Airworthiness Directives; The Boeing Company, 45070-45072 [2016-16323]

Download as PDF 45070 Proposed Rules Federal Register Vol. 81, No. 133 Tuesday, July 12, 2016 This section of the FEDERAL REGISTER contains notices to the public of the proposed issuance of rules and regulations. The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2016–7419; Directorate Identifier 2015–NM–189–AD] RIN 2120–AA64 Airworthiness Directives; The Boeing Company 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 787–8 and 787–9 airplanes. This proposed AD was prompted by a report that some inboard and outboard trailing edge flap rotary actuators may have been assembled with an incorrect no-back brake rotorstator stack sequence during manufacturing. This proposed AD would require an inspection of the inboard and outboard flap trailing edge rotary actuator for any discrepant rotary actuator. For discrepant rotary actuators, this proposed AD would require replacing the rotary actuator, or determining the flight cycles on the rotary actuator and doing related investigative and corrective actions if necessary. We are proposing this AD to detect and replace rotary actuators having incorrect assembly, which could cause accelerated unit wear that will eventually reduce braking performance. This degradation could lead to loss of no-back brake function and reduced controllability of the airplane. DATES: We must receive comments on this proposed AD by August 26, 2016. 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– 2016–7419; Directorate Identifier 2015– PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 NM–189–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 received a report that some inboard and outboard trailing edge flap rotary actuators may have been assembled with an incorrect no-back brake rotor-stator stack sequence during manufacturing. This condition, if not corrected, could result in accelerated unit wear that will eventually reduce braking performance. This degradation could lead to loss of no-back brake function and reduced controllability of the airplane. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin B787–81205–SB270032–00, Issue 001, dated November 3, 2015. The service information describes procedures for an inspection of the inboard and outboard flap rotary actuator for any discrepant rotary actuator, and procedures for replacing the rotary actuator, or determining the flight cycles on the rotary actuator and applicable related investigative and corrective actions. 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 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 described E:\FR\FM\12JYP1.SGM 12JYP1 45071 Federal Register / Vol. 81, No. 133 / Tuesday, July 12, 2016 / Proposed Rules previously. For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for and locating Docket No. FAA–2016– 7419. ‘‘Related investigative actions’’ are follow-on actions that (1) are related to the primary action, and (2) are actions that further investigate the nature of any condition found. Related investigative actions in an AD could include, for example, inspections. ‘‘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 5 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 Cost on U.S. operators Inspection ........................................................ 1 work-hour × $85 per hour = $85 ................. $0 $85 $425 We estimate the following costs to do any necessary on-condition actions 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 this replacement: ON-CONDITION COSTS Action Labor cost Check to determine flight cycles on the rotary actuator ................... Functional test ................................................................................... Replacement ...................................................................................... 1 work-hour × $85 per hour = $85 .......... 2 work-hours × $85 per hour = $170 ...... 2 work-hours × $85 per hour = $170 ...... 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 DSK3G9T082PROD 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: 18:07 Jul 11, 2016 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 Regulatory Findings VerDate Sep<11>2014 (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.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. AGENCY: We are revising an earlier proposed airworthiness directive (AD) for certain Saab AB, Saab Aeronautics Model 340A (SAAB/SF340A) and SAAB 340B airplanes. The NPRM proposed to supersede AD 2012–24–06. AD 2012– 24–06 currently requires replacing the stall warning computer (SWC) with a new SWC that provides an artificial stall warning in icing conditions, and modifying the airplane for the replacement of the SWC. The NPRM was prompted by a determination that airplanes with certain modifications were excluded from the applicability in AD 2012–24–06, and are affected by the identified unsafe condition; and the SWC required by AD 2012–24–06 contained erroneous logic. This action revises the NPRM by reducing the compliance time for replacing the SWCs. We are proposing this supplemental NPRM (SNPRM) to prevent natural stall events during operation in icing conditions, which could result in loss of control of the airplane. Since this compliance time reduction imposes an additional burden to operators, we are reopening the comment period to allow the public the SUMMARY: PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 chance to comment on these proposed changes.

