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.

After lowering the gear on down wind for rwy 30. The pilot landed the airplane with full flaps and started to flare over the numbers. The pilot reported it was on, OR just after touching down, that he felt the RH MLG collapse causing the right wing tip to drag on the rwy resulting in the airplane veering to the right and departing the rwy within 80 feet of touchdown and impacting a rwy light at the RH lwer nose cowl. The side- loading on the LH MLG caused it and the NLG to collapse as well. The pilot initially reported he saw a green light prior to landing indicating all three gear down and locked. When questioned the day after the incident he could not remember whether the light was green or not. He did remember lowering the gear however. No injuries reported. Post incident maintenance investigation revealed a broken RH outboard gear retraction arm. The arm attaches to a cable that holds the overcenter mechanism in place while the gear is extended. When the arm broke it allowed the RH MLG to come out of the overcenter position and colapse. The cable also holds the NLG overcenter mechanism in place which resulted in the NLG collapse and the LH MLG collapse from side loading.

As the FAA filed it

AFTER LOWERING THE GEAR ON DOWN WIND FOR RWY 30. THE PILOT LANDED THE AIRPLANE WITH FULL FLAPS AND STARTED TO FLARE OVER THE NUMBERS. THE PILOT REPORTED IT WAS ON, OR JUST AFTER TOUCHING DOWN, THAT HE FELT THE RH MLG COLLAPSE CAUSING THE RIGHT WING TIP TO DRAG ON THE RWY RESULTING IN THE AIRPLANE VEERING TO THE RIGHT AND DEPARTING THE RWY WITHIN 80 FEET OF TOUCHDOWN AND IMPACTING A RWY LIGHT AT THE RH LWER NOSE COWL. THE SIDE- LOADING ON THE LH MLG CAUSED IT AND THE NLG TO COLLAPSE AS WELL. THE PILOT INITIALLY REPORTED HE SAW A GREEN LIGHT PRIOR TO LANDING INDICATING ALL THREE GEAR DOWN AND LOCKED. WHEN QUESTIONED THE DAY AFTER THE INCIDENT HE COULD NOT REMEMBER WHETHER THE LIGHT WAS GREEN OR NOT. HE DID REMEMBER LOWERING THE GEAR HOWEVER. NO INJURIES REPORTED. POST INCIDENT MAINTENANCE INVESTIGATION REVEALED A BROKEN RH OUTBOARD GEAR RETRACTION ARM. THE ARM ATTACHES TO A CABLE THAT HOLDS THE OVERCENTER MECHANISM IN PLACE WHILE THE GEAR IS EXTENDED. WHEN THE ARM BROKE IT ALLOWED THE RH MLG TO COME OUT OF THE OVERCENTER POSITION AND COLAPSE. THE CABLE ALSO HOLDS THE NLG OVERCENTER MECHANISM IN PLACE WHICH RESULTED IN THE NLG COLLAPSE AND THE LH MLG COLLAPSE FROM SIDE LOADING.
