Amendment of Restricted AreasR-2901A, B, G, H, J, K, L and N; Avon Park, FL
This action makes minor adjustments to the latitude/longitude positions of two points in the descriptions of restricted areas R- 2901A, B, G, H, J, K, L and N at the Avon Park Air Force Range, FL. The corrections are the result of more accurate digital plotting of the points.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This proposed AD was prompted by a report of an aft equipment bay fire due to chafing and subsequent arcing of the integrated drive generator (IDG) power cables. Additionally, we have received several reports of broken support brackets of the hydraulic lines. This proposed AD would require a one-time inspection of the IDG power cables for chafing, and for any cracked or broken support bracket of the hydraulic line; and corrective actions if necessary. We are proposing this AD to detect and correct broken support brackets of the hydraulic lines, which could result in inadequate clearance between the IDG power cables and hydraulic lines and chafing of the IDG power cables, and consequent high energy arcing and an uncontrolled fire in the aft equipment bay.
Airworthiness Directives; Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2011-09- 03, which applies to all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G airplanes. AD 2011-09-03 currently requires repetitive eddy current inspections to detect cracks in the center wing upper and lower rainbow fittings, and corrective actions if necessary; and repetitive replacement of rainbow fittings, which would extend the repetitive interval for the next inspection. Since we issued AD 2011-09-03, analysis of in-service cracking has shown that a reduction in the inspection intervals is necessary for the upper rainbow fittings. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would require reduced intervals for inspections of the upper rainbow fittings. We are proposing this AD to detect and correct fatigue cracking of the upper and lower rainbow fittings on the center wings, which could grow large and lead to the failure of the fitting and a catastrophic failure of the center wing.

Notice of Industry Meeting
The Federal Aviation Administration (FAA) is hosting an industry day to introduce the Mini Global II project to the aviation community. The FAA will demonstrate that operational benefits to aviation stakeholders can be realized sooner, while also potentially identifying new synergistic technologies and capabilities.
Airworthiness Directives; Embraer S.A. Airplanes
We are superseding an airworthiness directive (AD) 2013-22-20 for Embraer S.A. Model EMB-505 airplanes. 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 cracks beyond acceptable limits in the carbon discs of the left hand (LH) and right hand (RH) brake assemblies. We are issuing this AD to require actions to address the unsafe condition on these products.
