[Federal Register Volume 77, Number 35 (Wednesday, February 22, 2012)] [Rules and Regulations] [Pages 10352-10355] From the Federal Register Online via the Government Printing Office [www.gpo.gov] [FR Doc No: 2012-3973] –––––––––––––––––––––––––––––––––– DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2010-0956; Directorate Identifier 2010-NM-018-AD;Amendment 39-16951; AD 74-08-09 R3] RIN 2120-AA64 Airworthiness Directives; Various Transport Category Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. 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 thisunsafe condition on these products. DATES: This AD is effective March 28, 2012. Examining the AD Docket You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.
