Required Actions
Visually inspect the four engine exhaust pipe ejector attachment lugs, starter-generator attachment flange, and attachment half-clamps for cracks. Measure each starter-generator engine clamp torque and vibration level. Record the starter-generator vibration level on a component history card or equivalent record. If the starter-generator vibration level is equal to or higher than 0.5 inches per second (IPS), repair or replace the starter-generator as necessary.
