D’Alessandro, Assistant Directorate Manager, Engine & Propeller Directorate, Aircraft Certification Service. [FR Doc. 2015–09816 Filed 4–28–15; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2015–0932; Directorate Identifier 2014–NM–205–AD] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747–8 series airplanes. This proposed AD was prompted by a report of improperly installed outboard stowage bin modules in the passenger compartment found during maintenance. Further investigation revealed that certain attachment bracket bushings were missing or had moved out of the holes. This proposed AD would require installing a spacer on the end of each quick-release pin that attaches the outboard stowage bin module to the lateral support tie rods of the main deck passenger compartment. We are proposing this AD to prevent detachment of the quick-release pin, which could result in separation of the lateral support tie rod and subsequent detachment of the module and consequent injuries to passengers or flightcrew. SUMMARY: We must receive comments on this proposed AD by June 15, 2015. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2015–0932; Directorate Identifier 2014– NM–205–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 23739 personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We have received a report of improperly installed outboard stowage bin modules in the passenger compartment found during maintenance. Further investigation revealed that certain attachment bracket bushings of the outboard stowage bin module were missing or had moved out of the holes, and pins were installed incorrectly. These bushings were designed to prevent disengagement of the quick release pins; however, migration of the bushings deters this. It was determined that the interference fit of the bushings in the attachment brackets was incorrect. Subsequently, installation of the quick release pins during production has caused bushings to migrate or detach. This condition, if not corrected, could result in separation of the lateral support tie rod, detachment of the outboard stowage bin module, and consequent injuries to passengers or flightcrew. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Special Attention Service Bulletin 747–25– 3649, dated July 24, 2014. The service information describes procedures for installing a spacer on the end of each quick-release pin that attaches the outboard stowage bin module to the lateral support tie rods of the main deck passenger compartment. Refer to this service information for information on the procedures and compliance times. This service information is reasonably available; see ADDRESSES for ways to access this service information. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information identified previously. Explanation of ‘‘RC’’ Steps in Service Information The FAA worked in conjunction with industry, under the Airworthiness Directives Implementation Aviation Rulemaking Committee, to enhance the AD system. One enhancement was a E:\FR\FM\29APP1.SGM 29APP1 23740 Federal Register / Vol. 80, No. 82 / Wednesday, April 29, 2015 / Proposed Rules new process for annotating which steps in the service information are required for compliance with an AD. Differentiating these steps from other tasks in the service information is expected to improve an owner’s/ operator’s understanding of crucial AD requirements and help provide consistent judgment in AD compliance. The actions specified in the service information described previously include steps that are labeled as RC (required for compliance) because these steps have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition. Steps that are identified as RC in any service information must be done to comply with the proposed AD. However, steps that are not identified as RC are recommended. Those steps that are not identified as RC may be deviated from using accepted methods in accordance with the operator’s maintenance or inspection program without obtaining approval of an alternative method of compliance (AMOC), provided the steps identified as RC can be done and the airplane can be put back in a serviceable condition. Any substitutions or changes to steps identified as RC will require approval of an AMOC. Costs of Compliance We estimate that this proposed AD affects 2 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Spacer installations .... Up to 12 work-hours X $85 per hour = Up to $1,020 ............ 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. mstockstill on DSK4VPTVN1PROD with PROPOSALS 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 VerDate Sep<11>2014 16:59 Apr 28, 2015 Jkt 235001 $0 $85 per spacer Cost on U.S. operators Up to $2,040. The Proposed Amendment (e) Unsafe Condition This AD was prompted by a report of improperly installed outboard stowage bin modules in the passenger compartment found during maintenance. Further investigation revealed that certain attachment bracket bushings were missing or had moved out of the holes. We are issuing this AD to prevent detachment of the quick-release pin, which could result in separation of the lateral support tie rod and subsequent detachment of the module and consequent injuries to passengers or flightcrew. Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: (f) Compliance Comply with this AD within the compliance times specified, unless already done. PART 39—AIRWORTHINESS DIRECTIVES (g) Installation Within 36 months after the effective date of this AD: Install a spacer on the end of each quick-release pin that attaches the outboard stowage bin module to the lateral support tie rods of the main deck passenger compartment, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 747–25– 3649, dated July 24, 2014.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2014– 0250, dated November 19, 2014 (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: There were a number of pre-MOD/SB 72– 7730 High Pressure Turbine (HPT) blade failures, with some occurring within a relatively short time. Engineering analysis carried out by RR on those occurrences indicates that certain pre-MOD/SB 72–7730 blades, Part Number (P/N) UL32958 and P/ N UL21691 (hereafter referred to as ‘affected HPT blade’), with an accumulated life of 6500 flight hours (FH) since new or more, have an increased risk of in-service failure. This condition, if not corrected, could lead to HPT blade failure, release of debris and consequent (partial or complete) loss of engine power, possibly resulting in 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–2015– 0095. 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 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 removal of the affected HPT blades. E:\FR\FM\29APP1.SGM 29APP1

