Narrative:
On apr/xx/96 I was on board an aircraft (C172RG) as a passenger when after the landing rollout, the pilot retracted the gear. Only the nosewheel collapsed and minimal damage was sustained. However, being a CFI, I feel confident that performing any cleanup while still on the runway is a definite no-no! If he would have waited until he was stopped on the taxiway, he may have prevented this incident. The FAA investigated the aircraft the next day. Everything was normal (given the circumstances). However, one item I would like to mention is that even though we were breaking to slow down (even more pressure on the nose gear) the squat switch never worked. The problem (I believe) was due to overcharging the strut. If it would have been properly svced, maybe 1 pilot would be without an incident. Pilot error was definitely at fault, but be aware that even though the pilot's information manual states that squat switches prevent inadvertent gear retraction while on the ground (even with excess pressure) this is just more evidence to never rely on them!
Original NASA ASRS Text
Title: PLT OF AN SMA SEL ACCIDENTALLY RETRACTED THE LNDG GEAR INSTEAD OF FLAPS UP DURING THE LNDG ROLLOUT RESULTING IN THE NOSEWHEEL ONLY COLLAPSING AND MINOR DAMAGE TO THE ACFT.
Narrative: ON APR/XX/96 I WAS ON BOARD AN ACFT (C172RG) AS A PAX WHEN AFTER THE LNDG ROLLOUT, THE PLT RETRACTED THE GEAR. ONLY THE NOSEWHEEL COLLAPSED AND MINIMAL DAMAGE WAS SUSTAINED. HOWEVER, BEING A CFI, I FEEL CONFIDENT THAT PERFORMING ANY CLEANUP WHILE STILL ON THE RWY IS A DEFINITE NO-NO! IF HE WOULD HAVE WAITED UNTIL HE WAS STOPPED ON THE TXWY, HE MAY HAVE PREVENTED THIS INCIDENT. THE FAA INVESTIGATED THE ACFT THE NEXT DAY. EVERYTHING WAS NORMAL (GIVEN THE CIRCUMSTANCES). HOWEVER, ONE ITEM I WOULD LIKE TO MENTION IS THAT EVEN THOUGH WE WERE BREAKING TO SLOW DOWN (EVEN MORE PRESSURE ON THE NOSE GEAR) THE SQUAT SWITCH NEVER WORKED. THE PROB (I BELIEVE) WAS DUE TO OVERCHARGING THE STRUT. IF IT WOULD HAVE BEEN PROPERLY SVCED, MAYBE 1 PLT WOULD BE WITHOUT AN INCIDENT. PLT ERROR WAS DEFINITELY AT FAULT, BUT BE AWARE THAT EVEN THOUGH THE PLT'S INFO MANUAL STATES THAT SQUAT SWITCHES PREVENT INADVERTENT GEAR RETRACTION WHILE ON THE GND (EVEN WITH EXCESS PRESSURE) THIS IS JUST MORE EVIDENCE TO NEVER RELY ON THEM!
