Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2013-0262; Directorate Identifier 2013-NE-13-AD; 
Amendment 39-17548; AD 2013-16-10]

Airworthiness Directives; Hamilton Standard Division and Hamilton 
Sundstrand Corporation Propellers

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

[[Page 49661]]

SUMMARY: We are adopting a new airworthiness directive (AD) for 
Hamilton Standard Division model 6/5500/F and 24PF and Hamilton 
Sundstrand Corporation model 14RF, 14SF, 247F, and 568F series 
propellers. This AD was prompted by the amount of corrosion detected 
during major inspections (MI). This AD requires incorporating 
inspections, based on a calendar time, into the propeller maintenance 
schedule. We are issuing this AD to prevent corrosion that could result 
in propeller failure and loss of airplane control.

DATES: This AD is effective September 19, 2013.

ADDRESSES: The Docket Operations office is located at Docket Management 
Facility, U.S. Department of Transportation, 1200 New Jersey Avenue 
SE., West Building Ground Floor, Room W12-140, Washington, DC 20590-
0001.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
The NPRM published in the Federal Register on May 23, 2013 (78 FR 
30795). The NPRM proposed to require incorporating inspections, based 
on a calendar time, into the propeller maintenance schedule.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 30795, May 23, 
2013) 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 this 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 (78 FR 30795, May 23, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 30795, May 23, 2013).

Costs of Compliance

    We estimate that this AD affects about 1,044 propeller/hub 
combinations installed on airplanes of U.S. registry. We also estimate 
that it will take about 160 hours per propeller to perform one MI. The 
average labor rate is $85 per hour. Based on these figures, we estimate 
the cost of this AD on U.S. operators to be $14,198,400.

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 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.
