What was found

BELL PITCH CHANGE LINK ANTIROTATIONAL BRACKETS CAME IN CONTACT WITH AIRCONDITIONER CONDENSER DURING A NORMAL LANDING, RESULTING IN BENT REPHAZING LEVERS (FLIGHT CONTROL). PROBABLE CAUSE: TRANSMISSION HAS A GREATER AMOUNT OF TRAVEL ON ITS PYLON MOUNTS, THAN THERE IS CLEARANCE BETWEEN ROTATING COMPONENTS AND FIXED CONDENSER. RECOMMENDATIONS: PROVIDE ENOUGH CLEARANCE TO CONDENSER, SO THAT TRANSMISSION MOVEMENT CAN NOT CAUSE CONTACT.
