[Federal Register Volume 59, Number 210 (Tuesday, November 1, 1994)] [Unknown Section] [Page 0] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 94-27052] [[Page Unknown]] [Federal Register: November 1, 1994] VOL. 59, NO. 210 Tuesday, November 1, 1994 DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. 94-NM-44-AD] Airworthiness Directives; Transport Category Airplanes AGENCY: Federal Aviation Administration, DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: This document proposes to revise an existing airworthiness directive (AD) that is applicable to all transport category airplanes. The existing 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. That action was prompted by fires occurring in lavatories, which were caused by, among other things, the improper disposal of smoking materials in lavatory waste receptacles. The actions specified by the AD are intended to prevent such fires. This action would provide for an alternative action regarding the current requirement to install specific placards at certain locations. DATES: Comments must be received by December 28, 1994. ADDRESSES: Submit comments in triplicate to the Federal Aviation Administration (FAA), Transport Airplane Directorate, ANM-103, Attention: Rules Docket No. 94-NM-44-AD, 1601 Lind Avenue, SW., Renton, Washington 98055-4056.

Discussion In 1974, the FAA issued AD 74-08-09, amendment 39-1917, which is applicable to all transport category airplanes having one or more lavatories equipped with paper or linen waste receptacles. That AD requires: 1. installation of placards on each side of each lavatory door over the door knob, containing wording to prohibit smoking in the lavatory; 2. installation of a placard on or near each lavatory paper or linen waste disposal receptacle door, containing wording to prohibit disposing of smoking materials in the waste receptacles; 3. establishment of a procedure to announce to airplane occupants that smoking is prohibited in the aircraft lavatories; 4. installation of ashtrays on or near the entry side of the lavatory doors; and 5. repetitive inspections of all lavatory paper and linen waste receptacle enclosure access doors and disposal doors for proper operation. That action was prompted by numerous incidents of fire that had occurred in the lavatory paper and linen waste receptacles of transport category airplanes, which were apparently caused by smoking materials deposited by passengers or crew in these receptacles. These fires can be a significant threat to the safety of persons on the airplane because of the emission of toxic smoke and the possibility of the fire progressing to critical components. The requirements of AD 74-08-09 are intended to prevent such fires. Subsequent to the issuance of that AD, certain required actions contained in it were added to part 25 of the Federal Aviation Regulations (FAR) (14 CFR part 25) (``Airworthiness Standards: Transport Category Airplanes'') by amendment 25-51 (issued March 6, 1980), making them applicable to all transport airplane designs certificated after the effective date of that amendment. Specifically, amendment 25-51 added a requirement to section 25.853 of the FAR (14 CFR 25.853) calling for the installation of ``No Smoking In Lavatory'' or ``No Smoking'' placards on both sides of the lavatory doors. Additionally, ``No Smoking'' symbology was permitted to be used on the placards in addition to the required wording. Amendment 25-72 (issued August 20, 1990) subsequently relocated these requirements to section 25.791 of the FAR (14 CFR 25.791) (``Passenger information signs and placards''). However, during the process, that amendment also incorporated the current FAA determinations that the lavatory door placards are acceptable if located ``on or adjacent to'' the lavatory doors [ref. section 25.791(d)]; and that appropriate ``No Smoking'' symbology may be used in lieu of wording specifying ``No Smoking,'' ``No Smoking in Lavatory,'' and ``No Cigarette Disposal'' [ref. section 25.791(e)]. Consequently, there now exists a difference between current type design philosophy and the requirements of AD 74-08-09. It has recently come to the FAA's attention that some aircraft certificated in accordance with section 25.791, amendment 25-72, and properly equipped with symbology-only placards installed adjacent to the lavatory doors, are being required to have worded placards added onto the door in accordance with AD 74-08-09 upon entering service. The FAA's intent in requiring installation of the ``No Smoking'' placards is to ensure that there is a visual reminder to passengers and other personnel onboard the airplane that smoking is prohibited in the lavatories. Whether this visual reminder is in the form or words or symbols is not necessarily a concern to the FAA, as long as the intent of the placards is clear and recognizable by the average person. The FAA considers that having airlines install worded placards in addition to their currently installed symbology placards represents an unnecessary cost burden to industry, with no added benefit to safety. Therefore, the FAA finds it is appropriate to revise AD 74-08-09 in order to make its requirements for placard installation consistent with those of part 25 of the FAR. Since an unsafe condition has been identified that is likely to exist or develop on other products of this same type design, the proposed AD would continue to require all of the same actions as currently required by AD 74-08-09. However, this action proposes to revise AD 74-08-09 to provide for an alternative action relative to the current requirement to install specific placards at specific locations. This proposal would permit operators to install the ``No Smoking'' placards in an area conspicuously located on or adjacent to each side of the lavatory door. In addition, in lieu of the currently required specified wording for required placards, this action proposes to permit the use of symbols that clearly express the intent of the placard. Since this proposed action only provides for an alternative method of complying with an existing rule, it does not add any new additional economic burden on affected operators. The current costs associated with this amendment are reiterated below for the convenience of affected operators: The costs associated with the currently required placard installations entail approximately 1 work hour per airplane, at an average labor rate of $60 per work hour. The cost of required parts is negligible. Based on these figures, the total cost impact of the installation requirements of the AD on U.S. operators is estimated to be $60 per airplane. The costs associated with the currently required inspections entail approximately 1.5 work hours per airplane per inspection, at an average labor rate of $60 per work hour. Based on these figures, the total cost impact of the inspection requirements of this AD on U.S. operators is estimated to be $90 per airplane per inspection. The regulations proposed herein would not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. Therefore, in accordance with Executive Order 12612, it is determined that this proposal would not have sufficient federalism implications to warrant the preparation of a Federalism Assessment. For the reasons discussed above, I certify that this proposed regulation (1) is not a ``significant regulatory action'' under Executive Order 12866; (2) is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated, will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
