REGULATORY TEXT:   83-06-07 WYTWORNIA SPRZETU KOMUNIKACYJNEGO, PZL-MIELEC: Amendment 39-4594. Applies to Model PZL M18 (all Serial Numbers through 1Z007-25) airplanes certificated in any category.

Compliance: Required as indicated, unless already accomplished.

To prevent loss of primary flight control about the yaw axis, accomplish the following:
a) Before the first flight of each day, visually check the rudder skin for cracks along the trailing edge. This check may be performed by the pilot.
1) If no cracks are found the airplane may be placed in service.
2) If cracks are found prior to further flight conduct the inspections of paragraph b).

b) Within 25 hours time-in-service after the effective date of this Airworthiness Directive (AD) and at 50 hours time-in-service intervals thereafter, using a 5-power magnifying glass inspect the rudder on both sides in the upper hinge area and along the trailing edge.
1) If no cracks are detected, return the aircraft to service.
2) If cracks are detected, remove the rudder and accomplish repairs as prescribed in paragraph III of Bulletin R/028/81.

c) The intervals between the repetitive inspections required by this AD may be adjusted up to 10 percent of the specified interval to allow accomplishing these inspections concurrent with other scheduled maintenance of the airplane.

d) Aircraft may be flown in accordance with FAR 21.197 to a location where this Airworthiness Directive (AD) can be accomplished.

e) An equivalent method of compliance with this AD if used must be approved by the Manager, Aircraft Certification Staff, AEU-100, Europe, Africa, and Middle East Office, FAA, c/o American Embassy, 1000 Brussels, Belgium.

This amendment becomes effective on April 4, 1983.
