Inspect for interference or inadequate clearance between the flight control mechanism and any component located forward of the instrument in accordance with Raytheon Mandatory Service Bulletin (SB) 27-3232 dated March 1999.\n\n\n \n\n2.    If interference or inadequate clearance is found during the Requirement 1 inspection then secure all components clear of the flight control mechanisms in accordance with SB 27-3232.\n\n \n\nNote 1.

Upon investigation the cause was found to be electrical/avionics wiring located forward of the instrument panel entangled in the flight control system “T” column.\n\n \n\n \n\n \n\n \n\n \n\n \n\n \n\n \n","sortOrder":0}],"analysis":{"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The Directive's scope is limited to the listed Beechcraft models and serial numbers and to inspecting/securing wiring near flight controls as set out in the Requirement and Compliance sections.
