Airworthiness Directive · Amendment 39-12782 · McDonnell Douglas Model MD-90-30 Airplanes
McDonnell Douglas Model MD-90-30 Airplanes
Model MD-90-30 airplanes, certificated in any category; as identified in Boeing Service Bulletin MD90-24-007, Revision 02, dated July 16, 2001.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-90-30 airplanes, that requires installation of two arcing protection brackets below and behind the circuit breakers located in the generator control rack in the electrical/electronics compartment. The actions specified by this AD are intended to prevent arcing between circuit breaker terminals and adjacent equipment and structure located in the generator control rack in the electrical/electronics compartment, which, if not corrected, could result in possible electrical shock to maintenance personnel during maintenance operations. This action is intended to address the identified unsafe condition.
