AIRWORTHINESS DIRECTIVE
AD No.: 2014-0177
Date: 25 July 2014
Fuselage – Rear Fuselage Clips, Shear Webs and Angles –
Replacement
During the A320 fatigue test campaign for Extended Service Goal (ESG), it was determined that fatigue damage could appear on the clips, shear webs and angles at rear fuselage section 19, on Frame (FR) 72 and FR74.
This condition, if not detected and corrected, could affect the structural integrity of the aeroplane.
To address this potential unsafe condition, Airbus developed a modification,
which has been published through Airbus Service Bulletin (SB) A320-53-1266 for in-service application to allow aeroplanes to operate up to the new ESG limit.
For the reasons described above, this AD requires replacement of the affected clips, shear webs and angles at rear fuselage section 19, FR72 and FR74.
