**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 this unsafe 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.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to revise AD 74–08–09 R2, Amendment 39–9680 (61 FR 32318, June 24, 1996). That AD applies to the specified products. The NPRM published in the Federal Register on October 6, 2010 (75 FR 61657). That NPRM proposed to continue to require 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 NPRM also proposed to extend the time an airplane may be operated with certain missing ashtrays.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (75 FR 61657, October 6, 2010) proposal and the FAA’s response to each comment. Support for the NPRM

Air Line Pilots Association, International (ALPA), Boeing, and Air Transport Association (ATA) supported the intent of the NPRM (75 FR 61657, October 6, 2010). Request to Credit MPD Task Cards

MNG Airlines reported that some airplane manufacturers’ maintenance planning documents (MPDs) include the requirements of AD 74–08–09 R2, Amendment 39–9680 (61 FR 32318, June 24, 1996), in a task card, which the operators add to their own MPDs for their fleet. The commenter requested that we revise the NPRM (75 FR 61657, October 6, 2010) by indicating that, if a manufacturer’s and operator’s MPDs cover a task card, the AD requirements are automatically satisfied.

We disagree with the request. Operators determine how to track the implementation and compliance of the AD requirements for their fleet. We do not consider it appropriate to include AD provisions that apply only to certain operators. It is not necessary to change the final rule to include this provision. Request To Clarify Relief Provisions

ATA recommended that we simplify and clarify the proposed relief provisions for airplanes having multiple lavatory doors. For those airplanes, ATA recommended that we revise the NPRM (75 FR 61657, October 6, 2010) to provide MMEL (Master Minimum Equipment List) relief for up to—and including—50 percent of the ashtrays for 10 days. (The NPRM specified only ‘‘up to’’ 50 percent of the ashtrays.) ATA noted that this recommendation would (1) Remove the proposed requirement to replace half of the missing ashtrays within 3 days; (2) provide a level of safety equal to or exceeding the level proposed for airplanes having only one


### 10353 Federal Register / Vol. 77, No. 35 / Wednesday, February 22, 2012 / Rules and Regulations

lavatory door; (3) simplify the management and oversight of MMEL relief by operators and FAA inspectors; and (4) clarify that the phrase ‘‘up to’’ includes 50 percent, which would eliminate differing interpretations.

We have reviewed the ATA proposal. While we agree that the proposal has merit, we find that it does not account for all possible scenarios. Paragraph (j) of the AD allows 3 days to install any ashtrays if more than 50 percent of the ashtrays are missing. The commenter’s proposed change, on the other hand, could ground airplanes: If, for example, 2 of 2 ashtrays are missing, 1 ash tray must be installed before further flight. We have therefore not changed the final rule regarding this issue. But, according to the provisions of paragraph (m) of this AD, we may approve requests to adjust the compliance schedule if the request includes data substantiating that the new schedule would provide an acceptable level of safety.
Request To Revise Compliance Time

Thomas Edward Young requested that we clarify paragraph (j) of the NPRM (75 FR 61657, October 6, 2010) to address the case of a single ashtray missing on an airplane with multiple lavatory door ashtrays. Mr. Young provided alternative text to address this situation.

We disagree with the request. Paragraph (j) of this AD adequately covers the scenario described by the commenter. We have not changed the final rule regarding this issue. Request To Clarify Proposed Changes ALPA requested clarification of the relief proposed in the NPRM (75 FR 61657, October 6, 2010) for two possible scenarios.

First, ALPA was concerned about possible confusion of the AD requirements for airplanes with an odd number of multiple lavatory doors with missing or inoperative ashtrays. In this case, the 50 percent criteria specified in the AD would result in a fractional number. ALPA therefore suggested that we revise the NPRM (75 FR 61657, October 6, 2010) to ensure that a fractional number of ashtrays be rounded to the next higher whole number.

Second, ALPA noted that, if there are groups of lavatories in multiple locations throughout an airplane, compliance with the proposed requirements aircraft-wide could result in all of the ashtrays in a group being missing or inoperative. To ensure that the required extinguishing capability is retained, ALPA therefore recommended an additional requirement to ensure that at least one lavatory door in each group of lavatories has a serviceable ashtray.

We disagree with the requests, although we considered both recommendations during the drafting of this revision of the AD. We determined that the commenter’s first recommendation (to address airplanes with an odd number of missing ashtrays) would have only added to the complexity of the AD. If the calculation of ashtrays needing to be replaced results in a fractional number, operators will need to round up this figure. The only way to replace 2.5 ashtrays, for example, is to replace 3 ashtrays. We find that additional clarification is not
necessary.

We determined that the commenter’s second recommendation (to address airplanes with all ashtrays missing in a group of lavatories) would have resulted in confusing and overly complicated requirements. The AD’s more simplified approach adequately addresses the unsafe condition.

We have not changed the AD regarding these issues.

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance

This action merely extends a certain compliance time and does not add any new additional economic burden on affected operators. The relief provided by this AD allows operators to continue to operate airplanes without the required number of ashtrays for a longer period of time than was previously permitted. This results in reduced costs to affected operators since it reduces the potential interruptions in service to reinstall the ashtrays. The current costs associated with this AD are provided below for the convenience of affected operators. The following table provides the estimated costs for U.S. operators to comply with this AD.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
Regulatory Findings

We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect 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.

For the reasons discussed above, I certify that this AD:

(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866,

(2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),

(3) Will not affect intrastate aviation in Alaska, and

(4) 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.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede airworthiness directive (AD) 2003–16– 18, amendment 39–13271 (68 FR 49344, August 18, 2003). That AD applies to the specified products. That SNPRM published in the Federal Register on November 7, 2011 (76 FR 68663). The original NPRM (75 FR 45560, August 3, 2010) proposed to revise the Trent 800 Time limits Manual (TLM) of the Trent 800 engine maintenance manuals (EMMs). The SNPRM proposed to prohibit installation of one certain critical part and to increase the life of another critical part whose lives were previously reduced by that existing AD.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM (76 FR 68663, November 7, 2011).

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance

Based on the service information, we estimate that this AD affects about 16 RB211–Trent 800 series turbofan engines of U.S. registry. The average labor rate is $85 per work-hour, but no labor cost is associated with this AD because discs are replaced at scheduled maintenance intervals. Prorated cost of parts cost about $45,000 per engine. Based on these figures, we estimate the cost of the AD on U.S. operators to be $720,000. Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701:
