RIN 2120-AA64
Airworthiness Directives; Daher Aerospace (Type Certificate
Previously Held by SOCATA) Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive
(AD)
for certain Daher Aerospace (type certificate previously held by
SOCATA) Model TBM 700 airplanes. This proposed AD results from
mandatory continuing airworthiness information (MCAI) originated by an
aviation authority of another country to identify and correct an unsafe
condition on an aviation product. The unsafe condition that is the
subject of the MCAI is ice accumulation on the oil cooler air inlet
duct fin. This proposed AD would require modifying the oil cooler air
induction duct. The FAA is proposing this AD to address the unsafe
condition on these products.
DATES: The FAA must receive comments on this proposed AD by October
4,
2021.
ADDRESSES: You may send comments, using the procedures found in
14 CFR
11.43 and 11.45, by any of the following methods:
Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow

SUPPLEMENTARY INFORMATION:
Comments Invited
The FAA invites you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under the ADDRESSES section. Include "Docket No. FAA-2020-1069;
Project Identifier 2018-CE-039-AD" at the beginning of your comments.
The most helpful comments reference a specific portion of the proposal,
explain the reason for any recommended change, and include supporting
data. The FAA will consider all comments received by the closing date
and may amend this proposal because of those comments.
Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
https://www.regulations.gov, including any personal information you
provide. The agency will also post a report summarizing each
substantive verbal contact received about this NPRM.
Confidential Business Information
CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this NPRM contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as "PROPIN." The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to Greg
Johnson, Aviation Safety Engineer, FAA, General Aviation & Rotorcraft
Section, International Validation Branch, 901 Locust, Room 301, Kansas
City, MO 64106. Any commentary that the FAA receives which is not
specifically designated as CBI will be placed in the public docket for
this rulemaking.
Background
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2018-0133, dated June 22, 2018, and corrected June 25, 2018 (referred
to after this as "the MCAI"), to address the unsafe condition on
certain Daher Aerospace (type certificate previously held by SOCATA)
Model TBM 700 airplanes. The MCAI states:
During flight testing in icing conditions, oil temperature
increase was observed. Subsequent investigation determined that the
loss of efficiency of the oil cooler system was due to ice
accumulation on the engine air induction duct fins.
This condition, if not corrected, could lead to uncommanded
engine in-flight shut-down and reduced control of the aeroplane.
To address this potential unsafe condition, DAHER AEROSPACE
developed MOD 70-0616-79 for aeroplanes in production, removing the
4 upper fins of the oil cooler air induction duct to avoid ice
accumulation, available for in-service aeroplanes through the SB
[Daher Aerospace Service Bulletin 70-254 79, dated April 18, 2018].
For the reasons described above, this [EASA] AD requires
modification of the oil cooler air induction duct.
You may examine the MCAI in the AD docket at https://www.regulations.gov
by searching for and locating Docket No. FAA-2020-1069.
Although the unsafe condition statement in the MCAI identifies the
cause as ice accumulation on the engine air induction fin, the FAA has
determined that this does not accurately identify the affected air
path. The affected area is the oil cooler air inlet duct fin.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Daher Aerospace Service Bulletin SB 70-254, dated
April 2018. The service information specifies procedures for removing
the four upper fins of the oil cooler air induction duct and for re-
identifying the oil cooler air induction duct with a new part number.
This service information 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.
Other Related Service Information
The FAA also reviewed Daher Aerospace Service Bulletin SB 70-231,
Revision 1, dated July 2018; and Daher Aerospace Service Bulletin SB
70-219, Revision 2, dated July 2018. The service information identifies
the kit number and installation procedures for replacing the oil cooler
air induction duct.
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 NPRM
after determining the unsafe condition described previously is likely
to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This AD requires accomplishing the actions specified in the service
information already described.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect up to 807 products of U.S. registry. The FAA also estimates that
it would take about 3 work-hours per product to comply with the
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Required parts would cost about $50 per product.
Based on these figures, the FAA estimates the total cost of the
proposed AD on U.S. operators to be up to $246,135 at $305 per product.
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.
