                equipped with an operator's belt (called "hoist operator's belt") part numbers 330A87-0730-00, 330A87-2371-00, 341A84-1120-00, 350A84-0047-00,

Requirement:       1. Action in accordance with paragraph 2.B. of Eurocopter Alert Service Bulletin (ASB) No. 45.06.

                   2. Remove the lever-type snap hook, part number GA343-95 or part number
                   4100-80AT28, and replace it with a quick-release shackle part number
                   365A84-5033-20, in accordance with paragraph 2.B. of ASB No. 25.11.

                   3. Modify the stock of operators' belts and lever-type snap hooks held as spares, in accordance with paragraph 2.B.6.a. and 2.B.6.b. of ASB No. 25.11.

                Note:  EASA AD 2006-0252 refers.
Compliance:        1. Before each use of the "hoist operator's belt"; until compliance with
                   Requirement 2.

                2. and 3.  Before 31 December 2006.
                This Amendment becomes effective on 26 October 2006.
Background:     Untimely unlocking of the "hoist operator's belt" was detected in operation.  This unlocking caused no incident and no injury.  As a precaution, and pending an upgrade to the belt design, this Directive requires certain actions before each use.

   Amendment 1 is issued in response to a new EASA AD which converts the Requirement 1 document to an Alert Service Bulletin with the same reference number, and requires the replacement of lever-type snap hooks with a quick-release shackle.
