Airworthiness Directives; DG Flugzeugbau GmbH Gliders

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

ACTION: Final rule.

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

SUMMARY: We are superseding 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 4600-3 and identified as Solo 2625 02i. 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 failure of the connecting rod bearing resulting from too much load on the rod bearings from the engine control unit. This AD adds a model to the applicability. We are issuing this AD to require actions to address the unsafe condition on these products.

DATES: This AD is effective June 26, 2018.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of June 29, 2017 (82 FR 24015; May 25, 2017).

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 DG Flugzeugbau GmbH Models DG-500MB and DG-1000M gliders. That NPRM was published in the Federal Register on February 12, 2018 (83 FR 5956), and proposed to supersede AD 2017-11-03, Amendment 39-18902 (82 FR 24015; May 25, 2017) (``AD 2017-11-03''). 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.

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. You may examine the MCAI on the internet at: https://www.regulations.gov/document?D=FAA-2017-0158-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM 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:

Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and

Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

We reviewed Solo Kleinmotoren GmbH 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 AD.

Costs of Compliance

We estimate that this 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 AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of this 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

Page 23576

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 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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by 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 39-18902 (82 FR 24015; May 25, 2017) and adding the following new AD:

    2018-10-09 DG Flugzeugbau GmbH: Amendment 39-19284; Docket No. FAA-

    2018-0093; Product Identifier 2017-CE-047-AD.

    (a) Effective Date

    This airworthiness directive (AD) becomes effective June 26, 2018.

    (b) Affected ADs

    This AD supersedes 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 Models DG-500MB and DG-

    1000M gliders, all serial numbers, certificated in any category, that are:

    (1) Equipped with Solo 2625 02 engine 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

    (2) equipped with a Solo 2625 02i engine at manufacture and have engine serial numbers S/Ns up to 369/207, except engine S/Ns 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. 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 AD results from the need to add a glider 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.

    (f) Actions and Compliance

    (1) Unless already done, 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, at the applicable compliance time in paragraph (f)(1)(i) or (ii) of this AD.

    (i) For Model DG-500MB gliders, within the next 60 days after June 29, 2017 (the effective date of AD 2017-11-03); or

    (ii) For Model DG-1000M gliders, within the next 60 days after the effective date of this AD.

    (2) After the modification of an engine as required by paragraph (f)(1)(i) or (f)(1)(ii) 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.

    (3) 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, Small Airplane Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Jim Rutherford, Aerospace Engineer, FAA, Small Airplane Standards Branch, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4165; fax: (816) 329-
