Airworthiness Directives; Cessna Aircraft Company (Cessna) Model 
172 Airplanes Modified by Supplemental Type Certificate (STC) SA01303WI

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

[[Page 22299]]

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD requires installing a full authority 
digital engine control (FADEC) backup battery, replacing the supplement 
pilot's operating handbook and FAA approved airplane flight manual, and 
replacing the FADEC backup battery every 12 calendar months. This AD 
was prompted by an incident where an airplane experienced an in-flight 
engine shutdown caused by a momentary loss of electrical power to the 
FADEC. We are issuing this AD to prevent interruption of electrical 
power to the FADEC, which could result in an uncommanded engine 
shutdown. This failure could lead to a loss of engine power.

DATES: This AD is effective May 26, 2011.
    Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of May 26, 2011.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
the specified products. That NPRM published in the Federal Register on 
December 15, 2010 (75 FR 78177). That NPRM proposed to require 
installing a FADEC backup battery, replacing the supplement pilot's 
operating handbook and FAA approved airplane flight manual, and 
replacing the FADEC backup battery every 12 calendar months.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the proposal 
and the FAA's response to the comment.

Request

    Rob van den Bosch, Thielert Aircraft Engines GmbH, when referring 
to the airplane maintenance manual (AMM) and airplane flight manual 
(AFM) supplement, recommended adding ``or later approved issue or 
revision.'' The commenter reasoned that future changes to the AMM or 
AFM would require additional work by the FAA to update the AD.
    We disagree with the recommendation. If we would include such 
language, it would violate regulation, specifically 1 CFR 51.1, 
paragraph (f), which states ``Incorporation by reference of a 
publication is limited to the edition of the publication that is 
approved. Future amendments or revisions of the publication are not 
included.''. Service information that we incorporate by reference in an 
AD is often revised after we issue the AD. We can approve later 
revisions of service information as an alternative method of compliance 
(AMOC).
    The FAA is not changing this AD as a result of this comment.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD as proposed except for minor editorial changes. We have determined 
that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 14 airplanes of U.S. registry.
    We estimate the following costs 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

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a

[[Page 22300]]

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.
