Abstract
The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to certain Airbus Canada Limited Partnership Model BD-500- 1A10 airplanes. The NPRM would have required an inspection of the low- pressure distribution supply duct to determine the part number, and replacement if necessary, as specified in a Transport Canada Civil Aviation (TCCA) AD. Since issuance of the NPRM, the FAA has determined that the affected operator has already addressed the unsafe condition by incorporating the proposed required actions on the affected airplanes. Accordingly, the NPRM is withdrawn.

SUMMARY: The FAA is withdrawing a notice of proposed rulemaking (NPRM)
that proposed to adopt a new airworthiness directive (AD) that would
have applied to certain Airbus Canada Limited Partnership Model BD-500-
1A10 airplanes. The NPRM would have required an inspection of the low-
pressure distribution supply duct to determine the part number, and
replacement if necessary, as specified in a Transport Canada Civil
Aviation (TCCA) AD. Since issuance of the NPRM, the FAA has determined
that the affected operator has already addressed the unsafe condition
by incorporating the proposed required actions on the affected
airplanes. Accordingly, the NPRM is withdrawn.
DATES: As of August 25, 2021, the proposed rule, which was published in
[[Page 47420]]
the Federal Register on April 16, 2021 (86 FR 20091), is withdrawn.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued an NPRM that proposed to amend 14 CFR part 39 by
adding an AD that would apply to certain Airbus Canada Limited
Partnership Model BD-500-1A10 airplanes. The NPRM was published in the
Federal Register on April 16, 2021 (86 FR 20091). The NPRM was prompted
by a report that an incorrect low-pressure distribution supply duct may
be installed in the forward cargo compartment. The NPRM proposed to
require an inspection of the low-pressure distribution supply duct to
determine the part number, and replacement if necessary, as specified
in a Transport Canada Civil Aviation (TCCA) AD.
Actions Since the NPRM Was Issued
Since issuance of the NPRM, the FAA has verified that the proposed
actions have been done on the affected airplanes. Therefore, the FAA
has determined that AD action is not appropriate.
Withdrawal of the NPRM constitutes only such action and does not
preclude the FAA from further rulemaking on this issue, nor does it
commit the FAA to any course of action in the future.
Comments
Support for the NPRM
The Air Line Pilots Association, International (ALPA) expressed
support for the NPRM.
Request To Not Issue the Proposed AD
Delta Air Lines (Delta) requested that the proposed AD not be
issued. DAL stated that replacement of the affected part as required by
the proposed AD had already been done on both of the affected
airplanes. Alternatively, Delta requested that the FAA allow use of the
high-pressure ground connection as an alternative to the auxiliary
power units because Delta's affected airplanes had been preserved in
storage and could not be started if necessary to perform a required
leak check. The FAA agrees with the commenter's requests, but because
the FAA is withdrawing the NPRM, Delta's alternative request is no
longer necessary.
FAA's Conclusions
Upon further consideration, the FAA has determined that the NPRM is
unnecessary. Accordingly, the NPRM is withdrawn.
Regulatory Findings
Since this action only withdraws an NPRM, it is neither a proposed
nor a final rule. This action therefore is not covered under Executive
Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979).

The Withdrawal
Accordingly, the notice of proposed rulemaking (Docket No. FAA-
2021-0298), which was published in the Federal Register on April 16,
2021 (86 FR 20091), is withdrawn.
Issued on August 19, 2021.
