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) N760X gear would not extend. The pilot tried the emergency extension system which also failed. The pilot elected to land gear up, and gently settled the aircraft onto runway 25. The aircraft was lifted with airbags, and it was determined that the right main gear outboard gear door roller would not release from the door uplock track. When manually released, the gear fell and locked down. Damage is limited to the belly skins, and several formers under the center section and left/right flap inboard foot on the trailing edges. No major structural damage seen, the pressure vessel is up at the cabin floor, not the belly skin. It broke off 8 antennas, slight buckling at one belly former. No FOD damage seen in either engine inlet, but they must be checked. Owner is going to have two experienced MS-760 mechanics look at the aircraft and make it ferry capable for repair.
