Action
Final rule.
Summary
We are revising an existing airworthiness directive (AD) for transport category airplanes that have one or more lavatories equipped with paper or linen waste receptacles. That AD currently requires installation of placards prohibiting smoking in the lavatory and disposal of cigarettes in the lavatory waste receptacles; establishment of a procedure to announce to airplane occupants that smoking is prohibited in the lavatories; installation of ashtrays at certain locations; and repetitive inspections to ensure that lavatory waste receptacle doors operate correctly. This new AD extends the time an airplane may be operated with certain missing ashtrays. This AD was prompted by the determination that certain compliance times required by the existing AD could be extended and still address fires occurring in lavatories caused by, among other things, the improper disposal of smoking materials in lavatory waste receptacles. We are issuing this AD to correct this unsafe condition on these products.
