We propose to supersede Airworthiness Directive (AD) 2017-12- 03, which applies to certain Pratt & Whitney Division (PW) PW2037, PW2037M, and PW2040 turbofan engines. AD 2017-12-03 requires installing a software standard eligible for installation and precludes the use of electronic engine control (EEC) software standards earlier than SCN 5B/ I. Since we issued AD 2017-12-03, software became available for additional PW engines models. This proposed AD would require installing a software standard eligible for installation and preclude the use of EEC software standards earlier than SCN 5B/I or SCN 27A. We are proposing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2017-12-
03, which applies to certain Pratt & Whitney Division (PW) PW2037,

[[Page 59558]]

PW2037M, and PW2040 turbofan engines. AD 2017-12-03 requires installing 
a software standard eligible for installation and precludes the use of 
electronic engine control (EEC) software standards earlier than SCN 5B/
I. Since we issued AD 2017-12-03, software became available for 
additional PW engines models. This proposed AD would require installing 
a software standard eligible for installation and preclude the use of 
EEC software standards earlier than SCN 5B/I or SCN 27A. We are 
proposing this AD to address the unsafe condition on these products.

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:

                                         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.
