Regulatory Findings We have 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 that the 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); 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 and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety.

Based on the current Trent 800 fleet and the service experience demonstrated since we published the AD and NPRM, the underlying unsafe conditions no longer justify that AD. 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. FAA’s Conclusions After reviewing the available data, we determined it is appropriate to rescind AD 97–06–13 to eliminate the mandate to perform inspections and hardware replacements. The inspections and hardware replacements are no longer required to correct an unsafe condition. Operators should however, incorporate those inspections and replacements into their normal maintenance schedules. Our determination is based on the following: We based AD 97–06–13 on a determination of unsafe conditions on a fleet of engines that had a total operating experience of 29,000 hours. Today’s fleet of engines has over 1.6 million operating hours, with a basic inflight shutdown rate of well below acceptable levels. Fleet experience does not support the original unsafe condition determination. The Civil Aviation Authority (CAA), which is the airworthiness authority for the United Kingdom, determined that their AD on the subject is no longer needed. They withdrew their AD, and they recommend we do likewise. RollsRoyce plc, with CAA approval, withdrew the inspection service bulletins referenced in the AD. The fleet has completely incorporated the modifications required by AD 97–06–13, intended to prevent oil leaks. This proposed action would rescind AD 97–06–13. Rescission of AD 97–06– 13 would constitute only such action and if followed by a final action would not preclude the agency from issuing another action in the future nor would it commit the agency to any course of action in the future.

Discussion We proposed to amend 14 CFR part 39 with a notice of proposed rulemaking (NPRM) for an airworthiness directive (AD) (the ‘‘original NPRM’’). The original NPRM applies to certain BAE Systems (Operations) Limited Model BAe 146 airplanes. The original NPRM was published in the Federal Register on November 15, 2005 (70 FR 69286). The original NPRM proposed to require repetitive inspections to measure the depth of chafing or scoring in the skin along the full length of the wing-tofuselage fairing from forward to aft ends at the contact between the seal and fuselage, and related investigative/ corrective actions if necessary. The original NPRM provided credit for accomplishment of certain service bulletins before the effective date of the AD. Since the original NPRM was issued, we have learned that two of the documents (BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53–005, dated August 15, 1984, and ISB.53–067, dated December 23, 1987) are unavailable. We are therefore unable to determine the appropriateness of all of the procedures described in the service bulletin and must remove those references from this supplemental NPRM. Comments We have considered the following comments on the original NPRM. Request To Correct Typographical Errors The commenter, on behalf of Air Wisconsin Airlines Corporation, notes that the proposed AD misidentified two reference documents. In paragraph (c), the last Modification number should be HCM01698A. In paragraph (i), Table 1, the date listed for ISB.53–005, Revision 1, should be April 19, 1985. We have corrected these references in this supplemental NPRM. Additional Change to Original NPRM We have revised the statement of the unsafe condition to clarify the effect of chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from the forward to aft ends at the contact between the seal and fuselage. FAA’s Determination and Proposed Requirements of the Supplemental NPRM Certain changes discussed above expand the scope of the original NPRM; therefore, we have determined that it is E:\FR\FM\05APP1.SGM 05APP1

Discussion

    On April 14, 1997, we issued AD 97-06-13, Amendment 39-9970, Docket 
No. 97-ANE-09 (62 FR 23339, April 30, 1997), for RR Model RB211 Trent 
892, 884, 877, 875, and 892B series turbofan engines. That AD requires 
inspecting and replacing certain angle gearbox and intermediate gearbox 
hardware, and on-going repetitive inspections of the magnetic chip 
detectors on Trent 800 series engines.

Actions Since Issuing AD 97-06-13

    Since issuing AD 97-06-13, we issued a notice of proposed 
rulemaking (NPRM) on October 25, 1999, to revise the AD to include 
additional optional terminating action to the gearbox hardware 
inspections, and to extend the intervals for the magnetic chip detector 
inspections. The Trent 800 fleet has grown in size and matured in fleet 
experience. Based on the current Trent 800 fleet and the service 
experience demonstrated since we published the AD and NPRM, the 
underlying unsafe conditions no longer justify that AD.

FAA's Conclusions

    After reviewing the available data, we determined it is appropriate 
to rescind AD 97-06-13 to eliminate the mandate to perform inspections 
and hardware replacements. The inspections and hardware replacements 
are no longer required to correct an unsafe condition. Operators should 
however, incorporate those inspections and replacements into their 
normal maintenance schedules. Our determination is based on the 
following:
    We based AD 97-06-13 on a determination of unsafe conditions on a 
fleet of engines that had a total operating experience of 29,000 hours. 
Today's fleet of engines has over 1.6 million operating hours, with a 
basic in-flight shutdown rate of well below acceptable levels. Fleet 
experience does not support the original unsafe condition 
determination.
    The Civil Aviation Authority (CAA), which is the airworthiness 
authority for the United Kingdom, determined that their AD on the 
subject is no longer needed. They withdrew their AD, and they recommend 
we do likewise. Rolls-Royce plc, with CAA approval, withdrew the 
inspection service bulletins referenced in the AD. The fleet has 
completely incorporated the modifications required by AD 97-06-13, 
intended to prevent oil leaks.
    This proposed action would rescind AD 97-06-13. Rescission of AD 
97-06-13 would constitute only such action and if followed by a final 
action would not preclude the agency from issuing another action in the 
future nor would it commit the agency to any course of action in the 
future.

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 have determined that this proposed rescission would not have 
federalism implications under Executive Order 13132. This proposed 
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 that the proposed 
rescission:
    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. Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39
