AIR CONDITIONING – TRANSMITTAL OF KELLY AEROSPACE SERVICE BULLETIN KATS-SB-19-001 RUDDER CABLE CLEARANCE ON CESSNA T206H EQUIPPED WITH KELLY AEROSPACE THERMAL SYSTEMS AIR CONDITIONING PER STC SA03302CH

Updated on 2/25 with a new PDF after Textron issued SEL-21-03.

Kelly Aerospace has received reports that the rudder control cable can be caught on the air conditioning (AC) circuit board when the AC inlet assembly is installed or re-installed incorrectly. If a rudder control cable is caught on the circuit board, there is a possibility for the cable to cause arching when it contacts the terminals on the AC circuit panel. A rudder control cable that contacts the terminals on the AC circuit panel can arc with sufficient energy that the rudder control cable can be severed causing loss of rudder control and subsequently loss of control of the airplane.
