Hours TIS factor 1 For the purposes of this AD, an external load operation occurs each time a helicopter picks up an external load and drops it off. Any external load lift in which the helicopter achieves a vertical altitude difference of greater than 200 feet indicated attitude between the pick-up and drop-off point counts as two external load lifts in determining the proper rate per hour category. mstockstill on DSK4VPTVN1PROD with PROPOSALS Note 1: The number of unfactored hours TIS and factored hours TIS contained in Table 1 of this AD are examples and presented for illustration purposes only. (4) By reference to Table 1 of this AD, enter the ‘‘Unfactored Hours TIS’’ for each category as determined by paragraph (a)(3) of this AD. Calculate the ‘‘Factored Hours TIS’’ by multiplying the ‘‘Unfactored Hours TIS’’ by the ‘‘Hours TIS Factor.’’ Determine the accumulated ‘‘Total Factored Hours TIS’’ on each yoke by adding the factored hours TIS for each type of operation and helicopter model. Tracking the Total Factored Hours TIS is only for establishing a retirement life and not for tracking inspection intervals. (5) Record the accumulated Total Factored Hours TIS on the component history card or equivalent record for each yoke. (6) Continue to factor the hours TIS for each yoke by following paragraph (a)(2) through (a)(4) of this AD, and record the additional factored hours TIS on the component history card or equivalent record. (b) For helicopters with yoke, P/N 204– 011–102 (all dash numbers), installed, before further flight, unless accomplished previously: (1) For hours TIS accumulated before the effective date of this AD, calculate and record the Total Factored Hours TIS as follows: (i) For the Model 212 helicopters, 1 hour TIS in which passenger or internal cargo was carried equals 1 factored hour TIS; 1 hour TIS where more than 4 external load lifts occurred equals 5 factored hours TIS. (ii) For the Model 204 and 205 series helicopters, 1 hour TIS equals 1 factored hour TIS. Note 2: Paragraph (b)(1) gives credit to the operators for compliance with ADs 81–19–01 and 81–19–02 in establishing the starting point for the new factoring of hours TIS contained in this AD. Note 3: The accumulated Total Factored Hours TIS for yoke, P/N 204–011–102 (all dash numbers), calculated in accordance with the applicable Bell Model 204B, 205A– 1, 205B, or 212 maintenance manuals, which results in an equal or higher accumulated Total Factored Hours TIS is an acceptable alternative to meeting the factoring requirements of AD 81–19–01 (contained in Bell ASB 212–81–23, dated June 22, 1981, for the Model 212 helicopters) and AD 81–19– 02 (contained in Bell ASBs 204–81–11 and VerDate Mar<15>2010 17:10 Nov 01, 2011 Jkt 226001 205–81–16, both dated June 22, 1981, for the Model 204 and 205 series helicopters). (2) For hours TIS accumulated after the effective date of this AD, calculate and record the factored hours TIS on the yoke in accordance with the requirements of paragraphs (a)(1) thorough (a)(6) of this AD. (c) Revise the Airworthiness Limitations section of the applicable maintenance manuals or the Instructions for Continued Airworthiness (ICAs) by establishing a new retirement life of 3,600 Total Factored Hours TIS for each yoke, P/N AAI–4011–102 (all dash numbers), ASI–4011–102 (all dash numbers), or 204–011–102 (all dash numbers), by making pen and ink changes or inserting a copy of this AD into the Airworthiness Limitations section of the maintenance manual or ICAs. (d) Unless accomplished previously, record a life limit of 3,600 Total Factored Hours TIS for each yoke, P/N AAI–4011–102 (all dash numbers), ASI–4011–102 (all dash numbers), or 204–011–102 (all dash numbers), on the component history card or equivalent record. (e) Within 100 hours TIS or 600 hours TIS since the last magnetic particle inspection (MPI) of the yoke, whichever occurs later, and thereafter at intervals not to exceed 600 hours TIS, for any yoke installed on any Model 205B or 212 helicopter: (1) Remove the yoke from the main rotor hub assembly (hub). Using a 5-power or higher magnifying glass, visually inspect each pillow block bushing hole, spindle radius, and center section web for any corrosion or mechanical damage. (2) Perform an MPI of each yoke for a crack. Note 4: MPI procedures are contained in Bell Standard Practices Manual BHT–ALL– SPM. (f) Within 100 hours TIS or 2,400 hours TIS since the last MPI of the yoke, whichever occurs later, and thereafter at intervals not to exceed 2,400 hours TIS, for any yoke installed on any Model 204B, 205A, or 205A– 1 helicopter: (1) Remove the yoke from the hub. Using a 5-power or higher magnifying glass, visually inspect each pillow block bushing hole, spindle radius, and center section web for any corrosion or mechanical damage. (2) Perform an MPI of each yoke for a crack. (g) Before further flight, replace each yoke with an airworthy yoke if: PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 (1) The yoke has 3,600 or more Total Factored Hours TIS; or (2) The Total Factored Hours TIS for the yoke is unknown and cannot be determined; or (3) The yoke has any corrosion or mechanical damage that exceeds any of the maximum repair damage limits; or Note 5: The applicable Bell Component and Repair Overhaul Manual contains the maximum repair damage limitations. (4) The yoke has a crack. (h) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19.

