Download as PDF Federal Register / Vol. 77, No. 34 / Tuesday, February 21, 2012 / 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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. srobinson on DSK4SPTVN1PROD with PROPOSALS § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): Honeywell International Inc.

Since we issued AD 2009–07–01 (74 FR 12086, March 23, 2009), RRD has revised the approved published life limits of these HP turbine stage 1 discs to the same or higher limits as originally certified. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive Cancellation Notice 2007–0152–CN, dated December 22, 2011. EASA stated in that Cancellation Notice that they have approved published life limits for the affected parts that are increased to the same or higher value as originally certified. We have evaluated the information provided by RRD and EASA and have determined that an unsafe condition no longer exists in these HP turbine stage 1 and stage 2 discs.

Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. The existing AD currently requires revising the airworthiness limitations section (ALS) of the instructions for continued airworthiness for certain airplanes, and the FAAapproved maintenance program for certain other airplanes, to incorporate new limitations for fuel tank systems. Since we issued that AD, Fokker Services B.V. has revised a Fokker 70/ 100 maintenance review board (MRB) document with revised limitations, tasks, thresholds, and intervals. This proposed AD would revise the maintenance program to incorporate the limitations, tasks, thresholds, and intervals specified in that Fokker MRB document. We are proposing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

Discussion On July 9, 2004, we issued AD 2004– 15–08, Amendment 39–13742 (69 FR 44586, July 27, 2004). This AD required actions intended to address an unsafe condition on the products listed above. Since we issued AD 2004–15–08, Amendment 39–13742 (69 FR 44586, July 27, 2004): The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2011– 0157, dated August 25, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Fokker Services have published issue 8 of report SE–623 dated 17 March 2011, which is part of the Airworthiness Limitations Section of the Instructions for Continued Airworthiness, referred to in Section 06, Appendix 1, of the Fokker 70/100 Maintenance Review Board (MRB) document. The complete Airworthiness Limitations Section currently consists of: —Certification Maintenance Requirements (CMRs)—report SE–473, issue 8, —Airworthiness Limitation Items (ALIs) and Safe Life Items (SLIs)—report SE–623, issue 8, —Fuel ALIs and Critical Design Configuration Control Limitations (CDCCLs)—report SE–672, issue 2. The instructions contained in those reports have been identified as mandatory actions for continued airworthiness. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2011–0046, which is superseded, and requires the implementation of the inspections and limitations as specified in the Airworthiness Limitation Section of the Instructions for Continued Airworthiness, referred to in Section 06, Appendix 1 of the Fokker 70/100 MRB document, reports SE– 473, SE–623 and SE–672 at the abovementioned issues. You may obtain further information by examining the MCAI in the AD docket. The FAA has examined the underlying safety issues involved in fuel tank explosions on several large transport airplanes, including the adequacy of existing regulations, the service history of airplanes subject to those regulations, and existing maintenance practices for fuel tank E:\FR\FM\21FEP1.SGM 21FEP1

complete Privacy Act Statement in the Federal Register published on

Discussion

    On March 17, 2009, we issued AD 2009-07-01 (74 FR 12086, March 23, 
2009). That AD requires reducing the published life limits of BR700-715 
turbofan engine HP turbine stage 1 discs, P/Ns BRH20130 and BRH20131, 
and HP turbine stage 2 discs, P/Ns BRH19423 and BRH19427.
    Since we issued AD 2009-07-01 (74 FR 12086, March 23, 2009), RRD 
has revised the approved published life limits of these HP turbine 
stage 1 discs to the same or higher limits as originally certified. The 
European Aviation Safety Agency (EASA), which is the Technical Agent 
for the Member States of the European Community, has issued EASA 
Airworthiness Directive Cancellation Notice 2007-0152-CN, dated 
December 22, 2011. EASA stated in that Cancellation Notice that they 
have approved published life limits for the affected parts that are 
increased to the same or higher value as originally certified. We have 
evaluated the information provided by RRD and EASA and have determined 
that an unsafe condition no longer exists in these HP turbine stage 1 
and stage 2 discs.

FAA's Determination and Requirements of This Proposed AD Rescission

    We are proposing this AD rescission of AD 2009-07-01 (74 FR 12086, 
March 23, 2009) because we evaluated all information and determined 
that allowing the increase in the published part life limits is 
acceptable. This proposed AD would rescind AD 2009-07-01.

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 a practice, method, or 
procedure necessary for safety in air commerce.

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
