 Breeze Hoists 3/92

 Applicability: All Breeze BL 16600 series hoists installed in helicopters.

             Requirement: 1. Deactivate hoist by pulling and locking the hoist control and cable cut circuit breakers so that inadvertent reset is not possible.

            Note: Requirements 2 to 8 inclusive must be carried out with all electrical power removed from the aircraft.

             2.    Clearly identify the polarity of the terminals and cables on the existing cable cut cartridge (i.e. +Ve and -Ve) so that correct connection is self evident.

             3.    Replace the existing cartridge with alternative, low sensitivity cartridge P/N Y1265-2-1.

             4.    For Bell 206A, 206B, 206B1, 206B111 and Agusta Bell 206B aircraft:

                1. Ensure the cable cut circuit shielding is correctly connected in accordance with Bell ASB 206-81-15 Rev A.

b.    Ensure the hoist is electrically grounded in accordance with Bell ASB 206-81- 15 Rev A.

c.    Ensure the earth wire on the cable cut switch introduced by AD/BELL 206/87 has been disconnected or removed.

d.    Replace existing cable cut single pole double throw switch with double pole double throw switch in accordance with Bell ASB 206-87-36 Rev A.

            Note: Agusta ASB 206-180 also refers.

             5.    For Bell 206L-1 and L-3 aircraft:

                1. Ensure that the cable cut circuit shielding is correctly connected as per Bell Helicopter Australia Drawing No 206-899-863B1 and rectify where necessary.

b.    Ensure the hoist is electrically grounded in accordance with Bell ASB 206L-81- 25.

c.    Replace existing cable cut single pole double throw switch with double pole double throw switch in accordance with Bell ASB 206L-87-46.

          6.    For Bell 222 aircraft:

            1. Ensure the hoist is electrically grounded in accordance with Bell ASB 222-81-9.

            b.    Remove the earth wire from the cable cut switch.

            c.    Replace the existing single pole double throw cable cut switch with a double pole double throw switch in accordance with Bell ASB 222-86-38.

          7.    For Hughes Helicopters:

            1. Inspect the cable cut circuit shielding to ensure that it is connected as per Hughes basic handbook of maintenance Group 10.

             2. Ensure hoist assembly is electrically bonded in accordance with AD/SUPP/16.

           1. For all other helicopter types ensure the cable cut circuit shielding is correctly connected, and ensure the hoist is electrically bonded in accordance with AD/SUPP/16.

           2. Verify the integrity of the hoist cable cut circuitry by testing as follows:

                 1. Remove the positive (+Ve) wire from the cable cut cartridge and connect it to one lead of an ICI 1.8 metre Electric Fuse. Remove the cartridge negative
            (-Ve) wire and connect it to the remaining fuse lead. This means that the Electric Fuse is now in the circuit, and the cable cut cartridge is disconnected from the system.
