What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On March 12, 2025, at around 2050 MST, a Cessna 172 departed double eagle airport enroute to demming, NM on a personal flight, visual meteorologic conditions prevailed at the time. While enroute the pilot began experiencing excessive engine vibration. The pilot declared an inflight emergency and landed the aircraft safely at the Truth Or Consequences Municipal Airport. The pilot stated it was windy, cold and dark but a postflight inspection was performed. A large quantity of oil was observed on the engine and the inside of the engine cowling. She did not see any damage to the engine firewall.
On April 2, 2025, we traveled to Truth Or Consequences Municipal Airport to inspect the aircraft. The engine firewall was observed dented above the nose landing gear attaching point and multiple rivets were sheared off an attaching l-bracket on the engine firewall.
This occurrence was upgraded to an incident on April 3, 2025, based upon the damage to the aircraft
On April 7, 2025, we contacted the airframe and powerplant technician who performed a postflight inspection of the aircraft. He determined the cause of engine vibration was a severe oil leak caused by a failed gasket at the oil filter adapter and the engine case. He also observed the engine firewall dented above the nose landing gear attaching point and multiple rivets attaching an l-bracket to the firewall was sheared off exposing clean surface material compared to the surrounding area.
The privacy data omitted of the aircraft said he complied with mandatory service bulletins SB-001 rev-b and sb -001 rev c from stratus tool technologies.
Airworthiness directive 96-12-22 addresses Cessna aircraft company engine oil filter adapter assamblies installed on aircraft with contintental engine O-200 series, but not the O-300 series. We are submitting a safety recommendation that the contintinal engine O-300 series be added to the above-mentioned airworthiness directive.
