We will post all comments we receive, without change, to https:// 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 We issued AD 2017–11–03, Amendment 39–18902 (82 FR 24015; May 25, 2017) (‘‘AD 2017–11–03’’). That AD required actions intended to address an unsafe condition on DG Flugzeugbau GmbH Model DG–500MB gliders and was based on mandatory continuing PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 airworthiness information (MCAI) originated by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. That MCAI is EASA AD No.: 2016–0254, dated December 15, 2016, correction dated January 4, 2017 (referred to after this as ‘‘the MCAI’’). Since we issued AD 2017–11–03, the FAA has now type certificated the DG Flugzeugbau GmbH Model DG–1000M glider and that glider model is equipped with a Solo 2625 02i engine. Since this model has the same engine, it is subject to the same unsafe condition in AD 2017–11–03. You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2018–0093. Related Service Information Under 1 CFR Part 51 Solo Kleinmotoren GmbH has issued Technische Mitteilung (English translation: Service Bulletin) Nr. 4600– 6, Ausgabe 1 (English translation: Issue 1), dated November 16, 2016, approved for incorporation by reference on June 29, 2017 (82 FR 24015; May 25, 2017). The service information describes procedures for a software update that provides new settings to the engine control unit (ECU) to lower the load on the bearings of the crankshaft. 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 6 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. E:\FR\FM\12FEP1.SGM 12FEP1 Federal Register / Vol. 83, No. 29 / Monday, February 12, 2018 / Proposed Rules under the criteria of the Regulatory Flexibility Act. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $1,020, or $170 per product. daltland on DSKBBV9HB2PROD with PROPOSALS 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes, gliders, balloons, airships, domestic business jet transport airplanes, and associated appliances to the Director of the Policy and Innovation Division. 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 VerDate Sep<11>2014 17:29 Feb 09, 2018 Jkt 244001 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 39–18902 (82 FR 24015; May 25, 2017), and adding the following new AD: ■ DG Flugzeugbau GmbH: Docket No. FAA– 2018–0093; Product Identifier 2017–CE– 047–AD. (a) Comments Due Date We must receive comments by March 29, 2018. (b) Affected ADs This AD replaces AD 2017–11–03, Amendment 39–18902 (82 FR 24015; May 25, 2017) (‘‘AD 2017–11–03’’). (c) Applicability This AD applies to DG Flugzeugbau GmbH DG–500MB and DG–1000M gliders, all serial numbers, certificated in any category, that are equipped with Solo 2625 02 engines modified with a fuel injection system following the instructions of Solo Kleinmotoren GmbH Service Bulletin (SB)/ Technische Mitteilung (TM) 4600–3 ‘‘Fuel Injection System’’ and re-identified as Solo 2625 02i, or equipped with a Solo 2625 02i engine at manufacture, and have engine serial numbers (S/N) through 369/207, except engine S/N’s 354/194, 356/196, 357/197, 358/ 198, 361/201, 362/202, 363/203, 364/204, and 368/206. (d) Subject Air Transport Association of America (ATA) Code 73: Engine fuel and control. (e) Reason 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. AD 2017– 11–03 resulted from failure of the connecting rod bearing because of too much load on the rod bearings from the engine control unit. This AD results from the need to add an airplane model to the applicability. We are issuing this AD to prevent such failure that could lead to the potential of an in-flight shut-down and engine fire and result in loss PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 5957 of control and to include FAA type certificated DG Flugzeugbau GmbH Model DG–1000M gliders with Solo 2625 02i engines. (f) Actions and Compliance (1) For DG Flugzeugbau GmbH Model DG– 500MB gliders: Unless already done, within the next 60 days after June 29, 2017 (the effective date of AD 2017–11–03), modify the engine by installing a software update for the engine control unit (ECU) following the actions in Solo Kleinmotoren GmbH Technische Mitteilung (English translation: Service Bulletin), Nr. 4600–6, Ausgabe 1 (English translation: Issue 1), dated November 16, 2016. (2) For DG Flugzeugbau GmbH Model DG– 1000M gliders: Unless already done, within the next 60 days after the effective date of this AD, modify the engine by installing a software update for the engine control unit (ECU) following the actions in Solo Kleinmotoren GmbH Technische Mitteilung (English translation: Service Bulletin), Nr. 4600–6, Ausgabe 1 (English translation: Issue 1), dated November 16, 2016. (3) For all gliders: After the modification of an engine as required by paragraph (f)(1) or (f)(2) of this AD, do not install a replacement ECU on that engine and do not upload any software update to the ECU of that engine unless the ECU software version is as specified in Solo Kleinmotoren GmbH Technische Mitteilung (English translation: Service Bulletin), Nr. 4600–6, Ausgabe 1 (English translation: Issue 1), dated November 16, 2016. (4) For all gliders: The Note in Solo Kleinmotoren GmbH Technische Mitteilung (English translation: Service Bulletin), Nr. 4600–6, Ausgabe 1 (English translation: Issue 1), dated November 16, 2016, stating ‘‘the actions have to be accomplished by a certified maintenance organization and must be released to service accordingly’’ is not applicable to this AD. Note 1 to paragraph (f) of this AD: This service information contains German to English translation. The EASA used the English translation in referencing the document. For enforceability purposes, we will refer to the Solo Kleinmotoren service information as it appears on the document. (g) 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.

