Airworthiness Directives; BLANIK LIMITED Gliders

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

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for BLANIK LIMITED Models L-13 Blanik and L-13 AC Blanik gliders (type certificate previously held by LET Aeronautical Works) that would supersede AD 2000-20-11. This proposed AD results from 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 insufficient material strength of the tail-fuselage attachment fitting. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by April 18, 2016.

ADDRESSES: You may send comments by any of the following methods:

SUPPLEMENTARY INFORMATION:

Comments Invited

We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2016-4231; Directorate Identifier 2015-CE-042-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments.

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

Discussion

On September 28, 2000, we issued AD 2000-20-11, Amendment 39-11922 (65 FR 60845; October 13, 2000) (``AD 2000-20-11''). That AD required actions intended to address an unsafe condition on BLANIK LIMITED Model L-13 Blanik gliders and was based on mandatory continuing airworthiness information (MCAI) originated by the Civil Aviation Authority, which is the aviation authority for the Czech Republic. That MCAI (AD CAA-AD-T-

112/1999R1, dated November 23, 1999), was issued to correct an unsafe condition for EVECTOR, spol. s.r.o. Models L 13 SEH VIVAT and L 13 SDM VIVAT gliders and BLANIK LIMITED Models L-13 Blanik and L-13 AC Blanik gliders. The MCAI states:

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.

You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-

4231.

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

The FAA will address the EVECTOR, spol. s.r.o. Model L 13 SDM VIVAT gliders in another AD action.

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 this NPRM.

FAA's Determination and Requirements of the Proposed 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 proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

Costs of Compliance

We estimate that this proposed 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 proposed AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the proposed 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 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 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 proposed AD would not have federalism implications

Page 11136

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) 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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

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

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 39-11922 (65 FR 60845; October 13, 2000), and adding the following new AD:

Blanik Limited: Docket No. FAA-2016-4231; Directorate Identifier 2015-CE-042-AD.

(a) Comments Due Date

We must receive comments by April 18, 2016.

(b) Affected ADs

This AD replaces AD 2000-20-11, Amendment 39-11922 (65 FR 60845; October 13, 2000) (``AD 2000-20-11'').

(c) Applicability

This AD applies to BLANIK LIMITED Models L-13 Blanik and L-13 AC Blanik gliders (type certificate previously held by LET Aeronautical Works), all serial numbers, certificated in any category.

(d) Subject

Air Transport Association of America (ATA) Code 53: Fuselage.

(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 insufficient material strength of the tail-fuselage attachment fitting. We are issuing this AD to detect and correct tail-fuselage fittings with insufficient material strength, which if left uncorrected could result in detachment of the tail from the fuselage with consequent loss of control.

(f) Actions and Compliance

Unless already done, do the following actions in paragraphs (f)(1) and (f)(2) of this AD, including all subparagraphs:

(1) Model L-13 Blanik gliders:

(i) Within the next 60 days after November 27, 2000 (the effective date retained from AD 2000-20-11), inspect the tail-

fuselage attachment fitting, part number (P/N) A 102 021 N, for damage and material hardness following the procedures in LET Mandatory Bulletin No.: L13/085a, dated November 17, 1999.

(ii) If you find the tail-fuselage attachment fitting is damaged or the material does not meet the hardness requirements specified in the service bulletin during the inspection required in paragraph (f)(1)(i) of this AD, before further flight, you must contact the manufacturer to obtain an FAA-approved replacement part for P/N A 102 021 N and FAA-approved installation instructions and install the replacement part. Use the contact information found in paragraph (h) to contact the manufacturer.

(iii) As of November 27, 2000 (the effective date retained from AD 2000-20-11), do not install, on any glider, a P/N A 102 021 N attachment fitting that has not passed the inspection required in paragraph (f)(1)(i) of this AD.

(2) Model L-13 AC Blanik gliders:

(i) Within the next 60 days after the effective date of this AD, inspect the tail-fuselage attachment fitting, part number (P/N) A 102 021 N, for damage and material hardness following the procedures in LET Mandatory Bulletin No.: L13/085a, dated November 17, 1999.

(ii) If you find the tail-fuselage attachment fitting is damaged or the material does not meet the hardness requirements specified in the service bulletin during the inspection required in paragraph (f)(2)(i) of this AD, before further flight, you must contact the manufacturer to obtain an FAA-approved replacement part for P/N A 102 021 N and FAA-approved installation instructions and install the replacement part. Use the contact information found in paragraph (h) to contact the manufacturer.

(iii) As of the effective date of this AD, do not install, on any glider, a P/N A 102 021N attachment fitting that has not passed the inspection required in paragraph (f)(2)(i) of this AD.

(g) Other FAA AD Provisions

The following provisions also apply to this AD:
