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 Airbus Canada
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. The
NPRM published in the Federal Register on July 20, 2023 (88 FR 46702).
The NPRM was prompted by AD CF-2023-28, dated May 4, 2023, issued by
Transport Canada, which is the aviation authority for Canada (Transport
Canada AD CF-2023-28) (also referred to as the MCAI). The MCAI states a
deficiency in the design of the engine fire extinguishing control and
indication system was discovered. After the loss of one hot battery DC
bus, the AVAIL legend on BTL 1 and BTL 2 push button annunciators
(PBAs) will not illuminate green upon pressing the corresponding ENG
FIRE PBA. This condition affects both L ENG FIRE and R ENG FIRE PBAs on
the overhead panel. The misleading indication given by the AVAIL legend
on BTL 1 and BTL 2 PBAs will affect the crew's assessment of the
situation. The crew may hesitate to extinguish an engine fire despite
having access to a functional engine fire extinguishing system, or may
reselect the FIRE PBA, resulting in loss of the ability to isolate and
extinguish the fire.
In the NPRM, the FAA proposed to require installing a software
update to the ICCP RDC, as specified in Transport Canada AD CF-2023-28.
The FAA is issuing this AD to address the unsafe condition on these
products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-1501.
Discussion of Final Airworthiness Directive
Comments
The FAA received one comment from Air Line Pilots Association,
International (ALPA) who supported the NPRM without change.
The FAA received an additional comment from Delta Air Lines
(Delta). The following presents the comment received on the NPRM and
the FAA's response.
Request To Clarify Software Installation Requirements
Delta requested that an additional exception be added to paragraph
(h) of the proposed AD to clarify that it is acceptable to use a
different method of upgrading the software, using Airbus Canada Limited
Partnership Service Bulletin BD500-311001, Issue 001, dated March 14,
2023, only as a reference. Delta explained that it has a different
policy for installing software that requires the use of a Portable
Maintenance Access Terminal (PMAT), model PMAT2000, instead of a USB
device.
The FAA partially agrees with the proposed changes. The FAA agrees
to clarify that the PMAT method is
[[Page 69019]]
permitted, but the FAA will not require the use of a specific model of
PMAT. Also, using the service information as a reference must be
specified in a note rather than in the paragraph itself. Therefore, a
single paragraph (h)(2) has been added to this AD to provide this
clarification, and a note has been added regarding the use of Airbus
Canada Limited Partnership Service Bulletin BD500-311001, Issue 001,
dated March 14, 2023, as a reference.
Conclusion
These products have been approved by the aviation authority of
another country and are 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,
considered the comments received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on these products. 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
Transport Canada AD CF-2023-28 specifies procedures for installing
the software update to the ICCP RDC to restore the intended
functionality of the PBA green indications. 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.
Costs of Compliance
The FAA estimates that this AD affects 76 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 6 work-hours x $85 per hour Up to $7,500........ Up to $8,010....... Up to $608,760.
= Up to $510.
----------------------------------------------------------------------------------------------------------------
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.
