Airworthiness Directives; The Boeing Company Model 767-200 and -300 Series Airplanes

概要

We propose to adopt a new airworthiness directive (AD) for certain Model 767-200 and 767-300 series airplanes. This proposed AD would require installing cargo bulkhead supports, ceiling supports, secondary dam support, drainage tubing, and ceiling panels to the forward lower lobe in the forward cargo compartment. This proposed AD was prompted by reports of water accumulation in the forward lower lobe of the forward cargo compartment. We are proposing this AD to prevent water from accumulating in the forward lower lobe of the forward cargo compartment and entering the adjacent electronic equipment bay, which could result in an electrical short and the potential loss of several functions essential for safe flight.
