  > Loss of engine power due to fuel contamination. Also causal was the ingestion of entrapped air that occurred during an abrupt maneuver and fuel-borne contamination that caused the fuel system check valves to leak, resulted in a lower than expected fuel level…
- [NTSB LAX97LA227](https://openairdocs.org/ntsb/LAX97LA227.md): Burkhart Grob G-103-TWIN II · Jacumba, CA · Accident · Minor injuries · Limited investigation · Final report · Jun 30, 1997 · N18AG · Substantial damage
