AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding airworthiness directive (AD) 2000-20-11 for BLANIK LIMITED Models L-13 Blanik and L-13 AC Blanik gliders (type certificate previously held by LET Aeronautical Works). 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 insufficient material strength of the tail-fuselage attachment fitting. We are issuing this AD to require actions to address the unsafe condition on these products.

DATES:

This AD is effective July 8, 2016.

The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of November 27, 2000 (65 FR 60845, October 13, 2000).

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to BLANIK LIMITED Models L-13 Blanik and L-13 AC Blanik gliders. That NPRM was published in the Federal Register on March 3, 2016 (81 FR 11134), and proposed to supersede AD 2000-20-11, Amendment 39-11922 (65 FR 60845; October 13, 2000).

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 MCAI states that:

To prevent destruction of tail-fuselage attachment fitting which can lead to loss of control of the sailplane. This destruction could be caused due to lower strength of the material used during production.

The MCAI can be found in the AD docket on the Internet at: https://www.regulations.gov/​#!documentDetail;​D=​FAA-2016-4231-0003.

A review of records since issuance of AD 2000-20-11 revealed that the FAA inadvertently did not address this MCAI for the EVEKCTOR, spol. s.r.o. Model L 13 SDM VIVAT gliders and the BLANIK LIMITED Model L-13 AC Blanik gliders. This AD supersedes AD 2000-20-11 to add the BLANIK LIMITED Model L-13 AC Blanik gliders to the applicability of the AD.

The FAA is addressing the EVEKTOR, spol. s.r.o. Model L 13 SDM VIVAT gliders in another AD action.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (81 FR 11134, March 3, 2016) 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 (81 FR 11134, March 3, 2016) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (81 FR 11134, March 3, 2016).

Related Service Information Under 1 CFR Part 51

LET Aeronautical Works has issued LET Mandatory Bulletin No.: L13/085a, dated November 17, 1999. The service information describes procedures for testing the material strength of attachment fitting part number A 102 021 N and instructions for contacting the manufacturer for replacement information 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 of the AD.

Costs of Compliance

We estimate that this AD will affect 124 products of U.S. registry. We also estimate that it would take about 4 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 the AD on U.S. operators to be $42,160, or $340 per product.

In addition, we estimate that any necessary follow-on actions would take about 16 work-hours and require parts costing $500, for a cost of $1,860 per product. We have no way of Start Printed Page 35582determining 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 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 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.
