## 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
  - weather condition - crosswind (contributing factor)
  - lift-off - premature, pilot in command (contributing factor)
  - directional control - not maintained, pilot in command (contributing factor)
  - remedial action - uncontrolled, pilot in command (cause)
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE ACFT SUSTAINED SUBSTANTIAL DAMAGE AFTER IT STALLED AND CONTACTED THE GROUND DURING TAKEOFF. PLT STATED LIFT OFF WAS MADE WITH MINIMAL AIRSPEED AND THE RIGHT WING DROPPED SHORTLY AFTER BECOMING AIRBORNE. PLT OVERCORRECTED FOR THE RIGHT BANK, THE ACFT BANKED LEFT AND THE PITCH ATTITUDE INCREASED UNTIL A STALL RESULTED.

## 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.
