Eurocopter AS 332 (Super Puma) Series Helicopters AD/S-PUMA/55 Amdt 1 BREEZE Hoist Hooks 6/2005 Applicability: Model AS 332 C, C1, L, and L1 helicopters, equipped with Breeze hoists fitted with hook assembly part number BL-7520-01; with hook part number BL-7520. Note: The affected hook is not fitted with a tongue locking system. Requirement: 1. Accomplish the operational procedure, and the restriction prohibiting the use of straps, in accordance with the instructions specified in paragraph 2.A. of Eurocopter Alert Service Bulletin No. 01.00.70. 2. Accomplish the instructions specified in paragraph 2.B. of Eurocopter Alert Service Bulletin No. 01.00.70. Note: DGAC AD F-2004-170 R1 refers. Compliance: 1. Before each hoisting operation. 2. Within 2 months after 10 November 2004. The compliance times remain unchanged by this issue. This Amendment becomes effective on 9 June 2005. Background: This Directive was prompted by a case of incorrect positioning of the strap on the hoist hook during a hoisting operation, which led to distortion of the tongue and resulted in the release of the stretcher. Amendment 1 is issued in response to a revision of the related DGAC AD, which converts the Requirement document to an Alert Service Bulletin; with no change to the technical content.
