ACTION: Final rule. wwhite on PROD1PC61 with RULES AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain smoke detectors installed on various transport category airplanes. This AD requires replacing the affected smoke detectors with modified smoke detectors. This AD results from a report indicating that the affected smoke detectors can ‘‘lock up’’ during electrical power transfer from the auxiliary power unit to the engines. We are issuing this AD to identify and provide corrective action for a potentially inoperative smoke detector and to ensure that the flightcrew is alerted in the event of a fire. DATES: This AD becomes effective March 24, 2006. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of March 24, 2006.

SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the airworthiness directive (AD) docket on the Internet at https://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section. Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain smoke detectors installed on various transport category airplanes. That NPRM was published in the Federal Register on August 8, 2005 (70 FR 45585). That NPRM proposed to require replacing the affected smoke detectors with modified smoke detectors. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments on the proposed AD. Request To Revise Applicability and Compliance Time The commenter, on behalf of an airline, requests that we revise the applicability of the proposed AD to specify McDonnell Douglas Model 717– 200 airplanes. He notes that Meggitt Model 602 smoke detectors are installed on these airplanes as part of the type design. He recognizes that, in this case, the applicability is not limited to the airplane models listed in Table 1 of the proposed AD. But he feels that airplanes known to be equipped with the affected smoke detectors should be specifically identified in the applicability. He notes that Meggitt Service Information Letter (SIL) 8930–26–01 (cited in the proposed AD) specifies that replacing the smoke detectors on Model 717–200 airplanes could take up to 18 months. He requests that we either PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 extend the compliance time accordingly or obtain Meggitt’s written confirmation that all operators can meet the proposed 6-month compliance time. FAA Response Since affected Model 602 smoke detectors are installed in Model 717– 200 airplanes and the AD applies to smoke detectors installed on transport category airplanes ‘‘including but not limited to’’ the airplane models listed in Table 1, this AD applies to Model 717– 200 airplanes. But the smoke detector lock-up condition depends on certain design characteristics of the airplane’s electrical system. Testing has demonstrated that the Model 717–200 electrical power transfer characteristics do not cause the smoke detector to lock up. So there is no immediate concern for the safety of flight of Model 717–200 airplanes due to the identified unsafe condition. Despite this finding, however, we require that all affected smoke detectors be replaced because these interchangeable parts may later be installed on airplanes with the demonstrated unsafe condition. Meggitt has confirmed that a six-month compliance time is feasible, since a significant number of affected smoke detectors have already been modified. But under the provisions of paragraph (i) of this final rule, operators may request an adjustment of the compliance time if they provide data proving that the new compliance time would ensure an acceptable level of safety. We have not changed the final rule regarding these issues. Revised Service Information Meggit has revised SIL 8930–26–01 according to the following schedule. SIL REVISION HISTORY Version Original issue ............ Revision A ................ Revision B ................ Revision C ................ Date November 8, 2004. November 8, 2004. January 19, 2005. May 25, 2005. The SIL was revised to, among other things, correct an incorrect smoke detector part number; the remaining information in the SIL is essentially the same. We have revised paragraph (f) in this final rule to refer to specific revisions of the SIL. Clarification of Alternative Method of Compliance (AMOC) Paragraph We have revised this action to clarify the appropriate procedure for notifying the principal inspector before using any E:\FR\FM\17FER1.SGM 17FER1 Federal Register / Vol. 71, No. 33 / Friday, February 17, 2006 / Rules and Regulations approved AMOC on any airplane to which the AMOC applies. Conclusion We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance It takes about 1 work hour per airplane, at an average hourly labor rate of $65, to replace a smoke detector installed on the airplane. Replacement parts will be provided at no cost to the operators. We have been advised that about 4,637 smoke detectors have already been replaced. We estimate that affected smoke detectors are installed on 318 U.S.-registered airplanes. There may be as many as 28 affected smoke detectors on an airplane. This AD could cost as much as $1,820 per airplane. 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); and (3) 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain smoke detectors installed on various transport category 
airplanes. This AD requires replacing the affected smoke detectors with 
modified smoke detectors. This AD results from a report indicating that 
the affected smoke detectors can ``lock up'' during electrical power 
transfer from the auxiliary power unit to the engines. We are issuing 
this AD to identify and provide corrective action for a potentially 
inoperative smoke detector and to ensure that the flightcrew is alerted 
in the event of a fire.

