## Sequence of events

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

- Loss of control - in flight, takeoff
  - airport facilities,runway/landing area condition - rough/uneven (contributing factor)
  - weather condition - high density altitude (contributing factor)
  - elevator - excessive, pilot in command (contributing factor)
  - lift-off - premature, pilot in command (cause)
  - airspeed(vso) - not attained, pilot in command (cause)
  - remedial action - performed, pilot in command
- Gear collapsed, takeoff
  - landing gear,nose gear - overload
  - directional control - not maintained, pilot in command (cause)
  - proper alignment - not attained, pilot in command (cause)

## Analysis

PLT INITIATED TAKE-OFF FROM ROUGH, 2800 FT SOD STRIP IN LIGHT WIND CONDITIONS AND KNOWN HIGH DENSITY ALT SITUATION. SLIGHT BACK YOKE PRESSURE WAS BEING USED DURING TAKEOFF ROLL TO MODERATE EFFECT OF ROUGH SURFACE ON NOSE GEAR. ADDITIONAL BACK PRESSURE WAS APPLIED, THE ACFT BECAME AIRBORNE BELOW MIN STEADY FLT CONTROL SPEED AND RIGHT WING DROPPED. THE PLT LOWERED THE NOSE TO RE-LAND THE ACFT BUT TOUCHED DOWN IN A SKID. GEAR COLLAPSED DUE TO SIDE LOADS AND ROUGH TERRAIN.

## 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 19840831045739A](https://openairdocs.org/incident/19840831045739A), Aug 31, 1984: Beech 58, Bridgeport, NE, Substantial damage. Yawed and impacted ground at liftoff. Gear collapsed on rough sod runway. Density altitude a factor.

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.
