Airworthiness Directives; Pacific 

Aerospace Limited Airplanes 

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 Pacific Aerospace Limited 

Model 750XL airplanes. This proposed 

AD was prompted by mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country to identify 

and correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as chafing damage 

in the port wing skin caused by the fuel 

system finger filters. This proposed AD 

would require inspecting the wing 

internal skin for chafing and taking any 

necessary corrective actions. The FAA is 

proposing this AD to address the unsafe 

condition on these products.

Background 

The Civil Aviation Authority (CAA), 

which is the aviation authority for New 

Zealand, has issued AD No. DCA/ 

750XL/34, effective date February 7, 

2019 (referred to after this as ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Pacific Aerospace Limited 

Model 750XL airplanes. The MCAI 

states: 

DCA/750XL/34 is prompted by a report of 

finding chafing damage in the port wing skin 

caused by the fuel finger filters. The [CAA] 

AD is issued to introduce inspection and 

repair requirements with the issue of Pacific 

Aerospace Mandatory Service Bulletin (MSB) 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 142 / Wednesday, July 28, 2021 / Proposed Rules 40385 

PACSB/XL/099 issue 1, dated 16 January 

2019. 

The MCAI requires inspecting the 

wing internal skin for chafing and 

taking any necessary corrective actions. 

You may examine the MCAI in the AD 

docket at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2021–0603. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Pacific Aerospace 

Limited Mandatory Service Bulletin 

PACSB/XL/099, Issue 1, dated January 

16, 2019. The service information 

contains procedures for removing and 

modifying the inspection panel 

assembly, inspecting the wing internal 

skin for chafing, repairing any chafing 

damage and replacing the fuel filter as 

necessary, and reinstalling the 

inspection panel assembly. 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 this State of 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI and service information 

referenced above. The FAA is issuing 

this NPRM after determining 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 

accomplishing the actions specified in 

the service information already 

described. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 23 

airplanes of U.S. registry. The FAA also 

estimates that it would take about 5 

work-hours per airplane to do the 

inspection and modification 

requirements of this proposed AD, and 

no parts would be necessary. Based on 

these figures, the FAA estimates the cost 

of the inspection and modification for 

U.S. operators to be $9,725, or $425 per 

product. 

In addition, the FAA estimates that 

any necessary follow-on actions for 

repair or replacement requirements of 

this proposed AD would take about 6 

work-hours and require parts costing 

$150, for a cost of $660 per airplane. 

The FAA has no way of determining the 

number of airplanes that may need these 

actions. 

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.

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: 

Pacific Aerospace Limited: Docket No. FAA– 

2021–0603; Project Identifier 2019–CE– 

006–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by September 

13, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Pacific Aerospace

originated by an aviation authority of another 

country to identify and address an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as chafing 

damage in the port wing skin caused by the 

fuel system finger filters. The FAA is issuing 

this AD to detect and correct chafing in the 

left hand (LH) wing leading edge tank skin, 

which if not detected and corrected, could 

result in a port wing fuel leak and lead to 

engine failure or fire. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

Within 165 hours time-in-service after the 

effective date of this AD, modify the LH 

inspection panel assembly and inspect the 

LH wing and fuel tank for chafing, and then, 

before further flight, repair any chafing and 

install the panels in accordance with the 

Accomplishment Instructions in Pacific 

Aerospace Limited Mandatory Service 

Bulletin PACSB/XL/099, Issue 1, dated 

January 16, 2019.
