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 installation of 

the wing leading edge tank fuel pickup 

assembly in a pre-stressed condition, 

which could cause cracks in the wing 

spar web or the fuel pickup assembly 

pipe. This proposed AD would require 

inspecting the angle of the support 

bracket on the wing leading edge tank 

fuel pickup assembly and taking any 

necessary corrective actions. The FAA is 

proposing this AD to address the unsafe 

condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by September 7, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Background 

The Civil Aviation Authority (CAA), 

which is the aviation authority for New 

Zealand, has issued AD No. DCA/ 


lotter on DSK11XQN23PROD with PROPOSALS1
38616 Federal Register / Vol. 86, No. 138 / Thursday, July 22, 2021 / Proposed Rules 

750XL/36, 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/36 is prompted by a review of 

the installation of the wing leading edge fuel 

pickup assemblies. It was found that the fuel 

pickup assemblies could have been installed 

in a pre-stressed condition, which could 

result in cracks in the wing spar web, or 

cracks in the fuel pickup pipe. The [CAA] AD 

is issued to introduce the instructions in 

Pacific Aerospace Mandatory Service 

Bulletin (MSB) PACSB/XL/109 issue 1, dated 

16 January 2019. 

The MCAI requires inspecting the 

installation of the fuel pickup assembly 

and the wing spar web on both wings 

and, if any defects are found, taking all 

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–2021–0576. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Pacific Aerospace 

Mandatory Service Bulletin PACSB/XL/ 

109, Issue 1, dated January 16, 2019. 

The service information contains 

procedures for inspecting the wing 

leading edge tank fuel pickup assembly 

to determine if the assembly is under 

stress and for additional inspections and 

corrective actions if necessary. 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 1 

work-hour per airplane to comply with 

the inspection that would be required 

by this proposed AD. The average labor 

rate is $85 per work-hour. 

Based on these figures, the FAA 

estimates the inspection cost of this 

proposed AD on U.S. operators to be 

$1,955, or $85 per airplane. 

In addition, the FAA estimates that 

any necessary follow-on actions would 

take 4 work-hours and require parts 

costing $500, for a cost of $840 per 

airplane. The FAA has no way of 

determining the number of airplanes 

that may need these actions. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. 

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– 

2021–0576; Project Identifier 2019–CE– 

008–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by September 7, 

2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Pacific Aerospace 

Limited Model 750XL airplanes, serial 

numbers 177, 186 through 213, 220, 8001, 

and 8002, certificated in any category. 

(d) Subject 

Joint Aircraft System Component (JASC) 

Code 3600, Pneumatic System. 

(e) Unsafe Condition 

This AD was prompted by mandatory 

continuing airworthiness information (MCAI) 

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 installation 

of the wing leading edge tank fuel pickup 

assembly in a pre-stressed condition, which 

could cause cracks in the wing spar web or 

the fuel pickup assembly pipe. The FAA is 

issuing this AD to prevent cracks in the wing 

spar web and the fuel pickup pipe. This 

condition could result in reduced structural 

integrity of the wing spar or cause a fuel leak, 

which could result in an engine 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, inspect the angle of
