What was found
INSTALLED VARIOUS RADIOS IN THIS AIRCRAFT INCLUDING THE GTX 330 TRANSPONDER INTO THE LOWER SECTION OF THE CAPTAINS INSTRUMENT PANEL. MONTHS LATER, WHILE THE AIRCRAFT WAS UNDERGOING A PHASE 5 INSPECTION AT THE MFG, IT WAS DISCOVERED THAT THE NEWLY INSTALLED TRANSPONDER WAS INTERFERING WITH THE RUDDER BELLCRANK ABOVE THE PILOTS RUDDER PEDALS AND PREVENTING THE RUDDER FROM ACHIEVING FULL TRAVEL TO THE LEFT. THE LOSS OF TRAVEL WAS IDENTIFIED AS BEING 6 DEGREES DURING A FLIGHT CONTROL (THROW) CHECK. REMANUFACTURED THE PANEL AND RELOCATED THE NR TRANSPONDER TO A MORE APPROPRIATE LOCATION WITH ADEQUATE CLEARANCE.
