## Probable cause

INADVERTENT STALL DURING INITIAL CLIMB FOLLOWING TAKEOFF.

## 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
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - rising (contributing factor)

## Analysis

THE AIRCRAFT WAS DEPARTING ON A CROSS COUNTRY FLIGHT FROM AN AIRPORT AT 6,000 FEET ABOVE SEA LEVEL.  THE DENSITY ALTITUDE WAS 9,000 FEET AND THE AIRCRAFT WAS ESTIMATED TO BE AT OR NEAR MAXIMUM GROSS WEIGHT.  THE RUNWAY SLOPED UP AND THE TERRAIN OFF THE END OF THE RUNWAY SLOPED UP.  THE AIRCRAFT BECAME AIRBORNE, CLIMBED TO APPROXIMATELY 50 FEET AND THEN SETTLED.  THE PILOT ESTIMATED THAT THE AIRCRAFT STALLED AT APPROXIMATELY 35 FEET AND IMPACTED OFF THE END OF THE RUNWAY.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
