UNDERWAY REPLENISHMENT NWP 4-01.4 - Historic Naval Ships ...

NWP 4-01.460 inches (152.4 cm). The roller conveyors limit palletweight to 2,200 lb (998 kg); a maximum of seven palletscan be carried simultaneously. Cabin width is 90 inches(228.6 cm) and cabin height varies between 73 inches(185.4 cm) and 77 inches (195.6 cm). These limits are forgeneral planning only. For detailed guidance, consult thecrew chief, CH-53E NATOPS manual, or loading manual.It will normally require 20 to 30 minutes to fullyoff-load or on-load a CH-53E with properly palletizedcargo or other large items of cargo. Cargo consisting ofsmall pieces, such as mail, will take longer due to addedmanpower and handling requirements.Due to limited tail boom clearance, a low-profile, 4-to 6-ton forklift is required when loading pallets andheavy or oversized items. The recommended vehicle is:Truck, lift, fork, diesel, shipboard, low silhouette, solidrubber tires, 6,000 lb (13,227.6 kg), 92-inch (233.7 cm)lift, Model Number 60-DALS-2.At no time shall the aircraft be configured to precludesafe emergency egress by the passengers and crew.10.15.4.1 Hazardous Cargo. Hazardous cargomust be prepared, briefed, and shipped per NAVSUP 505.10.15.4.2 Liquid Oxygen Carts. Liquid oxygencarts are extremely dangerous to carry in helicopters.They will not be carried unless directed by type commandersor higher authority, and only when requireddue to operational necessity.10.15.5 External Cargo Transport. Due to its externallift capability and single-point and dual-pointsuspension systems, the CH-53E is the most capablehelicopter for carrying heavy external loads over longdistances. External heavy lift operations with theCH-53E produce unique safety hazards of high staticelectric shock and rotor downwash. For all externalcargo operations, ground hookup and deck crews willbe thoroughly briefed on these hazards.10.15.5.1 Special Handling Equipment. To reducethe static electric shock hazard, use shock resistantrubber gloves, ASTMD-120-84A, Type I, Class III, anduse only the grounding wand.10.15.5.2 External Cargo Handling Procedures.External VERTREP safety procedures mustbe observed. CH-53E external VERTREP operationsalso require the following specific precautions:1. External cargo loads should weigh over 2,000 lb(907 kg). If loads are under 5,000 lb (2,268 kg)and transfer is not limited by range, consider usingan H-46 helicopter.2. Load positions on deck should be aft of theVERTREP tee-ball line for single-point loadsand at least an additional 5 feet (1.5 m) aft forclearance for dual-point loads.3. Class 5 VERTREP ship decks may require additionalpendants from the helicopter to allow sufficientrotor clearance for pickup or drop. Priorplanning is required.4. Dual-point lift operations shall be performedonly with the approved 7-foot 6-inch (2.3 m)dual-point pendant and swivel-hook assembly.5. Loads shall never be hooked to only one of thedual-point hooks, nor will one or both of thedual-point hooks be used in conjunction with thesingle- point hook.6. For dual-point cargo lifts, the load’s cG should beas equally balanced as possible and shall neverexceed a maximum of 60 percent on either hook.A practice dead lift by crane using dynometers onthe sling legs should be done on all special loadsto determine that proper rigging, cG, and flightstability requirements will be met.7. Ensure that special lifting equipment and attachingpoints are certified for use with helicopters.Dockside lifting equipment is not recommendedfor external cargo operations.8. Additional information may be found in theCH-53E NATOPS manual.10.15.6 Aircraft Recovery. Because of its dualpointsuspension system, the CH-53E is the primary aircraftrecovery helicopter. Aircraft recovery operationsrequire extensive planning, coordination, and preparation.10.15.7 Safety. Several unique hazards are associatedwith the CH-53E helicopter. These should bethoroughly reviewed and briefed to all flight deckcrew members to any VOD operation.Safety procedures unique to CH-53E operations andnot previously mentioned include:1. Recommended action for a ground crew memberwho is inadvertently engulfed in high velocitydownwash is to drop to the deck in a sitting orprone position.10-32 ORIGINAL
