Crashed a helicopter.
Ran an airplane off the runway.
Now crashed after engine failure.
Engine failure (mechanical) in aircraft is so rare these days as to be non existent.
Any engine failure nowadays is almost certainly pilot induced.
Most likely it is fuel starvation.
That can happen when a fuel selector is improperly employed.
Or it can happen when the mixture is set improperly.
There are also a number of ways to abuse the engine into quitting.
Not the least of which is a loose or missing oil drain plug.
Or the improper setting of an oil related lever.
