Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking (NPRM).
We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by a report indicating that fuselage panels were manufactured with Start Printed Page 32499defects that could reduce panel fatigue limits. This proposed AD would require a one-time inspection of the affected panels and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016-0250, dated December 15, 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 few pockets of fuselage Section T5 lateral panels were manufactured with defects in certain chemically-milled profiles. The technical investigation concluded that the fatigue limit of the affected panels might be reduced, depending on the defect characteristics.
This condition, if not detected and corrected, could lead to crack propagation, possibly resulting in reduced structural integrity of the fuselage.
To address this potential unsafe condition, DA published Service Bulletin (SB) F7X-042 providing inspection instructions.
For the reasons described above, this [EASA] AD requires a one-time [detailed] inspection of the chemically-milled profiles of the pockets of the Section T5 fuselage lateral panels and, depending on findings, accomplishment of applicable corrective action(s). This [EASA] AD also requires, for some aeroplanes, the installation of a stiffener on the forward pocket.
Applicable corrective actions include repair, if necessary. 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-2017-0694.
Related Service Information Under 1 CFR Part 51
We reviewed Dassault Service Bulletin 7X-042, Revision 1, dated May 3, 2016. This service information describes the inspection of the chemically milled profiles of the pockets of the Section T5 fuselage lateral panels and the installation of a stiffener on the forward pocket on affected airplanes. 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 4 airplanes of U.S. registry.
We estimate the following costs to comply with this proposed AD:
Start Printed Page 32500
|Action||Labor cost||Parts cost||Cost per product||Cost on U.S. operators|
|Panel inspections||Up to 10 work-hours × $85 per hour = $850||$0||Up to $850||Up to $3,400.|
|Stiffener installation (up to 3 airplanes)||2 work-hours × $85 per hour = $170||8,769||$8,939||Up to $26,817.|
According to the manufacturer, all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.
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.
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.
