Abstract
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 series airplanes. This AD was prompted by a report that after a certain circuit breaker tripped, power to the two pitot-static (P/S) probe heaters on the right-hand side was lost, and the flightcrew discovered conflicting procedures in the flightcrew operations manual/quick reference handbook (FCOM/QRH). This AD requires revising the existing airplane flight manual (AFM) to incorporate procedures to be applied during P/S probe heater failure conditions. The FAA is issuing this AD to address the unsafe condition on these products.

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 747-400 series airplanes. This AD was
prompted by a report that after a certain circuit breaker tripped,
power to the two pitot-static (P/S) probe heaters on the right-hand
side was lost, and the flightcrew discovered conflicting procedures in
the flightcrew operations manual/quick reference handbook (FCOM/QRH).
This AD requires revising the existing airplane flight manual (AFM) to
incorporate procedures to be applied during P/S probe heater failure
conditions. The FAA is issuing this AD to address the unsafe condition
on these products.
DATES: This AD is effective September 15, 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 747-400 series airplanes. The NPRM published in the
Federal Register on December 28, 2021 (86 FR 73694). The NPRM was
prompted by a report that after a certain circuit breaker tripped,
power to the two P/S probe heaters on the right-hand side was lost, and
the flightcrew discovered conflicting procedures in the FCOM/QRH. In
the NPRM, the FAA proposed to require revising the existing AFM to
incorporate procedures to be applied during P/S probe heater failure
conditions. The FAA is issuing this AD to address the conflicting
procedures, which could result in the transmission of potentially
inaccurate pitot static pressure data to the air data computer (ADC),
resulting in erroneous or misleading air data being displayed, which,
in combination with a stall, overspeed, overrun, or short/hard landing
condition, could result in reduced ability of the flightcrew to
maintain continued safe flight and landing of the airplane.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from the Air Line Pilots Association,
International (ALPA) who supported the NPRM without change.
The FAA received additional comments from a commenter, Cathay
Pacific Airways Ltd. (Cathay Pacific). The following presents the
comments received on the NPRM and the FAA's response to each comment.
Request To Clarify Requirements of Paragraph (g) of the Proposed AD
Cathay Pacific requested that the FAA clarify the requirements of
paragraph (g) of the proposed AD to allow removing a copy of the AD
from the AFM. Cathay Pacific commented that inserting a copy of the AD
into the AFM is not a routine procedure, and that it also appears that
once the AFM is revised to include the information provided in the AD,
there is no provision within paragraph (g) of the proposed AD to remove
the copy of the AD from the AFM. Cathay Pacific suggested revising the
proposed AD to add a provision to permit the AD copy to be removed from
the AFM.
The FAA agrees to clarify the requirements but disagrees with the
suggestion to revise this AD. Paragraph (g) of this AD requires
revising the AFM to include the changes specified in paragraphs (g)(1)
through (4) of this AD, and allows for inserting a copy of the AD as
one means of complying with the requirement to revise the AFM.
Inserting a copy of the AD is an option that has been allowed in other
ADs. There is no need to specify removing the copy of the AD when an
operator subsequently uses another method to comply with the AD. After
an operator uses another method to revise the AFM to include the
changes to the AFM text specified in paragraphs (g)(1) through (4) of
this AD, an operator may remove the copy of the AD. The FAA has not
changed the AD in this regard.
Request To Clarify Method for Complying With Requirements of Paragraph
(g) of the Proposed AD
Cathay Pacific requested that the FAA clarify if a temporary
revision to the AFM is acceptable to comply with paragraph (g) of the
proposed AD. Cathay Pacific remarked that the manufacturer might issue
a temporary revision to the AFM which includes the information and
asked if using a temporary revision would be considered a means of
compliance with paragraph (g) of the proposed AD. Cathay Pacific
further asked that if a temporary revision is an acceptable means of
compliance, could the FAA revise paragraph (g) of the proposed AD to
also specify temporary revisions as a means of compliance.
The FAA agrees to clarify but does not agree to revise the AD. A
temporary revision to the AFM, provided it has the specified changes
required by paragraph (g) of this AD, is a means of revising the AFM.
The language in paragraph (g) of this AD is designed to allow revising
the AFM to incorporate the required
[[Page 49510]]
changes through various methods, so long as the language in the revised
AFM is identical to the changes specified in paragraphs (g)(1) through
(4) of this AD. The FAA has not changed the AD in this regard.
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.
Costs of Compliance
The FAA estimates that this AD affects 114 airplanes of U.S.
registry. The 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
----------------------------------------------------------------------------------------------------------------
AFM Revision...................... 1 work-hour x $85 per None................. $85 $9,690
hour = $85.
----------------------------------------------------------------------------------------------------------------
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.

The Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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:
2022-15-07 The Boeing Company: Amendment 39-22127; Docket No. FAA-
2021-1005; Project Identifier AD-2021-00842-T.
(a) Effective Date
This airworthiness directive (AD) is effective September 15,
2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to The Boeing Company Model 747-400 series
airplanes, certificated in any category, having a three air data
computer (ADC) configuration, except for airplanes on which the

on the right-hand side was lost, and the flightcrew discovered
conflicting procedures in the flightcrew operations manual/quick
reference handbook (FCOM/QRH). The FAA is issuing this AD to address
the conflicting procedures, which could result in the transmission
of potentially inaccurate pitot static pressure data to the ADC,
resulting in erroneous or misleading air data being displayed,
which, in combination with a stall, overspeed, overrun, or short/
hard landing condition, could result in reduced ability of the
flightcrew to maintain continued safe flight and landing of the
airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Airplane Flight Manual (AFM) Revisions
Within 90 days after the effective date of this AD, revise the
Non-Normal Procedures Section of the existing AFM to include the
changes specified in paragraphs (g)(1) through (4) of this AD.