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– 2011–1212; Directorate Identifier 2011– CE–034–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 two reports of partial loss of engine power due to dislodged rubber gaskets/seals being ingested into one of the two turbochargers. The gasket/seal is located between the air-box mounting base and the turbochargers. Once the gasket/seal is ingested into a turbocharger the engine will experience a partial loss of power as the turbocharger fails to perform its function. A complete loss of power could occur if metal debris from the failing turbocharger migrates into the engine oil system and damages other engine components. Examination by Cirrus of other Cirrus Model SR22T airplanes showed early evidence of the gasket/seal starting to dislodge on at least one other airplane. This condition, if not corrected, could result in engine failure. Relevant Service Information We reviewed Cirrus Design Corporation SR22T Service Bulletin SB 2X–71–17 R1, dated September 30, 2011. The service information describes procedures for replacement of the air box seals. 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 inspection and modification of the air box flange welds and slots and installation of air box seals and adhesive with materials better suited for the hightemperature environment encountered in close proximity to the turbocharger. Costs of Compliance We estimate that this proposed AD affects 67 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Labor cost Replacement of the induction system air box seals and extension of air box flange slots. mstockstill on DSK4VPTVN1PROD with PROPOSALS Action 2.5 work-hours × $85 per hour = $212.50. 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 VerDate Mar<15>2010 17:10 Nov 01, 2011 Jkt 226001 Parts cost 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 PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 $139 Cost per product $351.50 Cost on U.S. operators $23,550.50 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: E:\FR\FM\02NOP1.SGM 02NOP1 Federal Register / Vol. 76, No. 212 / Wednesday, November 2, 2011 / Proposed Rules ‘‘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.

Discussion

    We received two reports of partial loss of engine power due to 
dislodged rubber gaskets/seals being ingested into one of the two 
turbochargers. The gasket/seal is located between the air-box mounting 
base and the turbochargers. Once the gasket/seal is ingested into a 
turbocharger the engine will experience a partial loss of power as the 
turbocharger fails to perform its function. A complete loss of power 
could occur if metal debris from the failing turbocharger migrates into 
the engine oil system and damages other engine components. Examination 
by Cirrus of other Cirrus Model SR22T airplanes showed early evidence 
of the gasket/seal starting to dislodge on at least one other airplane.
    This condition, if not corrected, could result in engine failure.

Relevant Service Information

    We reviewed Cirrus Design Corporation SR22T Service Bulletin SB 2X-
71-17 R1, dated September 30, 2011. The service information describes 
procedures for replacement of the air box seals.

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 inspection and modification of the 
air box flange welds and slots and installation of air box seals and 
adhesive with materials better suited for the high-temperature 
environment encountered in close proximity to the turbocharger.

Costs of Compliance

    We estimate that this proposed AD affects 67 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

    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:

[[Page 67633]]

``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

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new 
airworthiness directive (AD):

Cirrus Design Corporation: Docket No. FAA-2011-1212; Directorate 
Identifier 2011-CE-034-AD.

(a) Comments Due Date

    We must receive comments by December 19, 2011.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the following model and serial number 
airplanes, certificated in any category:
    (1) Group 1 Airplanes: Cirrus Design Corporation Model SR22T 
airplanes, serial numbers 0001 through 0169, except 0004, 0019, 
0027, 0047, 0097, 0126, 0127, 0135, 0138, 0139, 0144, 0154, 0155, 
0157, 0158, 0159, 0160, 0161, and 0163.
    (2) Group 2 Airplanes: Cirrus Design Corporation Model SR22T 
airplanes, serial numbers 0004, 0019, 0027, 0047, 0097, 0126, 0127, 
0135, 0138, 0139, 0144, 0155, 0157, 0158, 0160, and 0161. These 
airplanes had the reinforced silicone fiberglass seals installed at 
the factory but the box flange welds and slots may be incorrectly 
modified. Therefore, this AD still applies to these airplanes.

(d) Subject

    Joint Aircraft System Component (JASC) Code 7160, Engine Air 
Intake.

(e) Unsafe Condition

    This AD was prompted by reports of partial loss of engine power 
due to a dislodged rubber gasket/seal being ingested into the 
turbocharger. We are issuing this AD to inspect and modify the air 
box flange welds and slots and install induction system air box 
seals as applicable.

(f) Compliance

    Comply with this AD following Cirrus Design Corporation SR22T 
Service Bulletin SB 2X-71-17 R1, dated September 30, 2011, within 
the compliance times specified, unless already done.

(g) Actions

    (1) Group 1 Airplanes: Within the next 10 hours time-in-service 
(TIS) after the effective date of this AD, inspect the air box 
flange welds and slots, make modifications as necessary, and replace 
the induction air box seals with reinforced silicone fiberglass 
seals part number 29486-001.
    (2) Group 2 Airplanes: Within the next 10 hours TIS after the 
effective date of this AD, inspect the air box flange welds and 
slots and, as necessary, make modifications.

    Note: Credit will be given for actions required in paragraphs 
(g)(1) and (g)(2) of this AD if already done before the effective 
date of this AD following Cirrus Design Corporation SR22T Service 
Bulletin SB 2X-71-17, dated July 21, 2011.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Chicago Aircraft Certification Office (ACO),
