## Discrepancy

DURING EXTERNAL LOAD OPERATIONS, THE AIRCRAFT TAIL ROTOR PEDALS MALFUNCTIONED. PILOT WAS ABLE TO PERFORM A RUN-ON LANDING WITH NO INJURIES OR DAMAGE TO THE AIRCRAFT.
AIRCRAFT IS OPERATED FROM THE LEFT HAND CREW SEAT DURING EXTERNAL LOAD OPERATION USING PARAVION LEFT SEAT PILOT CONFIGURATION - STC NO. SR00486DE.
A DART AEROSPACE LTD. TAIL ROTOR PEDAL LOCKOUT KIT P/N D119-827-011 IS INSTALLED ON THE LEFT HAND TAIL ROTOR PEDAL ASSEMBLY P/N 206-001-713-105 PER STC NO. SR02258SE.
DURING INSPECTION AFTER THE LANDING, IT WAS FOUND THAT THE PIN HAD DETACHED FROM THE CAM ARM OF THE DART AEROSPACE EXPANDABLE PIN ASSEMBLY P/N D4704-041 AT THE R/H PEDAL, CAUSING LINK P/N 206-001-701 TO SEPARATE FROM BELLCRANK P/N 206-001-702-009. 
EXPANDABLE PIN ASSY NEEDS RE-DESIGN TO INCLUDE A MORE POSITIVE WAY OF RETAINING THE PIN TO THE CAM HANDLE.
