Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by reports of wear damage found between the bonding clamps and the fuel feed tubes inside the left- and right-hand fuel tanks. This AD requires repetitive inspections of the fuel feed tubes for damage, replacement if necessary, and modification of the fuel feed line installation inside the left- and right-hand fuel tanks, which would terminate the repetitive inspections, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
TCCA, which is the aviation authority for Canada, has issued TCCA
AD CF-2019-19R1, issued November 1, 2019 (TCCA AD CF-2019-19R1) (also
referred to as the Mandatory Continuing Airworthiness Information, or
the MCAI), to correct an unsafe condition for certain Airbus Canada
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes.
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 May 28, 2021 (86 FR 28719).
The NPRM was prompted by reports of wear damage found between the
bonding clamps and the fuel feed tubes inside the left- and right-hand
fuel tanks. The NPRM proposed to require repetitive inspections of the
fuel feed tubes for damage, replacement if necessary, and modification
of the fuel feed line installation inside the left- and right-hand fuel
tanks, which would terminate the repetitive inspections, as specified
in TCCA AD CF-2019-19R1.
The FAA is issuing this AD to address failure of certain fuel feed
tubes, which could lead to a severe fuel imbalance or fuel starvation
of one engine, or in the event of the failure of multiple fuel tubes
feeding both engines, could result in an in-flight shutdown of both
engines. See the MCAI for additional background information.
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 an additional comment from Delta Air Lines (DAL).
The following presents the comment received on the NPRM and the FAA's
response.
Request for an Optional Method of Compliance
DAL asked that the FAA add an optional method of compliance to the
proposed AD. DAL recommended an additional exception be added in
paragraph (h)(5) of the proposed AD to specify that: ``It is acceptable
to accomplish Airbus Canada Limited Partnership Service Bulletin BD500-
282004, Issue No. 001, dated August 30, 2019, concurrently with Airbus
Canada Limited Partnership Service Bulletin BD500-282005, Issue No.
001, dated August 30, 2019, as terminating action for Part I and Part
II of TCCA AD CF-2019-19R1.'' DAL stated that Airbus Canada Limited
Partnership Service Bulletin BD500-282005 (which is not required by the
proposed AD) also modifies the fuel feed system. DAL noted that doing
the service bulletins
[[Page 7028]]
concurrently would require reordering and eliminating steps from the
service information. DAL stated that these changes would not alter the
final configuration of Airbus Canada Limited Partnership Service
Bulletin BD500-282004, Issue No. 001, dated August 30, 2019. DAL noted
the changes simply allow these modifications to be done concurrently.
DAL concluded that both service bulletins are FAA approved.
The FAA disagrees with the commenter's request. An operator may
always do additional work while performing tasks required by an AD
without the need for an exemption or an alternate method of compliance
(AMOC), as long as those tasks do not impact compliance with the AD.
However, in this case, DAL is proposing to reorder or eliminate certain
steps in the required service information. Although DAL provided some
information, it did not provide sufficient data to allow the FAA to
conclusively determine that the proposed changes would provide an
acceptable level of safety. In addition, the FAA does not consider it
appropriate to include provisions in an AD applicable only to a single
operator's unique use of required service information. However, under
the provisions of paragraph (j)(1) of this AD, the FAA will consider
requests for an AMOC. Therefore, the FAA has not changed this AD in
this regard.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety requires adopting this AD as
proposed. 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. Accordingly, the FAA is issuing this AD to
address the unsafe condition on these products.
Related Service Information Under 1 CFR Part 51
TCCA AD CF-2019-19R1 describes procedures for repetitive
inspections of the fuel feed tubes for damage, replacement if any
damage is found, and modification of the fuel feed line installation
inside the left- and right-hand fuel tanks, which would terminate the
repetitive inspections.
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.
Interim Action
The FAA considers this AD interim action. If final action is later
identified, the FAA might consider further rulemaking then.
Costs of Compliance
The FAA estimates that this AD affects 46 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 91 work-hours x $85 per hour = Up to $15,265.......... Up to $23,000.......... Up to $1,058,000.
Up to $7,735.
----------------------------------------------------------------------------------------------------------------
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
------------------------------------------------------------------------
3 work-hours x $85 per hour = Up to $77,000..... Up to $77,255.
$255.
------------------------------------------------------------------------
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.
