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.

        CAUTION: Do not allow the fuse connections to contact each other or any part of the aircraft structure.

            b.    Reset the hoist control and cable cut circuit breakers, then with the aircraft engine running, all normal operational equipment selected, and using full rated hoist load:

              1. Ensure correct operation of the UP and DOWN limit switches;

             2.    Inch the hoist a number of time (i.e. 10-12 times) in both directions; and

             3.    Operate all radios and key all transmitters in the aircraft both in isolation and in combinations; operate all optional and non essential equipment in all likely combinations.

            The ICI Electric Fuse MUST NOT fire during the above tests.

        CAUTION: Before testing or firing the 1.8 metre ICI Electric Fuse ensure that no flammable vapours are present and that no person is within 1 metre of the fuse.
                c.    Operate the cable cut switch and check that the ICI Electric Fuse has fired - The fuse should explode with a "sharp crack" similar to the igniting of a large match - Ensure that the cable cut switch is returned to the OFF position.

                d.    Shut down the aircraft engine. Disconnect the ICI Electric Fuse leads, and reconnect the positive (+Ve) wire and negative (-Ve) wire to the cable cutter cartridge.

            Note: ICI 1.8 metre Electric Fuses (Also known as "Match Head" fuses) are available in al capital cities at ICI Explosives Sales Offices.

 Compliance: Requirement 1:

            Before further flight after 6 March 1992. Requirements 2 to 8 (inclusive):
            Before a Breeze BL 16600 series hoist can be reactivated for use. Requirement 9:
                1. Before a Breeze BL 16600 series hoist can be reactivated for use;

b.    After any modification to the aircraft which may affect the integrity of the cable cutter system; and/or

c.    After any electrical modification to the hoist system.

            Following further investigation by Breeze, Bell and this Department, Amendment 2 to this Directive has been issued to:

                1. Ensure that all Breeze BL 16600 series hoists fitted to aircraft are disabled and not used unless both the hoist and the aircraft to which it is fitted comply with all applicable Requirements of this Directive; and

b.    Consolidate existing Requirements and introduce additional safety measures (summarized below) considered necessary to maximize the level of operational safety of the cable cut circuitry and thus restore user confidence in the cable cut system:

                  (i)       Ensure the cable cut circuit shielding is correctly connected;

                  (ii)     Ensure the component parts of the hoist are
