For these tasks, the initial compliance time starts at the applicable time specified in paragraphs (g)(1) and (g)(2) of this AD. Thereafter, except as provided by paragraph (h) of this AD, no alternative functional check of the thermal switch or detailed visual inspection of the piccolo tube may be approved. Note 1: The actions required by paragraph (g) of this AD may be done by inserting a copy of Bombardier TR 2A–49 and TR 2A– 50, both dated November 17, 2009, into the Appendix A of Part 2 of the Bombardier CL– 600–2B19 MRM. When these TRs have been included in Appendix A of Part 2 of the general revisions of the MRM, the general revisions may be inserted in the MRM, provided that the relevant information in the general revision is identical to that in Bombardier TR 2A–49 and TR 2A–50, both dated November 17, 2009. (1) For Task Number C36–20–133–03, the initial compliance time is before the accumulation of 15,000 total flight hours or within 7 months after the effective date of this AD, whichever occurs later.

Corrective actions are considered FAAapproved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120–0056.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Model 747–200B, –300, –400, –400D, and –400F series airplanes. This proposed AD would require an inspection to determine the part number of the door and to determine if the correct mid-pivot access door is installed, and the installation of a marker on the mid-pivot access door, and if necessary, repetitive ultrasonic inspections for cracking of the midpivot bolt assembly and eventual replacement of the mid-pivot bolt assembly. This proposed AD results from a report that the left and right spring beam mid-pivot bolt assembly access doors for the No. 1 strut were inadvertently installed in the incorrect position during strut modification. We are proposing this AD to detect and correct incorrectly installed mid-pivot bolt assemblies on the spring beam on the outboard struts. Incorrectly installed bolt assemblies could lead to fatigue cracking and consequent fracturing of the mid-pivot bolt assembly, which could lead to loss of the spring beam load path and the possible separation of a strut and engine from the airplane during flight. DATES: We must receive comments on this proposed AD by December 30, 2010. SUMMARY: You may send comments by any of the following methods: ADDRESSES: E:\FR\FM\15NOP1.SGM 15NOP1

Airworthiness Directives; Rolls-Royce plc RB211-Trent 768, 772, 
and 772B Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM); rescission.

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

SUMMARY: We propose to rescind an airworthiness directive (AD) for the 
products listed above. The existing AD, AD 98-09-27, resulted from 
aircraft certification testing which revealed that stresses on the 
thrust reverser hinge were higher than had been anticipated during 
engine certification, and the United Kingdom Civil Aviation Authority, 
issuing AD 008-03-97.
    Since we issued AD 98-09-27, we discovered that its requirements 
were duplicated in airplane-level AD 2001-09-14, issued by the FAA 
Transport Airplane Directorate. This proposal to rescind the engine-
level AD allows the public the opportunity to comment on the FAA's 
determination of the duplication of requirements in another AD, before 
we rescind the engine-level AD.

DATES: We must receive comments on this proposed AD by December 30, 
2010.

    You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Operations office

complete Privacy Act Statement in the Federal Register published on

Discussion

    On April 23, 1998, the FAA Engine & Propeller Directorate issued 
engine AD 98-09-27 (63 FR 24911, May 6, 1998). On April 30, 2001, the 
FAA Transport Airplane Directorate issued airplane AD 2001-09-14 (66 FR 
23838, May 10, 2001). Those ADs both require the same initial and 
repetitive visual inspections of Rolls-Royce plc RB211-Trent 768 and 
772 series turbofan engine thrust reverser hinge lugs and attachment 
ribs for cracks, and, if necessary, removal from service and 
replacement with serviceable parts.
    Since we issued engine AD 98-09-27 and airplane AD 2001-09-14, we 
determined that duplicate ADs to address the same unsafe condition were 
unnecessary.

FAA's Determination and Requirements of This Proposed AD Rescission

    We are proposing this AD rescission of AD 98-09-27 because we 
evaluated all information and determined that two FAA ADs with the same 
requirements are not necessary.

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 rescission would not have 
federalism implications under Executive Order 13132. This proposed AD 
rescission 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 rescission 
of a 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); and
    3. 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 rescission and placed it in the AD docket.
