## Sequence of events

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

- In flight collision with terrain/water, takeoff
  - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause)
  - airport facilities,runway/landing area condition - slush covered (contributing factor)
  - airport facilities,runway/landing area condition - uphill (contributing factor)
  - weather condition - high density altitude (contributing factor)
  - aborted takeoff - not performed, pilot in command (cause)
  - airspeed(vlof) - not obtained, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command
- On ground/water collision with object, takeoff - roll/run
  - object - fence (contributing factor)

## Analysis

THE PLT REPORTED THAT DURING TAKEOFF, THE ACFT SLOWED AS IT HIT PATCHES OF SLUSH. HE LIFTED OFF AT THE END OF THE RWY & RETRACTED THE GEAR WHILE IN GROUND EFFECT. THE ACFT WOULD NOT MAINTAIN FLYING SPEED & SETTLED IN SNOW. IT THEN WENT THRU A FENCE BEYOND THE END OF THE RWY. THE FIELD ELEVATION WAS 8382 FT. THE ESTIMATED DENSITY ALT WAS 9800 FT. ALSO, THE RWY HAD A 0.86% UPHILL GRADIENT.

## 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 19840210003269A](https://openairdocs.org/incident/19840210003269A), Feb 10, 1984: Mooney M20C, Angel Fire, NM, Substantial damage. Took off uphill, density altitude 9800 feet, slush on runway. Settled back on runway gear up, off end, hit fence.

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.
