We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We received reports of control cable assembly failures that may lead to failure of the horizontal stabilator control system on Piper PA–28, PA–32, PA–34, and PA–44 airplanes. We have had reports of cracks, corrosion, failure of the turnbuckle, control cable fraying, the cable swage end broken and the system being held together by turnbuckle safety wire. In one report, an elevator cable was found broken at the terminal end near the turnbuckle, and, in another report, the elevator cable failed at the fitting that treads into the turnbuckle. This condition, if not corrected, could result in failure of the horizontal stabilator control system with subsequent loss of pitch control. Relevant Service Information We reviewed Piper Aircraft, Inc. Mandatory Service Bulletin No. 1245, dated May 3, 2012. That service information describes procedures for inspections of the stabilator control system. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require inspections of the stabilator control system and replacement of parts as necessary. We are proposing this AD to correct the unsafe condition on these products. Costs of Compliance We estimate that this proposed AD affects 34,013 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\02AUP1.SGM 02AUP1 45980 Federal Register / Vol. 77, No. 149 / Thursday, August 2, 2012 / Proposed Rules ESTIMATED COSTS Cost per product Action Labor cost Parts cost Inspection of the horizontal stabilator control system. 5 work-hours × $85 per hour = $425 .........

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. TKELLEY on DSK3SPTVN1PROD with PROPOSALS Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132.

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2012-0731; 
Directorate Identifier 2012-CE-020-AD'' at the beginning of your

receive about this proposed AD.

Discussion

    We received reports of control cable assembly failures that may 
lead to failure of the horizontal stabilator control system on Piper 
PA-28, PA-32, PA-34, and PA-44 airplanes. We have had reports of 
cracks, corrosion, failure of the turnbuckle, control cable fraying, 
the cable swage end broken and the system being held together by 
turnbuckle safety wire. In one report, an elevator cable was found 
broken at the terminal end near the turnbuckle, and, in another report, 
the elevator cable failed at the fitting that treads into the 
turnbuckle. This condition, if not corrected, could result in failure 
of the horizontal stabilator control system with subsequent loss of 
pitch control.

Relevant Service Information

    We reviewed Piper Aircraft, Inc. Mandatory Service Bulletin No. 
1245, dated May 3, 2012. That service information describes procedures 
for inspections of the stabilator control system.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require inspections of the stabilator 
control system and replacement of parts as necessary. We are proposing 
this AD to correct the unsafe condition on these products.

Costs of Compliance

    We estimate that this proposed AD affects 34,013 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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, 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.

    This AD was prompted by reports of control cable assembly 
failures that may lead to failure of the horizontal stabilator 
control system and could result in loss of pitch control. This 
proposed AD would require inspections of the stabilator control 
system and replacement of parts as necessary. We are issuing this AD 
to correct the unsafe condition on these products.

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspection

    (1) As of the effective date of this AD, if the age of the 
airplane is at or exceeds 15 years, then at the next annual 
inspection or within the next 12 months after the effective date of 
this AD, whichever occurs later, do an initial inspection of the 
stabilator control system following instructions 1 through 10 of 
Piper Aircraft, Inc. Mandatory Service Bulletin No. 1245, dated May 
3, 2012.
    (2) As of the effective date of this AD, if the age of the 
airplane is less than 15 years, then, upon the age of the airplane 
reaching 15 years, at the next annual inspection or within the next 
12 months after the effective date of this AD, whichever occurs 
later, do an initial inspection of the stabilator control system 
following instructions 1 through 10 of Piper Aircraft, Inc. 
Mandatory Service Bulletin No. 1245, dated May 3, 2012.
    (3) As of the effective date of this AD, if the age of the 
airplane cannot be determined, then at the next annual inspection or
