On March 14, 1985, a Cessna 305A (registration N5291G) was involved in an aviation accident near Sugar Loaf Key, FL. Investigators recorded the probable cause as: Insufficient fuel flow due to a contaminated micron fuel filter, which resulted in engine failure during sustained takeoff power. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An aircraft experienced engine failure shortly after takeoff because a micron fuel filter was heavily contaminated, restricting fuel flow and causing the engine to stop at sustained takeoff power.
What happened
The engine failed just after takeoff. The aircraft landed in a field north of the airport, collided with trees, and nosed over.
The investigation
Post-accident examination of the fuel system showed that the micron fuel filter was contaminated to the extent that it caused insufficient fuel flow, resulting in the engine failure at the sustained takeoff power setting.
Probable cause
Insufficient fuel flow due to a contaminated micron fuel filter, which resulted in engine failure during sustained takeoff power.
