## Sequence of events

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

- Loss of control - in flight, maneuvering
  - aircraft weight and balance - exceeded, pilot in command (cause)
  - overconfidence in aircraft's ability, pilot in command (contributing factor)
  - altitude - inadequate, pilot in command (cause)
  - stall - intentional, pilot in command (cause)
  - judgment - poor, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

THE ACFT WAS ESTIMATED TO BE APRX 47 LBS OVER MAX GROSS WEIGHT. THE FLT HAD LASTED ONLY ABOUT 15 MINUTES ACCORDING TO THE PASSENGER.

## 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.
