            Figure 3, a number was omitted from the table heading.  In all
            other respects, the original document remains the same.

    This AD  was prompted  by a  report that  the affected smoke detectors
    failed an acceptance test.  We are issuing this AD to  prevent failure
    of the smoke detector,  on-board uncontrolled fire,  and damage to the
    airplane.

(f) COMPLIANCE

    Siemens smoke detector,  or review your maintenance records, to deter-
    mine if an affected detector is installed.

(2) For smoke detectors identified in paragraph (c)(1) of this AD, replace
    the detectors within the compliance times specified  in  Figures 2, 3,
    and 4 to paragraph (f) of this AD.

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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

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

DATES: This AD becomes effective October 31, 2017.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of October 31,
2017.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to the specified products. The
NPRM was published in the Federal Register on April 20, 2017 (82 FR
18588). The NPRM proposed 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.

Comments

We gave the public the opportunity to participate in developing
this AD. We considered the comments received.

Comment on Certifying Authority

The European Aviation Safety Agency (EASA) commented that the
affected smoke detectors were approved by EASA rather than by France.
We agree. These smoke detectors were approved by EASA. We did not
change this AD because this AD does not reference the certifying
authority for these smoke detectors. The section commented on by EASA
exists only in the ``Determination and Requirements of This Proposed
AD'' section of the NPRM. We did not change this AD.

Request To Revise Applicability

Delta Air Lines (Delta) requested that we revise the Applicability
section of this AD to remove the reference to the date range when
certain affected smoke detectors were produced. Delta indicated that
the NPRM may be interpreted as implying that there are more affected
smoke detector serial numbers than those identified in paragraph 1/D/of
Siemens Service Information Letter (SIL) PMC-26-002, Revision No. 1,
dated January 2016, and of SIL PMC-26-003, Revision No. 2, dated
February, 2016. Delta commented that removing the date range from the
Applicability section of this AD would clarify applicability for
operators.
We agree. We find that providing the part numbers (P/Ns) and serial
numbers (S/Ns) for the affected smoke detectors sufficiently identifies
all affected detectors. We revised this AD by removing the reference to
the production date range from the Applicability section of this AD.

Request To Revise Compliance Schedule

Delta requested that we revise paragraph (f)(2) in the compliance
section of this AD to indicate that repaired units identified in Figure
(1) to paragraph (c) of this AD should be replaced within 5 months
after the effective date of this AD. Delta commented that the NPRM does
not specify when these affected detectors are to be replaced.
We agree. We revised the compliance section of this AD to specify
that smoke detectors identified in paragraph (c)(2) of this AD must be
replaced within 5 months after the effective date of this AD.

Support for This AD

The Air Line Pilots Association, International, commented that it
supports the intent of this AD to correct the unsafe condition on the
affected products.

Conclusion

We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously. We determined that these
changes will not increase the economic burden on any operator or
increase the scope of this AD.

Related Service Information Under 1 CFR Part 51


Siemens has issued SIL No. PMC-26-002, Revision No. 1, dated
January 2016 and SIL No. PMC-26-003, Revision No. 2, dated February
2016. SIL No. PMC 26-002 provides a list of S/Ns 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.
SIL No. PMC 26-003 provides a list of S/Ns 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.

Costs of Compliance

We estimate that this 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 AD:


Estimated Costs

Action Labor cost Parts cost Cost per product
Inspection 0.2 work-hours x $85 per hour = $17 $0 $17
Replacement 0.8 work-hours x $85 per hours = $68 1,285 1,353

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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to engines, propellers, and
appliances to the Manager, Engine and Propeller Standards Branch,
Policy and Innovation Division.

Regulatory Findings

We 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 this AD:
(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.
