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.

(-23) During an inspection of the accident aircraft the following items were noted: 1. The right hand wing strut damaged due to striking of runway sign during roll out. 2. The nose landing gear torque link required replacement. 3. The nose gear strut required resealing and servicing. The original report for this accident indicated that the pilot reported that the bolt for the nose torque strut had fallen out during the flight and that was the reason they lost directional control. This is consistent with the evidence. Had the bolt fallen out during flight, the upper snap ring securing the strut would not be sufficient to hold back the pressure and the nose lower strut would have departed the aircraft. Another issue was that the bushing for the torque link was deformed consistent with a fracture of the bolt on landing. This could be caused by a nose gear landing first with the gear turned. Witness had stated that they had seen the aircraft practicing crosswind landings. Based on the damage to the aircraft the most likely cause for this damage would be a hard, nose first, cross wind landing.

As the FAA filed it

(-23) DURING AN INSPECTION OF THE ACCIDENT AIRCRAFT THE FOLLOWING ITEMS WERE NOTED: 1. THE RIGHT HAND WING STRUT DAMAGED DUE TO STRIKING OF RUNWAY SIGN DURING ROLL OUT. 2. THE NOSE LANDING GEAR TORQUE LINK REQUIRED REPLACEMENT. 3. THE NOSE GEAR STRUT REQUIRED RESEALING AND SERVICING. THE ORIGINAL REPORT FOR THIS ACCIDENT INDICATED THAT THE PILOT REPORTED THAT THE BOLT FOR THE NOSE TORQUE STRUT HAD FALLEN OUT DURING THE FLIGHT AND THAT WAS THE REASON THEY LOST DIRECTIONAL CONTROL. THIS IS CONSISTENT WITH THE EVIDENCE. HAD THE BOLT FALLEN OUT DURING FLIGHT, THE UPPER SNAP RING SECURING THE STRUT WOULD NOT BE SUFFICIENT TO HOLD BACK THE PRESSURE AND THE NOSE LOWER STRUT WOULD HAVE DEPARTED THE AIRCRAFT. ANOTHER ISSUE WAS THAT THE BUSHING FOR THE TORQUE LINK WAS DEFORMED CONSISTENT WITH A FRACTURE OF THE BOLT ON LANDING. THIS COULD BE CAUSED BY A NOSE GEAR LANDING FIRST WITH THE GEAR TURNED. WITNESS HAD STATED THAT THEY HAD SEEN THE AIRCRAFT PRACTICING CROSSWIND LANDINGS. BASED ON THE DAMAGE TO THE AIRCRAFT THE MOST LIKELY CAUSE FOR THIS DAMAGE WOULD BE A HARD, NOSE FIRST, CROSS WIND LANDING.
