ROTORCRAFT FLIGHT MANUAL SUPPLEMENT

the open position to facilitate loading by a ground crew. The cargo hook interfaces with the rotorcraft’s manual release system as supplied by Bell. Consult the Flight Manual Supplement – Cargo Hook for operation of manual release system. 7. Cycle the cargo hook’s electrical release mechanism to ensure proper operation. Pressing the CARGO RELEASE switch on cyclic should cause the cargo hook load beam to open. The cargo hook may be returned to the locked position by manually pushing up on the load beam. The load beam should snap shut. The cargo hook interfaces with the rotorcraft’s electrical release system as supplied by Bell. Consult the Flight Manual Supplement – Cargo Hook for operation of the electrical release system.

Move the cargo hook and the suspension system throughout their full ranges of motion to ensure the manual release cable and electrical harnesses have enough slack. The cable or electrical harnesses must not be the stops that prevent the cargo hook or suspension from moving freely in all directions. 9. Move the cargo hook back and forth on the suspension beam to ensure that it rolls freely and that there are no obstructions within the beam. When an Onboard Systems 200-259-00 or 200-259-01 Cargo Hook Suspension System with Load Weigh is installed, perform the following additional procedure: 1. Zero the load weigh system or tare the weight on the cargo hook that is not wanted, such as the weight of a cargo net or long line, by depressing the zero button on the indicator.

NORMAL PROCEDURES continued Cargo Hook Rigging Extreme care must be exercised in rigging a load to the Cargo Hook. The following illustration shows the recommended rigging configuration and rigging configurations to avoid. The example shown is not intended to represent all possibilities. It is the responsibility of the operator to ensure the hook will function properly with the rigging. Nylon Type Straps or Rope Nylon type straps (or similar material) or rope must not be used directly on the cargo hook load beam. If nylon straps or rope must be used they should be first attached to a steel primary ring. Verify that the ring will freely slide off the load beam when it is opened. Only the primary ring should be in contact with the cargo hook load beam. See Figure 2.

NORMAL PROCEDURES continued Trailing Loads The suspension system is designed to accommodate loads through an angle of up to 55° from vertical —both forward and aft. However, when loads exceed 55°, the travel stops on the Pillow Blocks prevent the Suspension Beam from further rotation and cause bending stresses to be carried by the Load Cell. Care should be taken to avoid this flight regime. The situation is most likely to occur when flying at high speeds with light loads, which have large aerodynamic drag, for example - an empty fire or fertilizer bucket or an empty long line. Figure 3 illustrates the adverse loading situation. Page 13 of 14 Rev. 3 Bell 206L/407 Suspension System Rotorcraft Flight Manual Supplement Document Number 121-003-00 FAA Approved 2.

EMERGENCY PROCEDURES The Rotorcraft Flight Manual Supplement – Cargo Hook issued by Bell remains applicable. 4. PERFORMANCE The Rotorcraft Flight Manual Supplement – Cargo Hook issued by Bell remains applicable. When an Onboard Systems 200-259-00 or 200-259-01 Cargo Hook Suspension System with Load Weigh is installed the following applies. The Load Weigh System is designed and installed as a means of MONITORING the load (weight) suspended from the cargo hook. Functional and performance characteristics have not been determined on the basis of the load cell indication or display. Therefore, this instrument shall NOT be used as a primary indication of performance and flight operation must NOT be predicated on its use.
