## Sequence of events

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

- Overrun, takeoff - roll/run
  - terrain condition - icy
  - aborted takeoff - delayed, pilot in command (cause)
  - airspeed - excessive, pilot in command (cause)
  - light condition - night (contributing factor)
- On ground/water collision with object, takeoff - roll/run
  - object - tree(s)

## Analysis

THE ACFT CRASHED DURING THE TAKEOFF ROLL BY RUNNING OFF THE DEPARTURE END OF THE RWY, GLIDING OVER A HWY & IMPACTING TREES. ACCORDING TO THE PLT, 'ON TAKEOFF, WE ACCELERATED TO 90-95 KTS, BUT THE ACFT DID NOT RESPOND TO BACK PRESSURE FOR LIFT OFF. WE PROCEEDED OFF THE END OF THE RWY AND OVER A ROAD. THE A/C CAME TO REST IN TREES ON THE OTHER SIDE. BRAKING TO STOP PRIOR TO REACHING END OF RWY WAS NOT POSSIBLE DUE TO ICE ON RWY.' EXAMINATION OF THE ACFT DID NOT REVEAL ANY ACFT CONTROL MALFUNCTION OR FAILURE.

## 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 19841121064409A](https://openairdocs.org/incident/19841121064409A), Nov 21, 1984: Piper PA28R201T, Anchorage, AK, Substantial damage. Autopilot inadvertently left on. Could not rotate, aborted takeoff, slid off end of icy runway, hit tree, 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.
