13838 Federal Register / Vol. 86, No. 46 / Thursday, March 11, 2021 / Proposed Rules 

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. 

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 airworthiness 

directive: 

Airbus SAS: Docket No. FAA–2021–0140; 

Project Identifier MCAI–2020–01531–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) action by April 

26, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to the Airbus SAS 

airplanes specified in paragraphs (c)(1) 

through (6) of this AD, certificated in any 

category, as identified in European Union 

Aviation Safety Agency (EASA) AD 2020– 

0255, dated November 13, 2020 (EASA AD

(6) Model A340–642 airplanes. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 25, Equipment/furnishings. 

(e) Reason 

This AD was prompted by reports that, for 

certain lower deck mobile crew rest (LDMCR) 

units, the connection of a certain halon outlet 

tube to the outlet of a certain fire 

extinguisher bottle may be incorrect. The 

FAA is issuing this AD to address this 

condition, which, in case of a fire inside the 

LDMCR, could lead to disconnection of the 

tube, possibly resulting in reduced 

concentration of fire suppressing agent at any 

location inside the LDMCR. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, EASA AD 2020–0255. 

(h) Exceptions to EASA AD 2020–0255 

(1) Where EASA AD 2020–0255 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(2) The ‘‘Remarks’’ section of EASA AD 

2020–0255 does not apply to this AD. 

(i) No Reporting Requirement 

Although the service information 

referenced in EASA AD 2020–0255 specifies 

to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Large Aircraft 

Section, International Validation Branch, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. In accordance with 

14 CFR 39.19, send your request to your 

principal inspector or responsible Flight 

Standards Office, as appropriate. If sending 

information directly to the Large Aircraft

Background 

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. 2020–0202, dated September 22, 

2020 (referred to after this as ‘‘the 

MCAI’’), to correct an unsafe condition 

for Pilatus Model PC–24 airplanes. The 

MCAI states: 

The airworthiness limitations and 

certification maintenance instructions for 

Pilatus PC–24 aeroplanes, which are 

approved by EASA, are currently defined and 

published in Pilatus PC–24 AMM [Aircraft 

Maintenance Manual] Chapter 04–00–00. 

These instructions have been identified as 

mandatory for continued airworthiness. 

Failure to accomplish these instructions 

could result in an unsafe condition. 

Previously, EASA issued AD 2020–0074, 

[dated March 27, 2020,] requiring the actions 

described in the Pilatus PC–24 AMM Chapter 

04–00–00, Document Number 02378 Issue 

005 at Revision 14. 

Since that AD was issued, Pilatus 

published the ALS [Airworthiness 

Limitations section, at Issue 005 Revision 

19], which contains the following new and/ 

or more restrictive tasks as specified in 

Mandatory Structural Inspection Items data 

module PC24–AA04–20–0000–00A–000A–A 

Issue 005 Revision 00: 

—AL–27–00–025 and AL–27–00–026: 

Control column sprocket gear assembly, 

and 

—AL–27–00–027: Control wheel column 

assembly. 

In addition, Airworthiness Limitations 

Description data module PC24–A–A04–00– 

0000–00A–040A–A Issue 008 Revision 00 

includes: 

—The new limit of validity following the 

completion of the Full Scale Fatigue Test, 

and 

—Usage assumptions/conditions for 

operations on unpaved and grass 

runaways. 

