31.4.3.6 Calibration Procedure E: Engine Run-Up Vibration Test
NOTE
Calibration Procedure E is required for all installations to validate the vibration
characteristics of the installation. Calibration Procedures B through D are not required
prior to this procedure.
NOTE
Passing the Engine Run-Up Vibration test does not remove the requirement to rigidly
mount the GSU 25/GSU 73 to the aircraft primary structure. The Engine Run-Up
Vibration Test is intended to help discover mounting issues but successful completion of
the test does not validate the mounting of the GSU and GMU, and does not account for all
possible vibration profiles that may be encountered during normal aircraft operation
