From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Aircraft was landing at Payson when the nose gear collapsed during roll out. Right hand main landing gear collapsed and aircraft veered off runway 24 to the right hand side of the runway. Extensive damage sustained to lower nose bowl skins & lower bulkheads forward of nose landing gear well; both right hand & left hand propeller blades were curled back at tips; right hand inboard landing gear door had been torn off during the landing; right hand outboard leading edge dented in toward spar just at the last foot of the outboard de-ice boot with skin scrapes on lower outboard wing tip and the most outboard lower wing skin.

Further investigation the next day determined the nose gear extension fitting had failed at the nose gear actuator arm attach bolt hole, allowing the nose gear to move backwards and fold up upon landing. This in turn unlocked the right hand gear leg and it collapsed inboard allowing the aircraft to settle down onto the nose and the right hand gear leg and wing tip prior to the aircraft coming to a full stop.

The pilot stated that he landed as normal and then when the nose gear touched down the gear slowly started to lower. There was nothing he could do other than to shut the engines down and egress the aircraft.

As the FAA filed it

AIRCRAFT WAS LANDING AT PAYSON WHEN THE NOSE GEAR COLLAPSED DURING ROLL OUT. RIGHT HAND MAIN LANDING GEAR COLLAPSED AND AIRCRAFT VEERED OFF RUNWAY 24 TO THE RIGHT HAND SIDE OF THE RUNWAY. EXTENSIVE DAMAGE SUSTAINED TO LOWER NOSE BOWL SKINS & LOWER BULKHEADS FORWARD OF NOSE LANDING GEAR WELL; BOTH RIGHT HAND & LEFT HAND PROPELLER BLADES WERE CURLED BACK AT TIPS; RIGHT HAND INBOARD LANDING GEAR DOOR HAD BEEN TORN OFF DURING THE LANDING; RIGHT HAND OUTBOARD LEADING EDGE DENTED IN TOWARD SPAR JUST AT THE LAST FOOT OF THE OUTBOARD DE-ICE BOOT WITH SKIN SCRAPES ON LOWER OUTBOARD WING TIP AND THE MOST OUTBOARD LOWER WING SKIN.

FURTHER INVESTIGATION THE NEXT DAY DETERMINED THE NOSE GEAR EXTENSION FITTING HAD FAILED AT THE NOSE GEAR ACTUATOR ARM ATTACH BOLT HOLE, ALLOWING THE NOSE GEAR TO MOVE BACKWARDS AND FOLD UP UPON LANDING. THIS IN TURN UNLOCKED THE RIGHT HAND GEAR LEG AND IT COLLAPSED INBOARD ALLOWING THE AIRCRAFT TO SETTLE DOWN ONTO THE NOSE AND THE RIGHT HAND GEAR LEG AND WING TIP PRIOR TO THE AIRCRAFT COMING TO A FULL STOP.

THE PILOT STATED THAT HE LANDED AS NORMAL AND THEN WHEN THE NOSE GEAR TOUCHED DOWN THE GEAR SLOWLY STARTED TO LOWER. THERE WAS NOTHING HE COULD DO OTHER THAN TO SHUT THE ENGINES DOWN AND EGRESS THE AIRCRAFT.
