Airworthiness Directives; Airbus Model A380-800 Series Airplanes


AGENCY:
 
Federal Aviation Administration (FAA), Department of Transportation (DOT).


ACTION:
 
Final rule; request for comments.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
We are adopting a new airworthiness directive (AD) for the products listed above. This


AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation


authority of another country to identify and correct an unsafe condition on an aviation product. The


MCAI describes the unsafe condition as:


A crack has been found on the Droop Nose (DN) 1 master sidestay bracket on the


inboard leading edge of an Airbus A380 flight test aeroplane.


In case of failure of the master bracket, the sub-master bracket would be able to


sustain limit loads but not ultimate loads.


This condition, if not detected and corrected, could lead to a DN failure which would


affect the structural integrity of that wing area.

This AD requires actions that are intended to address the unsafe condition described in the MCAI.


DATES:
 
This AD becomes effective September 2, 2010.


The Director of the Federal Register approved the incorporation by reference of a certain


publication listed in the AD as of September 2, 2010.


We must receive comments on this AD by October 4, 2010.

SUPPLEMENTARY INFORMATION:


Discussion


The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member


States of the European Community, has issued EASA Airworthiness Directive 2009-0213, dated


October 8, 2009 (referred to after this as ''the MCAI''), to correct an unsafe condition for the specified


products. The MCAI states:


A crack has been found on the Droop Nose (DN) 1 master sidestay bracket on the


inboard leading edge of an Airbus A380 flight test aeroplane.


In case of failure of the master bracket, the sub-master bracket would be able to


sustain limit loads but not ultimate loads.


This condition, if not detected and corrected, could lead to a DN failure which would


affect the structural integrity of that wing area.


This AD requires an inspection programme to detect any crack in the DN 1 master


sidestay bracket and subsequently in the sub-master bracket, and the accomplishment


of the associated corrective actions, as applicable.


Corrective actions include replacing the cracked DN 1 master sidestay bracket, performing a detailed


visual inspection for cracks of the associated DN 1 sub-master sidestay bracket, and contacting


Airbus if cracks are found on the DN 1 sub-master sidestay bracket. You may obtain further


information by examining the MCAI in the AD docket.


Relevant Service Information


Airbus has issued Mandatory Service Bulletin A380-57-8019, dated August 5, 2009. The actions


described in this service information are intended to correct the unsafe condition identified in the


MCAI.
