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:
Several cases have been reported of in-flight loss of the drive strut fitting from the movable fairing of flap track No. 3. Consequently, the flap track No. 3 fairing was detached from its aft end, and found hanging. Investigations have shown that the detachment of the aft lower drive strut fitting from the fairing occurred due to the four bonded inserts being pulled out. This condition, if not corrected, could lead to in-flight loss of the affected aircraft parts, potentially resulting in injuries to persons on the ground.
* * * * * The proposed AD would require actions that are intended to address the unsafe condition described inthe MCAI.
