VerDate Sep<11>2014 13:51 Mar 01, 2017 Jkt 241001 Discussion On May 22, 2003, we issued AD 2003–11–12, Amendment 39–13171 (68 FR 32629, June 2, 2003) (‘‘AD 2003–11– 12’’). That AD required actions intended to address an unsafe condition on ZLIN AIRCRAFT a.s. Model Z–242L airplanes and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. Since we issued AD 2003–11–12, a revision to the airworthiness limitations chapter of the aircraft maintenance manual has been issued, and the State of Design airworthiness authority took AD action, as identified below. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2017– 0005, dated January 10, 2017 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: The airworthiness limitations for the Zlin Aircraft a.s. Z 242 L aeroplanes, which are approved by EASA, are defined and published in Chapter 9 of Zlin Aircraft a.s. Z 242 L Maintenance Manual (MM)—Volume I Document 003.021.1 (in Czech language) or in Chapter 9 of Z 242 L MM—Volume I Document 003.22.1 (in English language). These instructions have been identified as mandatory for continued airworthiness. Failure to accomplish these instructions could result in an unsafe condition. Zlin Aircraft a.s. recently published Revision 22 to Chapter 9, Volume I, of the Z 242 L MM, introducing new and/or more restrictive limitations. For the reason described above, this AD requires accomplishment of the actions specified in the Zlin Aircraft a.s. Z 242 L MM Chapter 9, Volume I, at Revision 22. You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2017–0156. Related Service Information Under 1 CFR Part 51 ZLIN AIRCRAFT a.s. has issued Z 242 L DOC. No. 003.22.1 Maintenance Manual—Vol. I. Chapter 9, Airworthiness Limitations, Revision No. 22, dated March 15, 2016. The revision to the Limitations sections introduces new and/or more restrictive safe life limits for the Model Z 242 airplane. 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. PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 FAA’s Determination and Requirements of This 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 would affect 30 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the proposed requirement to incorporate the new revision into the Limitations section of the FAAapproved maintenance program (e.g., maintenance manual). The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this portion of this proposed AD on U.S. operators to be $2,550, or $85 per product. The above costs only account for the time to incorporate the document into the Limitations section of the FAAapproved maintenance program. These proposed limitations would impose more restrictive life limits on some parts and provide new life limits for others. While the cost of these proposed replacements could be expensive, they would only be required to operate the airplane past the established times. Ultimately, the proposed estimated cost of replacing all life-limited parts could come close to the cost of the airplane. These proposed life limits are necessary to continue to operate the airplane in an airworthy manner. 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 E:\FR\FM\02MRP1.SGM 02MRP1 Federal Register / Vol. 82, No. 40 / Thursday, March 2, 2017 / Proposed Rules 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. 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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Amendment 39–13171 (68 FR 32629, June 2, 2003), and adding the following new AD: pmangrum on DSK3GDR082PROD with PROPOSALS ■ ZLIN AIRCRAFT a.s.

Discussion On May 8, 2015, we issued AD 2015– 08–51, Amendment 39–18160 (80 FR 28172, May 18, 2015), which was sent previously as an emergency AD to all known U.S. owners and operators of Enstrom Model F–28A, 280, F–28C, F– 28C–2, F–28C–2R, 280C, F–28F, F–28F– R, 280F, 280FX, and 480 helicopters. AD 2015–08–51 applies to helicopters with a spindle part number (P/N) 28– 14282–11 or 28–14282–13 installed and requires conducting a one-time magnetic particle inspection (MPI) of the spindle for cracks and reporting the inspection results to the FAA. AD 2015– 08–51 was prompted by a fatal accident and reports of spindles with cracks. The actions of AD 2015–08–51 are intended to detect a crack in a spindle and prevent loss of a main rotor blade and subsequent loss of control of the helicopter. Actions Since AD 2015–08–51 Was Issued Since we issued AD 2015–08–51, we received additional reports of cracked spindles. Additionally, Enstrom revised its service information to reduce the time for the initial MPI from 3,500 hours TIS to 1,500 hours TIS and extend the compliance time for a recurring MPI of the spindles from 300 hours TIS to 500 hours TIS. Based on a review of the inservice data and a fatigue analysis, the FAA determined a life limit and repetitive MPIs were necessary to reduce the risk of a crack developing in a spindle. We also determined the reporting requirement in AD 2015–08– 51 is no longer necessary. We issued AD 2015–08–51 as interim action; this proposed AD would provide long-term requirements to prevent a spindle failure. Accordingly, this E:\FR\FM\02MRP1.SGM 02MRP1

Airworthiness Directives; ZLIN AIRCRAFT a.s. Airplanes

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 
ZLIN AIRCRAFT a.s. Model Z-242L airplanes that would supersede AD 2003-
11-12. 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 a need to 
incorporate new revisions into the Limitations section, Chapter 9, of 
the FAA-approved maintenance program (e.g., maintenance manual) to 
impose new or more restrictive life limits on critical components. 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 17, 2017.

