SUPPLEMENTARY INFORMATION:
Background
TCCA, which is the aviation authority for Canada, has issued TCCA
AD CF-2020-41, issued October 15, 2020 (TCCA AD CF-2020-41) (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 April 16, 2021 (86 FR 20097).
The NPRM was prompted by reports of IFESs; investigations are ongoing
to determine the root cause. Investigation results indicated that an
IFES could be caused by high altitude climbs at higher thrust settings
on engines with certain thrust ratings. The NPRM proposed to require
amending the existing AFM to incorporate a new limitation and revise
certain normal procedures, as specified in TCCA AD CF-2020-41.
The FAA is issuing this AD to provide the flightcrew with
information and procedures for operation above 29,000 feet to prevent
uncontained failure of an engine during an IFES, which could result in
structural damage and reduced structural integrity of the airplane. See
the MCAI for additional background information.
Comments
The FAA received comments from Air Line Pilots Association,
International (ALPA), who supported the NPRM without change.
The FAA received additional comments from one commenter. The
following presents the comment received on the NPRM and the FAA's
response.
Request To Amend the Existing Airplane Flight Manual
Delta Air Lines Inc. (Delta) asked that the proposed AD also
require amending the AFM with Supplement 21 at Issue 016 for Model
A220-300 (BD-500-1A11) airplanes. Delta stated that the proposed AD
requires amending the AFM with Supplement 21 for only Model A220-100
(BD-500-1A10) airplanes, and should include amending the AFM for both
models.
The FAA agrees with the commenter's request. Paragraph (h)(2) of
the proposed AD incorrectly identified only the A220-100 AFM. The FAA
intended to require the AFM revision based on the applicable AFM for
both Model BD-500-1A10 and BD-500-1A11 airplanes, including both the
A220-100 and A220-300 AFMs. The FAA has added the AFM amendment for
Model A220-300 (Model BD-500-1A11) airplanes to paragraph (h)(2) of
this AD.
[[Page 71556]]
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule with the change described previously
and minor editorial changes. The FAA has determined that these minor
changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
The FAA also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.
Related Service Information Under 1 CFR Part 51
TCCA AD CF-2020-41 specifies procedures for amending the applicable
AFM to incorporate a new limitation and revise the normal procedures to
limit the engine N1 setting for flights above 29,000 feet.
Airbus Canada Limited Partnership has issued Supplement 21--
Operation Above 29000 Feet, of Airbus A220-100 Airplane Flight Manual,
Publication BD500-3AB48-22200-00, and Airbus A220-300 Airplane Flight
Manual Publication BD500-3AB48-32200-00, both Issue 016, dated October
16, 2020. These supplements specify limitations, information, and
procedures for operation above 29,000 feet. These documents are
distinct since they apply to different airplane models.
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 42 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............................. $0 $85 $3,570
----------------------------------------------------------------------------------------------------------------
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.

unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in
accordance with, paragraph A., of TCCA AD CF-2020-41.
[[Page 71557]]
(h) Exceptions to TCCA AD CF-2020-41
(1) Where TCCA AD CF-2020-41 refers to its effective date, this
AD requires using the effective date of this AD.
(2) Where paragraph A. of TCCA AD CF-2020-41 requires amending
the existing airplane flight manual (AFM) by ``incorporating the
SUPPLEMENT 21 Operation above 29000 feet from AFM Revision 15-A
dated 10 September 2020,'' this AD requires amending the existing
AFM by incorporating Supplement 21--Operation Above 29000 Feet, of
Airbus A220-100 Airplane Flight Manual, Publication BD500-3AB48-
22200-00, and Airbus A220-300 Airplane Flight Manual Publication
BD500-3AB48-32200-00, both Issue 016, dated October 16, 2020.
(3) Where paragraph A. of TCCA AD CF-2020-41 specifies to
``[i]nform all flight crews of the new supplement and thereafter
operate the aeroplane accordingly,'' this AD does not require those
actions as those actions are already required by existing FAA
operating regulations.
(4) Where paragraphs B. and C. of TCCA AD CF-2020-41 specify
procedures for a borescope inspection for signs of damage of the 1st
stage axial low-pressure compressor (LPC) rotor of each engine, to
be performed after the AFM N1 limitation has been exceeded, this AD
does not require that action.
(5) Where paragraph C. of TCCA AD CF-2020-41 describes an
optional installation of health management unit reports to monitor
N1 exceedances, this AD does not include that option.
(i) Other FAA AD Provisions
