Compliance required prior to further flight, unless already accomplished, for all aircraft at a servicing facility. Aircraft located in a non-servicing area may be flown to a service area for compliance with this airworthiness directive after the pilot has inspected the three rudder horn attach bolts for adequate tightness.
To prevent loss of the rudder control system, accomplish the following:
1. Remove the three bolts which attach the rudder control horn to the rudder. (Reference Piper PA-36 Service Manual, Section IV, Figure 4-3, page 4-7, Sketch "G".)
2. Verify that all three bolts are AN3-6A, Piper P/N 400440. (Note: Shank length is 25/32 minimum to 13/16 maximum.)
3. If incorrect bolts are found, replace with AN3-6A with one AN960-10 washer, Piper P/N 407564, under the head of each bolt and torque to 20 to 25 inch-pounds. Make appropriate log book entry.
4. If bolts removed are AN3-6A, reinstall with one AN960-10 washer under the head of each bolt and torque to 20 to 25 inch-pounds. Make appropriate log book entry.
