AD 2019-03-02

We are adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 an incorrect size bolt may have been used to assemble the elevator bellcrank pivot joint. We are issuing this AD to require actions to address the unsafe condition on these products.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 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 (AD):

2019-03-02 Pacific Aerospace Limited: Amendment 39-19554; Docket No.
FAA-2018-0385; Product Identifier 2018-CE-019-AD.

(a) Effective Date

This AD becomes effective March 28, 2019.

(b) Affected ADs

None.

(c) Applicability

This AD applies to Pacific Aerospace Limited Model 750XL airplanes, all serial numbers through 215, certificated in any category.

(d) Subject

Air Transport Association of America (ATA) Code 27: Flight Controls.

(e) Reason

This 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. We are issuing this AD to prevent damage from the threads of the bolt on the internal bore of the cross tube hinge plate, which could result in reduced control.

(f) Actions and Compliance

Unless already done, do the following actions in paragraphs (f)(1) and (2) of this AD:
(1) Within the next 150 hours time-in-service after March 28, 2019 (the effective date of this AD) or within the next 12 months after March 28, 2019 (the effective date of this AD), whichever occurs later, inspect the elevator bellcrank pivot joint to determine the length and the part number (P/N) of the bolt installed. Do the inspection using the Inspection Instructions, steps 1 through 3, in Pacific Aerospace Service Bulletin PACSB/XL/ 097, Issue 1, dated March 12, 2018.
(2) If you determine bolt, P/N AN4-20, is installed during the inspection required inparagraph (f)(1) of this AD, before further flight, take all necessary corrective actions using the Accomplishment Instructions in Pacific Aerospace Service Bulletin PACSB/XL/097, Issue 1, dated March 12, 2018.

(g) Other FAA AD Provisions

The following provisions also apply to this AD:

[[Page 5352]]

(1) Alternative Methods of Compliance (AMOCs): The Manager, Small Airplane Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Pacific Aerospace Limited Model 750XL airplanes. The NPRM was published in the Federal Register on May 11, 2018 (83 FR 21951). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by the Civil Aviation Authority (CAA), which is the aviation authority of New Zealand. The MCAI states:

It is possible that the elevator bellcrank pivot joint could be assembled with a bolt P/N AN4-20 that is a little too short, leaving threads inside the working area of the section of the joint.

The MCAI requires inspecting the elevator bellcrank pivot joint to determine the length of the bolt installed to determine if it is the proper size and taking all necessary corrective actions. The MCAI can be found in the AD docket on the internet at: https://www.regulations.gov/document?D=FAA-2018-03850-002.
Incorrectly sized bolts that are too short can cause damage from the threads of the bolt on the internal bore of the cross tube hinge plate, which could result in reduced control.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes and changes to clarify the incorporation by reference of the service information. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51We reviewed Pacific Aerospace Limited Service Bulletin PACSB/XL/ 097, Issue 1, dated March 12, 2018. The service information describes procedures for inspecting the elevator bellcrank pivot joint to determine if the correct bolt size is installed. If an incorrect size bolt is found, the service bulletin describes procedures for inspecting the cross tube to confirm structural integrity, taking necessary corrective actions, and replacing the incorrect size bolt with a correct sized bolt. 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.

Costs of Compliance

We estimate that this AD will affect 22 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost ofthis AD on U.S. operators to be $3,740, or $170 per product.
In addition, we estimate that any necessary follow-on actions would take about 8 work-hours and require parts costing $125, for a cost of $805 per product. We have no way of determining the number of products that may need these actions.
According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.

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.
We are 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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes, gliders, balloons, airships, domestic business jet transport airplanes, and associated appliances to the Director of the Policy and Innovation Division.

Regulatory Findings

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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 AD:
(1) Is not a ``significant regulatory action'' under Executive Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
