Aviation Weather Product Change: Transition of Select Area Forecasts (FAs) to Digital and Graphical Alternatives
The Federal Aviation Administration (FAA), in coordination with the National Weather Service (NWS), will transition seven (7) Area Forecasts (FAs), currently used as flight planning and pilot weather briefing aids, to digital and graphical alternatives. A joint-agency working group has concluded that these digital and graphical alternatives better-meet the needs of today's aviation users. Guidance with respect to the proper use of these alternatives is forthcoming.
Airworthiness Directives; Embraer S.A. Airplanes
We propose to adopt a new airworthiness directive (AD) for Embraer S.A. Model EMB-505 airplanes that would supersede AD 2013-22- 20. 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 cracks beyond acceptable limits in the carbon discs of the left hand (LH) and right hand (RH) brake assemblies. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Agusta S.p.A. Helicopters
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB412 and AB412EP helicopters with a certain rotor brake pinion installed. This AD requires inspecting the rotor brake pinion for a crack, and replacing it if there is a crack. This AD is prompted by a report of a rotor brake pinion failure. These actions are intended to detect a crack on the rotor brake pinion and prevent failure of the rotor brake pinion, which could lead to detachment of parts inside the transmission and subsequent loss of control of the helicopter.
Airworthiness Directives; Agusta S.p.A. (Agusta) Helicopters
We are adopting a new airworthiness directive (AD) for Agusta Model AB412 helicopters. This AD requires inspecting the main transmission lubricating system oil outlet hose (hose) for damage, and, if required, replacing the hose. This AD is prompted by reports of damage found on the hose. These actions are intended to prevent loss of main gear box (MGB) lubrication, which could lead to failure of the MGB and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron, Inc. (BHTI) Helicopters
We are superseding Airworthiness Directive (AD) 2003-01-04 for BHTI Model 204B, 205A, 205A-1, 205B, and 212 helicopters. AD 2003-01-04 required inspecting the main rotor grip (grip) and reporting certain inspection results to the FAA. AD 2003-01-04 also required performing additional inspections, repair, or replacement depending on whether a crack or delamination was found, and determining and recording the hours time-in-service (TIS) and the engine start/stop cycles for each grip on a component history card or equivalent record. This new AD requires the same actions as AD 2003-01-04 but adds a retirement life to certain grips and expands the applicability to include the Model 210 helicopter and additional part-numbered grips. This AD was prompted by the discovery of additional cracked grips. We are issuing this AD to prevent failure of a grip, separation of a main rotor blade, and subsequent loss of control of the helicopter.
