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.
