Pilatus PC-6 Service Bulletin No. 32-002, Revision 2, dated April 29, 2008.
(2) If as a result the inspection required by paragraph (f)(1) of this AD any stiffness or limited movement of a brake pedal is found, before further flight, perform the corrective actions in accordance with the paragraph 3.C. of the accomplishment instructions of Pilatus Aircraft Ltd. Pilatus PC-6 Service Bulletin No. 32-002, Revision 2, dated April 29, 2008.
