Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This proposed AD would require replacing the existing halogen lamps in the cargo compartment light assemblies with new incandescent lamps, and installing warning and identification placards. This proposed AD is prompted by a report of an aft cargo fire during flight. We are proposing this AD to prevent a fire in the cargo compartment.
