## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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:

As a result of a Wide Spread Fatigue Damage (WFD) calculation on A310 aircraft it was found that a modification of the 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 circumferential joint of the upper fuselage, which could result in reduced structural integrity of the airplane. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
