AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2024-04-
11, which applied to certain Airbus Canada Limited Partnership Model
BD-500-1A10 and BD-500-1A11 airplanes. AD 2024-04-11 required modifying
the variable frequency generator (VFG) power-feeder harness routing.
Since the FAA issued AD 2024-04-11, the FAA received a report of damage
to a VFG power-feeder harness, resulting in the loss of the associated
VFG and the posting of the L GEN FAIL (Caution) message. This AD
continues to require modifying the VFG power-feeder harness routing,
and also requires inspecting the VFG power-feeder harnesses for damage
and clearance, repairing or replacing the VFG power-feeder harnesses if
necessary, modifying and adjusting the VFG power-feeder harnesses if
necessary, and prohibiting dispatch of certain airplanes under certain
master minimum equipment list (MMEL) items; as specified in a Transport
Canada emergency AD, which is incorporated by reference. The FAA is
issuing this AD to address the unsafe condition on these products.

this rulemaking.
Background
The FAA issued AD 2024-04-11, Amendment 39-22690 (89 FR 21179,
March 27, 2024) (AD 2024-04-11), for certain Airbus Canada Limited
Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2024-04-11
was prompted by an MCAI originated
[[Page 86232]]
by Transport Canada, which is the aviation authority for Canada.
Transport Canada issued AD CF-2023-24, dated April 6, 2023 (Transport
Canada AD CF-2023-24), to correct an unsafe condition.
AD 2024-04-11 required modifying the VFG power-feeder harness
routing. The FAA issued AD 2024-04-11 to prevent damage to VFG power-
feeder harnesses from chafing due to vibration. The unsafe condition,
if not addressed, could lead to a loss of generated power from both
VFGs, or to a fire in the case of flammable fluid contact with arcing
wires.
Actions Since AD 2024-04-11 Was Issued
Since the FAA issued AD 2024-04-11, Transport Canada superseded
Transport Canada AD CF-2023-24 and issued Transport Canada Emergency AD
CF-2024-34, dated September 19, 2024 (Transport Canada Emergency AD CF-
2024-34) to correct an unsafe condition for certain Airbus Canada
Limited Partnership (ACLP) Model BD-500-1A10 and BD-500-1A11 airplanes.
The MCAI states damage to a VFG harness has been reported, which
resulted in the loss of the associated VFG and the posting of the L GEN
FAIL (Caution) message. An investigation determined that the in-service
event occurred after the incorporation of Part C of ACLP Service
Bulletin BD500-534101, Issue 007, dated October 2, 2020, which
introduced a new bracket on both sides of the airplane to move the VFG
power-feeder harness away from the wheel bins to prevent chafing.
Transport Canada required the actions in that service bulletin in
Transport Canada AD CF-2023-24 (which corresponds with FAA AD 2024-04-
11) to mitigate the risks associated with VFG power-feeder harness/
wheel bin chafing. It has been discovered that implementation of Part C
of ACLP SB BD500-534101 (Issues 005 through 008) could potentially
cause an unsupported VFG power-feeder harness length in a different
location on both sides of the airplane. In addition, dispatching the
airplane with certain items inoperative under the MMEL might exacerbate
this risk. Transport Canada Emergency AD CF-2024-34 prohibits dispatch
of airplanes under certain MMEL items to mitigate the exacerbated risk
due to dispatching airplanes with certain items inoperative. Transport
Canada subsequently superseded Transport Canada Emergency AD CF-2023-34
and issued Transport Canada Emergency AD CF-2024-34R1, dated October
15, 2024 (Transport Canada Emergency AD CF-2024-34R1) to clarify the
requirements of Part II of Transport Canada Emergency AD CF-2024-34.
Transport Canada Emergency AD CF-2024-34R1 does not change the
requirements or applicability of Transport Canada Emergency AD CF-2024-
34.
The FAA is issuing this AD to address damage to VFG power-feeder
harnesses caused by unsupported VFG power-feeder harness length. The
unsafe condition, if not addressed, could lead to a loss of generated
power from both VFGs and loss of critical aircraft systems if alternate
generators are also lost. You may examine the MCAI in the AD docket at
regulations.gov under Docket No. FAA-2024-2415.
Explanation of Retained Requirements
Although this AD does not explicitly restate the requirements of AD
2024-04-11, this AD retains all of the requirements of AD 2024-04-11.
Those requirements are referenced in Transport Canada Emergency AD CF-
2024-34 and AD CF-2024-34R1, which, in turn, are referenced in
paragraph (g) of this AD.
