Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2010-1243; Directorate Identifier 2010-CE-058-AD; Amendment 39-16626; AD 2011-06-02]

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.
––––––––––––––––––––––––––––––––––
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:
Estimated Costs
Action
Labor cost
Parts cost
Cost per product
Cost on U.S. operators
For airplanes with a 14-volt battery system; installation of a 14-volt FADEC backup battery.
24 work-hours X $85 per hour = $2,040
$820
$2,860
$14,300
For airplanes with a 28-volt battery system; installation of a 28-volt FADEC backup battery.
24 work-hours X $85 per hour = $2,040
$1,160
$3,200
$28,800
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 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.