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

Discussion

    On May 22, 2003, we issued AD 2003-11-12, Amendment 39-13171 (68 FR 
32629, June 2, 2003) (``AD 2003-11-12''). That AD required actions 
intended to address an unsafe condition on ZLIN AIRCRAFT a.s. Model Z-
242L airplanes and was based on mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country.
    Since we issued AD 2003-11-12, a revision to the airworthiness 
limitations chapter of the aircraft maintenance manual has been issued, 
and the State of Design airworthiness authority took AD action, as 
identified below.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2017-0005, dated January 10, 2017 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    The airworthiness limitations for the Zlin Aircraft a.s. Z 242 L 
aeroplanes, which are approved by EASA, are defined and published in 
Chapter 9 of Zlin Aircraft a.s. Z 242 L Maintenance Manual (MM)--
Volume I Document 003.021.1 (in Czech language) or in Chapter 9 of Z 
242 L MM--Volume I Document 003.22.1 (in English language). These 
instructions have been identified as mandatory for continued 
airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    Zlin Aircraft a.s. recently published Revision 22 to Chapter 9, 
Volume I, of the Z 242 L MM, introducing new and/or more restrictive 
limitations.
    For the reason described above, this AD requires accomplishment 
of the actions specified in the Zlin Aircraft a.s. Z 242 L MM 
Chapter 9, Volume I, at Revision 22.

You may examine the MCAI on the Internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2017-0156.

Related Service Information Under 1 CFR Part 51

    ZLIN AIRCRAFT a.s. has issued Z 242 L DOC. No. 003.22.1 Maintenance 
Manual--Vol. I. Chapter 9, Airworthiness Limitations, Revision No. 22, 
dated March 15, 2016. The revision to the Limitations sections 
introduces new and/or more restrictive safe life limits for the Model Z 
242 airplane. 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 This 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 would affect 30 products of U.S. 
registry. We also estimate that it would take about 1 work-hour per 
product to comply with the proposed requirement to incorporate the new 
revision into the Limitations section of the FAA-approved maintenance 
program (e.g., maintenance manual). The average labor rate is $85 per 
work-hour.
    Based on these figures, we estimate the cost of this portion of 
this proposed AD on U.S. operators to be $2,550, or $85 per product.
    The above costs only account for the time to incorporate the 
document into the Limitations section of the FAA-approved maintenance 
program. These proposed limitations would impose more restrictive life 
limits on some parts and provide new life limits for others. While the 
cost of these proposed replacements could be expensive, they would only 
be required to operate the airplane past the established times. 
Ultimately, the proposed estimated cost of replacing all life-limited 
parts could come close to the cost of the airplane. These proposed life 
limits are necessary to continue to operate the airplane in an 
airworthy manner.

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

[[Page 12307]]

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 removing Amendment 39-13171 (68 FR 
32629, June 2, 2003), and adding the following new AD:

ZLIN AIRCRAFT a.s. (type certificate previously held by MORAVAN 
a.s.): Docket No. FAA-2017-0156; Directorate Identifier 2017-CE-003-
AD.

(a) Comments Due Date

    We must receive comments by April 17, 2017.

(b) Affected ADs

    This AD replaces AD 2003-11-12, Amendment 39-13171 (68 FR 32629, 
June 2, 2003) (``AD 2003-11-12'')

(c) Applicability

    This AD applies to ZLIN AIRCRAFT a.s. Model Z-242L airplanes, 
all serial numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 5: Time Limits.

(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 a need to 
incorporate new revisions into the Limitations section, Chapter 9, 
of the FAA-approved maintenance program (e.g., maintenance manual). 
We are issuing this AD to prevent structural failure of the wing due 
to fatigue cracking. Such failure could result in a wing separating 
from the airplane with consequent loss of control.

