This action updates the using agency information for restricted areas R-6602A, R-6602B, and R-6602C, Fort Pickett, VA. This is an administrative change to reflect the current organization tasked with using agency responsibilities for the restricted areas. It does not affect the boundaries, designated altitudes, time of designation or activities conducted within the restricted areas.
Airworthiness Directives; PILATUS AIRCRAFT LTD. Airplanes
We propose to adopt a new airworthiness directive (AD) for PILATUS AIRCRAFT LTD. Models PC-12, PC-12/45, PC-12/47, and PC-12/47E airplanes installed with an affected engine mounting frame assembly. 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 longitudinal material separation on the internal surface of the engine mounting frame assembly tubes. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model MD-90-30 airplanes. This proposed AD was prompted by reports of stick shaker activation at airspeeds that were above the stall protection system's stick shaker schedule. This proposed AD would require installing angle-of-attack (AOA) sensor external case heaters and AOA sensors, changing wires, and doing a functional test and applicable corrective actions. We are proposing this AD to correct water intrusion and subsequent ice formation between the AOA sensor vane and face plate, which could cause the vane to become immobilized. If the vane becomes immobilized, the stall protection system could become unreliable or non-functional, which could result in loss of control of the airplane.
Special Conditions: Ultramagic, S.A., Mark-32 Burner Series
This action proposes special conditions for the Ultramagic, S.A., balloon models F-18, H-56, H-65, H-77, M-56, M-56C, M-65, M-65C, M-77, M-77C, M-90, M-105, M-120, M-130, M-145, M-160, N-180, N-210, N- 250, N-300, N-355, N-425, S-70, S-90, S-105, S-130, S-160, T-150, T- 180, T-210, V-56, V-65, V-77, V-90, V-105, and Z-90. These models will have a novel or unusual design feature associated with having the new Mark-32 Burner series. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These final special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
