Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 767-300 and 767-300F series airplanes. This AD 
was prompted by reports of malfunctions in the flight deck display 
units, which resulted in blanking, blurring, or loss of color on the 
display. This AD requires modification and installation of components 
in the main equipment center. For certain other airplanes this AD 
requires modification, replacement, and installation of flight deck air 
relief system (FDARS) components. We are issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective February 21, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 21, 
2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 by adding an AD that would apply to certain The 
Boeing Company Model 767-300 and 767-300F series airplanes. The SNPRM 
published in the Federal Register on May 27, 2016 (81 FR 33612) (``the 
SNPRM''). We preceded the SNPRM with a notice of proposed rulemaking 
(NPRM) that published in the Federal Register on September 25, 2013 (78 
FR 58970) (``the NPRM''). The NPRM proposed to require modification and 
installation of components in the main equipment center. For certain 
other airplanes, the NPRM proposed to require modification, 
replacement, and installation of FDARS components. The NPRM was 
prompted by reports of malfunctions in the flight deck display units, 
which resulted in blanking, blurring, or loss of color on the display. 
The SNPRM proposed to revise the applicability, add certain 
modifications, and clarify certain requirements. We are issuing this AD 
to prevent malfunctions of the flight deck display units, which could 
affect the ability of the flight crew to read the displays for airplane 
attitude, altitude, or airspeed, and consequently reduce the ability of 
the flight crew to maintain control of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the SNPRM and 
the FAA's response to each comment.

Support for the SNPRM

    The Air Line Pilots Association, International supported the intent 
of the SNPRM.

Effect of Winglets on Accomplishment of the Specified Actions

    Aviation Partners Boeing stated that the installation of winglets 
per Supplemental Type Certificate (STC) ST01920SE does not affect the 
accomplishment of the manufacturer's service instructions.
    We agree with the commenter that STC ST01920SE does not affect the 
accomplishment of the manufacturer's service instructions. Therefore, 
the installation of STC ST01920SE does not affect the ability to 
accomplish the actions required by this AD. We have not changed this 
final rule in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed, except for minor editorial changes. We have 
determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed the following service information.
    <bullet> Boeing Service Bulletin 767-21-0235, dated October 8, 
2009; and Revision 1, dated July 29, 2011 (``SB 767-21-0235, R1''). The 
service information describes procedures for a relay installation and 
related wiring changes (which change (modify) the 3-way valve control 
logic for the cooling system for the flight deck display equipment on 
freighter airplanes).

[[Page 4779]]

    <bullet> Boeing Service Bulletin 767-21-0244, Revision 1, dated 
March 8, 2010 (``SB 767-27-0244, R1''). The service information 
describes procedures for changing (modifying) the 3-way valve control 
logic and installing a cooling system for the flight deck display 
equipment.
    <bullet> Boeing Alert Service Bulletin 767-21A0245, Revision 2, 
dated September 27, 2013 (``ASB 767-21A0245, R2''); and Boeing Alert 
Service Bulletin 767-21A0247, Revision 1, dated April 9, 2013 (``ASB 
767-21A0247, R1''). The service information describes procedures for 
changing (modifying) the 3-way valve control logic and main cargo air 
distribution system (MCADS), and installing an FDARS. These documents 
are distinct since they apply to different airplane models.
    <bullet> Boeing Alert Service Bulletin 767-21A0253, dated October 
12, 2012. The service information describes procedures for replacing 
the existing duct, installing an FDARS, changing (modifying) the 3-way 
valve control logic, and installing a new altitude switch and pitot 
tube.
    <bullet> Boeing Alert Service Bulletin 767-21A0254, dated June 7, 
2013. The service information describes procedures for replacing the 
duct with a new duct; installing an FDARS (including the installation 
of mounting brackets, ducts, orifice, outlet valve, and screen); and 
activating the 3-way valve logic (including modification of the 
associated wiring and related actions).
    <bullet> Boeing Service Bulletin 767-31-0073, dated October 12, 
1995. The service information describes procedures for installing a 
maintenance data selection system for the engine indication and crew 
alerting system.
    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.

    According to the manufacturer, some of the costs of this 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

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),

[[Page 4780]]

    (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.
