AD 2015-25-07

We are superseding Airworthiness Directive (AD) 2008-09-01 for certain Alpha Aviation Concept Limited Model R2160 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 a need to revise the maintenance program to include the revised airworthiness limitations for the internal wing structure and wing attachment inspections. 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 removing Amendment 39-15481 (73 FR 21519, April 22, 2008) and adding the following new AD:

2015-25-07 Alpha Aviation Concept Limited: Amendment 39-18345; Docket No. FAA-2015-3956; Directorate Identifier 2015-CE-032-AD.

(a) Effective Date

This airworthiness directive (AD) becomes effective January 25, 2016.

(b) Affected ADs

This AD supersedes AD 2008-09-01, Amendment 39-15481 (73 FR 21519, April 22, 2008) (``AD 2008-09-01'').

(c) Applicability

This AD applies to Alpha Aviation Concept Limited Model R2160 airplanes, serial numbers (S/Ns) 001 through 378, and 160A-06001 and subsequent, certificated in any category.

(d) Subject

Air Transport Association of America (ATA) Code 5: Time Limits.

(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. The MCAI describes the unsafe condition as a need to revise the maintenance program to include the revised airworthiness limitations for the internal wing structure and wing attachment inspections. We are issuing this AD to prevent failure of the wing structure and fuselage attachment due to undetected fatigue and corrosion.

(f) Actions and Compliance

Unless already done, before further flight after January 25, 2016 (the effective date of this AD), insert the following into the Airworthiness Limitations section of the FAA-approved maintenance program (e.g., maintenance manual). These revisions to the Limitations sections incorporatethe wing spar inspection upon the accumulation of 3,500 hours time-in-service (TIS) and require a repetitive inspection thereafter every 750 hours TIS (the requirements of AD 2008-09-01):
(1) For S/Ns 001 through 378: Insert paragraph 3.4.9, Wing 3500 hr Inspection, on pages 3-3 and 3-4, dated August 2015, of Section 3: Airworthiness Limitations, Time Limits, & Maintenance Inspections, dated August 2015, of the APEX R2000 Service Manual S/N 001 to 378, Alpha Aviation Ltd.
(2) For S/Ns 160A-06001 and subsequent: Insert paragraph 3.4.9, Wing 3500 hr Inspection, on pages 3-3 and 3-4, dated August 2015, of Section 3: Airworthiness Limitations, Time Limits, & Maintenance Inspections, all dated August 2015, of the R2000 Service Manual, Alpha Aviation Ltd.

(g) Other FAA AD Provisions

The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requestedusing the procedures found in 14 CFR 39.19. Send information to ATTN: Karl Schletzbaum, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4146; fax: (816) 329-4090; email: karl.schletzbaum@faa.gov. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent).

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Alpha Aviation Concept Limited Model R2160 airplanes. That NPRM was published in the Federal Register on September 25, 2015 (80 FR 57753), and proposed to supersede AD 2008-09-01, Amendment 39-15481 (73 FR 21519, April 22, 2008).
Since we issued AD 2008-09-01, Amendment 39-15481 (73 FR 21519, April 22, 2008), Alpha Aviation Concept Limited developed a longer life limit for the wing structure and wing attachments and transferred the life limit information from the related service information to the airplane maintenance manual. Subsequently, Alpha Aviation Concept Limited discovered that the analysis that allowed the life limit increase was incorrect and the previous life limit and inspection provisions of the related service bulletin should be retained.
The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The Civil Aviation Authority (CAA), which is the aviation authority for New Zealand, has issued AD DCA/R2000/43, dated August 7, 2015 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states that:

This AD introduces a change to the airworthiness limitations for the internal wing structure and wing attachment inspections. These inspection intervals were increased and added to Section 3.2-- Airworthiness Limitations of the applicable Service Manual in January 2015. Section 3.2 of the respective Service Manuals has now been revised to revert to the original inspection intervals.

You may examine the MCAI on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-3956-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 57753, September 25, 2015) 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. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM (80 FR 57753, September 25, 2015) for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 57753, September 25, 2015).

Related Service Information Under 1 CFR Part 51

Alpha Aviation Concept Limited has revised its Alpha Aviation APEX R2000 Service Manual, S/N 001 to 378, and Alpha Aviation R2000 Service Manual. The updated service manuals include a revision to Section 3: Airworthiness Limitations, Time Limits, & Maintenance Inspections, Issued August 2015, that adds periodic internal wing structureand wing attachment inspections. These revisions to the Airworthiness Limitations section of the applicable service manuals are reasonably available because the interested parties have access to them 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 9 products of U.S. registry. We also estimate that it will take about 3 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 of this AD on U.S. operators to be $2,295, or $255 per product.
In addition, we estimate that any necessary follow-on actions will take about 12 work-hours and require parts costing $1,326, for a cost of $2,346 per product. We have no way of determining the number of products 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.
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

[[Page 79257]]

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

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 therelationship 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.
