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 Mark Taylor, Aviation Safety Engineer, ECO Branch, FAA, 1200 District Avenue, Burlington, MA 01803. 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 FAA was notified of an airplane that experienced an uncommanded dual engine shutdown upon landing, resulting in compromised braking capability due to the loss of engine power and hydraulic systems. A subsequent investigation determined that the sequence of the auto-throttle increasing throttle to maintain Mach number, immediately followed by pilot command to decrease throttle to idle, caused a transient disagreement between actual and commanded thrust. This disagreement triggered the thrust control malfunction (TCM) detection logic and resulted in dual engine shutdown once the weight on wheels signal was activated upon landing. The installed EEC FADEC software version latches the fault and allows the engine to continue operation as commanded but shuts down the engine upon landing. The manufacturer identified the situations that could trigger the TCM logic erroneously and updated the EEC FADEC software. This software update makes corrective improvements to the TCM logic, including revised criteria for triggering the TCM logic and establishing criteria that permit the TCM logic to unlatch during flight. This condition, if not addressed, could result in runway excursion. FAA’s Determination The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Related Service Information The FAA reviewed PW Service Bulletin (SB) PW1000G–A–73–00– 0054–00A–930A–D, Issue No. 002, dated June 20, 2022. This service information specifies procedures for replacing or modifying the EEC to incorporate FADEC software version V2.11.14. Proposed AD Requirements in This NPRM This proposed AD would require removal from service of certain EEC FADEC software versions and replacement with a software version eligible for installation. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 147 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: khammond on DSKJM1Z7X2PROD with PROPOSALS ESTIMATED COSTS Action Labor cost Upgrade EEC FADEC Software ..................... 2 work-hours × $85 per hour = $170 .............

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 Mark 
Taylor, Aviation Safety Engineer, ECO Branch, FAA, 1200 District 
Avenue, Burlington, MA 01803. 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 FAA was notified of an airplane that experienced an uncommanded 
dual engine shutdown upon landing, resulting in compromised braking 
capability due to the loss of engine power and hydraulic systems. A 
subsequent investigation determined that the sequence of the auto-
throttle increasing throttle to maintain Mach number, immediately 
followed by pilot command to decrease throttle to idle, caused a 
transient disagreement between actual and commanded thrust. This 
disagreement triggered the thrust control malfunction (TCM) detection 
logic and resulted in dual engine shutdown once the weight on wheels 
signal was activated upon landing. The installed EEC FADEC software 
version latches the fault and allows the engine to continue operation 
as commanded but shuts down the engine upon landing. The manufacturer 
identified the situations that could trigger the TCM logic erroneously 
and updated the EEC FADEC software. This software update makes 
corrective improvements to the TCM logic, including revised criteria 
for triggering the TCM logic and establishing criteria that permit the 
TCM logic to unlatch during flight. This condition, if not addressed, 
could result in runway excursion.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Related Service Information

    The FAA reviewed PW Service Bulletin (SB) PW1000G-A-73-00-0054-00A-
930A-D, Issue No. 002, dated June 20, 2022. This service information 
specifies procedures for replacing or modifying the EEC to incorporate 
FADEC software version V2.11.14.

Proposed AD Requirements in This NPRM

    This proposed AD would require removal from service of certain EEC 
FADEC software versions and replacement with a software version 
eligible for installation.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 147 engines installed on airplanes of U.S. registry.
    The FAA estimates 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.

[[Page 64399]]

    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.