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain The Boeing Company Model 747-8 series airplanes. This proposed 
AD was prompted by a report of improperly installed outboard stowage 
bin modules in the passenger compartment found during maintenance. 
Further investigation revealed that certain attachment bracket bushings 
were missing or had moved out of the holes. This proposed AD would 
require installing a spacer on the end of each quick-release pin that 
attaches the outboard stowage bin module to the lateral support tie 
rods of the main deck passenger compartment. We are proposing this AD 
to prevent detachment of the quick-release pin, which could result in 
separation of the lateral support tie rod and subsequent detachment of 
the module and consequent injuries to passengers or flightcrew.

DATES: We must receive comments on this proposed AD by June 15, 2015.

ADDRESSES: You may send comments, using the procedures found in 14 CFR

Discussion

    We have received a report of improperly installed outboard stowage 
bin modules in the passenger compartment found during maintenance. 
Further investigation revealed that certain attachment bracket bushings 
of the outboard stowage bin module were missing or had moved out of the 
holes, and pins were installed incorrectly. These bushings were 
designed to prevent disengagement of the quick release pins; however, 
migration of the bushings deters this. It was determined that the 
interference fit of the bushings in the attachment brackets was 
incorrect. Subsequently, installation of the quick release pins during 
production has caused bushings to migrate or detach. This condition, if 
not corrected, could result in separation of the lateral support tie 
rod, detachment of the outboard stowage bin module, and consequent 
injuries to passengers or flightcrew.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Service Bulletin 747-25-3649, 
dated July 24, 2014. The service information describes procedures for 
installing a spacer on the end of each quick-release pin that attaches 
the outboard stowage bin module to the lateral support tie rods of the 
main deck passenger compartment. Refer to this service information for 
information on the procedures and compliance times. This service 
information is reasonably available; see ADDRESSES for ways to access 
this service information.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information identified previously.

Explanation of ``RC'' Steps in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directives Implementation Aviation Rulemaking Committee, 
to enhance the AD system. One enhancement was a

[[Page 23740]]

new process for annotating which steps in the service information are 
required for compliance with an AD. Differentiating these steps from 
other tasks in the service information is expected to improve an 
owner's/operator's understanding of crucial AD requirements and help 
provide consistent judgment in AD compliance. The actions specified in 
the service information described previously include steps that are 
labeled as RC (required for compliance) because these steps have a 
direct effect on detecting, preventing, resolving, or eliminating an 
identified unsafe condition.
    Steps that are identified as RC in any service information must be 
done to comply with the proposed AD. However, steps that are not 
identified as RC are recommended. Those steps that are not identified 
as RC may be deviated from using accepted methods in accordance with 
the operator's maintenance or inspection program without obtaining 
approval of an alternative method of compliance (AMOC), provided the 
steps identified as RC can be done and the airplane can be put back in 
a serviceable condition. Any substitutions or changes to steps 
identified as RC will require approval of an AMOC.

Costs of Compliance

    We estimate that this proposed AD affects 2 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 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

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):

The Boeing Company: Docket No. FAA-2015-0932; Directorate Identifier 
2014-NM-205-AD.

(a) Comments Due Date

    We must receive comments by June 15, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 747-8 series 
airplanes, certificated in any category, as identified in Boeing 
Special Attention Service Bulletin 747-25-3649, dated July 24, 2014.

(d) Subject

    Air Transport Association (ATA) of America Code 25, Equipment/
Furnishings.

(e) Unsafe Condition

    This AD was prompted by a report of improperly installed 
outboard stowage bin modules in the passenger compartment found 
during maintenance. Further investigation revealed that certain 
attachment bracket bushings were missing or had moved out of the 
holes. We are issuing this AD to prevent detachment of the quick-
release pin, which could result in separation of the lateral support 
tie rod and subsequent detachment of the module and consequent 
injuries to passengers or flightcrew.

(f) Compliance

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

(g) Installation

    Within 36 months after the effective date of this AD: Install a 
spacer on the end of each quick-release pin that attaches the 
outboard stowage bin module to the lateral support tie rods of the 
main deck passenger compartment, in accordance with the 
Accomplishment Instructions of Boeing Special Attention Service 
Bulletin 747-25-3649, dated July 24, 2014.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in paragraph (i)(1) of this AD. 
Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) If any service information contains steps that are 
identified as RC (Required for

[[Page 23741]]

Compliance), those steps must be done to comply with this AD; any 
steps that are not identified as RC are recommended. Those steps 
that are not identified as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC provided the steps 
identified as RC can be done and the airplane can be put back in a 
serviceable condition. Any substitutions or changes to steps 
identified as RC require approval of an AMOC.
