Here's a little info just to clear a couple of things.
The S-92 has two fuel prime pumps for APU run and engine starting.
ASB 92-18-001 revA allows the removal of one force generator and the continued operation with the remaining two force generators. The force generator mechanical units that have the cracks in the mounting area are located in the right hand cabin wall, about a foot from the floor. It did not drive itself through the roof, some wiring and, eventually, the top of the fuel tank.
