Airworthiness Directives; the Boeing Company Airplanes, 66859-66861 [2013-26708]

Download as PDF Federal Register / Vol. 78, No. 216 / Thursday, November 7, 2013 / Proposed Rules the licensed life for operation of a reactor and to have a mined geologic repository within 60 years following the licensed life for operation of a reactor. The proposed rule also would clarify that the generic determination applies to a license renewal for an independent spent fuel storage installation (ISFSI). The public comment period for the proposed rule and the draft generic environmental impact statement was to have expired on November 27, 2013. Due to the lapse in Federal funding and the subsequent shutdown of the NRC, and requests from members of the public to extend the comment period, the NRC has decided to extend the comment period until December 20, 2013. Dated at Rockville, Maryland, this 1st day of November 2013. For the Nuclear Regulatory Commission. Annette Vietti-Cook, Secretary of the Commission.

Discussion We have received reports of bearing damage at the TE flap support rib assemblies in flap positions 1, 2, 4, 5, 7, and 8. Bearing damage in the TE flap support rib assembly is caused by the use of mallets during the installation of the shaft on the TE flap support rib assembly when TE flap support bearings without a roller retention feature are installed. This method of installation may compromise bearings without a roller retention feature. Damaged TE flap support bearings can lead to damage to the TE rotary actuators and other TE flap support rib parts, which could result in a dual flap drive system disconnect in both TE flap rotary actuators, and a possible flap aerodynamic blowback with loss of controllability of the airplane. Relevant Service Information We reviewed Boeing Alert Service Bulletin 767–27A0227, dated February 12, 2013. For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for Docket No. FAA–2013–0869. 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, except as discussed under ‘‘Differences Between the Proposed AD and the Service Information.’’ The phrase ‘‘related investigative actions’’ is used in this proposed AD. ‘‘Related investigative actions’’ are follow-on actions that: (1) Are related to the primary actions, and (2) further E:\FR\FM\07NOP1.SGM 07NOP1 66860 Federal Register / Vol. 78, No. 216 / Thursday, November 7, 2013 / Proposed Rules investigate the nature of any condition found. Related investigative actions in an AD could include, for example, inspections. In addition, the phrase ‘‘corrective actions’’ is used in this proposed AD. ‘‘Corrective actions’’ are actions that correct or address any condition found. Corrective actions in an AD could include, for example, repairs. Costs of Compliance We estimate that this proposed AD affects 45 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Inspection ...................... Up to 40 work-hours × $85 per hour = Up to $3,400. $0 Up to $3,400 ................ We estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection. We have no way of Cost on U.S. operators Up to $153,000. determining the number of aircraft that might need these replacements: ON-CONDITION COSTS Action Bearing replacement and functional test. Labor cost Parts cost Up to 24 work-hours × $85 per hour = Up to $2,040 ... Up to $5,936 ...................... According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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. tkelley on DSK3SPTVN1PROD with PROPOSALS Regulatory Findings 16:14 Nov 06, 2013 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

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 767 airplanes. This proposed AD was 
prompted by reports of bearing damage at certain trailing edge (TE) 
flap support rib assemblies. This proposed AD would require inspecting 
certain TE flap support rib assemblies to determine if the bearings 
have a roller retention feature, and performing corrective actions if 
necessary; and inspecting for bearing damage of each pair of removed 
bearings, and performing related investigative and corrective actions 
if necessary. We are proposing this AD to detect and correct damage to 
the TE flap support bearings, which can result in damage to the TE 
rotary actuators and consequent dual flap drive system disconnect in 
both TE flap rotary actuators, and a possible flap aerodynamic blowback 
with loss of controllability of the airplane.

DATES: We must receive comments on this proposed AD by December 23, 
2013.

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-2013-0869; 
Directorate Identifier 2013-NM-063-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 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 reports of bearing damage at the TE flap support 
rib assemblies in flap positions 1, 2, 4, 5, 7, and 8. Bearing damage 
in the TE flap support rib assembly is caused by the use of mallets 
during the installation of the shaft on the TE flap support rib 
assembly when TE flap support bearings without a roller retention 
feature are installed. This method of installation may compromise 
bearings without a roller retention feature. Damaged TE flap support 
bearings can lead to damage to the TE rotary actuators and other TE 
flap support rib parts, which could result in a dual flap drive system 
disconnect in both TE flap rotary actuators, and a possible flap 
aerodynamic blowback with loss of controllability of the airplane.

