Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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:
Airworthiness Directives; Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), Model CL-600-2D15 (Regional Jet Series 705), and Model CL-600-2D24 (Regional Jet Series 900) Airplanes

Airworthiness Directives; Bell Helicopter Textron, Inc. Model 212 Helicopters
Document Number: 2011-8133
Type: Rule
Date: 2011-04-06
Agency: Federal Aviation Administration, Department of Transportation
We are superseding an existing emergency airworthiness directive (EAD) for the Bell Helicopter Textron, Inc. (Bell) Model 212 helicopters with a certain main rotor hub inboard strap fitting (fitting) installed. That EAD requires, before further flight, removing certain serial-numbered fittings and replacing them with airworthy fittings. It also requires performing a magnetic particle inspection (MPI) on fittings with certain serial numbers (S/Ns) to inspect for a crack. If a crack is found, the cracked fitting must be replaced with an airworthy fitting, and certain data must be reported to the FAA. This airworthiness directive (AD) retains the requirements of that EAD and expands the applicability to require performing an MPI for a crack on additional serial-numbered fittings. This AD is prompted by the determination that certain fittings were not manufactured in accordance with the approved manufacturing processes and controls. In total, eight fittings have been found that have cracks. We are issuing this AD to prevent failure of a fitting, loss of a main rotor blade, and subsequent loss of control of the helicopter.
