## Probable cause

THE PILOT'S INADEQUATE PLANNING AND PREPARATION FOR THE FLIGHT WHICH RESULTED IN INADEQUATE AIRSPEED AND AN INADVERTENT STALL WHILE ATTEMPTING TO CLEAR TREES OFF THE END OF THE RUNWAY. CONTRIBUTING FACTORS WERE: THE HIGH DENSITY ALTITUDE, GUSTY CROSSWIND, UPSLOPING RUNWAY, AND HIGH OBSTRUCTIONS OFF THE END OF THE RUNWAY.

## 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
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - airport facilities,runway/landing area condition - uphill (contributing factor)
  - weather condition - high density altitude (contributing factor)
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - terrain condition - high obstruction(s) (contributing factor)
  - terrain condition - rising (contributing factor)
  - airspeed - inadequate, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, takeoff - initial climb

## Analysis

TAKEOFF WAS FROM A CLOSED RUNWAY WITH MEN & EQUIPMENT WORKING ON THE FIRST 600 FT REPAVING. THE AIRPORT FACILITY DIRECTORY STATED 'TAKEOFF NORTH HAZARDOUS, DOWNDRAFTS AND CROSSWINDS, HILLS AND TREES'. UPSLOPING RUNWAY. DENSITY ALT WAS ABOUT 6300 FT, AND THERE WERE GUSTY CROSSWINDS. PASSENGERS REPORTED THE STALL WARNING HORN ACTIVATED JUST AFTER LIFT-OFF & WAS ON UNTIL THE AIRCRAFT IMPACTED TREES.

## 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 19890623017389A](https://openairdocs.org/incident/19890623017389A), Jun 23, 1989: Piper PA28181, Chiloguin, OR, Destroyed. Tried to depart a closed runway, uphill, near gross weight, high density altitude. Crashed in trees on climbout.

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.
