Airworthiness Directives; DG Flugzeugbau GmbH

SUMMARY

We propose to adopt a new airworthiness directive (AD) 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 Kleinmotoren GmbH Service Bulletin (SB)/Technische Mitteilung (TM) 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 the potential of an in-flight shut-down and engine fire due to failure of the connecting stud for the two fuel injector mounts of the engine redundancy system on gliders equipped with a Solo 2625 02i engine. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

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.: 2014-0269, dated December 11, 2014 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:

Page 9536

An occurrence was reported involving a failure of the connecting stud for the two fuel injector mounts of the engine redundancy system.

This condition, if not corrected, could lead to an uncommanded in-flight engine shut-down and engine fire, possibly resulting in loss of control of the aeroplane.

To address this unsafe condition, Solo Kleinmotoren GmbH issued SB/TM 4600-5 to provide instructions for reinforcement and securing of the injector mounts.

For the reason described above, this AD requires modification of the engine redundancy system.

Solo Kleinmotoren GmbH SB/TM 4600-3 (currently at issue 2, dated 03 December 2012) will be revised to incorporate the modification required by SB/TM 4600-5 for future Solo 2625 02i engines.

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

0051.

Related Service Information Under 1 CFR Part 51

Solo Kleinmotoren GmbH has issued Technische Mitteilung (English translation: Service Bulletin), Nr. 4600-5, Ausgabe 2 (English translation: Issue 2), dated December 12, 2014. The service information describes procedures for changing the fuel injector mounts of the engine redundancy system and securing the connection of the lower to the upper mount. 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 3 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $67 per product.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $456, or $152 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.

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
