Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2017– 0010, dated January 16, 2017 (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Based on revised stress analysis and life calculation, Rolls-Royce Deutschland (RRD) determined new provisional life limits for HPC stage 12 rotor disc Part Number (P/N) JR18449, reducing the maximum approved life limit defined in the Tay 620–15 and Tay 620–15/20 engine Time Limits Manual (TLM), Chapter 05–10–01, Task 05–10–01– 800–000, currently at revision dated 15 September 2014. Failure to replace a HPC stage 12 rotor disc P/N JR18449, before exceeding the thresholds defined by this AD, could lead to an uncontained HPC stage 12 rotor disc failure, possibly resulting in damage to, and/or reduced control of, the aeroplane. You may obtain further information by examining the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0140. Related Service Information RRD has issued Alert NonModification Service Bulletin (NMSB) TAY–72–A1813, dated October 11, 2016. The Alert NMSB provides instructions to determine or re-calculate the consumed and remaining service life. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of Germany, and is approved for operation in the United States. Pursuant to our bilateral agreement with the European 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 maximum approved life limit for HPC stage 12 rotor disk, part number JR18449. Costs of Compliance We estimate that this proposed AD affects 25 engines installed on airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Labor cost Pro-rated life ................................................... mstockstill on DSK30JT082PROD with PROPOSALS Action 1 work-hour × $85 per hour = $85 ................. 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: VerDate Sep<11>2014 17:53 May 25, 2017 Jkt 241001 Parts cost 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: PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 $3,858 Cost per product $3,943 Cost on U.S. operators $98,575 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 E:\FR\FM\26MYP1.SGM 26MYP1 Federal Register / Vol. 82, No. 101 / Friday, May 26, 2017 / Proposed Rules 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. (e) Reason The Proposed Amendment Regulatory Findings PART 39—AIRWORTHINESS DIRECTIVES 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 to the extent that it justifies making a regulatory distinction, 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. Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: This AD was prompted by RRD recalculating the life limit for HPC stage 12 rotor disk P/N JR18449. We are issuing this AD to prevent failure of the HPC stage 12 rotor disk, uncontained HPC stage 12 rotor disk release, damage to the engine, and damage to the airplane. (f) Compliance 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 24259 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ Rolls-Royce Deutschland Ltd & Co KG: Docket No. FAA–2017–0140; Directorate Identifier 2017–NE–05–AD.

Discussion On May 25, 2016, we issued AD 2016–11–20, Amendment 39–18547 (81 FR 37492, June 10, 2016), (‘‘AD 2016– 11–20’’), for B/E Aerospace Protective Breathing Equipment (PBE), part number (P/N) 119003–11, that is installed on airplanes. AD 2016–11–20 requires replacing all PBE, P/N 119003– 11, with PBE, P/N 119003–21. AD 2016– 11–20 resulted from a report of a PBE unit, P/N 119003–11, catching fire upon activation by a crewmember. We issued AD 2016–11–20 to correct the unsafe condition on these products. Actions Since AD 2016–11–20 Was Issued Since we issued AD 2016–11–20, we received a report that a mechanic incurred a minor injury when he activated the affected PBE unit as part of the disposal process. The igniter candle in the PBE supplies the user with oxygen during the first 20 seconds after activation. For PBE units with a serial number within the serial number range identified in this proposed AD, the candle tube material was determined to have a low yield strength. This can result in inadequate retention of the end fitting during activation, and the candle may eject from the PBE as a high speed projectile.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2017-0010, dated January 16, 2017 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    Based on revised stress analysis and life calculation, Rolls-
Royce Deutschland (RRD) determined new provisional life limits for 
HPC stage 12 rotor disc Part Number (P/N) JR18449, reducing the 
maximum approved life limit defined in the Tay 620-15 and Tay 620-
15/20 engine Time Limits Manual (TLM), Chapter 05-10-01, Task 05-10-
01-800-000, currently at revision dated 15 September 2014. Failure 
to replace a HPC stage 12 rotor disc P/N JR18449, before exceeding 
the thresholds defined by this AD, could lead to an uncontained HPC 
stage 12 rotor disc failure, possibly resulting in damage to, and/or 
reduced control of, the aeroplane.

    You may obtain further information by examining the MCAI in the AD 
docket on the Internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2017-0140.

Related Service Information

    RRD has issued Alert Non-Modification Service Bulletin (NMSB) TAY-
72-A1813, dated October 11, 2016. The Alert NMSB provides instructions 
to determine or re-calculate the consumed and remaining service life. 
This service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of 
Germany, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the European 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 
maximum approved life limit for HPC stage 12 rotor disk, part number 
JR18449.

Costs of Compliance

    We estimate that this proposed AD affects 25 engines installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

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

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

[[Page 24259]]

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 to the extent 
that it justifies making a regulatory distinction, 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.

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

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Rolls-Royce Deutschland Ltd & Co KG: Docket No. FAA-2017-0140; 
Directorate Identifier 2017-NE-05-AD.

(a) Comments Due Date

    We must receive comments by July 10, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) 
model Tay 620-15 turbofan engines with high-pressure compressor 
(HPC) modules M03100AA, or M03100AB, or M03100AC and HPC stage 12 
rotor disk part number (P/N) JR18449 installed.

(d) Subject

    Joint Aircraft System Component (JASC) 7230, Turbine Engine 
Compressor Section.

(e) Reason

    This AD was prompted by RRD recalculating the life limit for HPC 
stage 12 rotor disk P/N JR18449. We are issuing this AD to prevent 
failure of the HPC stage 12 rotor disk, uncontained HPC stage 12 
rotor disk release, damage to the engine, and damage to the 
airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    (1) Within 30 days after the effective date of this AD, 
determine whether the HPC stage 12 rotor disk has operated in both 
flight profiles A and B. If the rotor disk was operated, or is 
operating, in both flight profiles A and B, re-calculate the 
consumed cyclic life using 16,700 flight cycles (FC) as the maximum 
approved life limit for flight profile B.
    (2) After the effective date of this AD, the maximum approved 
life limit for affected rotor disks operating in flight profile B is 
16,700 FC. Calculate the consumed cyclic life accumulated since new 
using 16,700 FC as the maximum approved life limit for flight 
profile B.
    (3) For those engines operating in flight profile B with an HPC 
stage 12 rotor disk P/N JR18449 installed, that do not have an 
engine shop visit after the effective date of this AD before the re-
calculated consumed cyclic life of the HPC stage 12 disk exceeds 
16,700 FC, remove the affected rotor disk from service before the 
re-calculated consumed cyclic life exceeds the threshold(s) defined 
in Figure 1 to paragraph (g) of this AD.
