The airworthiness directive
49-49-01 LOCKHEED: Applies to All Model 49 Series Aircraft Equipped With Eclipse- Pioneer Model PB-10 Automatic Pilots.
Compliance required prior to reconnection in aircraft.
Prior to reconnection in the aircraft of the Eclipse-Pioneer Model PB-10 automatic pilot, it is necessary to modify the installation to include provisions designed to safeguard the aircraft in the event of malfunctioning of the autopilot. This modification has been determined to consist of the following interdependent changes:
Modify the master direction indicator and wiring at the autopilot controller plug and amplifier to change the direction signal from the rudder channel to the aileron channel; install resistors in series with the variable phase of aileron, rudder and elevator servo motors to reduce servo forces; install aileron servo disconnect interlock switch and change wiring to this switch from the existing rudder servo disconnect interlock switch.
An acceptable method of accomplishingthis modification is described in LAC Service Bulletin No. 49/SB-576.
This supersedes AD 49-36-01.
