When operating above 6400kg (internal loads) the following Life Penalty Factor must be mandatorily applied to every flight (from take off to landing) any time the weight exceeds 6400kg during the flight.
To use the factor multiply the actual flight time (from take off to landing) by the stated factor. For example, the flight commenced at 6,500kg at 10.00 and landed one hour later at 11.00. The flight time was 1.0 hour and the factored time is 1 x 4.5 = 4.5 hours to be recorded on the component log card. Where landings are recorded multiply the number of landings by the stated factor.
Part Life Penalty Factor
Rod end (Fin End) 4.5
Rod End (Tailplane End) 4
Taliplane Assy 4
Main Rotor Blade Assy 2
Main Rotor Damper 2
MGB Case, Top Assy 1.6
MGB Upper Fitting 2 (landings)
Tail Rotor Hub Assy 1.25
Tail Rotor Shaft Drive Assy No. 2 2 (Landings)
Tail Rotor Shaft Drive Assy No. 3 2 (Landings)
For External Hoist Operations the same principle applies with the following Life Penalty Factors:-
Main Rotor Rotating Swashplate 0.5
MGB Shaft, Main Rotor Penalty deleted*
*Note that component lives penalised using the previous factor (2.5) can be recalculated using the formula,
present total accumulated life -2.5 x No. Accumulated External Hoist Lifts
Other Penalties are specified for Cat A Training Operations, starting and stopping the rotor in windspeeds greater than 27 kts and External Load Operations.
