FN FAL said:I test flew a 414 after an engine swap and an A&P accompanied me on the flight. We did the best pre-flight you could do and needless to say, we developed an un-known engine roughness problem on the new engine and landed.
The mechanic exited the plane while I secured the cockpit and all I could hear was cussing, the sound of the cowling hitting the tarmac, more cussing followed by the sound of footsteps and then the crash of someone's tool box being tipped over. Followed by more yelling.
When I got out of the plane, I saw a puddle under the engine, at least 6 foot square. The new engine and turbo housing was stained avgas blue in color, and smelled like avagas.
In the end, it was the fuel lines coming out of the Bendix unit that were finger tight only and had come lose in flight and were spraying that engine and turbo charger with fuel. There's no way I would have caught that one on the pre-flight and you'd be lying if you said you would have either.
Had we exploded on that flight, would the mechanic who signed off on the engine be criminally charged with negligent homicide? Could be...maybe...possibly? That law is on the books in our state...and most likely in your's as well. I just depends on whether or not your local prosecutor is going to push it in such a case.
Buddy of mine had a similar situation. In this case it was a oil line that wasn't tightened, and it didn't go quite as well. They were at about 10,000 ft on a test flight when one engine caught fire. They were able to put it down on a gravel bar and both walked away, so I guess it was a good landing.
