Airworthiness Directives; Cessna Aircraft Company Airplanes, 2659-2662 [2012-855]

Download as PDF Federal Register / Vol. 77, No. 12 / Thursday, January 19, 2012 / Proposed Rules parts would cost about $19 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $22,742, or $274 per product. 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. EMCDONALD on DSK29S0YB1PROD with PROPOSALS 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 560XL airplanes. This proposed AD was prompted by reports of wheel inserts becoming loose and damaging brake assemblies on Model 560XL airplanes. This proposed AD would require an inspection of the torque lug and surrounding components (wheel base, side rim, lock ring) for damage (such as corrosion, cracks, dents, bent areas, damaged or missing paint or primer, or SUMMARY: E:\FR\FM\19JAP1.SGM 19JAP1 2660 Federal Register / Vol. 77, No. 12 / Thursday, January 19, 2012 / Proposed Rules wear on the metal), and of the bearing cup for corrosion, turned cup, or clearance that exceeds limits, and repair as applicable; measuring the torque lugs for width and replacing screws and inserts with new, improved screws and inserts; and re-identifying the wheel assemblies. We are proposing this AD to correct the unsafe condition on these products. We must receive comments on this proposed AD by March 5, 2012.

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– 2011–1413; Directorate Identifier 2011– NM–062–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 https:// 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 have received reports of wheel inserts becoming loose and damaging brake assemblies on Model 560XL airplanes. In two cases, a loose wheel insert damaged the brake housing at a location that affects both the antiskid brake hydraulic system and the emergency brake system. In those two cases, both systems failed to stop the airplane on the runway. This condition, if not corrected, could result in brake failure, and consequently an airplane not being able to stop on the runway. Relevant Service Information We reviewed Cessna Service Bulletin SB560XL–32–41, Revision 1, dated May 5, 2011, including Service Bulletin Supplemental Data SB560XL–32–41, dated February 25, 2011. That service bulletin describes procedures for doing a general visual inspection of the torque lug and surrounding components (wheel base, side rim, lock ring) for damage (such as corrosion, cracks, dents, bent areas, damaged or missing paint or primer, or wear on the metal), and of the bearing cup for corrosion, turned cup, or clearance that exceeds limits, and repair if necessary; measuring the torque lugs for width and replacing screws and inserts with new, improved screws and inserts; and re-identifying the wheel assemblies. 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 accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Difference Between the Proposed AD and the Service Information.’’ Difference Between the Proposed AD and the Service Information Operators should note that, although the Accomplishment Instructions of Cessna Service Bulletin SB560XL–32– 41, Revision 1, dated May 5, 2011, describe procedures for submitting a comment sheet related to service bulletin quality and a sheet recording compliance with the service bulletin, this proposed AD would not require those actions. Costs of Compliance We estimate that this proposed AD affects 473 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 Inspection, and measurement of the torque lugs, replacement of screws and inserts, and re-marking. Up to 11 work-hours × $85 per hour = $935. Up to $6,462 .............. Up to $7,397 .............. VerDate Mar<15>2010 17:01 Jan 18, 2012 Jkt 226001 PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 E:\FR\FM\19JAP1.SGM 19JAP1 Cost on U.S. operators Up to $3,498,781 Federal Register / Vol. 77, No. 12 / Thursday, January 19, 2012 / Proposed Rules We estimate the following costs to do any necessary repairs or replacements as applicable that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that 2661 might need these repairs or replacements: ON-CONDITION COSTS Action Labor cost Parts cost Repair or replacement as applicable ........ Between 1 and 9 work-hour[s] × $85 per hour = Between $85 and $765 per wheel assembly. Between $0 and $24,000 per wheel assembly. According to the manufacturer, all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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. EMCDONALD on DSK29S0YB1PROD with PROPOSALS 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 VerDate Mar<15>2010 14:58 Jan 18, 2012 Jkt 226001 (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.

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 Model 560XL airplanes. This proposed AD 
was prompted by reports of wheel inserts becoming loose and damaging 
brake assemblies on Model 560XL airplanes. This proposed AD would 
require an inspection of the torque lug and surrounding components 
(wheel base, side rim, lock ring) for damage (such as corrosion, 
cracks, dents, bent areas, damaged or missing paint or primer, or

[[Page 2660]]

wear on the metal), and of the bearing cup for corrosion, turned cup, 
or clearance that exceeds limits, and repair as applicable; measuring 
the torque lugs for width and replacing screws and inserts with new, 
improved screws and inserts; and re-identifying the wheel assemblies. 
We are proposing this AD to correct the unsafe condition on these 
products.

Discussion

    We have received reports of wheel inserts becoming loose and 
damaging brake assemblies on Model 560XL airplanes. In two cases, a 
loose wheel insert damaged the brake housing at a location that affects 
both the antiskid brake hydraulic system and the emergency brake 
system. In those two cases, both systems failed to stop the airplane on 
the runway. This condition, if not corrected, could result in brake 
failure, and consequently an airplane not being able to stop on the 
runway.

Relevant Service Information

    We reviewed Cessna Service Bulletin SB560XL-32-41, Revision 1, 
dated May 5, 2011, including Service Bulletin Supplemental Data 
SB560XL-32-41, dated February 25, 2011. That service bulletin describes 
procedures for doing a general visual inspection of the torque lug and 
surrounding components (wheel base, side rim, lock ring) for damage 
(such as corrosion, cracks, dents, bent areas, damaged or missing paint 
or primer, or wear on the metal), and of the bearing cup for corrosion, 
turned cup, or clearance that exceeds limits, and repair if necessary; 
measuring the torque lugs for width and replacing screws and inserts 
with new, improved screws and inserts; and re-identifying the wheel 
assemblies.

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 accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Difference Between the Proposed AD and the Service 
Information.''

Difference Between the Proposed AD and the Service Information

    Operators should note that, although the Accomplishment 
Instructions of Cessna Service Bulletin SB560XL-32-41, Revision 1, 
dated May 5, 2011, describe procedures for submitting a comment sheet 
related to service bulletin quality and a sheet recording compliance 
with the service bulletin, this proposed AD would not require those 
actions.

Costs of Compliance

    We estimate that this proposed AD affects 473 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

 marking.
----------------------------------------------------------------------------------------------------------------


[[Page 2661]]

    We estimate the following costs to do any necessary repairs or 
replacements as applicable 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 these repairs or replacements:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------

                                       = Between $85 and $765
                                       per wheel assembly.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, all of the costs of this proposed AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.

cup, and re-identifying the wheel assemblies.


    Note 2: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''

(h) Parts Installation

    As of the effective date of this AD, no person may install, on 
any airplane, a wheel
