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.

On 10/22/2023 the main landing gear of privacy data omitted collapsed during landing at C80. The airplane came to rest on the fully extended nose gear and the tail section of the Cessna 172. The skid marks on the runway indicate that the main gear was not fully down and locked. The skid marks at the touchdown point show a curved pattern that reduces in width. The skid pattern is then parallel and about half the distance of the touchdown curved pattern.

The pilot’s operating handbook for this airplane recommend that the pilot check the hydraulic fluid every 25 hours. The hydraulic fluid was examined and was very low.

The pilot reported that the nose gear of this airplane is the only gear connected to the single green down light and the main gear is verified down by looking in wing mounted mirrors. The pilot’s operating handbook is not clear on how the single green light is activated. The pilot reported seeing the main gear in the wing mounted mirrors.
