## Probable cause

PILOT IN COMMAND'S MIS-PLACEMENT OF THE AIRPLANES LANDING GEAR LEVER IN THE 'UP' POSITION WHILE THE AIRPLANE WAS ON THE GROUND, THEREBY ALLOWING THE LANDING GEAR SQUAT SWITCH, LOCATED IN THE NOSE GEAR COMPARTMENT, TO FUNCTION AS A RETRACTING CONTROLLER DURING THE SOFT FIELD TAKEOFF PROCEDURE.

## Sequence of events

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

- Nose gear collapsed, takeoff - roll/run
  - gear retraction - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, landing
  - terrain condition - runway (contributing factor)

## Analysis

UPON COMPLETION OF MAINTENANCE ON THE LANDING GEAR RETRACTION/EXTENSION PUMP THE PILOT CONDUCTED STATIC TESTS BY MOVING THE LANDING GEAR LEVER UP AND DOWN. SATISFIED WITH THE REPAIR, THE PILOT INITIATED A TEST FLIGHT BY PERFORMING A SOFT FIELD TAKEOFF. THE AIRPLANES PROPELLER BEGAN STRIKING THE RUNWAY DURING THE TAKEOFF ROLL. THE PILOT FOLLOWED THRU WITH A LIFTOFF AND DECIDED TO RETRACT THE LANDING GEAR DUE TO FEARS OF A FLIP OVER WHEN LANDING WITH A RETRACTED NOSEWHEEL. THE AIRPLANE LANDED GEAR UP ON THE DEPARTURE RUNWAY.
