We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-9 airplanes. This proposed AD was prompted by a determination that a certain bolt used on the outboard clevis of the ram air turbine (RAT) forward support fitting might not be long enough to allow for proper installation of the RAT. This proposed AD would require inspection of the forward support fitting of the RAT and replacement if cracking is found, and installation of a longer shoulder bolt. 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 
certain The Boeing Company Model 787-9 airplanes. This proposed AD was 
prompted by a determination that a certain bolt used on the outboard 
clevis of the ram air turbine (RAT) forward support fitting might not 
be long enough to allow for proper installation of the RAT. This 
proposed AD would require inspection of the forward support fitting of 
the RAT and replacement if cracking is found, and installation of a 
longer shoulder bolt. We are proposing this AD to address the unsafe 
condition on these products.

DATES: We must receive comments on this proposed AD by January 12, 
2017.

Discussion

    During production, a determination was made that the shoulder bolt 
used on the outboard clevis of the RAT forward support fitting might 
not be long enough to allow for proper installation of the RAT; 
therefore, the clevis of the joint could be clamped together, resulting 
in reduced fatigue life and possible fracture of the clevis. The RAT 
system supplies an emergency source of hydraulic power to operate the 
minimum flight controls necessary for flight, and an emergency source 
of electrical power in the case of a dual non-restartable engine loss. 
Fracture of the clevis of the forward support fitting of the RAT could 
result in the RAT departing the airplane during a dual non-restartable 
engine loss, and consequent loss of control of the airplane. The RAT 
departing the airplane could also result in injury to maintenance crews 
during periodic RAT ground tests.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin B787-81205-SB290031-00, 
Issue 001, dated March 25, 2016. The service information describes 
procedures for inspecting for cracking of the clevis of the forward 
support fitting of the RAT, installing a longer shoulder bolt, and 
replacing the forward support fitting with a new fitting if any 
cracking is found. 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-2016-
9307.

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

 replacement.
--------------------------------------------------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements of 
the forward support fitting 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

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

    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.

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-2016-9307; Directorate Identifier 
2016-NM-076-AD.

(a) Comments Due Date

    We must receive comments by January 12, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 787-9 airplanes, 
certificated in any category, as identified in Boeing Alert Service