(f) Actions and Compliance

    Unless already done, do the following actions:
    (1) For all affected airplanes: As of March 21, 2003 (the 
effective date of AD 2003-03-13 (68 FR 4905, January 21, 2003)), 
annotate Acrobatic and Utility category operational time in the 
logbook. If the airplane is utilized in either of these categories 
at any time during a flight, annotate the total time for that flight 
in the Utility or Acrobatic category, as appropriate. Do the logbook 
annotation following the procedures in Moravan Mandatory Service 
Bulletin Z 242L/37a (Z 142C/17a), Rev. 1, dated October 31, 2000; 
and Moravan Mandatory Service Bulletin Z 242L/38a (Z142C/18a)--Rev. 
1, April 15, 2003. The owner/operator holding at least a private 
pilot certificate as authorized by section 43.7 may do this action.
    (2) For airplane serial numbers 0001 through 0656 that do not 
have strengthened wings installed (both left and right side) in 
accordance with Moravan Mandatory Service Bulletin Z 242L/27a--Rev 
2. dated April 15, 2003, or Rev. 1, dated October 31, 2000:
    (i) On or before 10 days after June 5, 2003 (the effective date 
of AD 2003-11-12), incorporate aerobatic frequency information into 
the Limitations section of the airplane flight manual (AFM) as 
specified in Moravan Mandatory Service Bulletin Z 242L/38a--Rev. 1, 
dated April 15, 2003. The owner/operator holding at least a private 
pilot certificate as authorized by section 43.7 may do this action. 
Make an entry into the aircraft records showing compliance with 
these portions of the AD in accordance with section 43.9 of the 
Federal Aviation Regulations (14 CFR 43.9).
    (ii) On or before reaching 190 hours time-in-service in the 
Acrobatic category and/or Utility category or on or before 90 days 
after March 21, 2003 (the effective date of AD 2003-03-13 (68 FR 
4905, January 21, 2003)), whichever occurs later, insert the 
following information into the Limitations section of the airplane 
flight manual (AFM): ``Do not operate in the Acrobatic or Utility 
category. Operate in the Normal category only.''
    The owner/operator holding at least a private pilot certificate 
as authorized by section 43.7 of the Federal Aviation Regulations 
(14 CFR 43.7) may accomplish this AFM insertion of this AD. Make an 
entry into the aircraft records showing compliance with these 
portions of the AD in accordance with section 43.9 of the Federal 
Aviation Regulations (14 CFR 43.9). This operational restriction is 
referenced in Moravan Mandatory Service Bulletin Z 242L/37a (Z 142C/
17a), Rev. 1, dated October 31, 2000.
    (3) For airplane serial numbers 0657 or higher or one in the 
range of 0001 through 0656 that has strengthened wings (both left 
and right side) installed in accordance with Moravan Mandatory 
Service Bulletin Z 242L/27a--Rev. 1, dated October 31, 2000, or Rev. 
2, dated April 15, 2003: On or before 10 days after June 5, 2003 
(the effective date of AD 2003-11-12), incorporate aerobatic 
frequency information into the Limitations section of the airplane 
flight manual (AFM) as specified in Moravan Mandatory Service 
Bulletin Z 242L/38a--Rev. 1, dated April 15, 2003. The owner/
operator holding at least a private pilot certificate as authorized 
by section 43.7 may do this action. Make an entry into the aircraft 
records showing compliance with these portions of the AD in 
accordance with section 43.9 of the Federal Aviation Regulations (14 
CFR 43.9).
    (4) For all affected airplanes: Within 10 days after the 
effective date of this AD, insert Chapter 9, Airworthiness 
Limitations, Revision No. 22, dated March 15, 2016, of ZLIN AIRCRAFT 
a.s. Z 242 L, Doc, No. 003.002.1 Maintenance Manual--Vol. I into the 
Limitations section of the FAA-approved maintenance program (e.g., 
maintenance manual). The owner/operator holding at least a private 
pilot certificate as authorized by section 43.7 of the Federal 
Aviation Regulations (14 CFR 43.7) may accomplish this maintenance 
manual insertion requirement of this AD. Make an entry into the 
aircraft records showing compliance with these portions of the AD in 
accordance with section 43.9 of the Federal Aviation Regulations (14 
CFR 43.9). If a discrepancy is found during the accomplishment of 
any of the actions required by the document listed in this 
paragraph, before further flight after finding such discrepancy, 
contact ZLIN AIRCRAFT a.s. at the address specified in paragraph (h) 
of this AD for an FAA-approved repair scheme and incorporate that 
repair scheme.