Material Incorporated by Reference Under 1 CFR Part 51
Transport Canada Emergency AD CF-2024-34 and AD CF-2024-34R1
specify procedures for modifying the VFG power-feeder harness routing,
including a general visual inspection (GVI) for damage at the
intersection of the VFG power-feeder harnesses and the surface of the
wheel bins, and corrective actions including obtaining and following
repair instructions; performing a GVI of the VFG power-feeder harnesses
for damage (including chafing and kinks) and clearance between the VFG
power-feeder harnesses and main landing gear in the retracted position;
repairing or replacing the VFG power-feeder harnesses (includes
repairing wiring or the sleeve); modifying and adjusting the VFG power-
feeder harnesses; and prohibiting dispatch of certain airplanes under
certain MMEL items. These documents are distinct because Transport
Canada Emergency AD CF-2024-34R1 clarifies the requirements of
Transport Canada Emergency AD CF-2024-34. This material 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.
FAA's Determination
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 is issuing this AD after determining that the
unsafe condition described previously is likely to exist or develop on
other products of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in Transport
Canada Emergency AD CF-2024-34 and AD CF-2024-34R1 described
previously, except for any differences identified as exceptions in the
regulatory text of this AD.
Clarification of Airplane Group Definition
Transport Canada defines Group B airplanes as Model BD-500-1A10
airplanes, having serial numbers 50001 through 50047, and Model BD-500-
1A11 airplanes, having serial numbers 55001 through 55070. This AD
clarifies Group B airplanes as only those airplanes on which Part C of
the Accomplishment Instructions of ACLP SB BD500-534101, Issue 005,
dated June 12, 2020, Issue 006, dated August 14, 2020, Issue 007, dated
October 2, 2020, or Issue 008, dated March 13, 2024, has not been done.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, AD
2024-04-11 is retained and Transport Canada Emergency AD CF-2024-34 and
AD CF-2024-34R1 are incorporated by reference in this AD. This AD
requires compliance with Transport Canada Emergency AD CF-2024-34 or AD
CF-2024-34R1 in its entirety through that incorporation, except for any
differences identified as exceptions in the regulatory text of this AD.
Material required by Transport Canada Emergency AD CF-2024-34 and AD
CF-2024-34R1 for compliance will be available at regulations.gov under
Docket No. FAA-2024-2415 after this AD is published.
FAA's Justification and Determination of the Effective Date
Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C.
551 et seq.) authorizes agencies to dispense with notice and comment
procedures
[[Page 86233]]
for rules when the agency, for ``good cause,'' finds that those
procedures are ``impracticable, unnecessary, or contrary to the public
interest.'' Under this section, an agency, upon finding good cause, may
issue a final rule without providing notice and seeking comment prior
to issuance. Further, section 553(d) of the APA authorizes agencies to
make rules effective in less than thirty days, upon a finding of good
cause.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies forgoing notice and comment prior to adoption of this rule
because Transport Canada issued an emergency AD indicating that damage
to a VFG harness resulted in the loss of the associated VFG and the
posting of the L GEN FAIL (Caution) message. Implementation of Part C
of ACLP SB BD500-534101 (Issues 005 through 008) could potentially
cause an unsupported VFG power-feeder harness length in a different
location on both sides of the airplane, which could lead to VFG power-
feeder harness damage in these locations, which could lead to a loss of
generated power from both VFGs and loss of critical aircraft systems if
alternate generators are also lost. Additionally, the compliance time
in this AD is shorter than the time necessary for the public to comment
and for publication of the final rule. Accordingly, notice and
opportunity for prior public comment are impracticable and contrary to
the public interest pursuant to 5 U.S.C. 553(b).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forgo notice and
comment.
Regulatory Flexibility Act (RFA)
The requirements of the RFA do not apply when an agency finds good
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and
comment. Because the FAA has determined that it has good cause to adopt
this rule without notice and comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 17 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
--------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Retained actions from AD 2024-04-11. Up to 51 work-hours x Up to $3,538................ Up to $7,873................ Up to $133,841.
$85 per hour = $4,335.
New GVI............................. 1 work-hour x $85 per $0.......................... $85......................... $1,445.
hour = $85.
--------------------------------------------------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need these on-condition actions:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
Up to 60 work-hours x $85 per $9,940 per harness Up to $15,040 per
hour = Up to $5,100 per side. side.
------------------------------------------------------------------------
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, and
(2) Will not affect intrastate aviation in Alaska.
