REGULATORY TEXT:  
83-20-01 GARLICK HELICOPTERS, HAWKINS & POWERS AVIATION, INC., WILCO AVIATION (BELL) MODEL UH-1B HELICOPTERS: Amendment 39-4731. Applies to Garlick Helicopters, Hawkins & Powers Aviation, Inc., and Wilco Aviation (Bell) UH-1B helicopters certified in all categories.

Compliance is required within the next 100 hours time in service after the effective date of this AD unless already accomplished.

To prevent excessive structural loads which could lead to mechanical failure and possible loss of a helicopter, accomplish the following:

(a) Inspect the tail rotor hub assembly and identify the part number of the tail rotor hub assembly. The tail rotor hub assembly part number is located on the yoke assembly.

(b) If the tail rotor hub assembly, P/N 204-011-801-003, is installed, remove and replace with P/N 204-011-801-005, 009, or 017.

(c) Any equivalent method of compliance with paragraph (b) above of this AD must be approved by the Manager, Aircraft Certification Division, Southwest Region, Federal Aviation Administration, P.O. Box 1689, Fort Worth, Texas 76101.

(d) In accordance with FAR 21.197, flight is permitted to a base where the inspections required by this AD may be accomplished.

This amendment becomes effective November 1, 1983.
