BEECH A-90
AFTER THE PLT PLACED THE MASTER SWITCH ON TO START THE ENGINES THE LANDING GEAR COLLAPSED. HE STATED THAT THE PASSENGER, IN THE CO-PLT SEAT, BUMPED THE LANDING GEAR HANDLE INTO THE UP POSITION. THE PASSENGER STATED THAT HE DID NOT. INSP OF THE ACFT REVEALED THAT THE LANDING GEAR HANDLE WAS IN THE DOWN POSITION & THAT THE RT GEAR SAFETY SWITCH FAILED INTERNALLY. FAILURE OF THE SWITCH WILL NOT CAUSE THE GEAR TO COLLAPSE UNLESS THE LANDING GEAR HANDLE IS PLACED IN THE UP POSITION. THE LANDING GEAR HANDLE IS DESIGNED SO THAT IT MUST BE PULLED OUT THEN PUSHED UP TO RETRACT THE LANDING GEAR. NO DETERMINATION COULD BE MADE AS TO WHO PLACED THE LANDING GEAR HANDLE UP PRIOR TO TURNING ON THE MASTER SWITCH.
