## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A310-200 and -300 series airplanes. This AD requires doing repetitive rotating probe inspections for any crack of the rear spar internal angle and the left and right sides of the tee fitting, and doing related investigative/corrective actions if necessary. This AD also requires modifying the holes in the internal angle and tee fitting by cold expansion. This AD results from full-scale fatigue tests, which revealed cracks in the lower rear spar internal angle, and tee fitting. We are issuing this AD to detect and correct fatigue cracks of the rear spar internal angle and tee fitting, which could lead to the rupture of the internal angle, tee fitting, and rear spar, and consequent reduced structural integrity of the wings.
