## Latest cases

- [NTSB CEN26LA281](https://openairdocs.org/ntsb/CEN26LA281.md): Mooney M20E · Longmont, CO · Accident · No injuries · Class 4 · Limited · Investigation open · Aug 4, 2026 · N3264F · Substantial damage
- [NTSB CEN22LA255](https://openairdocs.org/ntsb/CEN22LA255.md): Mooney M20E · Stillwater, OK · Accident · No injuries · Class 3 · Limited · Final report · Jun 18, 2022 · N5895Q · Substantial damage
  > The inadequate maintenance and inspection of the engine induction air coupling, which impeded airflow to the engine and resulted in the subsequent partial loss of engine power.
- [NTSB GAA18CA059](https://openairdocs.org/ntsb/GAA18CA059.md): Mooney M20 · Tucson, AZ · Accident · No injuries · Data collection · Final report · Nov 26, 2017 · N6002Q · Substantial damage
  > The pilot’s inadequate preflight and in-flight fuel management, which resulted in an intermittent loss of engine power due to fuel starvation.
- [NTSB WPR16LA039](https://openairdocs.org/ntsb/WPR16LA039.md): Mooney M20E · Corona, CA · Accident · No injuries · Limited investigation · Final report · Dec 14, 2015 · N5863Q · Substantial damage
  > A partial loss of engine power during initial climb for reasons that could not be determined based on available information. Contributing to the accident was the pilot’s decision to conduct the takeoff with observed engine deficiencies.
- [NTSB ERA16LA046](https://openairdocs.org/ntsb/ERA16LA046.md): Mooney M20 · Fort Meade, MD · Accident · No injuries · Limited investigation · Final report · Nov 22, 2015 · N5512Q · Substantial damage
  > A partial loss of engine power for reasons that could not be determined because postaccident examination of the engine revealed no mechanical malfunctions or failures that would have precluded normal operation.
- [NTSB CEN13LA095](https://openairdocs.org/ntsb/CEN13LA095.md): Mooney M20E · Gurdon, AR · Accident · No injuries · Limited investigation · Final report · Dec 5, 2012 · N9493V · Substantial damage
