JUNE 22, 1985, A ROCKWELL AEROCOMMANDER 112 IMPACTED THE GROUND IMMEDIATELY AFTER TAKEOFF. THE DENSITY ALT WAS 7700 FT. AFTER TAKEOFF THE PLT REALIZED THE ACFT WOULD NOT CLEAR A RIDGETOP. THE ACFT BEGAN TO DESCEND & WAS MANEUVERED TO LAND ON LEVEL TERRAIN. A WINTESS SAID HE KNEW THE ACFT DID NOT HAVE ENOUGH SPEED TO TAKEOFF.

## 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 19850622030429A](https://openairdocs.org/incident/19850622030429A), Jun 22, 1985: Gulstm 112, Lander, WY, Destroyed. High density altitude on takeoff. Unable to clear rising terrain.

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.
