AD: Boeing

AD NUMBER: 2008-22-12
MANUFACTURER: Boeing
SUBJECT: Airworthiness Directive 2008-22-12
SUMMARY:
We are adopting a new airworthiness directive (AD) for all Boeing Model 727 airplanes.

This AD requires repetitive inspections for any crack in the area of the elevator side fitting/hinge fitting joint and for any crack or elongation inside and outside of the holes in the clevis and in the lug,corrective actions if necessary, and other specified actions.

This AD results from reports of elongated holes and cracks found in the lugs of the attachment fittings of the elevator quadrant upper support assembly at the tip of the vertical fin.

We are issuing this AD to detect and correct damage to the aft attachment lugs of the elevator quadrant support assembly that could lead to failure of the lugs. This condition could accelerate wear elsewhere in the elevator control system,which could reduce the crew's ability to maintain safe flight