DATES: This AD becomes effective March 24, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of March 24, 
2006.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at https://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain smoke 
detectors installed on various transport category airplanes. That NPRM 
was published in the Federal Register on August 8, 2005 (70 FR 45585). 
That NPRM proposed to require replacing the affected smoke detectors 
with modified smoke detectors.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments on the proposed 
AD.

Request To Revise Applicability and Compliance Time

    The commenter, on behalf of an airline, requests that we revise the 
applicability of the proposed AD to specify McDonnell Douglas Model 
717-200 airplanes. He notes that Meggitt Model 602 smoke detectors are 
installed on these airplanes as part of the type design. He recognizes 
that, in this case, the applicability is not limited to the airplane 
models listed in Table 1 of the proposed AD. But he feels that 
airplanes known to be equipped with the affected smoke detectors should 
be specifically identified in the applicability.
    He notes that Meggitt Service Information Letter (SIL) 8930-26-01 
(cited in the proposed AD) specifies that replacing the smoke detectors 
on Model 717-200 airplanes could take up to 18 months. He requests that 
we either extend the compliance time accordingly or obtain Meggitt's 
written confirmation that all operators can meet the proposed 6-month 
compliance time.

FAA Response

    Since affected Model 602 smoke detectors are installed in Model 
717-200 airplanes and the AD applies to smoke detectors installed on 
transport category airplanes ``including but not limited to'' the 
airplane models listed in Table 1, this AD applies to Model 717-200 
airplanes. But the smoke detector lock-up condition depends on certain 
design characteristics of the airplane's electrical system. Testing has 
demonstrated that the Model 717-200 electrical power transfer 
characteristics do not cause the smoke detector to lock up. So there is 
no immediate concern for the safety of flight of Model 717-200 
airplanes due to the identified unsafe condition.
    Despite this finding, however, we require that all affected smoke 
detectors be replaced because these interchangeable parts may later be 
installed on airplanes with the demonstrated unsafe condition. Meggitt 
has confirmed that a six-month compliance time is feasible, since a 
significant number of affected smoke detectors have already been 
modified. But under the provisions of paragraph (i) of this final rule, 
operators may request an adjustment of the compliance time if they 
provide data proving that the new compliance time would ensure an 
acceptable level of safety.
    We have not changed the final rule regarding these issues.

Revised Service Information

    Meggit has revised SIL 8930-26-01 according to the following 
schedule.

Revision A..........................  November 8, 2004.
Revision B..........................  January 19, 2005.
Revision C..........................  May 25, 2005.
------------------------------------------------------------------------

    The SIL was revised to, among other things, correct an incorrect 
smoke detector part number; the remaining information in the SIL is 
essentially the same. We have revised paragraph (f) in this final rule 
to refer to specific revisions of the SIL.

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any

[[Page 8447]]

approved AMOC on any airplane to which the AMOC applies.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, and determined that air safety and the public 
interest require adopting the AD with the changes described previously. 
We have determined that these changes will neither increase the 
economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    It takes about 1 work hour per airplane, at an average hourly labor 
rate of $65, to replace a smoke detector installed on the airplane. 
Replacement parts will be provided at no cost to the operators. We have 
been advised that about 4,637 smoke detectors have already been 
replaced. We estimate that affected smoke detectors are installed on 
318 U.S.-registered airplanes. There may be as many as 28 affected 
smoke detectors on an airplane. This AD could cost as much as $1,820 
per airplane.

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); and
    (3) 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.
    We prepared a regulatory evaluation of the estimated costs to
