## Sequence of events

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

- Loss of control - in flight, maneuvering - turn to reverse direction
  - in-flight planning/decision - poor, pilot in command (cause)
  - low pass - intentional, pilot in command (cause)
  - stall - uncontrolled, pilot in command (cause)
- In flight collision with terrain/water, maneuvering - turn to reverse direction
  - terrain condition - rising (contributing factor)

## Analysis

PRIOR TO THE ACCIDENT, THE STUDENT PILOT WAS OBSERVED PERFORMING POWER-ON STALLS AT LOW ALTITUDE WITH PASSENGERS ON BOARD. THE STALLS WERE BEING MADE TOWARD RAPIDLY RISING TERRAIN IN A MOUNTAINOUS AREA. AFTER THE LAST RECOVERY, THE AIRCRAFT WAS OBSERVED TURNING WHEN IT STALLED AGAIN AND COLLIDED WITH A MOUNTAINSIDE. NO PREIMPACT/MECHANICAL FAILURES OR MALFUNCTIONS WERE FOUND.