EASA AD No. 2020–0074, dated 

March 27, 2020, required revising the 

Airworthiness Limitations section (ALS) 

to correct an error in the horizontal 

stabilizer primary trim system 

secondary power source operational 

test. The MCAI retains the requirements 

of EASA AD No. 2020–0074, dated 

March 27, 2020, which the MCAI 

supersedes, and requires the additional 

revisions discussed previously. You 

may examine the MCAI at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2020– 

0812. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Chapter 4, 

Airworthiness Limitations, of Pilatus 

PC–24 Aircraft Maintenance Manual, 

data module PC24–A–A04–00–0000– 

00A–040A–A, Issue 008, Revision 00, 

dated May 26, 2020. This service 

information contains the parent data 

module and the new limit of validity 

and updates the usage assumptions and 

conditions for operations on unpaved 

and grass runways. This document also 

contains the revised subsections with 

revised maintenance actions. 


khammond on DSKJM1Z7X2PROD with PROPOSALS
13840 Federal Register / Vol. 86, No. 46 / Thursday, March 11, 2021 / Proposed Rules 

The FAA also reviewed Pilatus PC–24 

Aircraft Maintenance Manual 

Horizontal stabilizer primary trim 

system secondary power source— 

Operation test, data module PC24–A– 

E27–40–0000–01A–320A–A, Issue 007, 

Revision 00, dated September 25, 2019. 

This service information contains 

revised procedures for task number AL– 

27–40–022 in the CMR. 

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 our 

bilateral agreement with this State of 

Design Authority, it has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. 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. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

replacing the revised sections of the 

ALS described previously into the 

existing AMM or instructions for 

continued airworthiness. Updating the 

entire ALS, including all subsections 

and referenced data modules, would be 

acceptable for compliance with this 

proposed AD. An owner/operator (pilot) 

may incorporate the ALS revisions, and 

the owner/operator must enter 

compliance with the applicable 

paragraphs of the AD into the aircraft 

records in accordance with 14 CFR 

43.9(a)(1) through (4) and 14 CFR 

91.417(a)(2)(v). This is an exception to 

our standard maintenance regulations. 

Costs of Compliance 

The FAA estimates that this proposed 

AD would affect 42 products of U.S. 

registry. The FAA also estimates that it 

would take about 1 work-hour per 

product to comply with the 

requirements of this proposed AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, the FAA 

estimates the cost of the proposed AD 

on U.S. operators would be $3,570 or 

$85 per product. 

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) 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. 

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 airworthiness 

directive: 

Pilatus Aircraft Ltd.: Docket No. FAA–2020– 

0812; Project Identifier MCAI–2020– 

01317–A. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by April 26, 

2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Pilatus Aircraft Ltd. 

Model PC–24 airplanes, all serial numbers, 

certificated in any category. 

(d) Subject 

Joint Aircraft System Component (JASC) 

Code 2740: Stabilizer Control System. 

(e) Reason 

This AD was prompted by the need to 

revise the Airworthiness Limitations section 

(ALS) of the existing aircraft maintenance 

manual (AMM) to add new and more 

restrictive tasks for the control column 

sprocket gear assembly and control wheel 

column assembly, to address the new limit of 

validity and update the usage assumptions 

and conditions for operations on unpaved 

and grass runways, and to correct an error in 

the horizontal stabilizer primary trim system 

secondary power source operational test. The 

FAA is issuing this AD to prevent reduction 

in the structural integrity of the airframe and 

components, as well as an unrecognized 

failure of the manual pitch trim. These 

conditions, if not addressed, could result in 

loss of airplane control. 

(f) Actions and Compliance 

(1) Before further flight, unless already 

done, revise the ALS of the existing AMM or 

instructions for continued airworthiness 

(ICA) for your airplane by incorporating the 

following documents.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Airbus Defense and Space S.A. 

Model C–212–CB, C–212–CC, C–212– 

CD, C–212–CE, C–212–CF, C–212–DE, 

and C–212–DF airplanes. This proposed 

AD was prompted by a report of cracks 

on the left-hand (LH) and right-hand 

(RH) side fuselage skin and on frame 

(FR) 5 underneath the skin, near the 

leading edge of the wing. This proposed 

AD would require repetitive inspections 

of the LH and RH side center wing 

fairings at FR 5, around the wing 

leading edge for discrepancies (cracks) 

and repair, as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is proposed for incorporation 

by reference. The FAA is proposing this 

AD to address the unsafe condition on 

these products.
