Compliance: Required as indicated, unless accomplished previously.
To prevent failure of the bearings, loss of a main rotor blade, and subsequent loss of control of the helicopter, accomplish the following:

(b) If a crack is found in the bearings, replace the affected bearings with an airworthy part before further flight.
(c) An alternative method of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Rotorcraft Standards Staff, FAA, Rotorcraft Directorate. Operators shall submit their requests through an FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Rotorcraft Standards Staff.
NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Rotorcraft Standards Staff.
(d) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the helicopter to a location where the requirements of this AD can be accomplished.
(e) The inspection and any necessary replacement shall be done in accordance with the applicable BHTI Alert Service Bulletin Nos. 222U-92-33 or 222-92-60, both dated December 16, 1992. This incorporation byreference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
