## Sequence of events

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

- Loss of control - in flight, maneuvering
  - aerobatics - performed, pilot in command (contributing factor)
  - overconfidence in personal ability, pilot in command (contributing factor)
  - stall/spin - not corrected, pilot in command (cause)
  - lack of total experience in kind of aircraft, pilot in command (contributing factor)
  - aircraft weight and balance - disregarded, pilot in command (contributing factor)
  - lack of total experience in type operation, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
  - proper altitude - not maintained, pilot in command (cause)
  - clearance - not possible, pilot in command

## Analysis

THE ACFT WAS DESTROYED AS IT SPUN INTO THE GROUND AFTER HAVING BEEN OBSERVED DOING AEROBATICS BETWEEN 800 AND 1500 AGL. THE MANEUVERS INCLUDED BARREL ROLLS AND HAMMERHEAD STALLS. THE LAST MANEUVER ENDED IN A SPIN THAT WAS SAID TO LAST ABOUT5 TURNS BEFORE IMPACT. THE ACFT IMPACTED IN A NOSE LOW RIGHT WING LEADING ATTITUDE. A CALCULATON OF THE ACFT WT & BALANCE SHOWED THAT THE CG WAS AT THE AFT EDGE OF THE ALLOWABLE ENVELOPE FOR AEROBATICS. THE PLT WHO FLEW THE ACFT AN HOUR BEFORE THE ACCIDENT FLT DID NOT REVEAL ANY DEFICIENCIES. POSITIVE CONTROL IS NECESSARY FOR SPIN RECOVERY IN THIS ACFT AS OPPOSSED TO THE C-150/152 WHICH THE PLT WAS EXPERIENCED IN.

## 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 19840317058649A](https://openairdocs.org/incident/19840317058649A), Mar 17, 1984: Bbavia 8KCAB, Kiefer, OK, Destroyed, 1 fatal. Entered a spin during low level acrobatics and failed to recover. Proper control inputs for spin recovery needed.

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.
