## Probable cause

INADVERTENT STALL. FACTORS WERE THE PILOT'S OSTENTATIOUS DISPLAY AND THE LOW ALTITUDE.

## Sequence of events

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

- Loss of control - in flight, maneuvering
  - low pass - performed, pilot passenger
  - aerobatics - attempted, pilot passenger
  - ostentatious display, pilot passenger (contributing factor)
  - stall - inadvertent, pilot passenger (cause)
  - altitude - inadequate, pilot passenger (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
- Fire/explosion, other

## Analysis

THE MILITARY VINTAGE TRAINER MADE A LOW PASS OVER THE ACTIVE RUNWAY OF A LOCAL AIRPARK THAT WAS HOSTING THEIR ANNUAL FLY-IN FOR FRIENDS OF THE RESIDENTS OF THE PRIVATELY OWNED AIRPARK. THE BACK SEAT OF THE TANDEM AIRPLANE WAS OCCUPIED BY A FORMER SOVIET AIR FORCE PILOT WHO RESIDED AT THE AIRPARK AND USED TO BE AN INSTRUCTOR AND MECHANIC IN THE SAME TYPE OF AIRPLANE IN HIS NATIVE COUNTRY. AT THE COMPLETION OF THE HIGH SPEED LOW PASS, FULL POWER WAS ADDED AND THE NOSE PITCHED UP TO 35 DEGREES AS A RAPID RIGHT TURN DEVELOPED. AN ACCELERATED STALL DEVELOPED DURING THE ATTEMPTED ROLL AND THE AIRPLANE IMPACTED THE GROUND IN A NOSE DOWN ATTITUDE.