Relevant Service Information

    We reviewed Boeing Alert Service Bulletin 767-27A0227, dated 
February 12, 2013. For information on the procedures and compliance 
times, see this service information at https://www.regulations.gov by 
searching for Docket No. FAA-2013-0869.

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, except as discussed 
under ``Differences Between the Proposed AD and the Service 
Information.''
    The phrase ``related investigative actions'' is used in this 
proposed AD. ``Related investigative actions'' are follow-on actions 
that: (1) Are related to the primary actions, and (2) further

[[Page 66860]]

investigate the nature of any condition found. Related investigative 
actions in an AD could include, for example, inspections.
    In addition, the phrase ``corrective actions'' is used in this 
proposed AD. ``Corrective actions'' are actions that correct or address 
any condition found. Corrective actions in an AD could include, for 
example, repairs.

Costs of Compliance

    We estimate that this proposed AD affects 45 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

                                  $3,400.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of aircraft that might need 
these replacements:

                                               On-Condition Costs

 test.                                per hour = Up to $2,040.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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 
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

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

The Boeing Company: Docket No. FAA-2013-0869; Directorate Identifier 
2013-NM-063-AD.

(a) Comments Due Date

    We must receive comments by December 23, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 767-200, -300, -
300F, and -400ER series airplanes, certificated in any category, as 
identified in Boeing Alert Service Bulletin 767-27A0227, dated 
February 12, 2013.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 27, Flight controls.

(e) Unsafe Condition

    This AD was prompted by reports of bearing damage at certain 
trailing edge (TE) flap support rib assemblies. We are issuing this 
AD to detect and correct damage to the TE flap support bearings, 
which can result in damage to the TE rotary actuators and consequent 
dual flap drive system disconnect in both TE flap rotary actuators, 
and a possible flap aerodynamic blowback with loss of 
controllability of the airplane.

(f) Compliance

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

(g) Bearing Inspection To Determine Roller Retention Feature and 
Corrective Actions

    Except as provided by paragraph (i) of this AD, at the 
applicable time specified in paragraph 1.E., ``Compliance,'' of 
Boeing Alert Service Bulletin 767-27A0227, dated February 12, 2013: 
Do a general visual inspection of both bearings at the TE flap 
support rib assembly in flap positions 1, 2, 7, and 8 to determine 
if the bearings have a roller retention feature; and do all 
applicable corrective actions; in accordance with the Accomplishment 
Instructions of Boeing Alert

[[Page 66861]]

Service Bulletin 767-27A0227, dated February 12, 2013. Do all 
applicable corrective actions before further flight.

(h) Bearing Inspection for Damage, Related Investigative Actions, and 
Corrective Actions

    For each pair of bearings removed as required by paragraph (g) 
of this AD: At the applicable time specified in paragraph 1.E., 
``Compliance,'' of Boeing Alert Service Bulletin 767-27A0227, dated 
February 12, 2013: Do a general visual inspection for bearing damage 
of the bearings; and do all applicable related investigative and 
corrective actions; in accordance with the Accomplishment 
Instructions of Boeing Alert Service Bulletin 767-27A0227, dated 
February 12, 2013. Do all applicable related investigative and 
corrective actions before further flight.

(i) Exception to Compliance Time

    Where paragraph 1.E., ``Compliance,'' of Boeing Alert Service 
Bulletin 767-27A0227, dated February 12, 2013, specifies a 
compliance time ``after the original issue date of this service 
bulletin,'' this AD requires compliance within the specified 
compliance time ``after the effective date of this AD.''

(j) Credit for Previous Actions Accomplished in Accordance With 
Previous Service Information

    This paragraph provides credit for the actions specified in 
paragraphs (g) and (h) of this AD, if those actions were performed 
before the effective date of this AD using of Boeing Alert Service 
Bulletin 767-27A0222, dated June 24, 2010, which is not incorporated 
by reference in this AD.

(k) 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 the Related Information 
section 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) An AMOC that provides an acceptable level of safety may be 
used for any repair required by this AD if it is approved by the 
Boeing Commercial Airplanes Organization Designation Authorization 
(ODA) that has been authorized by the Manager, Seattle ACO, to make 
those findings. For a repair method to be approved, the repair must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
