## Sequence of events

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

- In flight collision with terrain/water, go-around (vfr)
  - weather condition - high density altitude (contributing factor)
  - in-flight planning/decision - inadequate, pilot in command (cause)
  - overconfidence in aircraft's ability, pilot in command (contributing factor)
  - airspeed - not maintained, pilot in command (contributing factor)
  - stall/mush - inadvertent, pilot in command (cause)
  - remedial action - delayed, pilot in command (cause)

## Analysis

THE PILOT WAS FLYING A PATTERN AROUND A FIELD WHERE HE INTENDED TO LAND LATER. DURING A LOW PASS, HE APPLIED POWER FOR A GO- AROUND BUT FULL POWER WAS NOT SUFFICIENT TO PREVENT A TOUCHDOWN. AT TOUCHDOWN, A SIDE LOAD COLLAPSED THE LANDING GEAR. THE PILOT IS ALSO A MECHANIC AND WAS UNABLE TO DETERMINE ANY ENGINE PROBLEMS DURING A POST-IMPACT EXAMINATION. THE FIELD ELEVATION WAS 1649 FEET ASL AND THE DENSITY ALTITUDE WAS 3700 FEET.

## 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 19860817058519A](https://openairdocs.org/incident/19860817058519A), Aug 17, 1986: Bbavia 7AC, Republic, MO, Substantial damage. Go around from low pass over intended landing site was sluggish. Sideloads collapsed landing gear at touchdown.

## Other investigations on N84055 (1)

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.
