Background:

The FAA received reports of elongated holes and cracks in the lugs of the attachment fittings of the elevator quadrant upper support assembly at the tip of the vertical fin.  Undetected damage to the aft attachment lugs of the elevator quadrant support assembly could lead to failure of the lugs, which could accelerate wear elsewhere in the elevator control system and reduce the crew’s ability to maintain safe flight.
