1.A line tech tells you he may have put Jet A into a piston aircraft. What do you do first?
Why they ask
Misfueling is one of the scariest things that can happen at an FBO. They want to see you stop the aircraft first and think about liability second.
How to answer
- Stop the aircraft from flying: reach the pilot directly and tag the aircraft
- Quarantine the truck and pull the fuel ticket and training record
- Bring in maintenance to drain and inspect before anyone starts the engine
- Notify the owner, insurer and, where required, the right authorities
- Afterward, fix the process with grade-specific nozzles, decals or a second person checking the grade
