To detect cracks and prevent possible misalignment of the rudder cable-pulley at the fuselage crossmember which supports the cabin entrance step, accomplish the following:

a. For airplanes with 500 or more hours in service on the effective date of this AD, within the next 100 hours in service, inspect the cabin entrance step supporting frame structure for cracks, repair as necessary in accordance with paragraph (c), and unless already accomplished incorporate additional bracketry for the footstep attachment at the rudder pulley in accordance with paragraph (c).

b. For airplanes with less than 500 hours in service on the effective date of this AD, before the accumulation of 600 hours in service, inspect the cabin entrance step supporting frame structure for cracks, repair as necessary in accordance with paragraph (c), and unless already accomplished, incorporate additional bracketry for the footstep attachment at the rudder pulley in accordance with paragraph (c).

c. Accomplish steps 1 through 5 under the "Inspection and Repair Instructions" Section and steps 1 through 9 under "Footstep Reinforcement Brackets Installation Instructions" in Piper Service Bulletin No. 672 dated June 20, 1980, or equivalent.

d. Equivalent inspections and alterations must be approved by the Chief, Engineering and Manufacturing Branch, FAA Eastern Region.

e. Upon submittal of substantiating data by an owner or operator through an FAA Maintenance Inspector, the Chief, Engineering and Manufacturing Branch, FAA, Eastern Region, may adjust the compliance times specified in this AD.

NOTE: Since the cabin step is part of the approved type design, it must be in place. This includes those cases where temporary permission was granted for its removal.

Amendment 39-3992 was effective December 19, 1980.

This amendment 39-4198 is effective August 28, 1981.
