Airworthiness Directive · Amendment 39-10927 · McDonnell Douglas Model MD-90-30 Series Airplanes
McDonnell Douglas Model MD-90-30 Series Airplanes
Model MD-90-30 series airplanes; as listed in paragraph 1.A.1. of McDonnell Douglas Alert Service Bulletin MD90- 25A017, Revision R01, dated October 16, 1997, McDonnell Douglas Service Bulletin MD90-25-022, Revision R01, dated October 15, 1997, and McDonnell Douglas Service Bulletin MD90-25A023, Revision R01, dated October 15, 1997; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-90-30 series airplanes, that requires repetitive inspections to detect debris in the areas behind the aft lavatory toilet shroud, behind the aft lavatory modules, and below the cabin floor aft of the aft cargo compartment bulkhead; and removal of debris. This amendment also requires modification of the lavatory toilet shroud assemblies and modification of the lavatory entry door louvers, which terminates the repetitive inspections. This amendment is prompted by reports of paper debris collecting below the cabin floor. The actions specified by this AD are intended to prevent paper debris from collecting below the cabin floor, which could result in a potential fire hazard or possible loss of elevator control system redundancy.
