Airworthiness Directives; Rolls-Royce (1971) Limited, Bristol Engine Division Turbojet Engines, 12255-12256 [2013-04103]

Download as PDF Federal Register / Vol. 78, No. 36 / Friday, February 22, 2013 / Proposed Rules (a) To what extent do you believe the current rotorcraft certification standards need to be amended to remain relevant over the next 20 years, given the rapid pace of advances in technology? (b) Should the current rotorcraft certification standards be completely changed, or are weight and number of passengers still relevant for determining certification? (c) If you believe certification should continue to be based on weight and number of passengers, to what extent should the existing standards be updated, and how? (d) As revisions to regulatory certification standards would require participation in a rulemaking committee over a substantial period of time, to what extent would you be willing to participate? As a convenience, these questions are available for submission in the same format as above at the following Web site link: https://www.faa.gov/aircraft/ air_cert/design_approvals/rotorcraft/ comm. If the FAA decides to have further rulemaking discussions on these issues, we will issue a document, giving the public another opportunity to comment. Issued in Fort Worth, TX, on February 8, 2013.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0243 (Correction: November 13, 2012), dated November 12, 2012, a Mandatory Continuing Airworthiness Information (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: A review, carried out by Rolls-Royce, of the lives of critical parts of the Viper Mk. 601– 22 engine, has resulted in reduced cyclic life limits for certain critical parts. Operation of critical parts beyond these reduced cyclic life limits may result in part failure, possibly resulting in the release of high-energy debris, which may cause damage to the aeroplane and/or injury to the occupants. For the reasons described above, this AD requires implementation of the reduced cyclic life limits for the affected critical parts, i.e., replacement of each part before the applicable reduced life limit is exceeded, and replacement of those critical parts that have already exceeded the reduced cyclic life limits. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information RR Alert Service Bulletin 72–A206, dated November, 2012.

We are proposing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This proposed AD would require reducing the life of certain critical parts. under the criteria of the Regulatory Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. (f) Alternative Methods of Compliance (AMOCs) The Manager, Engine Certification Office, FAA, may approve AMOCs for this AD. Use the procedures found in 14 CFR 39.19 to make your request. List of Subjects in 14 CFR Part 39 Costs of Compliance We estimate that this proposed AD affects 32 engines installed on airplanes of U.S. registry. We also estimate that it would take 0 hours per product to comply with this proposed AD. The average labor rate is $85 per hour. We are not requiring parts replacement, so parts cost is $0. We estimate the cost of the proposed AD on U.S. operators to be $0.

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 AD will not have federalism implications under Executive Order 13132. This AD will 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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0243 (Correction: November 13, 2012), 
dated November 12, 2012, a Mandatory Continuing Airworthiness 
Information (referred to hereinafter as ``the MCAI''), to correct an 
unsafe condition for the specified products. The MCAI states:

    A review, carried out by Rolls-Royce, of the lives of critical 
parts of the Viper Mk. 601-22 engine, has resulted in reduced cyclic 
life limits for certain critical parts.
    Operation of critical parts beyond these reduced cyclic life 
limits may result in part failure, possibly resulting in the release 
of high-energy debris, which may cause damage to the aeroplane and/
or injury to the occupants.
    For the reasons described above, this AD requires implementation 
of the reduced cyclic life limits for the affected critical parts, 
i.e., replacement of each part before the applicable reduced life 
limit is exceeded, and replacement of those critical parts that have 
already exceeded the reduced cyclic life limits.

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    RR Alert Service Bulletin 72-A206, dated November, 2012.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of the 
United Kingdom and is approved for operation in the United States. 
Pursuant to our bilateral agreement with the European

[[Page 12256]]

Community, EASA has notified us of the unsafe condition described in 
the MCAI and service information referenced above. We are proposing 
this AD because we evaluated all information provided by EASA and 
determined the unsafe condition exists and is likely to exist or 
develop on other products of the same type design. This proposed AD 
would require reducing the life of certain critical parts.

Costs of Compliance

    We estimate that this proposed AD affects 32 engines installed on 
airplanes of U.S. registry. We also estimate that it would take 0 hours 
per product to comply with this proposed AD. The average labor rate is 
$85 per hour. We are not requiring parts replacement, so parts cost is 
$0. We estimate the cost of the proposed AD on U.S. operators to be $0.

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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 AD:
    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 AD and placed it in the AD docket.
