## Probable cause

THE PILOT IN COMMAND'S INTENTIONAL BUZZING AND FAILURE TO MAINTAIN AIRSPEED, RESULTING IN INADVERTENT STALL. DURING THE UNCONTROLLED DESCENT, THE AIRPLANE COLLIDED WITH AND REMAINED SUSPENDED IN A TREE. CONTRIBUTING TO THE ACCIDENT WAS THE OSTENTATIOUS DISPLAY BY THE PILOT AND UNSUITABLE TERRAIN ENCOUNTERED.

## Sequence of events

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

- Loss of control - in flight, climb
  - buzzing - intentional, pilot in command (cause)
  - ostentatious display, pilot in command (contributing factor)
  - airspeed(vs) - not maintained, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command
- In flight collision with object, descent - uncontrolled
  - object - tree(s)

## Analysis

THE ACFT WAS MANEUVERING OVER HOUSES.  THEN, WHILE FLYING TOWARD RISING TERRAIN TO DEPART, THE ACFT STALLED AND COLLIDED WITH AND REMAINED SUSPENDED IN A TREE.  COMPLAINTS WERE MADE TO THE LOCAL POLICE DEPARTMENT SEVERAL MINUTES BEFORE THE ACCIDENT ABOUT A LOW FLYING ACFT.
