REGULATORY TEXT:  
86-01-07 HAMILTON STANDARD: Amendment 39-5209. Applies to Hamilton Standard model 54H60-77, -81, -123, -125, -131, and -133 propellers with propeller control S/N 850901 or lower installed on, but not limited to, CV580, L188 and Guppy aircraft.

Compliance is required within the next 30 days after the effective date of this AD, unless already accomplished.

To prevent loss of aircraft control and possible loss of aircraft, accomplish the following:

(a) Within the next 30 days after the effective date of this AD, conduct a functional check of the propeller valve housing cover input gear in accordance with Hamilton Standard 54H60 ASB No. 61-A119, Paragraph 2.A dated December 10, 1985, or FAA-approved equivalent.

(1) If the application of less than 36 pounds of load causes slippage of the input lever, remove the valve housing cover assembly prior to further flight.

(2) If 36 to 38 pounds can be maintained without slippage of the input lever, mark the valve housing cover in accordance with Paragraph 2.D.(1) and return to service.

(b) At the next component maintenance/propeller overhaul after completing the above functional check or by January 15, 1988, whichever occurs sooner, inspect the valve housing cover in accordance with Paragraphs 2.B and 2.C of 54H60 ASB No. 61-A119. Remove from service all input gears with change letter "G" indicated and replace with a serviceable gear. Mark the valve housing cover in accordance with Paragraph 2.D.(2).

Aircraft may be ferried in accordance with the provisions of FAR 21.197 and 21.199 to a base where the AD can be accomplished.

Upon request, an equivalent means of compliance with the requirements of this AD may be approved by the Manager, Engine and Propeller Standards Staff, ANE-110, Federal Aviation Administration, 12 New England Executive Park, Burlington, Massachusetts 01803.

Upon submission of substantiating data by an owner or operator through an FAA maintenance inspector, the Manager, Engine and Propeller Standards Staff may adjust the compliance time specified in this AD.

Hamilton Standard 54H60 ASB No. 61-A119, dated December 10, 1985, is incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1).

All persons affected by this directive who have not already received this document from the manufacturer may obtain copies upon request to Hamilton Standard, Division of United Technologies Corporation, Windsor Locks, Connecticut 06096. This document also may be examined at the Office of the Regional Counsel, Attn: Rules Docket 85-ANE-48, Federal Aviation Administration, 12 New England Executive Park, Burlington, Massachusetts 01803.

This amendment becomes effective on January 17, 1986.
