Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD No.: 2016–0192, dated September 28, 2016 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: A temporary rudder control blockage was reported, involving an ASK 21 sailplane equipped with a rudder hand control system. E:\FR\FM\10NOP1.SGM 10NOP1 78948 Federal Register / Vol. 81, No. 218 / Thursday, November 10, 2016 / Proposed Rules The subsequent investigation revealed significant cable slack in the rudder control system. This condition, if not detected and corrected, could lead to reduced rudder control, possibly resulting in reduced controllability of the sailplane. To address this potentially unsafe condition, Schleicher issued ASK 21 Technical Note (TN) 38 to provide instructions to amend the ASK 21 Aircraft Flight Manual (AFM), incorporating updated pre-flight inspection instructions to check the rudder control system of sailplanes modified in accordance with the instructions of Schleicher ASK 21 TN 25 (rudder actuated by hand lever for the front pilot seat) or TN 30 (rudder control by hand for the rear pilot seat).

Related Service Information Under 1 CFR Part 51 Alexander Schleicher GmbH & Co. has issued ASK 21 Technical Note No. 38, dated May 31, 2016, The service information describes procedures for inspecting gliders equipped with a rudder hand control system for proper tension and adjustment 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. asabaliauskas on DSK3SPTVN1PROD with PROPOSALS 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 64 products of U.S. registry. We also estimate that it would take about 2 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. VerDate Sep<11>2014 17:02 Nov 09, 2016 Jkt 241001 operators to be $10,880, or $170 per product. In addition, we estimate that any necessary follow-on actions would take about 1 work-hour for cost of $85 per product. We have no way of determining the number of products that may need these actions. the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. 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 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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No.: 2016-0192, dated September 28, 2016 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    A temporary rudder control blockage was reported, involving an 
ASK 21 sailplane equipped with a rudder hand control system.

[[Page 78948]]

The subsequent investigation revealed significant cable slack in the 
rudder control system.
    This condition, if not detected and corrected, could lead to 
reduced rudder control, possibly resulting in reduced 
controllability of the sailplane.
    To address this potentially unsafe condition, Schleicher issued 
ASK 21 Technical Note (TN) 38 to provide instructions to amend the 
ASK 21 Aircraft Flight Manual (AFM), incorporating updated pre-
flight inspection instructions to check the rudder control system of 
sailplanes modified in accordance with the instructions of 
Schleicher ASK 21 TN 25 (rudder actuated by hand lever for the front 
pilot seat) or TN 30 (rudder control by hand for the rear pilot 
seat).
    For reasons described above, this AD requires amendment of the 
applicable Schleicher ASK 21 AFM, revising pre-flight checks of the 
rudder hand control system.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9357.

Related Service Information Under 1 CFR Part 51

    Alexander Schleicher GmbH & Co. has issued ASK 21 Technical Note 
No. 38, dated May 31, 2016, The service information describes 
procedures for inspecting gliders equipped with a rudder hand control 
system for proper tension and adjustment 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 64 products of U.S. 
registry. We also estimate that it would take about 2 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 $10,880, or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 1 work-hour for cost of $85 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 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.

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 adding the following new AD:

Alexander Schleicher GmbH & Co.: Docket No. FAA-2016-9382; 
Directorate Identifier 2016-CE-032-AD.

(a) Comments Due Date

    We must receive comments by December 27, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Alexander Schleicher GmbH & Co. ASK 21 
gliders, all serial numbers, certificated in any category, that are 
modified with a rudder hand control system using either ASK 21 
Technical Note No. 25, dated February 16, 1993, or ASK 21 Technical 
Note No. 30, dated January 22, 2007.

(d) Subject

    Air Transport Association of America (ATA) Code 27: Flight 
Controls.

(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 cable slack in 
gliders equipped with a rudder hand control system. We are issuing 
this proposed AD to correct any excess slack in the rudder hand 
control system, which could result in a short-term blockage of the 
rudder control system causing reduced control.

(f) Actions and Compliance

    Unless already done, do the actions in paragraphs (f)(1) through 
(3) of this AD:
    (1) If the glider is equipped with a rudder actuated by means of 
a hand lever at the left cockpit wall in the front pilot seat by ASK 
21 Technical Note (TN) No. 25, dated February 16, 1993, within the 
next 60 days after the effective date of this AD, replace the flight 
manual (FM) and maintenance manual (MM) pages with the following 
pages in ASK 21 TN No. 38, dated May 31, 2016:
    (i) FM: Check List/1, 16a, 19.1a., and 21.
    (ii) MM: 13, 15.
    (2) If the glider is equipped with a rudder actuated by means of 
a hand lever at the left cockpit wall in the rear pilot seat by ASK 
21 TN No. 30, dated January 22, 2007, within the next 60 days after 
the effective date of this AD, replace the FM and MM pages with the 
following pages in ASK 21 TN No. 38, dated May 31, 2016:
    (i) FM: Check List/1, 16a, 18a, 19b, 19c, 19.1a, and 21.

[[Page 78949]]

    (ii) MM: 13, 15.
    (3) For all affected gliders, within the next 60 days after the 
effective date of this AD and repetitively thereafter at intervals 
not to exceed every 12 months, inspect the rudder cable tension and 
make any necessary corrections following the instructions from FM 
page 19.1a, Checking and Adjusting of the Cable Tension, as 
specified in ASK 21 TN No. 38, dated May 31, 2016.
    (4) For all affected gliders, after the effective date of this 
AD, any glider modified with a rudder hand control system in 
accordance with ASK 21 TN No. 25 or TN No. 30 must also amend the FM 
and MM following the instructions in ASK 21 TN No. 38, dated May 31, 
2016.

(g) Pilot Authorization

    In addition to the provisions of 14 CFR 43.3 and 43.7, the 
actions required by paragraph (f)(1) through (2) of this AD may be 
performed by the owner/operator (pilot) holding at least a private 
pilot certificate and must be entered into the glider records 
showing compliance with this AD following 14 CFR 43.9 (a)(1) through 
(4) and 14 CFR 91.417(a)(2)(v). The record must be maintained as 
required by 14 CFR 91.417, 121.380, or 135.439.

(h) 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 requested using the procedures found in 14 CFR 39.19. Send
