Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by a review showing that inadequate clearance may exist between certain electrical wiring and nearby structures. This proposed AD would require an inspection of certain electrical wiring bundles and feeders, modifications, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by July 27, 2017.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016-0230, dated November 21, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Dassault Aviation Model FALCON 7X airplanes. The MCAI states:

A review of the wiring and tubing lay-out showed that there may be low clearance between electrical wiring and nearby structure. Although no in-service incident has been reported, the minimum clearances could deteriorate over time.

This condition, if not detected and corrected, could lead to interference or contact with structure, provoking an electrical short circuit or fluid leakage, possibly resulting in loss of several functions essential for safe flight.

To initially address this potential unsafe condition, [Dassault Aviation] DA developed some interim modifications (mod) addressing the risk of short circuit and fluid leakage, and EASA issued AD 2010-0029 (later revised) [which corresponds to FAA AD 2011-14-04, Amendment 39-16739 (76 FR 39256, July 6, 2011) (“AD 2011-14-04”)] to require embodiment of those modifications in-service.

Since EASA AD 2010-0029R1 was issued, DA developed another set of modifications, available for in-service application through Service Bulletin (SB) F7X-056, which are considered the final solutions for this unsafe condition.

For the reasons described above, this [EASA] AD requires a one-time [general visual] inspection [for worn or damaged wiring or connectors due to inadequate clearance between wiring and nearby structures] of the affected electrical wiring and, depending on findings, corrective action(s) and modification of the aeroplane.

Corrective actions include modifying the clamping and routing; adding new brackets, clamps, and cable protections; replacing damaged parts; and improving connections using lock wires. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-0532.

Related Rulemaking

AD 2011-14-04 requires inspections for damage to wiring bundles and feeders; and, if necessary, repairs, modifications, and installation of a hydraulic pipe. These actions were considered interim actions to ensure that the minimum required clearance and adequate protection existed among the hydraulic pipe, electrical wiring, and the airplane structure. This proposed AD would require additional inspections and modifications that differ from those in AD 2011-14-04.

This proposed AD would not terminate any action in AD 2011-14-04; rather, both AD actions are necessary to adequately address the unsafe condition.

Related Service Information Under 1 CFR Part 51

We reviewed Dassault Service Bulletin 7X-056, Revision 1, dated July 20, 2016. This service information describes a one-time inspection of certain wiring bundles and feeders, and corrective actions. 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.

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 the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an 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 affects 51 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Inspection and modifications31 work-hours × $85 per hour = $2,635$7,660$10,295$525,045

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD.

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.Start Printed Page 26869

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.

(e) Reason

This AD was prompted by a review that showed that low clearance may exist between certain electrical wiring and nearby structures. We are issuing this AD to detect and correct inadequate clearances between electrical wiring and nearby structures, which could lead to interference or contact with a structure and cause an electrical short circuit or fluid leakage.
