## 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)
  - weather condition - high density altitude (contributing factor)
  - aircraft weight and balance - excessive, pilot in command (contributing factor)
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, takeoff

## Analysis

THE PLT TOOK OFF WITH A NEAR FULL LOAD OF FUEL. AN ADULT PASSENGER WAS IN THE RIGHT SEAT & A CHILD WAS SEATED IN THE BAGGAGE COMPARTMENT, WHICH WAS NOT AN APPROVED SEAT. THE DENSITY ALTITUDE AT THE ARPT WAS APRX 4100 FT. THE PLT INDICATED THAT HE ROTATED FOR LIFT OFF AT THE PROPER SPEED. HOWEVER, AFTER LIFT-OFF, THE ACFT WAS CLIMBING SLOWLY WHEN THE RIGHT WING DIPPED, FOLLOWED BY THE LEFT WING. THE ACFT THEN MUSHED & STRUCK THE RWY NOSEWHEEL 1ST. SUBSEQUENTLY, THE ACFT CAME TO REST, OFF TO THE RIGHT SIDE OF THE RWY IN A FIELD. THE ACFT WAS ESTIMATED TO BE ABOVE ITS MAX GROSS WT LIMIT.

## 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 19830828048249A](https://openairdocs.org/incident/19830828048249A), Aug 28, 1983: Gulstm AA1B, Bucklin, KS, Substantial damage. Aircraft stalled and crashed right after liftoff. Had unauthorized passenger in baggage compartment.

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.
