new airworthiness directive (AD) for the products listed above.
This AD results from mandatory continuing airworthiness
information (MCAI) originated by an aviation authority ofanother
country to identify and correct an unsafe condition on an aviation
product. The MCAI originated by an aviation authority of another
country to identify and correct an unsafe conditionon an aviation
product. The MCAI describes the unsafe condition as: As a result of
a Wide Spread Fatigue Damage (WFD) calculation on A310 aircraft it
was found that a modification ofthe upper fuselage circumferential
joint at FR (frame) 55/58 is necessary to enable the aircraft to
reach the Extended Service Goal (ESG).
The unsafe condition is failure of the circumferentialpoint of
the upper fuselage, which could result in reduced structural
integrity of the airplane.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
