## Sequence of events

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

- Main gear collapsed, taxi - to takeoff
  - landing gear,gear lever - clearance (cause)

## Analysis

THE LEFT GEAR RETRACTED. THE MODIFICATION OF THE ACFT FOR EXPERIMENTAL USE REDUCED ACCESS TO THE RUDDER TRIM CONTROL WITH THE GEAR SELECTOR IN THE DOWN POSITION. WITH THE SELECTOR IN NEUTRAL, IT WAS POSSIBLE TO APPLY LOADS TO THE GEAR WHICH REMOVED THE GEAR FROM THE POSITIVE DOWN & LOCKED POSITION. POSITIONING THE SELECTOR TO THE DOWN POSITION EXERTS 1500 PSI TOWARD THE DOWN POSITION. SUBSEQUENT TO THE ACCIDENT, THE OPERATOR RELOCATED THE RUDDER TRIM KNOB TO ALLOW RAPID 360 DEG OPERATION OF THE TRIM HANDLE WITH NO INTERFERENCE WHEN THE LANDING GEAR HANDLE IS IN THE DOWN POSITION.
