What was found
REASON FOR REMOVAL FAILED HYSTERESIS CHECK SUSPECTED AUTO PILOT PROBLEM. THE PROBLEM WAS WHEN THIS AIRCRAFT WAS DELIVERED THE HYD PACK HAD ANOTHER MFG SERVO ON IT. AND THE AUTO PILOT SYSTEM NEVER WORKED. SO FINALLY WE GOT THE RIGHT HYD PACK WITH THE FWM SERVO'S ON IT. WE ARE ASKING FOR WARRANTY ON THE ONE THAT WAS REMOVED AND THE NEW ONE THAT WAS INSTALLED. HARD CARDS ARE ENCLOSED.
