>>Depends on the nature of the engine problem. A catastrophic failure can bring down an aircraft with ease.
An engine failure won't disintegrate an aircraft, will it?
Depends on the aircraft and the nature and setting of the failure.
I've seen an catastrophic failure destroy an F-16 on the ground by virtue of the fire that followed the failure. That was in Turkey.
Also, you have to consider what damage the failure might cause to the aircraft and what follow-on damage might occur. An engine failure is what brought down the DC-10 over Sioux City back in 1989. The fan-disk came apart and destroyed the hydraulics system on the jet. If the crew hadn't possessed the skill they had, there likely wouldn't have been any survivors.

The engine failure itself might not cause the destruction of the aircraft - the follow-on damage could.
