DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2016-4231; Directorate Identifier 2015-CE-042-AD; 
Amendment 39-18537; AD 2016-11-10]
RIN 2120-AA64


Airworthiness Directives; BLANIK LIMITED Gliders

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: <a href="https://www.regulations.gov/#!documentDetail">https://www.regulations.gov/#!documentDetail</a>;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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (81 FR 11134, March 3, 2016) for correcting the unsafe condition; 
and
    <bullet> 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

[[Page 35582]]

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 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.

reference, Safety.

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

2016-11-10 BLANIK LIMITED: Amendment 39-18537; Docket No. FAA-2016-
4231; Directorate Identifier 2015-CE-042-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective July 8, 
2016.

(b) Affected ADs

    This AD supersedes 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
