Abstract
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 series airplanes. This AD was prompted by a finding that when the autopilot is engaged, the architecture of the autopilot system does not automatically disconnect the autopilot in response to pilot application of a pitch input or when the electric pitch trim switch on either pilot control wheel is operated. This AD requires modifying the autopilot engagement circuit. The FAA is issuing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
BAE Systems (Operations) Limited Model BAe 146 series airplanes. This
AD was prompted by a finding that when the autopilot is engaged, the
architecture of the autopilot system does not automatically disconnect
the autopilot in response to pilot application of a pitch input or when
the electric pitch trim switch on either pilot control wheel is
operated. This AD requires modifying the autopilot engagement circuit.
The FAA is issuing this AD to address the unsafe condition on these
products.
DATES: This AD is effective January 4, 2023.

The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 4,
2023.

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 all BAE Systems
(Operations) Limited Model BAe 146 series airplanes. The NPRM published
in the Federal Register on August 22, 2022 (87 FR 51271). The NPRM was
prompted by AD G-2022-0002, dated February 11, 2022, issued by United
Kingdom Civil Aviation Authority (U.K. CAA), which is the aviation
authority for the United Kingdom (referred to after this as the MCAI).
The MCAI states that when the autopilot is engaged, the architecture of
the autopilot system does not automatically disconnect the autopilot in
response to pilot application of a pitch input or when the electric
pitch trim switch on either pilot control wheel is operated.
In the NPRM, the FAA proposed to require modifying the autopilot
engagement circuit. The FAA is issuing this AD to address continued
autopilot engagement after flightcrew input to disengage the autopilot,
which could lead to reduced controllability of the airplane.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-1053.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
referenced above. The FAA reviewed the relevant data and determined
that air safety requires adopting this AD as proposed. Accordingly, the
FAA is issuing this AD to address the unsafe condition on this product.
Except for minor editorial changes, 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
BAE Systems (Operations) Limited has issued Modification Service
Bulletin SB.22-072-36262A, dated September 14, 2021. This service
information describes procedures for modifying the autopilot engagement
circuit, including the wiring, relay, and certain module blocks. 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.
Costs of Compliance
The FAA estimates that this AD affects 20 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
130 work-hours x $85 per hour = $11,050...................... $2,124 $13,174 $263,480
----------------------------------------------------------------------------------------------------------------
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
[[Page 73448]]
under the criteria of the Regulatory Flexibility Act.
