Download as PDF 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: ethrower on DSK3G9T082PROD with PROPOSALS ■ Pacific Aerospace Limited: Docket No. FAA– 2017–1184; Product Identifier 2017–CE– 029–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: ESTIMATED COSTS Action Labor cost EEC software installation ................................ 1.8 work-hours × $85 per hour = $153 .......... ethrower on DSK3G9T082PROD with PROPOSALS Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

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:

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

    This AD replaces AD 2017-12-03, Amendment 39-18918 (82 FR 27411, 
June 15, 2017).

(c) Applicability

    This AD applies to:
    (1) All Pratt & Whitney Division (PW) PW2037, PW2037M, and 
PW2040 turbofan engines with electronic engine control (EEC), model 
number EEC104-40 or EEC104-60, installed, with an EEC software 
standard earlier than SCN 5B/I; and
    (2) All PW PW2037, PW2037M, and PW2040 turbofan engines with 
EEC, model number EEC104-1 with part numbers (P/Ns) 1B7484, 1B7486, 
1B7984, or 1B7985, installed, with an EEC software standard earlier 
than SCN 27A.

(d) Subject

    Joint Aircraft System Component (JASC) Code 7321, Fuel Control 
Turbine Engines.

(e) Unsafe Condition

    This AD was prompted by an unrecoverable engine in-flight 
shutdown (IFSD) after an ice crystal icing event. We are issuing 
this AD to prevent failure of the high-pressure turbine (HPT) and 
rotor seizure. The unsafe condition, if not corrected, could result 
in failure of one or more engines, loss of thrust control, and loss 
of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    (1) For an engine with an EEC model number EEC104-40 or EEC104-
60 and a serial number (S/N) listed in Figure 1 to paragraph (g) of 
this AD, upgrade any EEC software standards earlier than SCN 5B/I or 
replace the EEC with a part eligible for installation at the next 
engine shop visit, or before December 1, 2018, whichever occurs 
first.
    (2) For an engine with an EEC model number EEC104-40 or EEC104-
60 and an S/N not listed in Figure 1 to paragraph (g) of this AD, 
upgrade any EEC software standards earlier than SCN 5B/I or replace 
the EEC with a part eligible for installation at the next engine 
shop visit, or before July 1, 2024, whichever occurs first.
    (3) For an engine with an EEC model number EEC104-1 with PN 
1B7484, 1B7486, 1B7984, or 1B7985, upgrade any EEC software 
standards earlier than SCN 27A or replace the EEC with a part 
eligible for installation at the next engine shop visit, or before 
July 1, 2024, whichever occurs first.
