(8) Signaling systems. Signal systems between aircrew and ground personnel shall be understood and checked in advance of hoisting the load. This applies to either radio or hand signal systems.

(9) Helicopter refueling. Due to the load lifting abilities and capacities of individual models of aircraft flight with low fuel levels is common. It may become necessary to refuel the helicopter at the designated staging/lift area. Care must be given to ensure the aircraft is grounded per the manufacturer's recommendation during all refueling activities.

(10) Daily preflight briefing. Prior to each day's operation a job hazard assessment shall be conducted. This assessment shall set forth the plan of operation for all individuals involved in the helicopter external sling load lift. The preflight briefing shall include, but not be limited to, the following:

(a) Weather forecast and visibility for the day of the lift(s);

(b) Confirmation of flight path;

(c) Load lifting sequence;

(d) Individual load weights;

(e) Wind speed and direction monitoring;

(f) Ground crew responsibilities;

(g) Load receiving crew's responsibilities;

(h) Pilot's responsibilities;

(i) Communications/signaling;

(j) Aircraft fuel loading and refueling;

(k) Emergency plan for load jettison and landing.

(11) Lifting plan.

(a) The lifting plan shall at a minimum cover:

(i) Load identification;

(ii) Lifting sequence; and

(iii) Load orientation marks or tags.

(b) Loads that do not require upending shall be oriented in the same direction in the staging area as the laydown area. You must:

(i) Plan the layout of the staging area to avoid any light or unstable material that may blow around; and

(ii) Plan the lifting and flight path to avoid flying over employees and any material still being installed or not yet secure in the laydown area.

(12) Job hazard analysis/risk assessment. During the job hazard assessment, at a minimum, identify, assess, and eliminate or provide protection against risks posed by:

(a) Power lines;

(b) Cranes in the area;

(c) Structures, roof and structure profiles;

(d) Loose, unsecured material in staging or roof landing area;

(e) Temporary, unsecured structures in staging or landing area;

(f) Roof openings and roof access - Cover both to prevent building pressurization and to eliminate fall hazards;

(g) Unprotected roof edges;

(h) Pinch, crush, and similar danger points in the load/lift/land sequence;

(i) Weather conditions;

(j) Public safety.

(13) Rigging slings and inspection.

(a) Rigging slings for suspended external loads must consist of steel IWRC type slings at all direct connection points to the load being lifted.

(b) Synthetic slings may only be used in the intermediate length of the rigging between the direct steel sling and the cargo hook connection.

(c) The connection between the slings and the helicopter cargo hook must be a single steel rigging ring of either round or oval shape and must be of compatible shape and size to ensure immediate connection and release when the connection between the cargo hook and the ring is terminated by deliberate action of the pilot.

(d) All rigging components and assemblies shall have documented inspections each day before use.

(14) Tag lines.

(a) Tag lines must be used on all external sling loads.

(b) All tag lines shall be equipped at the end with a weight of sufficient size to assure that the line will not be induced into the main rotor or tail rotor under any operating condition.

(c) Hand spliced synthetic rope connections are not allowed in any helicopter external load operation.

(d) Tag line length shall be kept shorter than the load line length to assure the lines cannot be blown into the main rotors.

(15) Remotely operated cargo hooks.

(a) All cargo hooks shall have the electrical activating device so designed and installed as to prevent inadvertent operation.

(b) In addition, these cargo hooks shall be equipped with an emergency mechanical control for releasing the load.
