Summary
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes), and Model A310 series airplanes. This proposed AD was prompted by reports of insufficient clearance for the electrical wiring bundles in the leading and trailing edges of the left and right wings. This proposed AD would require installation of new bracket assemblies to ensure adequate clearance between the wiring and the structure, and installation of protective split sleeves as mechanical protection to the electrical harnesses. We are proposing this AD to detect and correct insufficient clearance of electrical wiring bundles located in the leading and trailing edges of the left and right wings, which could lead to chafing damage and arcing, possibly resulting in an on-board fire.
