We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2017– 0074, dated April 28, 2017 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Cracks and deformation have been found on the flap bell crank Part Number (P/N) D60–2757–11–00. Frequent high load conditions have been identified as the root cause. This condition, if not detected and corrected, could lead to failure of the flap bell crank and consequent reduced control of the aeroplane. To address this potential unsafe condition, Diamond Aircraft Industries (DAI) issued Mandatory Service Bulletin (MSB) 42–126/ MSB 42NG–066 and the corresponding Work Instruction (WI) MSB 42–126/WI–MSB 42NG–066 (single document), hereafter referred to as ‘the applicable MSB’ in this [EASA] AD, providing inspection and modification instructions. For the reason described above, this [EASA] AD requires modification of the flap control system by installing two spacers to replace a single long spacer, repetitive inspections of the flap bell crank, and, depending on findings, replacement of the flap bell crank with an improved part. Installation of an improved flap bell crank constitutes terminating action for the repetitive inspections required by this [EASA] AD. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2017–0638. Related Service Information Under 1 CFR Part 51 Diamond Aircraft Industries GmbH has issued Mandatory Service Bulletin MSB 42–126 MSB/42NG–066, dated March 27, 2017 (single document), and Work Instruction WI–MSB 42–126/WI– MSB 42NG–066, dated March 27, 2017 (single document). In combination, this service information describes procedures for repetitively inspecting the flap bell crank for cracks, replacing the flap bell crank if cracks are found, and modification of the flap control system. 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 00007 Fmt 4702 Sfmt 4702 28595 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 will affect 190 products of U.S. registry. We also estimate that it would take about 4 work-hours per product to comply with the initial inspection requirement of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the initial inspection requirement of this proposed AD on U.S. operators to be $64,000, or $340 per product. We also estimate that it would take about 2 work-hours per product to comply with the repetitive inspection requirement of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the repetitive inspection requirement of this proposed AD on U.S. operators to be $32,300, or $170 per product. In addition, we estimate that any necessary replacement action would take about 1 work-hour and require parts costing $430, for a cost of $515 per product. We have no way of determining the number of products that may need these actions. According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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: E:\FR\FM\23JNP1.SGM 23JNP1 28596 Federal Register / Vol. 82, No. 120 / Friday, June 23, 2017 / Proposed Rules 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. 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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2017-0074, dated April 28, 2017 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    Cracks and deformation have been found on the flap bell crank 
Part Number (P/N) D60-2757-11-00. Frequent high load conditions have 
been identified as the root cause.
    This condition, if not detected and corrected, could lead to 
failure of the flap bell crank and consequent reduced control of the 
aeroplane.
    To address this potential unsafe condition, Diamond Aircraft 
Industries (DAI) issued Mandatory Service Bulletin (MSB) 42-126/MSB 
42NG-066 and the corresponding Work Instruction (WI) MSB 42-126/WI-
MSB 42NG-066 (single document), hereafter referred to as `the 
applicable MSB' in this [EASA] AD, providing inspection and 
modification instructions.
    For the reason described above, this [EASA] AD requires 
modification of the flap control system by installing two spacers to 
replace a single long spacer, repetitive inspections of the flap 
bell crank, and, depending on findings, replacement of the flap bell 
crank with an improved part. Installation of an improved flap bell 
crank constitutes terminating action for the repetitive inspections 
required by this [EASA] AD.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0638.

Bulletin MSB 42-126 MSB/42NG-066, dated March 27, 2017 (single 
document), and Work Instruction WI-MSB 42-126/WI-MSB 42NG-066, dated 
March 27, 2017 (single document). In combination, this service 
information describes procedures for repetitively inspecting the flap 
bell crank for cracks, replacing the flap bell crank if cracks are 
found, and modification of the flap control system. 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 will affect 190 products of U.S. 
registry. We also estimate that it would take about 4 work-hours per 
product to comply with the initial inspection requirement of this 
proposed AD. The average labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of the initial 
inspection requirement of this proposed AD on U.S. operators to be 
$64,000, or $340 per product.
    We also estimate that it would take about 2 work-hours per product 
to comply with the repetitive inspection requirement of this proposed 
AD. The average labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of the repetitive 
inspection requirement of this proposed AD on U.S. operators to be 
$32,300, or $170 per product.
    In addition, we estimate that any necessary replacement action 
would take about 1 work-hour and require parts costing $430, for a cost 
of $515 per product. We have no way of determining the number of 
products that may need these actions.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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:

[[Page 28596]]

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.

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 adding the following new AD:

Diamond Aircraft Industries GmbH: Docket No. FAA-2017-0638; 
Directorate Identifier 2017-CE-018-AD.

(a) Comments Due Date

    We must receive comments by August 7, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Diamond Aircraft Industries GmbH Model DA 42, 
DA 42 M-NG, and DA 42 NG airplanes, serial numbers 42.004 through 
42.427, 42.AC001 through 42.AC151, 42.M001 through 42.M026, 42.N001 
through 42.N067, 42.N100 through 42.N129, 42.NC001 through 42.NC008, 
and 42.MN001 through 42.MN033, certificated in any category.

(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 crack formation 
on the flap bell crank. We are issuing this AD to prevent failure of 
the flap bell crank, which could result in reduced control.

(f) Actions and Compliance

    Unless already done, do the following actions:
    (1) Inspect the flap bell crank, part number (P/N) D60-2757-11-
00, and modify the flap control system by installing two spacers, P/
N DS BU2-10-06-0065-C, where the flap actuator rod end bearing is 
connected to the flap bell crank, following the Instructions section 
in Diamond Aircraft Industries GmbH (DAI) Work Instruction WI-MSB 
42-126/WI-MSB 42NG-066, dated March 27, 2017 (single document), as 
specified in DAI Mandatory Service Bulletin MSB 42-126/MSB 42NG-066, 
dated March 27, 2017 (single document), at whichever of the 
following compliance times occurs later:
    (i) Before exceeding 600 hours time-in-service (TIS), and 
repetitively thereafter at intervals not to exceed 200 hours TIS.
    (ii) Within the next 100 hours TIS after the effective date of 
this AD or within the next 6 months after the effective date of this 
AD, whichever occurs first, and repetitively thereafter at intervals 
not to exceed 200 hours TIS.
    (2) If any discrepancies are found during any inspection 
required in paragraph (f)(1) of this AD, before further flight, 
replace the flap bell crank with an improved part, P/N D60-2757-11-
00_01, following the Instructions section in DAI Work Instruction 
WI-MSB 42-126/WI-MSB 42NG-066, dated March 27, 2017 (single 
document), as specified in DAI Mandatory Service Bulletin MSB 42-
126/MSB 42NG-066, dated March 27, 2017 (single document). Installing 
P/N D60-2757-11-00_01 terminates the repetitive inspections required 
in paragraph (f)(1) of this AD. This installation as terminating 
action may be done in lieu of the inspections required in paragraph 
(f)(1) of this AD.

(g) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
