Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain The Boeing Company Model 747-8F and 747-8 series airplanes. 
This AD was prompted by a report of unusual flight instrument and 
engine indication and crew alerting system (EICAS) behavior. This AD 
requires inspecting the left, center, and right electronic flight 
instrument system (EFIS)/EICAS interface unit (EIU) for certain serial 
numbers and replacement if necessary. The FAA is issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective May 13, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 13, 2022

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain The Boeing 
Company Model 747-8F and 747-8 series airplanes. The NPRM published in 
the Federal Register on November 15, 2021 (86 FR 62960). The NPRM was 
prompted by a report of unusual flight instrument and EICAS behavior. 
In the NPRM, the FAA proposed to require inspecting the left, center, 
and right EFIS/EIU for certain serial numbers and replacement if 
necessary. The FAA is issuing this AD to address the possible display 
of incorrect information in the integrated display system (IDS). This 
condition, if not addressed, could result in reduced ability of the 
flightcrew to maintain continued safe flight and landing of the 
aircraft.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from three commenters, including Boeing, 
an individual, and Qatar Airways. The following presents the comments 
received on the NPRM and the FAA's response.

Request To Add Missing Serial Number to List of Affected EIUs

    Boeing and Qatar Airways requested a change to the proposed AD to 
add serial number 181MR2 to the list of affected EIUs. The commenters 
noted that the unit was inadvertently excluded from the affected serial 
number list in Figure 1 of Boeing Alert Requirements Bulletin 747-
31A2565 RB, Revision 1, dated September 14, 2021. Qatar Airways noted 
that Boeing stated that the service information will be revised to 
include this EIU serial number. Qatar Airways added that including the 
affected EIU will ensure that affected part does not remain in service 
while eliminating the need to obtain an alternative method of 
compliance (AMOC) for accomplishing the actions required by this AD on 
that EIU.
    The FAA agrees with the request. The FAA has confirmed that this is 
an affected EIU and that the operator with the EIU having serial number 
181MR2 is aware that it is affected and plans to replace the unit as 
required by this AD. The FAA has added paragraph (h)(2) of this AD to 
clarify that serial number 181MR2 is also an affected EIU. The FAA has 
also redesignated paragraph (h) of the proposed AD as paragraph (h)(1) 
of this AD.

Request for Information About Registered Airplanes

    An individual commenter asked how the information about the number 
of affected airplanes was gathered and how many non-U.S. registered 
planes are affected by the proposed AD.
    The FAA gathers this information from public records and from the 
airplane manufacturer. According to those sources, 68 of the airplanes 
affected by this AD are registered outside of the United States.

Conclusion

    The FAA reviewed the relevant data, considered any comments 
received, and determined that air safety requires adopting this AD as 
proposed. Except for minor editorial changes, and any other changes 
described previously, this AD is adopted as proposed in the NPRM. None 
of the changes will increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 747-31A2565 RB, 
Revision 1, dated September 14, 2021. This service information 
specifies procedures for doing an inspection or a review of the 
maintenance and delivery records of the left, center, and right EIUs 
for any affected serial number, and replacing each affected EIU.
    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 ADDRESSES.

Costs of Compliance

    The FAA estimates that this AD affects 8 airplanes of U.S. 
registry. The

[[Page 20700]]

FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
               Action                         Labor cost            Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Inspection.........................  1 work-hour x $85 per hour               $0             $85            $680
                                      = $85.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
inspection. The agency has no way of determining the number of aircraft 
that might need these replacements:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
               Action                         Labor cost                Parts cost           Cost per product
----------------------------------------------------------------------------------------------------------------
Replacement........................  Up to 3 work-hours x $85     Up to $9,600..........  Up to $9,855.
                                      per hour = Up to $255.

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.
    The FAA is 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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