Discussion We issued AD 2015–24–06, Amendment 39–18338 (80 FR 75788, December 4, 2015) (‘‘AD 2015–24–06’’), for certain Gulfstream Aerospace Corporation (Gulfstream) Model GVI airplanes. AD 2015–24–06 requires repetitive breakaway torque checks and torqueing of the MLG brake inlet selfsealing couplings. AD 2015–24–06 also requires inserting a dispatch and takeoff limitation to the Limitations section of the airplane flight manual to include procedures to follow if certain display indications occur. AD 2015–24–06 resulted from reports of the self-sealing couplings on the MLG brake inlet fitting backing out of the fully seated position. This unsafe condition could lead to loss of hydraulic pressure to the affected brake. We issued AD 2015–24–06 to detect and correct inadequate torque on the self-sealing couplings and prevent loss of braking capability on one or multiple brakes, which could lead to runway overrun or asymmetrical braking that could result in lateral runway excursion. Actions Since AD 2015–24–06 Was Issued Since we issued AD 2015–24–06, a modification for the MLG and brake assembly has been developed that eliminates the self-sealing coupling and uses a permanent hose design. This modification when incorporated would terminate the need for the repetitive breakaway torque checks and torqueing of the brake inlet self-sealing couplings. Related Service Information Under 1 CFR Part 51 We reviewed Gulfstream G650 Customer Bulletin Number 155B, dated July 26, 2017; and Gulfstream G650ER Customer Bulletin Number 155B, dated July 26, 2017. For the applicable model designations, this service information describes procedures to modify the MLG and brake assemblies.

Airworthiness Directives; DG Flugzeugbau GmbH Gliders

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2017-11-
03 for DG Flugzeugbau GmbH Model DG-500MB gliders that are equipped 
with a Solo 2625 02 engine modified with a fuel injection system 
following the instructions of Solo Kleinmoteren GmbH Technische 
Mitteilung (TM)/Service Bulletin (SB) 4600-3 ``Fuel Injection System'' 
and identified as Solo 2625 02i. 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 failure of the connecting rod bearing resulting from too 
much load on the rod bearings from the engine control unit. This 
proposed AD adds DG Flugzeugbau GmbH Model DG-1000M gliders equipped 
with Solo 2625 02i engines to the applicability. We are issuing this 
proposed AD to require actions to address the unsafe condition on these 
products.

Discussion

    We issued AD 2017-11-03, Amendment 39-18902 (82 FR 24015; May 25, 
2017) (``AD 2017-11-03''). That AD required actions intended to address 
an unsafe condition on DG Flugzeugbau GmbH Model DG-500MB gliders and 
was based on mandatory continuing airworthiness information (MCAI) 
originated by the European Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Community. That 
MCAI is EASA AD No.: 2016-0254, dated December 15, 2016, correction 
dated January 4, 2017 (referred to after this as ``the MCAI'').
    Since we issued AD 2017-11-03, the FAA has now type certificated 
the DG Flugzeugbau GmbH Model DG-1000M glider and that glider model is 
equipped with a Solo 2625 02i engine. Since this model has the same 
engine, it is subject to the same unsafe condition in AD 2017-11-03.
    You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0093.

