## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A300 airplanes. This proposed AD would require modifying the airplane and the engine/nacelle to install a third line of defense against inadvertent deployment of the thrust reverser in flight. This proposed AD would also require two other actions that must be accomplished before or concurrently with the modification: installing a structural change in the fan cowl to avoid interference; and installing a dedicated, shielded electrical circuit. This proposed AD results from a report that the manufacturer has developed a third line of defense against the inadvertent deployment of the thrust reverser of A300 airplanes that are equipped with General Electric CF6- 50 series engines (in accordance with FAA guidelines). We are proposing this AD to prevent inadvertent deployment of the thrust reverser in flight, which could result in reduced controllability of the airplane.
