Airworthiness Directives; GROB-WERKE 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 GROB-WERKE GMBH & CO KG Model G 115E airplanes. 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 incorrect cable routing causing electrical shorting behind the left-hand (LH) cockpit instrument panel. 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 AD No.: 2013-0017, dated January 17, 2013 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:
Occurrences were reported of finding an electrical shorting of main cable loom behind the left-hand (LH) instrument panel of some Grob G115E aeroplanes. In one case, the main cable loom arcing caused an Electronic Horizontal Situation Indicator failure. During the fleet checks, additional cases of main cable loom routing and consequent rubbing with Omni Bearing Selector behind the cockpit instrument panel were identified, while the cable routing was not in conformity with the approved type design.
The investigation results concluded that the instrument panels of affected aeroplanes were removed and subsequently re-installed, in service, during embodiment of various optional modifications.
This condition, if not detected and corrected, could lead to smoke in the cockpit and/or functional loss of navigation equipment and instruments.
To address this potential unsafe condition, Grob Aircraft AG published Mandatory Service Bulletin (MSB) MSB1078-191/1, providing instructions to inspect and correct the cable routing behind the cockpit instrument panel.
For the reason described above, this AD requires accomplishment of a one- time inspection to verify correct cable routing behind the LH cockpit instrument panel and, depending on findings, correction and replacement of damaged parts.
You may obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
GROB-WERKE has issued Service Bulletin No. MSB1078-191/1, dated January 15, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.
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 0 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 $10 per product.
Page 21083
Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $0 per product.
In addition, we estimate that any necessary follow-on actions would take about 8 work-hours and require parts costing $100, for a cost of $780 per product. We have no way of determining the number of products that may need these actions.
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.
