(BHTI); CALIFORNIA DEPARTMENT OF FORESTRY; GARLICK HELICOPTERS; HAWKINS AND POWERS AVIATION; HERCULES; INTERNATIONAL HELICOPTERS, INC.; LENAIR CORPORATION; OFFSHORE CONSTRUCTION; OREGON HELICOPTERS; PILOT PERSONNEL INTERNATIONAL; SMITH HELICOPTERS; SOUTHERN AERO CORPORATION; SOUTHWEST FLORIDA AVIATION; and WEST COAST FABRICATIONS: Amendment 39-8029. Docket No. 90-ASW-09. Final Rule of Priority Letter AD 90-03-10.

Applicability: All Model 204B, 205A, 205A-1, UH-1A, UH-1B, UH-1E, UH-1F, UH-1H, UH-1L, and TH-1L helicopters, certificated in any category, with aluminum tail rotor grips, P/N 204-011-728-19, installed.

Compliance: Required before further flight, unless already accomplished.

To prevent failure of a tail rotor grip, which could result in loss of tail rotor control, accomplish the following:

(a) Determine the part numbers and serial numbers of the tail rotor grips installed on the helicopter.

(b) If the tail rotor grip installed is P/N 204-011-728-19 and is identified with any serial number listed below, remove and replace the grip with an airworthy part before further flight:


Serial Numbers:	A3-66287	A3-66333	A3-66356
	A3-66361	A3-66365	A3-66370
	A3-66377	A3-67149	A3-67171
	A3-67184	A3-67207	
(c) In accordance with FAR Sections 21.197 and 21.199, the helicopter may be flown to a base where the inspection and grip replacement may be accomplished.

(d) An alternate method of compliance which provides an equivalent level of safety, may be used if approved by the Manager, Rotorcraft Certification Office, Southwest Region, Federal Aviation Administration, Fort Worth, Texas 76193-0170, telephone (817) 624-5170.

This Amendment (39-8029, AD 90-03-10) becomes effective on October 18, 1991, as to all persons except those persons to whom it was made immediately effective by Priority Letter AD 90-03-10 issued January 29, 1990, which contained this amendment.
