Unsafe Condition
Lack of cold expansion of an existing drain hole in bottom skin panel 3 (located aft of the rear spar) could lead to cracks initiating from the drain hole. Additionally, the incorrect location of the drain hole traps moisture, resulting in corrosion and reduced structural integrity of the wings.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the drain hole for cracks using high frequency eddy current (HFEC) rototest inspection. Cold expand the existing drain hole and drill/ream it to a specific diameter. Add another drain hole if necessary, drilling and reaming it to a specific diameter and cold expanding it.
