We propose to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Division (PW) PW2037, PW2037M, and PW2040 turbofan engines. This proposed AD was prompted by an unrecoverable engine in-flight shutdown (IFSD) after an ice crystal icing event. This proposed AD would require installing a software standard eligible for installation and preclude the use of electronic engine control (EEC) software standards earlier than SCN 5B/I. We are proposing this AD to correct the unsafe condition on these products.

Airworthiness Directives; Pratt & Whitney Division Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Pratt & Whitney Division (PW) PW2037, PW2037M, and PW2040 
turbofan engines. This proposed AD was prompted by an unrecoverable 
engine in-flight shutdown (IFSD) after an ice crystal icing event. This 
proposed AD would require installing a software standard eligible for 
installation and preclude the use of electronic engine control (EEC) 
software standards earlier than SCN 5B/I. We are proposing this AD to 
correct the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this NPRM. Send your comments to an address listed 
under the section. Include ``Docket No. FAA-2016-9405; Directorate 
Identifier 2016-NE-22-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this NPRM. We will consider all

Discussion

    We propose to adopt an AD for certain PW PW2037, PW2037M, and 
PW2040 turbofan engines with EEC, model number EEC104-40 or EEC104-60, 
installed with an EEC software standard earlier than SCN 5B/I. This 
proposed AD was prompted by a report of an unrecoverable engine IFSD 
after an ice crystal icing event. The root cause of the event is ice 
crystal icing causing the engine to flameout. An attempt to restart the 
engine was made while the active clearance control was on, which caused 
damage to the HPT and rotor seizure. This condition, if not corrected, 
could result in failure of the HPT, rotor seizure, failure of one or 
more engines, loss of thrust control, and loss of the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed PW Alert Service Bulletin (ASB) PW2000 A73-170, dated 
July 14, 2016. The ASB describes

[[Page 1266]]

procedures for modifying or replacing the EEC. 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 section.

FAA's Determination

    We are proposing this NPRM 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 require modifying or replacing the EEC.

Differences Between This Proposed AD and the Service Information

    PW ASB PW2000 A73-170, dated July 14, 2016, specifies compliance 
for any engine flown, or expected to be flown, in the Asian Pacific 
latitudes and longitudes, while this proposed AD specifically lists the 
serial numbers (S/Ns) of certain affected engines. Also, PW ASB PW2000 
A73-170, dated July 14, 2016, provides until 2026 to comply, while this 
proposed AD provides until July 2024 to comply.

Costs of Compliance

    We estimate that this NPRM affects 713 engines, installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

                                      hour = $153.00.
----------------------------------------------------------------------------------------------------------------

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.

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
