AD NUMBER: 2011-04-06

MANUFACTURER: Airbus Model A340-200, -300, -500, and -600 Series Airplanes
SUBJECT: Airworthiness Directive 2011-04-06

SUMMARY: 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:
The airworthiness limitations applicable to Damage Tolerant Airworthiness Limitation Items (DT ALI) are currently given in Airbus A340 ALI Document reference AI/SE-M4/95A.0051/97, which is approved by the European Aviation Safety Agency (EASA) and referenced in Airbus Airworthiness Limitations Section (ALS) Part 2.

The issue 11 of Airbus A340 ALI Document introduces more restrictive maintenance requirements/airworthiness limitations. Failure to comply with this issue 11 constitutes an unsafe condition.

This new [EASA] AD retains the requirements of EASA AD 2007-0158, which is superseded, and requires the implementation of the more restrictive maintenance requirements/airworthiness limitations as specified in Airbus A340 ALI Document AI/SE-M4/95A.0051/97 issue 11.

The unsafe condition is fatigue cracking, damage, and corrosion in certain structure, which could result in reduced structural integrity of the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
