Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to certain Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC- 12/45 airplanes. This AD requires removing the ``Alternate Flap System'' from the airplane flight controls and inserting a temporary revision that specifies this change in SECTION 2--LIMITATIONS of the PC-12 Pilot's Operating Handbook. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified by this AD are intended to preclude improper use of the ``Alternate Flap System'', which could result in flap asymmetry with consequent reduced or loss of control of the airplane.