Airworthiness Directives; The Boeing Company

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 787-8 and 787-9 airplanes. This 
proposed AD was prompted by a report that some inboard and outboard 
trailing edge flap rotary actuators may have been assembled with an 
incorrect no-back brake rotor-stator stack sequence during 
manufacturing. This proposed AD would require an inspection of the 
inboard and outboard flap trailing edge rotary actuator for any 
discrepant rotary actuator. For discrepant rotary actuators, this 
proposed AD would require replacing the rotary actuator, or determining 
the flight cycles on the rotary actuator and doing related 
investigative and corrective actions if necessary. We are proposing 
this AD to detect and replace rotary actuators having incorrect 
assembly, which could cause accelerated unit wear that will eventually 
reduce braking performance. This degradation could lead to loss of no-
back brake function and reduced controllability of the airplane.

DATES: We must receive comments on this proposed AD by August 26, 2016.

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

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-2016-7419; 
Directorate Identifier 2015-NM-189-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 received a report that some inboard and outboard trailing edge 
flap rotary actuators may have been assembled with an incorrect no-back 
brake rotor-stator stack sequence during manufacturing. This condition, 
if not corrected, could result in accelerated unit wear that will 
eventually reduce braking performance. This degradation could lead to 
loss of no-back brake function and reduced controllability of the 
airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin B787-81205-SB270032-00, 
Issue 001, dated November 3, 2015. The service information describes 
procedures for an inspection of the inboard and outboard flap rotary 
actuator for any discrepant rotary actuator, and procedures for 
replacing the rotary actuator, or determining the flight cycles on the 
rotary actuator and applicable related investigative and corrective 
actions. 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

    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 described

[[Page 45071]]

previously. For information on the procedures and compliance times, see 
this service information at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2016-7419.
    ``Related investigative actions'' are follow-on actions that (1) 
are related to the primary action, and (2) are actions that further 
investigate the nature of any condition found. Related investigative 
actions in an AD could include, for example, inspections.
    ``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 5 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

    We estimate the following costs to do any necessary on-condition 
actions 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 this replacement:

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

    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

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-2016-7419; Directorate Identifier 
2015-NM-189-AD.

(a) Comments Due Date

    We must receive comments by August 26, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 787-8 and 787-9 
airplanes, certificated in any category, as identified in Boeing 
Alert Service Bulletin B787-81205-SB270032-00, Issue 001, dated 
November 3, 2015.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Control Systems.

(e) Unsafe Condition

    This AD was prompted by a report that some inboard and outboard 
trailing edge flap rotary actuators may have been assembled with an 
incorrect no-back brake rotor-stator stack sequence during 
manufacturing. We are issuing this AD to detect and replace rotary 
actuators having incorrect assembly, which could cause accelerated 
unit wear that will eventually reduce braking performance. This 
degradation could lead to loss of no-back brake function and reduced 
controllability of the airplane.

(f) Compliance

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

(g) Inspection and Other Actions

    Within 60 months after the effective date of this AD, do an 
inspection of the inboard and outboard trailing edge flap rotary 
actuator for any discrepant rotary actuator, in accordance with the 
Accomplishment

[[Page 45072]]

Instructions of Boeing Alert Service Bulletin B787-81205-SB270032-
00, Issue 001, dated November 3, 2015. If any discrepant rotary 
actuator is found, within 60 months after the effective date of this 
AD, do the actions specified in paragraph (g)(1) or (g)(2) of this 
AD, in accordance with the Accomplishment Instructions of Boeing 
Alert Service Bulletin B787-81205-SB270032-00, Issue 001, dated 
November 3, 2015.
    (1) Replace the discrepant rotary actuator.
    (2) Check the maintenance records to determine the flight cycles 
of each discrepant rotary actuator and, within 60 months after the 
effective date of this AD, do all applicable related investigative 
and corrective actions.

(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) 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.
    (4) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(h)(4)(i) and (h)(4)(ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. An AMOC is required for any deviations to RC steps, 
including substeps and identified figures.
    (ii) Steps not labeled 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 RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
