We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 787-8 and 787-9 airplanes. This proposed AD was prompted by a report that the Parking Brake and Alternate Pitch Trim Module (PBM) may unintentionally disengage, fail to set, fail to release, or become jammed. This proposed AD would require replacing the PBM and doing a PBM installation test. We are proposing this AD to address the unsafe condition on these products.

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 all 
The Boeing Company Model 787-8 and 787-9 airplanes. This proposed AD 
was prompted by a report that the Parking Brake and Alternate Pitch 
Trim Module (PBM) may unintentionally disengage, fail to set, fail to 
release, or become jammed. This proposed AD would require replacing the 
PBM and doing a PBM installation test. We are proposing this AD to 
address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2017-0553; 
Directorate Identifier 2016-NM-208-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 http://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 a report indicating that the current PBM may 
unintentionally disengage, fail to set, fail to release, or become 
jammed. The procedure for releasing the parking brake requires 
depressing the brake pedals. The current PBM can be disengaged without 
depressing the brake pedals. Operators may experience error messages, 
jammed PBM solenoid, unintended parking brake release, and the 
inability to set or release the parking brake. An unintended parking 
brake release could result in damage to the airplane and be a hazard to 
persons or property on the ground.

[[Page 26873]]

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Service Bulletin B787-81205-SB320028-00, Issue 
001, dated October 31, 2016. The service information describes 
procedures for replacing the PBM and doing a PBM installation test. 
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 previously. For information on the 
procedures and compliance times, see this service information at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0553.
    The phrase ``corrective actions'' is used in this proposed AD. 
Corrective actions correct or address any condition found. Corrective 
actions in an AD could include, for example, repairs.

Differences Between This Proposed AD and the Service Information

    The effectivity of Boeing Service Bulletin B787-81205-SB320028-00, 
Issue 001, dated October 31, 2016, is limited to certain The Boeing 
Company Model 787-8 and 787-9 airplanes. However, the applicability of 
this proposed AD includes all Model 787-8 and 787-9 airplanes. Because 
the affected parts are rotable parts, we have determined that these 
parts could later be installed on airplanes that were initially 
delivered with acceptable parts, thereby subjecting those airplanes to 
the unsafe condition. This difference has been coordinated with Boeing.

Costs of Compliance

    We estimate that this proposed AD affects 68 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                          Cost per
            Action                   Labor cost         Parts cost         product       Cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
Inspection...................  1 work-hour x $85 per              $0  Up to $85.......  Up to $5,780.
                                hour = $85.
PBM replacement and test.....  4 work-hours x $85              9,655  9,995...........  679,660.
                                per hour = $340.
----------------------------------------------------------------------------------------------------------------

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

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-2017-0553; Directorate Identifier 
2016-NM-208-AD.

(a) Comments Due Date

    We must receive comments by July 27, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model 787-8 and 787-9 
airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 32; Landing 
gear.

(e) Unsafe Condition

    This AD was prompted by a report that the Parking Brake and 
Alternate Pitch Trim Module (PBM) may unintentionally disengage, 
fail to set, fail to release, or become jammed. We are issuing this 
AD to prevent an unintended parking brake release, which could 
result in damage to the airplane and be a hazard to persons or 
property on the ground.

(f) Compliance

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

(g) Inspection and Replacement

    For airplanes on which the original airworthiness certificate or 
the original export certificate of airworthiness was issued on or 
before the effective date of this AD: Within 60 months after the 
effective date of this AD, inspect the PBM to determine the part 
number. A review of airplane maintenance or delivery records is 
acceptable in lieu of the inspection if the part number

[[Page 26874]]

of the PBM can be conclusively determined from that review.
    (1) If the PBM is Rockwell Collins part number (P/N) 4260-0037-
5: No further action is required by this paragraph.
    (2) If the PBM is Rockwell Collins P/N 4260-0037-3 or -4: Within 
60 months after the effective date of this AD, install PBM P/N 4260-
0037-5, do the PBM installation test, and do all applicable 
corrective actions, in accordance with the Accomplishment 
Instructions of Boeing Service Bulletin B787-81205-SB320028-00, 
Issue 001, dated October 31, 2016. Do all applicable corrective 
actions before further flight.

(h) Parts Installation Prohibition

    As of the effective date of this AD, no person may install on 
any airplane, a PBM having Rockwell Collins P/N 4260-0037-3 or -4.

(i) 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 (j)(1) of this AD. 
Information may be emailed to: [email protected].
    (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, modification, or alteration 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. To be approved, the 
repair method, modification deviation, or alteration deviation 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 
(i)(4)(i) and (i)(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. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. 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.