Related Service Information Under 1 CFR Part 51

    Solo Kleinmotoren GmbH has issued Technische Mitteilung (English 
translation: Service Bulletin) Nr. 4600-6, Ausgabe 1 (English 
translation: Issue 1), dated November 16, 2016, approved for 
incorporation by reference on June 29, 2017 (82 FR 24015; May 25, 
2017). The service information describes procedures for a software 
update that provides new settings to the engine control unit (ECU) to 
lower the load on the bearings of the crankshaft. 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 6 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.

[[Page 5957]]

    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $1,020, or $170 per product.

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to small airplanes, gliders, 
balloons, airships, domestic business jet transport airplanes, and 
associated appliances to the Director of the Policy and Innovation 
Division.

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

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 39-18902 (82 FR 
24015; May 25, 2017), and adding the following new AD:

DG Flugzeugbau GmbH: Docket No. FAA-2018-0093; Product Identifier 
2017-CE-047-AD.

(a) Comments Due Date

    We must receive comments by March 29, 2018.

(b) Affected ADs

    This AD replaces AD 2017-11-03, Amendment 39-18902 (82 FR 24015; 
May 25, 2017) (``AD 2017-11-03'').

(c) Applicability

    This AD applies to DG Flugzeugbau GmbH DG-500MB and DG-1000M 
gliders, all serial numbers, certificated in any category, that are 
equipped with Solo 2625 02 engines modified with a fuel injection 
system following the instructions of Solo Kleinmotoren GmbH Service 
Bulletin (SB)/Technische Mitteilung (TM) 4600-3 ``Fuel Injection 
System'' and re-identified as Solo 2625 02i, or equipped with a Solo 
2625 02i engine at manufacture, and have engine serial numbers (S/N) 
through 369/207, except engine S/N's 354/194, 356/196, 357/197, 358/
198, 361/201, 362/202, 363/203, 364/204, and 368/206.

(d) Subject

    Air Transport Association of America (ATA) Code 73: Engine fuel 
and control.

(e) Reason

    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. AD 2017-11-03 resulted from failure of the connecting rod 
bearing because of too much load on the rod bearings from the engine 
control unit. This AD results from the need to add an airplane model 
to the applicability. We are issuing this AD to prevent such failure 
that could lead to the potential of an in-flight shut-down and 
engine fire and result in loss of control and to include FAA type 
certificated DG Flugzeugbau GmbH Model DG-1000M gliders with Solo 
2625 02i engines.

(f) Actions and Compliance

    (1) For DG Flugzeugbau GmbH Model DG-500MB gliders: Unless 
already done, within the next 60 days after June 29, 2017 (the 
effective date of AD 2017-11-03), modify the engine by installing a 
software update for the engine control unit (ECU) following the 
actions in Solo Kleinmotoren GmbH Technische Mitteilung (English 
translation: Service Bulletin), Nr. 4600-6, Ausgabe 1 (English 
translation: Issue 1), dated November 16, 2016.
    (2) For DG Flugzeugbau GmbH Model DG-1000M gliders: Unless 
already done, within the next 60 days after the effective date of 
this AD, modify the engine by installing a software update for the 
engine control unit (ECU) following the actions in Solo Kleinmotoren 
GmbH Technische Mitteilung (English translation: Service Bulletin), 
Nr. 4600-6, Ausgabe 1 (English translation: Issue 1), dated November 
16, 2016.
    (3) For all gliders: After the modification of an engine as 
required by paragraph (f)(1) or (f)(2) of this AD, do not install a 
replacement ECU on that engine and do not upload any software update 
to the ECU of that engine unless the ECU software version is as 
specified in Solo Kleinmotoren GmbH Technische Mitteilung (English 
translation: Service Bulletin), Nr. 4600-6, Ausgabe 1 (English 
translation: Issue 1), dated November 16, 2016.
    (4) For all gliders: The Note in Solo Kleinmotoren GmbH 
Technische Mitteilung (English translation: Service Bulletin), Nr. 
4600-6, Ausgabe 1 (English translation: Issue 1), dated November 16, 
2016, stating ``the actions have to be accomplished by a certified 
maintenance organization and must be released to service 
accordingly'' is not applicable to this AD.
    Note 1 to paragraph (f) of this AD: This service information 
contains German to English translation. The EASA used the English 
translation in referencing the document. For enforceability 
purposes, we will refer to the Solo Kleinmotoren service information 
as it appears on the document.
