E:\FR\FM\23OCP1.SGM 23OCP1 67466 Federal Register / Vol. 85, No. 206 / Friday, October 23, 2020 / Proposed Rules Discussion The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2020–0096, dated April 29, 2020 (referred to after this as the mandatory continuing airworthiness information, or ‘‘the MCAI’’), to correct an unsafe condition for all Pilatus Model PC–24 airplanes. The MCAI states an occurrence was reported where some ECBs were found in a locked state after maintenance, but before flight. This situation caused the airplane to have a loss of equipment power before take-off and the pilot had no indication of this situation. This was caused by maintenance personnel turning off some or all of the ECBs through the cockpit multi-function display (MFD) prior to performing maintenance and then incorrectly or improperly resetting the ECBs when the maintenance is complete. Currently, there is no procedure in the airplane flight manual (AFM) to check whether the ECBs have been correctly set other than a step in the AFM ‘‘Before Engine Start’’ section that checks whether any ECBs are ‘‘FAILED’’ or ‘‘TRIPPED.’’ Pilatus has issued a temporary revision to the AFM to replace the ‘‘Before Engine Start’’ step to check for ECBs that are ‘‘FAILED, TRIPPED or LOCKED.’’ This added procedure will help ensure that there is indication to the pilot of the status of equipment power supply before take-off. According to the MCAI, this condition, if not corrected, could lead to a loss of power supply to equipment, without indication to the flightcrew before take-off. To address this condition, the MCAI requires amending the AFM to include a temporary revision issued by Pilatus to provide operators with the necessary preflight check instructions. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2020– 0917. Related Service Information Under 1 CFR Part 51 Pilatus has issued PC–24 (Pilatus) Temporary Revision No. 02371–016, dated November 1, 2019, to the PC–24 AFM. This service information contains a step to be added to the pilot preflight procedures to check the ECB status. 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 This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI and service information referenced above. The FAA is proposing this AD because the FAA evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed Requirements of This NPRM This proposed AD would require revising the airplane flight manual to incorporate a pilot preflight procedure to check the ECB status. Costs of Compliance The FAA estimates that this proposed AD would affect 30 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: khammond on DSKJM1Z7X2PROD with PROPOSALS ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $2,550 Authority for This Rulemaking Regulatory Findings The Proposed Amendment 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. 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. 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) Will not affect intrastate aviation in Alaska, and (3) 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. Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: VerDate Sep<11>2014 18:07 Oct 22, 2020 Jkt 253001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Discussion

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD No. 2020-0096, dated April 29, 2020 (referred to after this as 
the mandatory continuing airworthiness information, or ``the MCAI''), 
to correct an unsafe condition for all Pilatus Model PC-24 airplanes. 
The MCAI states an occurrence was reported where some ECBs were found 
in a locked state after maintenance, but before flight. This situation 
caused the airplane to have a loss of equipment power before take-off 
and the pilot had no indication of this situation. This was caused by 
maintenance personnel turning off some or all of the ECBs through the 
cockpit multi-function display (MFD) prior to performing maintenance 
and then incorrectly or improperly resetting the ECBs when the 
maintenance is complete. Currently, there is no procedure in the 
airplane flight manual (AFM) to check whether the ECBs have been 
correctly set other than a step in the AFM ``Before Engine Start'' 
section that checks whether any ECBs are ``FAILED'' or ``TRIPPED.'' 
Pilatus has issued a temporary revision to the AFM to replace the 
``Before Engine Start'' step to check for ECBs that are ``FAILED, 
TRIPPED or LOCKED.'' This added procedure will help ensure that there 
is indication to the pilot of the status of equipment power supply 
before take-off.
    According to the MCAI, this condition, if not corrected, could lead 
to a loss of power supply to equipment, without indication to the 
flightcrew before take-off. To address this condition, the MCAI 
requires amending the AFM to include a temporary revision issued by 
Pilatus to provide operators with the necessary preflight check 
instructions.
    You may examine the MCAI in the AD docket on the internet at 
https://www.regulations.gov by searching for and locating Docket No. 
FAA-2020-0917.

Related Service Information Under 1 CFR Part 51

    Pilatus has issued PC-24 (Pilatus) Temporary Revision No. 02371-
016, dated November 1, 2019, to the PC-24 AFM. This service information 
contains a step to be added to the pilot preflight procedures to check 
the ECB status. 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

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
and service information referenced above. The FAA is proposing this AD 
because the FAA evaluated all the relevant information and determined 
the unsafe condition described previously is likely to exist or develop 
on other products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require revising the airplane flight manual 
to incorporate a pilot preflight procedure to check the ECB status.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 30 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.
    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) Will not affect intrastate aviation in Alaska, and
    (3) 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

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.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Pilatus Aircraft Ltd.: Docket No. FAA-2020-0917; Project Identifier 
MCAI-2020-00606-A.

(a) Comments Due Date

    The FAA must receive comments by December 7, 2020.

(b) Affected ADs

    None.

[[Page 67467]]

(c) Applicability

    This airworthiness directive (AD) applies to Pilatus Aircraft 
Ltd. Model PC-24 airplanes, all serial numbers, certificated in any 
category.

(d) Subject

    Air Transport Association (ATA) of America Code 24, Electrical 
Power.

(e) Reason

    This AD was prompted by a report that electronic circuit 
breakers (ECBs) were found in a locked state after maintenance, but 
before flight. ECBs were turned off prior to maintenance and then 
not reset properly after maintenance was complete. The FAA is 
issuing this AD to prevent improperly set ECBs, which if not 
detected, could lead to loss of power supply to equipment without 
indication to the flightcrew before take-off.

(f) Compliance

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

(g) Revision of the Airplane Flight Manual (AFM)

    Within 30 days after the effective date of this AD, revise 
Section 4 of the existing AFM for your airplane by replacing the 
information as specified in PC-24 (Pilatus) Temporary Revision No. 
02371-016, dated November 1, 2019, to the Pilatus PC-24 AFM.

(h) Alternative Methods of Compliance (AMOCs)

    The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. Send information to: Doug Rudolph, 
Aerospace Engineer, FAA, General Aviation & Rotorcraft Section, 
International Validation Branch, 901 Locust Street, Room 301, Kansas 
City, Missouri 64106; telephone: (816) 329-4059; fax: (816) 329-
4090; email: [email protected]. In accordance with 14 CFR 39.19,
