[Docket No. FAA-2017-0099; Directorate Identifier 2017-NE-02-AD]
RIN 2120-AA64

Airworthiness Directives; Siemens S.A.S. Smoke Detectors

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Siemens S.A.S. smoke detectors installed on various transport 
category airplanes. This proposed AD was prompted by a report that the 
affected smoke detectors failed an acceptance test. This proposed AD 
would require inspection and replacement of the affected smoke 
detectors. We are proposing this AD to correct the unsafe condition on 
these products.

DATES: We must receive comments on this NPRM by June 5, 2017.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2016-0024, dated January 26, 2016 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    During a maintenance operation, some smoke detectors P/N 
PMC1102-02 failed an acceptance test, due to a significant degraded 
optical sensitivity. Investigation results concluded that light-
emitting diodes (LED) were abnormally degraded, affecting specific 
batches where changes occurred in the LED manufacturer production 
process. Further investigation has determined that the affected LED 
have been installed on smoke detectors manufactured between November 
2010 and January 2013, and on certain repaired units.
    This condition, if not corrected, will generate an abnormal 
ageing of the smoke detector, leading to a decrease of the light 
intensity capability, possibly resulting in failure to detect smoke 
and consequent risk of an on-board uncontrolled fire.

    You may obtain further information by examining the MCAI in the AD 
docket on the Internet at http://www.regulations.gov by searching for 
and locating Docket No. FAA-2017-0099.

Related Service Information Under 1 CFR Part 51

    Siemens S.A.S. has issued Service Information Letter (SIL) No. PMC-
26-002, Revision No. 1, dated January 2016 and SIL No. PMC-26-003, 
Revision No. 2, dated February 2016. PMC 26-002 provides a list of 
serial numbers for affected smoke detectors, P/Ns PMC1102-02, PMC3100-
00, and GMC1102-02, known to be installed on Airbus A330 passenger, 
A330 freighter, and A380 airplanes. PMC 26-003 provides a list of 
serial numbers for affected smoke detectors, P/N PMC1102, known to be 
installed on Boeing B737-400 airplanes that have been converted via 
supplemental type certificate from a passenger to a freighter airplane. 
This service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of France, 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with the European Community, EASA has notified us 
of the unsafe condition described in the MCAI and service information 
referenced above. We are proposing this AD because we evaluated all

[[Page 18589]]

information provided by EASA and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design. This proposed AD would require inspection and replacement of 
the affected smoke detectors.

Costs of Compliance

    We estimate that this proposed AD affects an unknown number of 
smoke detectors installed on, but not limited to, various aircraft of 
U.S. registry.
    We estimate the following costs to comply with this proposed AD:

                                              $68.
----------------------------------------------------------------------------------------------------------------

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 determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 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),
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction, 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.

List of Subjects in 14 CFR Part 39

reference, Safety.
