## Probable cause

THE PILOT IN COMMAND'S FAILURE TO MAINTAIN VISUAL LOOKOUT AND CLEARANCE FROM TERRAIN. A FACTOR WAS THE PILOT DIVERTED HIS ATTENTION TO SECURE A LOOSE FIRE EXTINGUISHER.

## Sequence of events

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

- In flight collision with terrain/water, cruise
  - fire extinguisher,portable - loose (contributing factor)
  - diverted attention, pilot in command (contributing factor)
  - visual lookout - not maintained, pilot in command (cause)
  - clearance - not maintained, pilot in command (cause)

## Analysis

THE PILOT BENT DOWN TO RETRIEVE THE FIRE EXTINGUISHER BETWEEN HIS FEET AND TO REPLACE IT IN THE BRACKET LOCATED UNDER THE PILOT'S SEAT.  WHEN HE LOOKED UP HE SAW A HILL IN FRONT OF THE AIRPLANE.  HE PULLED UP AND THE AIRPLANE STRUCK THE HILL BUT CONTINUED TO FLY.  HE PULLED BACK ON THE YOKE AND ADDED FULL POWER AND THE AIRPLANE ENTERED THE CLOUDS.  HE NOTICED HE WAS ABOUT TO STALL THE AIRPLANE SO HE LOWERED THE NOSE AND THE AIRPLANE IMMEDIATELY STRUCK THE HILL AGAIN AND NOSED OVER.
