<![CDATA[
Federal Register / Vol. 82, No. 240 / Friday, December 15, 2017 / Proposed Rules
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to small airplanes and
domestic business jet transport
airplanes to the Director of the Policy
and Innovation Division.
Regulatory Findings
We 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) Is not a ‘‘significant rule’’ under
the DOT Regulatory Policies and
Procedures (44 FR 11034, February 26,
1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Incorporation by reference,
Safety.
The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
■
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:

relevant data, views, or arguments about
this proposed AD. Send your comments
to an address listed under the
ADDRESSES section. Include ‘‘Docket No.
FAA–2017–1107; Product Identifier
2016–NE–22–AD’’ at the beginning of
your comments. We specifically invite

substantive verbal contact we receive
about this proposed AD.
Discussion
We issued AD 2017–12–03,
Amendment 39–18918 (82 FR 27411,
June 15, 2017), (‘‘AD 2017–12–03’’), for
PW PW2037, PW2037M, and PW2040
turbofan engines. AD 2017–12–03
requires installing a software standard
eligible for installation and precludes
the use of EEC software standards
earlier than SCN 5B/I. AD 2017–12–03
resulted from an unrecoverable engine
in-flight shutdown (IFSD) after an ice
crystal icing event. We issued AD 2017–
12–03 to prevent failure of the highpressure turbine (HPT), rotor seizure,
failure of one or more engines, loss of
thrust control, and loss of the airplane.
Actions Since AD 2017–12–03 Was
Issued
Since we issued AD 2017–12–03,
software became available for PW
engines with EEC model number
EEC104–1 with 26K memory. These are
older engine models that did not have
software fixes available when AD 2017–
12–03 was issued.
Related Service Information
We reviewed PW Alert Service
Bulletin (ASB) PW2000 A73–170, dated
July 14, 2016 and PW ASB PW2000
A73–171, dated March 24, 2017. The
ASBs describe procedures for modifying
or replacing the EEC.
FAA’s Determination
We are proposing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
Proposed AD Requirements
This proposed AD would retain all
the requirements of AD 2017–12–03.
This proposed AD would add
additional, older engine models to the
applicability.
Costs of Compliance
We estimate that this proposed AD
affects 587 engines, installed on
airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:

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.
VerDate Sep<11>2014
19:43 Dec 14, 2017
Jkt 244001
We are 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

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.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
E:\FR\FM\15DEP1.SGM
15DEP1
Federal Register / Vol. 82, No. 240 / Friday, December 15, 2017 / Proposed Rules
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to engines, propellers, and
associated appliances to the Manager,
Engine and Propeller Standards Branch,
Policy and Innovation Division.
Regulatory Findings
We have 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 that the proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Is not a ‘‘significant rule’’ under
the DOT Regulatory Policies and
Procedures (44 FR 11034, February 26,
1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.

Discussion
We issued AD 2017-12-03, Amendment 39-18918 (82 FR 27411, June 15,
2017), (``AD 2017-12-03''), for PW PW2037, PW2037M, and PW2040 turbofan
engines. AD 2017-12-03 requires installing a software standard eligible
for installation and precludes the use of EEC software standards
earlier than SCN 5B/I. AD 2017-12-03 resulted from an unrecoverable
engine in-flight shutdown (IFSD) after an ice crystal icing event. We
issued AD 2017-12-03 to prevent failure of the high-pressure turbine
(HPT), rotor seizure, failure of one or more engines, loss of thrust
control, and loss of the airplane.
Actions Since AD 2017-12-03 Was Issued
Since we issued AD 2017-12-03, software became available for PW
engines with EEC model number EEC104-1 with 26K memory. These are older
engine models that did not have software fixes available when AD 2017-
12-03 was issued.
Related Service Information
We reviewed PW Alert Service Bulletin (ASB) PW2000 A73-170, dated
July 14, 2016 and PW ASB PW2000 A73-171, dated March 24, 2017. The ASBs
describe procedures for modifying or replacing the EEC.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would retain all the requirements of AD 2017-12-
03. This proposed AD would add additional, older engine models to the
applicability.
Costs of Compliance
We estimate that this proposed AD affects 587 engines, installed on
airplanes of U.S. registry.
We estimate the following costs to comply with this proposed AD:
Estimated costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
EEC software installation............. 1.8 work-hours x $85 per 0 $153 $89,811
hour = $153.

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.
We are 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C.
[[Page 59559]]
In accordance with that order, issuance of ADs is normally a function
of the Compliance and Airworthiness Division, but during this
transition period, the Executive Director has delegated the authority
to issue ADs applicable to engines, propellers, and associated
appliances to the Manager, Engine and Propeller Standards Branch,
Policy and Innovation Division.
Regulatory Findings
We have 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 that the proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD)
2017-12-03, Amendment 39-18918 (82 FR 27411), and adding the following
new AD:
Pratt & Whitney Division: Docket No. FAA-2017-1107; Product
Identifier 2016-NE-22-AD.
(a) Comments Due Date
The FAA must receive comments on this AD action by January 29,
2018.
(b) Affected ADs
