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 correctly bonded, and the hoist is correctly bonded to the aircraft.

                  (iii)  Introduce mandatory fitment of an alternative cable cut cartridge
                  P/N Y1262-2-1 which has a minimum "NO FIRE" current twice that of the present cartridge thus increasing the level of safety; and

                  (iv)   Replace the existing single pole double throw cable cut switch fitted to some aircraft with a double pole double throw switch. This new configuration has been shown under actual Bell Test Conditions, to provide a significant increase in the level of EMI tolerance and safety.
              (v)     Amendment of the existing ICI Electric Fuse "no fire" test to provide for testing under simulated operating conditions using all likely radio equipment combinations. Because the ICI fuse is approximately 6 times more sensitive than the Y1265-2-1 explosive squib, this test should serve to demonstrate the EMI tolerance of the cable cut circuitry under actual operating conditions thus providing a basis for restored user confidence.
