## Latest cases

- [NTSB DFW06LA154](https://openairdocs.org/ntsb/DFW06LA154.md): McClung Christian Eagle I · Pocahontas, AR · Accident · No injuries · Limited investigation · Final report · Jun 6, 2006 · N181DM · Substantial damage
  > The loss of engine power as a result of a fractured crankshaft due to fatigue. A factor was the engine modifications to increase engine horsepower.
- [NTSB LAX04LA039](https://openairdocs.org/ntsb/LAX04LA039.md): Zivko Edge 540-T · King City, CA · Accident · Serious injuries · Limited investigation · Final report · Nov 11, 2003 · N540RC · Substantial damage
  > The after market manufacturer's improper application of a crankshaft, which exceeded the original manufacturer's intended use. A factor in the accident was the oil covering the windscreen, which restricted the pilot's ability to see.
- [NTSB LAX99LA103](https://openairdocs.org/ntsb/LAX99LA103.md): Zivko Aeronautics Edge 540 · Livermore, CA · Accident · No injuries · Limited investigation · Final report · Feb 19, 1999 · N9ND · Substantial damage
  > The manufacturer's inadequate quality control procedures, which allowed an improperly manufactured crankshaft to be shipped, resulting in the separation of one counterweight from the crankshaft lug and the subsequent catastrophic internal failure of the…
- [NTSB SEA95LA056](https://openairdocs.org/ntsb/SEA95LA056.md): Pitts S-2B · Spokane, WA · Accident · No injuries · Limited investigation · Final report · Feb 25, 1995 · N49335 · Substantial damage
  > Fatigue failure of the crankshaft. Factors were the soft terrain and the pilot/owner's failure to conduct recurring crankshaft inspections recommended by the manufacturer.
- [NTSB FTW89LA048](https://openairdocs.org/ntsb/FTW89LA048.md): Pitts S2B · Walker, LA · Accident · Serious injuries · Limited investigation · Final report · Feb 11, 1989 · N11SE · Destroyed
  > Loss of total engine power due to fuel exhaustion. Fuel exhaustion occurred due to the pilot's failure to perform fuel consumption calculations. Contributing was the inadequate fuel quanity sight gauge in the rear cockpit, which was occupied by the PIC.
