## 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:

One A300-600 aeroplane operator reported that, during a routine inspection, the Right Hand frame 40 forward fitting between stringer 32 and stringer 33 was found cracked. The subject aeroplane had previously been modified in accordance with Airbus SB A300-57-6053 (Airbus Modification 10453).

This condition, if not corrected, could result in a deterioration of the structural integrity of the frame.

* * * * *

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
