Background
The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD that
would apply to certain Airbus Canada Limited Partnership Model BD-500-
1A11 airplanes. The NPRM published in the Federal Register on December
20, 2022 (87 FR 77763). The NPRM was prompted by AD CF-2022-04, dated
February 14, 2022, issued by Transport Canada, which is the aviation
authority for Canada (Transport Canada AD CF-2022-04). Transport Canada
AD CF-2022-04 states that the nose radome lightning diverter strips on
certain aircraft were painted in production; paint on the diverter
strips can compromise the nose radome lightning protection. Reduced
effectiveness of the diverter strips can lead to the puncture of the
nose radome by lightning and potential arc attachment to antennas,
structures, and other equipment in the area of the nose radome. The
unsafe condition, if not addressed, could result in damage to the
localizer or glideslope antennas, and consequent loss of instrument
landing system localizer inputs or deviation information.
In the NPRM, the FAA proposed to require inspecting for paint on
the diverter strips on the nose radome, and replacing the nose radome,
if necessary, as specified in Transport Canada AD CF-2022-04.
The FAA issued an SNPRM to amend 14 CFR part 39 by adding an AD
that would apply to certain Airbus Canada Limited Partnership Model BD-
500-1A11 airplanes. The SNPRM published in the Federal Register on July
14, 2023 (88 FR 45102). The SNPRM was prompted by a determination that
the applicability should be revised because the affected nose radomes
may be installed as rotable spares on airplanes outside of the
applicability of the NPRM, thereby subjecting those airplanes to the
identified unsafe condition. In the SNPRM, the FAA proposed to expand
the applicability to apply to airplanes equipped with specific part
numbers and serial numbers of nose radomes.
Actions Since the SNPRM Was Issued
Since the FAA issued the SNPRM, the FAA determined that the
applicability of the proposed AD should be revised. The FAA has
determined that the affected nose radomes may be installed as rotable
spares on the Airbus Canada Limited Partnership Model BD-500-1A10
airplane model, which is currently outside of the applicability of the
NPRM and SNPRM, thereby subjecting those airplanes to the identified
unsafe condition. Therefore, this proposed AD has been expanded to
apply to Model BD-500-1A10 airplanes, as well as Model BD-500-1A11
airplanes, equipped with the specific part numbers and serial numbers
previously
[[Page 12790]]
addressed. The FAA is proposing this AD to address reduced
effectiveness of the diverter strips, which could result in damage to
the localizer or glideslope antennas, and consequent loss of instrument
landing system localizer or deviation information.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-1650.
Comments
The FAA received comments from the Air Line Pilots Association,
International (ALPA), who supported the SNPRM without change.
The FAA received additional comments from Delta Airlines. The
following presents the comments received on the SNPRM and the FAA's
response to each comment.
Request for Change to Applicability
Delta requested the proposed applicability be changed to include
Model BD-500-1A10 airplanes. Delta stated that the nose radome is a
rotable component that is also compatible with Model BD-500-1A10
airplanes, as specified in the A220 Illustrated Parts Data Publication
(IPDP), and may be moved from the original Model BD-500-1A11 airplane
to a Model BD-500-1A10 airplane over time.
The FAA agrees with the request to include Model BD-500-1A10
airplanes to the applicability in this proposed AD after verifying with
Transport Canada that this model aircraft is affected by the unsafe
condition. The FAA has revised paragraph (c) of this proposed AD
accordingly.
Request for Revision of Affected Part Numbers and Serial Numbers
Delta requested the removal of the following part numbers from
paragraph (i) of the proposed AD (in the SNPRM): C01204101-003,
C01204101-005, C01204101-011. Delta also requested that paragraph (i)
of the proposed AD (in the SNPRM) be revised to include the following
serial numbers: S456997, S570556, S626945, S866894, T099675, T471773,
T595935. Delta stated that Airbus Canada confirmed only the radomes
having part and serial numbers specified in paragraph (c) of the
proposed AD (in the SNPRM) are affected by the unsafe condition.
The FAA agrees with the request for the reasons provided, and has
revised paragraph (i) of this proposed AD accordingly.
Request for Correction to Issue Date on Reference Material
Delta requested the review and, if applicable, correction to the
reference issuance date of SB BD500-538009, Issue 001 in paragraph (j)
of the proposed AD (in the SNPRM). Delta stated that it believes the
issuance date should be May 9, 2022.
The FAA agrees with Delta's request to correct the issuance date of
SB BD500-538009, Issue 001 from April 8, 2022 to May 9, 2022, and has
revised paragraph (j) of this proposed AD accordingly.
Related Service Information Under 1 CFR Part 51
Transport Canada AD CF-2022-04 specifies procedures for inspecting
for paint on the lightning diverter strips on the nose radome, and
replacing the nose radome if the lightning diverter strips are painted.
The FAA also reviewed Airbus Canada Limited Partnership A220
Service Bulletin BD500-538009, Issue 002, dated June 2, 2022. This
service information specifies procedures for inspecting for paint on
the lightning diverter strips on the nose radome, and replacing and
painting the nose radome if the lightning diverter strips are painted.
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 ADDRESSES.
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 and
service information referenced above. The FAA is issuing this SNPRM
after determining that the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Certain changes described above expand the scope of the SNPRM. As a
result, it is necessary to reopen the comment period to provide
additional opportunity for the public to comment on this SNPRM.
Proposed AD Requirements in This SNPRM
This proposed AD would require accomplishing the actions specified
in Transport Canada AD CF-2022-04 described previously, except for any
differences identified as exceptions in the regulatory text of this
proposed AD.
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, the
FAA proposes to incorporate Transport Canada AD CF-2022-04 by reference
in the FAA final rule. This proposed AD would, therefore, require
compliance with Transport Canada AD CF-2022-04 in its entirety through
that incorporation, except for any differences identified as exceptions
in the regulatory text of this proposed AD. Service information
required by Transport Canada AD CF-2022-04 for compliance will be
available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2022-1650 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 7 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
6 work-hours x $85 per hour = $510........................... $0 * $510 $3,570
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the parts cost estimate for the nose radome
replacement.
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this proposed AD may be covered under warranty, thereby reducing the
cost impact on affected operators.
[[Page 12791]]
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
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
