Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

We are adopting a new airworthiness directive (AD) for all Viking Air Limited Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes that supersedes AD 2016-19-08. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as corrosion of the elevator control rod and of the elevator actuating lever on the control column, which could cause these components to fail. We are issuing this AD to require actions to address the unsafe condition on these products.

DATES:

This AD is effective December 22, 2016.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 24, 2016 (81 FR 64053, September 19, 2016).

SUPPLEMENTARY INFORMATION:

Discussion

On September 8, 2016, we issued AD 2016-19-08, Amendment 39-18657 (81 FR 64053, September 19, 2016) (“AD 2016-19-08”). That AD required actions intended to address an unsafe condition on all Viking Air Limited (Viking) Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country.

There is a required action in AD 2016-19-08 to insert temporary revisions into the Airworthiness Limitations section of the FAA-approved maintenance program (e.g., maintenance manual). These revisions incorporate repetitive inspections of the elevator control rod assemblies, the elevator actuating lever, and the control column torque tube for corrosion, cracks, and/or other damage.

Viking Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes are not certified under 14 CFR part 23—Airworthiness Standards: Normal, Utility, Acrobatic, and Commuter Category Airplanes and the associated FAA-approved maintenance program (e.g., maintenance manual) does not include an Airworthiness Limitations section. Therefore, the requirement in AD 2016-19-08 to insert Temporary Revision No.: 2-38, dated March 4, 2015, and Temporary Revision No.: 2T-14, dated March 4, 2015, into the Airworthiness Limitations section of the applicable Viking Aircraft DHC-2 Maintenance Manual is not enforceable.

Relative Service Information Under 1 CFR Part 51

We reviewed Viking Air Limited DHC-2 Beaver Service Bulletin Number: V2/0005, Revision `C', dated July 17, 2015. This service information describes procedures for doing detailed visual inspections of the elevator control rod assemblies, the elevator actuating lever on the control column, and the control column torque tube for corrosion, cracking, and/or other damage. This service bulletin also describes procedures for repairing or replacing damaged parts. 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 of this AD.

FAA's Determination and Requirements of This AD

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, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because the way we addressed the actions in AD 2016-19-18 is unenforceable and the unsafe condition exists and is likely to exist or develop on other products of the same type design. The actions in this AD correct the unenforceability problem.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because we have already provided public notice on the intent of the actions in this AD. This AD only clarifies the repetitive inspection requirements of AD 2016-19-08 by correcting the means by which the repetitive inspections are done (in the AD versus maintenance manual). Therefore, we determined that notice and opportunity for public comment before issuing this AD are unnecessary.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2016-9527; Directorate Identifier 2016-CE-036” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Costs of Compliance

We estimate that this AD will affect 135 products of U.S. registry. We also estimate that it will take about 11.5 work-hours per product to comply with the basic inspection requirements of this AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the basic inspection requirements of this AD on U.S. operators to be $131,962.50, or $977.50 per product.

In addition, we estimate that any necessary follow-on actions will take about 8 work-hours and require parts costing $1,859, for a cost of $2,539 per product. Contact Viking Air Limited at the address identified in the ADDRESSES section of this AD for current pricing and lead time. We have no way of determining the number of products that may need these actions.

There is no estimated cost of compliance difference between this AD and AD 2016-19-08 since there is no change in the number of affected airplanes or in the required 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 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 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 that 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),Start Printed Page 93800

(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.
