## Latest cases

- [NTSB LAX91LA033](https://openairdocs.org/ntsb/LAX91LA033.md): Mooney M20E · Tuba City, AZ · Accident · Minor injuries · Limited investigation · Final report · Nov 17, 1990 · N5703Q · Substantial damage
  > Failure of the piston rings which reduced the available engine power, and the pilot's continued operation of his airplane with a known engine deficiency during the relatively high density altitude conditions.
- [NTSB CHI90LA276](https://openairdocs.org/ntsb/CHI90LA276.md): Mooney M20E · Morrison, IL · Accident · No injuries · Limited investigation · Final report · Sep 27, 1990 · N7197U · Substantial damage
  > Improper maintenance of the propeller blade by unknown persons and the subsequent failure of the blade in fatigue during cruise flight. A factor was: unsuitable terrain.
- [NTSB SEA90LA175](https://openairdocs.org/ntsb/SEA90LA175.md): Mooney M-20E · Cheyenne, WY · Accident · No injuries · Limited investigation · Final report · Sep 5, 1990 · N9067V · Substantial damage
  > Pilot's failure to extend the landing gear prior to landing after having been distracted by traffic. A mitigating factor in this accident was the fact that the gear warning horn did not function.
- [NTSB FTW90LA128](https://openairdocs.org/ntsb/FTW90LA128.md): Mooney M-20E · Luling, TX · Accident · No injuries · Limited investigation · Final report · Jun 29, 1990 · N9376V · Substantial damage
  > Loss of control in-flight due to the pilot's failure to maintain adequate airspeed. Factors would be the high density altitude and the tree that he hit.
- [NTSB BFO90FA057](https://openairdocs.org/ntsb/BFO90FA057.md): Mooney M20E · Charleston, WV · Accident · 2 fatal · Field investigation · Final report · Jun 15, 1990 · N3260F · Destroyed
  > The pilot's improper IFR procedures, his failure to maintain a proper glide path on the ILS approach, and his failure to initiate a missed approach at the decision height. The adverse weather was a related factor.
- [NTSB LAX90LA165](https://openairdocs.org/ntsb/LAX90LA165.md): Mooney M20 · Torrance, CA · Accident · No injuries · Limited investigation · Final report · May 6, 1990 · N300MD · Substantial damage
  > Water contamination introduced into the airplane fuel system when the airplane was washed. Contributing to the accident was an 18 knot tailwind during landing roll which resulted in the airplane overrunning the runway.
- [NTSB MIA90WA068](https://openairdocs.org/ntsb/MIA90WA068.md): Mooney M20F · San Andros, Bahamas · Accident · 5 fatal · Foreign investigation · Feb 7, 1990 · N9370M · Destroyed
