Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A310 series airplanes. This proposal would require repetitive inspections to detect cracked or broken support brackets of the upper wing-to-fuselage fairings, and replacement of any discrepant support brackets with new brackets. This proposal also would require replacement of the fairing seals with new, improved seals; modification of the fairing panels; and installation of new bulkheads; which would constitute terminating action for the repetitive inspections. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent reduced structural integrity of the fairing support brackets, which could result in loss of the wing-to-fuselage fairings during flight, and consequent structural damage to the airplane.
