## Sequence of events

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

- Loss of control - in flight, maneuvering
  - procedures/directives - not followed, pilot in command (cause)
  - improper use of procedure, pilot in command (contributing factor)
  - airspeed - not maintained, pilot in command (cause)
  - clearance - not maintained, pilot in command (cause)

## Analysis

THE PILOT STALLED THE AIRPLANE WHILE MAKING A STEEP TURN TO AVOID HIGH VOLTAGE POWER LINES. THE AIRPLANE CAUGHT FIRE ON IMPACT AND THE AIR TAXI PILOT SUBSEQUENTLY DIED OF EXTENSIVE THERMAL INJURIES. THE PLT WAS FLYING IN FORMATION WITH ANOTHER ACFT AT LOW ALT. WHEN THE PWR LINES WERE SIGHTED THE OTHER ACFT SUCCESSFULLY PULLED UP AND AVOIDED THE WIRES. THE ACC PLT TURNED STEEPLY AND LOST CONTROL OF THE ACFT BEFORE CRASHING.
