The nose gear collapsed on a piper PA44, seminole during landing roll resulting in the pilot losing directional control of the aircraft and running off the side of the runway. The main gears also both collapsed when the aircraft went off the side of the runway. Pilot states that he observed 3 green gear down indicator lights just prior to landing.

Narrative:

After a normal touchdown and during rollout the nosewheel collapsed, the aircraft started pulling to the left at which time I applied right brake, this slowed the turn down. Our speed at this time would have been about 40 KTS or less. Just prior to going off the runway the left gear began to retract and had marks on the wheel cover and on the outside of the gear door, the right gear retracted in the soft ground with no marks on the outside of the wheel or gear door. Gear lights were green over the power lines prior to touchdown. All corrective action was taken in our opinion. Aircraft was prevented from veering off sharply to the left by opposite braking.

Title: THE NOSE GEAR COLLAPSED ON A PIPER PA44, SEMINOLE DURING LNDG ROLL RESULTING IN THE PLT LOSING DIRECTIONAL CTL OF THE ACFT AND RUNNING OFF THE SIDE OF THE RWY. THE MAIN GEARS ALSO BOTH COLLAPSED WHEN THE ACFT WENT OFF THE SIDE OF THE RWY. PLT STATES THAT HE OBSERVED 3 GREEN GEAR DOWN INDICATOR LIGHTS JUST PRIOR TO LNDG.

Narrative: AFTER A NORMAL TOUCHDOWN AND DURING ROLLOUT THE NOSEWHEEL COLLAPSED, THE ACFT STARTED PULLING TO THE L AT WHICH TIME I APPLIED R BRAKE, THIS SLOWED THE TURN DOWN. OUR SPD AT THIS TIME WOULD HAVE BEEN ABOUT 40 KTS OR LESS. JUST PRIOR TO GOING OFF THE RWY THE L GEAR BEGAN TO RETRACT AND HAD MARKS ON THE WHEEL COVER AND ON THE OUTSIDE OF THE GEAR DOOR, THE R GEAR RETRACTED IN THE SOFT GND WITH NO MARKS ON THE OUTSIDE OF THE WHEEL OR GEAR DOOR. GEAR LIGHTS WERE GREEN OVER THE PWR LINES PRIOR TO TOUCHDOWN. ALL CORRECTIVE ACTION WAS TAKEN IN OUR OPINION. ACFT WAS PREVENTED FROM VEERING OFF SHARPLY TO THE L BY OPPOSITE BRAKING.
