SUPPLEMENTARY INFORMATION: 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– 2012–0962; Directorate Identifier 2012– CE–033–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We received a report of an accident of a Cessna Aircraft Company Model 172RG airplane where a fire started inflight on the cabin side of the firewall and rapidly accelerated. The fire originated from the area of the landing gear’s hydraulic power pack system and resulted in a complete hull loss with reported injuries. The investigation concluded that an in-flight fire may result from improper installation of the terminal lugs, improper installation of (or missing) terminal covers and associated wiring to the landing gear hydraulic power pack motor wiring, which was not properly protected or adequately secured. The cause for the rapid acceleration of the fire was indicative of the presence of flammable materials or a flammable material source near or in contact with the hydraulic power pack system within the aircraft’s cockpit/cabin. This style of hydraulic power pack is also used on Cessna Aircraft Company Models R182, TR182, FR182, 210N, T210N, 210R, T210R, P210N, P210R, and T303 airplanes. This condition, if not corrected, could result in a fire in the aircraft’s cockpit, damage and or loss of aircraft, and injuries and or fatalities. Relevant Service Information We reviewed Cessna Aircraft Company Service Letter MEL–29–01, dated July 14, 2012; and Service Letter SEL–29–01, dated July 16, 2012. The service information describes procedures for inspection of the aircraft’s hydraulic power pack system for proper wire routing, protective cover, and hydraulic leaks, and if needed, installation of a protective cover and rerouting of wiring. 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 these same type designs. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance We estimate that this proposed AD affects 2,961 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Hydraulic power pack system wiring inspection. 1 work-hour × $85 per hour = $85 ........... Not applicable ........... $85 $251,685 We estimate the following costs to do any necessary hydraulic power pack terminal lug protective cap installation that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need this installation: ON-CONDITION COSTS Labor cost Parts cost Cost per product Hydraulic power pack system wiring installation .......... srobinson on DSK4SPTVN1PROD with PROPOSALS Action 1 work-hour × $85 per hour = $85 ............................... $29 $114 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: VerDate Mar<15>2010 18:01 Sep 10, 2012 Jkt 226001 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: PO 00000 Frm 00035 Fmt 4702 Sfmt 4702 ‘‘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 E:\FR\FM\11SEP1.SGM 11SEP1 55772 Federal Register / Vol. 77, No. 176 / Tuesday, September 11, 2012 / Proposed Rules 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.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. AGENCY: We are revising an earlier proposed airworthiness directive (AD) for all The Boeing Company Model DC– 9–81 (MD–81), DC–9–82 (MD–82), DC– 9–83 (MD–83), DC–9–87 (MD–87), and MD–88 airplanes. That NPRM proposed repetitive high frequency eddy current (HFEC) inspections for cracking of the left and right rib hinge bearing lugs of the aft face of the center section of the horizontal stabilizer; measuring crack length and blending out cracks; and replacing the horizontal stabilizer center section rib, if necessary. That NPRM was prompted by reports of cracks of the hinge bearing lugs of the center section ribs of the horizontal stabilizer. This action revises that NPRM by adding the requirement for rib replacement if cracking is found during certain inspections of this proposed AD. We are proposing this supplemental NPRM to detect and correct cracking in the hinge bearing lugs of the horizontal stabilizer center section ribs, which could result in failure of the lugs, resulting in the inability of the horizontal stabilizer to sustain the required limit loads and consequent loss of control of the airplane. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

Discussion We issued an NPRM to amend 14 CFR part 39 to include an AD that would apply to The Boeing Company Model DC–9–81 (MD–81), DC–9–82 (MD–82), DC–9–83 (MD–83), DC–9–87 (MD–87), and MD–88 airplanes. That NPRM published in the Federal Register on August 26, 2011 (76 FR 53346). That NPRM proposed to require repetitive HFEC inspections for cracking of the left and right rib hinge bearing lugs of the aft face of the center section of the horizontal stabilizer; measuring crack length and blending out cracks; and replacing the horizontal stabilizer center section rib, if necessary. Actions Since NPRM (76 FR 53346, August 26, 2011) Was Issued Since we issued the previous NPRM (76 FR 53346, August 26, 2011), we determined a required corrective action was not specified by Boeing Alert Service Bulletin MD80–55A069, dated January 19, 2011. Therefore, we propose to add a requirement for rib replacement if cracking is found during certain inspections required by this supplemental NPRM. Comments We gave the public the opportunity to comment on the previous NPRM (76 FR 53346, August 26, 2011). The following presents the comments received on the NPRM and the FAA’s response to each comment. Support for the NPRM (76 FR 53346, August 26, 2011) Boeing stated it supports the NPRM (76 FR 53346, August 26, 2011).

Airworthiness Directives; Cessna Aircraft Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Cessna Aircraft Company Models 172RG, R182, TR182, FR182, 210N, 
T210N, 210R, T210R, P210N, P210R, and T303 airplanes. This proposed AD 
was prompted by a report of a cockpit fire that appeared to originate 
from the area of the landing gear's hydraulic power pack system. This 
proposed AD would require you inspect the aircraft's hydraulic power 
pack wiring for incorrect installation, and if needed, correct the 
installation. We are proposing this AD to correct the unsafe condition 
on these products.

DATES: We must receive comments on this proposed AD by October 26,

Discussion

    We received a report of an accident of a Cessna Aircraft Company 
Model 172RG airplane where a fire started in-flight on the cabin side 
of the firewall and rapidly accelerated. The fire originated from the 
area of the landing gear's hydraulic power pack system and resulted in 
a complete hull loss with reported injuries.
    The investigation concluded that an in-flight fire may result from 
improper installation of the terminal lugs, improper installation of 
(or missing) terminal covers and associated wiring to the landing gear 
hydraulic power pack motor wiring, which was not properly protected or 
adequately secured. The cause for the rapid acceleration of the fire 
was indicative of the presence of flammable materials or a flammable 
material source near or in contact with the hydraulic power pack system 
within the aircraft's cockpit/cabin.
    This style of hydraulic power pack is also used on Cessna Aircraft 
Company Models R182, TR182, FR182, 210N, T210N, 210R, T210R, P210N, 
P210R, and T303 airplanes.
    This condition, if not corrected, could result in a fire in the 
aircraft's cockpit, damage and or loss of aircraft, and injuries and or 
fatalities.

Relevant Service Information

    We reviewed Cessna Aircraft Company Service Letter MEL-29-01, dated 
July 14, 2012; and Service Letter SEL-29-01, dated July 16, 2012. The 
service information describes procedures for inspection of the 
aircraft's hydraulic power pack system for proper wire routing, 
protective cover, and hydraulic leaks, and if needed, installation of a 
protective cover and rerouting of wiring.

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 these same type 
designs.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 2,961 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
            Action                  Labor cost              Parts cost              product         operators

Hydraulic power pack system     1 work-hour x $85  Not applicable.............             $85         $251,685
 wiring inspection.              per hour = $85.
----------------------------------------------------------------------------------------------------------------

     We estimate the following costs to do any necessary hydraulic 
power pack terminal lug protective cap installation that would be 
required based on the results of the proposed inspection. We have no 
way of determining the number of aircraft that might need this 
installation:

                                               On-Condition Costs

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

[[Page 55772]]

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.
