REGULATORY TEXT:  
81-05-04 DOWTY ROTOL: Amendment 39-4132. Applies to Dowty Rotol (c)R.289/3-110- F/1 and (c)R.289/3-110-F/11 propellers installed on the WSK-Pezetel Model PZL-3S engine used on Gulfstream American (formerly Grumman) Model G-164A, B, C airplanes modified by STC SA2731SW, and Ayres (formerly Rockwell) Model S2R-R3S, and Model S2R airplanes modified by STC SA3897WE.

Compliance is required as indicated unless previously accomplished. To preclude the possibility of blade tip failures, accomplish the following:

Within the next 10 hours time in service after the effective date of this AD, install in the cockpit as near the engine tachometer as possible and in clear view of the pilot a placard which reads, "AVOID MP ABOVE 26 IN. HG. BELOW 2000 RPM." The placard may be fabricated locally, using 3/32 inch high lettering on a contrasting background.

Upon request of the operator, an equivalent means of compliance with the requirement of this AD may be approved by the Chief, Engineering and Manufacturing Branch, FAA, Great Lakes Region.

This Airworthiness Directive supersedes AD 80-15-09.

This amendment becomes effective June 15, 1981, as to all persons except those to whom it was made immediately effective by the priority mail letter dated February 26, 1981, which contained this amendment.
