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.

Narrative: the pilot stated, after touch down and during landing roll-out, the landing gear collapsed. The pilot also stated that the landing gear (green) down and locked indication light was on. The passenger stated, the landing appeared to be normal through touchdown and initial rollout. After several seconds, the nose dropped and the prop hit the runway. Apparently the nose gear had collapsed. He stated, he noted no unusual indications before the nose dropped. At start of the investigation, it was noted that the flaps had received no damage and the landing gear circuit breaker was popped. With the aircraft on jacks, the circuit breaker was reset, electrical power applied and the left gear went to down and locked position and the circuit breaker popped. Further investigation revealed both main landing gear control rods (p/n 560244-5001) were bent, (enabling the adjustable tabs to make contact with the landing gear system cutout/down and lock switch) and the nose gear trust retract assembly (PN540016-507) control rod attach point rods were broken. The main landing gear control rods were removed, straightened and temporarily re-installed and the gear system worked normal. This incident is being further investigated by operations for possible improper operating procedures.

As the FAA filed it

NARRATIVE: THE PILOT STATED, AFTER TOUCH DOWN AND DURING LANDING ROLL-OUT, THE LANDING GEAR COLLAPSED. THE PILOT ALSO STATED THAT THE LANDING GEAR (GREEN) DOWN AND LOCKED INDICATION LIGHT WAS ON. THE PASSENGER STATED, THE LANDING APPEARED TO BE NORMAL THROUGH TOUCHDOWN AND INITIAL ROLLOUT. AFTER SEVERAL SECONDS, THE NOSE DROPPED AND THE PROP HIT THE RUNWAY. APPARENTLY THE NOSE GEAR HAD COLLAPSED. HE STATED, HE NOTED NO UNUSUAL INDICATIONS BEFORE THE NOSE DROPPED. AT START OF THE INVESTIGATION, IT WAS NOTED THAT THE FLAPS HAD RECEIVED NO DAMAGE AND THE LANDING GEAR CIRCUIT BREAKER WAS POPPED. WITH THE AIRCRAFT ON JACKS, THE CIRCUIT BREAKER WAS RESET, ELECTRICAL POWER APPLIED AND THE LEFT GEAR WENT TO DOWN AND LOCKED POSITION AND THE CIRCUIT BREAKER POPPED. FURTHER INVESTIGATION REVEALED BOTH MAIN LANDING GEAR CONTROL RODS (P/N 560244-5001) WERE BENT, (ENABLING THE ADJUSTABLE TABS TO MAKE CONTACT WITH THE LANDING GEAR SYSTEM CUTOUT/DOWN AND LOCK SWITCH) AND THE NOSE GEAR TRUST RETRACT ASSEMBLY (PN540016-507) CONTROL ROD ATTACH POINT RODS WERE BROKEN. THE MAIN LANDING GEAR CONTROL RODS WERE REMOVED, STRAIGHTENED AND TEMPORARILY RE-INSTALLED AND THE GEAR SYSTEM WORKED NORMAL. THIS INCIDENT IS BEING FURTHER INVESTIGATED BY OPERATIONS FOR POSSIBLE IMPROPER OPERATING PROCEDURES.
