We are superseding Airworthiness Directive (AD) 2012-24-10 for certain The Boeing Company Model 747-400 and -400F series airplanes. AD 2012-24-10 required installing new software, replacing the duct assembly with a new duct assembly, making wiring changes, and routing certain wire bundles. This new AD retains the requirements of AD 2012- 24-10 and requires installing a new or serviceable pressure switch bracket and altitude pressure switch. This new AD also adds an airplane to the applicability. This AD was prompted by reports of intermittent or blank displays of a certain integrated display unit (IDU) that were due to an intermittent false electrical ground that was not addressed by the software installation or wiring changes required by AD 2012-24- 10. We are issuing this AD to prevent IDU malfunctions, which could affect the ability of the flightcrew to read primary displays for airplane attitude, altitude, or airspeed, and consequently reduce the ability of the flightcrew to maintain control of the airplane.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2012-24-10 for 
certain The Boeing Company Model 747-400 and -400F series airplanes. AD 
2012-24-10 required installing new software, replacing the duct 
assembly with a new duct assembly, making wiring changes, and routing 
certain wire bundles. This new AD retains the requirements of AD 2012-
24-10 and requires installing a new or serviceable pressure switch 
bracket and altitude pressure switch. This new AD also adds an airplane 
to the applicability. This AD was prompted by reports of intermittent 
or blank displays of a certain integrated display unit (IDU) that were 
due to an intermittent false electrical ground that was not addressed 
by the software installation or wiring changes required by AD 2012-24-
10. We are issuing this AD to prevent IDU malfunctions, which could 
affect the ability of the flightcrew to read primary displays for 
airplane attitude, altitude, or airspeed, and consequently reduce the 
ability of the flightcrew to maintain control of the airplane.

DATES: This AD is effective October 27, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 27, 
2015.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2012-24-10, Amendment 39-17280 (77 FR 73908, 
December 12, 2012). AD 2012-24-10 applied to certain The Boeing Company 
Model 747-400 and -400F series airplanes. The NPRM published in the 
Federal Register on February 18, 2015 (80 FR 8568). The NPRM was 
prompted by reports of intermittent or blank displays of a certain IDU 
that were due to an intermittent false electrical ground that was not 
addressed by the software installation or wiring changes required by AD 
2012-24-10.
    The NPRM (80 FR 8568, February 18, 2015) proposed to retain the 
requirements of AD 2012-24-10. The NPRM also proposed to require 
installing a new or serviceable pressure switch bracket and altitude 
pressure switch, and add an airplane having variable number RT061 as 
Group 21 to the applicability of the existing AD. We are issuing this 
AD to prevent IDU malfunctions, which could affect the ability of the 
flightcrew to read primary displays for airplane attitude, altitude, or 
airspeed, and consequently reduce the ability of the flightcrew to 
maintain control of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (80 FR 
8568, February 18, 2015) and the FAA's response.

Request To Clarify Purpose of Altitude Pressure Switch

    Boeing requested that we revise the wording in the Discussion 
section to clarify that the altitude pressure switch provides an 
independent and redundant signal to the equipment cooling three-way 
valve. Boeing explained that the logic to transition the three-way 
valve through an altitude of 25,000 feet was already present through a 
signal from the environmental control system miscellaneous card 
(ECSMC). The commenter added that the logic

[[Page 57084]]

redundancy is described correctly elsewhere in the NPRM (80 FR 8568, 
February 18, 2015).
    We agree with the commenter's request because changing the wording 
clarifies the intent of Boeing Special Attention Service Bulletin 747-
21-2533, dated February 13, 2014, which describes procedures for 
installing an altitude pressure switch on the forward side of the 
station 400 bulkhead for the three-way valve of the equipment cooling 
system. We have revised the description of the service information, 
which is provided in the Related Service Information under 1 CFR part 
51 section in this final rule.

Conclusion

    We reviewed the relevant data, considered the comment 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:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 8568, February 18, 2015) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 8568, February 18, 2015).

Related Service Information Under 1 CFR Part 51

    Boeing has issued the following service information.
     Boeing Alert Service Bulletin 747-21A2523, Revision 2, 
dated June 7, 2013. This service information describes procedures for 
changing the wiring and operating logic of the equipment cooling three-
way valve and replacing the existing duct assembly with a new duct 
assembly on the main distribution manifold of the air conditioning 
system.
     Boeing Special Attention Service Bulletin 747-21-2532, 
dated February 13, 2014. This service information describes procedures 
for installing an altitude pressure switch on the forward side of the 
station 400 bulkhead for the three-way valve of the equipment cooling 
system.
     Boeing Special Attention Service Bulletin 747-21-2533, 
dated February 13, 2014. This service information describes procedures 
for adding a second altitude signal to the switching logic for the 
three-way valve to provide a second, independent altitude signal for 
the equipment cooling 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 of this 
AD.

Costs of Compliance

    We estimate that this AD affects 33 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

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

    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

    We have determined that 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),
    (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.
