14 CFR Part 39

[Docket No. FAA-2010-1006; Directorate Identifier 2009-CE-057-AD; 
Amendment 39-16543; AD 2010-26-04]
RIN 2120-AA64


Airworthiness Directives; Piper Aircraft, Inc. Model PA-28-161 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above that are equipped with Thielert Aircraft Engine 
GmbH (TAE) Engine Model TAE-125-01 installed per Supplemental Type 
Certificate (STC) No. SA03303AT. 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 revising the limitations section of the supplement airplane 
maintenance manual. This AD was prompted by an incident where an 
airplane experienced an in-flight engine shutdown caused by a momentary 
loss

[[Page 81418]]

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 February 1, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publication listed in the AD as of February 1, 
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 
October 6, 2010 (75 FR 61655). That NPRM proposed to require 
installation of a FADEC backup battery, replacement of the supplement 
pilot's operating handbook and FAA approved airplane flight manual, and 
revision of the limitations section of the supplement airplane 
maintenance manual.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data 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 zero 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 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.
