What was found
PILOT REPORTS HAVING AN AMBER GOVERNOR LIGHT IN FLIGHT. UPON AC SHUTDOWN, A FAILURE CODE WAS GENERATED INDICATING THE COLLECTIVE POTENTIOMETER WAS DEFECTIVE. A NEW PART WAS INSTALLED WITH NO FURTHER DEFECT REPORTED. THIS IS A RECURRING PROBLEM FOR THIS PART THAT HAS EFFECTED THE DISPATCH RELIABILITY FOR THIS MODEL AIRCRAFT. AS THIS DESIGN HAS SUCH A HIGH FAILURE RATE PERHAPS AN OPTIC DESIGN WITH NO CONTACT WITH A RESISTANCE RIBBON AS WITH THE CURRENT DESIGN SHOULD BE CONSIDERED. (K)
