## Probable cause

THE INSTRUCTOR PILOT'S (CFI'S) IMPROPER SUPERVISION OF FLIGHT AND A FAILURE TO MAINTAIN SUFFICIENT ALTITUDE ABOVE THE TREES.

## Sequence of events

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

- In flight collision with object, maneuvering
  - supervision - improper, pilot in command(cfi) (cause)
  - tree(s) - tree(s)
  - proper altitude - not maintained (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE INSTRUCTOR PILOT (CFI) AND STUDENT WERE ON AN INSTRUCTIONAL FLIGHT IN VFR CONDITIONS.  A WITNESS SAW AND HEARD THE AIRPLANE FLYING EASTBOUND.  SHORTY THEREAFTER, THE AIRPLANE CRASHED ON A SOUTHERLY HEADING.  THERE WAS EVIDENCE THAT INITIAL IMPACT OCCURRED, WHEN THE RIGHT WING TIP COLLIDED WITH TREETOPS. THE AIRPLANE REMAINED AIRBORNE FOR A DISTANCE, THEN CRASHED IN A STEEP DESCENT AFTER TRAVELING ABOUT 330 FT FROM WHERE THE FIRST PIECE OF THE WING TIP WAS FOUND.  NO PREIMPACT PART FAILURE OR MALFUNCTION OF THE AIRCRAFT OR ENGINE WAS FOUND.
