ASME B30.12-2006 pdf download.Handling Loads Suspended From Rotorcraft.
SECTION 12-0.1: SCOPE OF B30.12 This Volume applies to the protection of flight crews, ground personnel, and property on the surface while working directly with or in the vicinity of rotorcraft conducting external load operations. Within the general scope as defined in Section I, B30.12 applies to the han- dling of loads suspended from rotorcraft using a cargo sling or powered hoist, or other attaching means, to lift, carry, pull, or tow a jettisonable load outside of the rotorcraft airframe. SECTION 12-0.2: DEFINITIONS 12-0.2.1 Rotorcraft External Load Classifications Class A Rotorcraft External Load: a load combination in which the external load cannot move freely, cannot be jettisoned, and does not extend below the landing gear. This category usually features multiple attachments to the airframe. A typical example is a hard-mounted cargo basket attached to the rotorcraft airframe that is used to carry cargo from points A to B (included for reference only). Class B Rotorcraft External Load: a load combination in which the external load is jettisonable and lifted free of land or water during the rotorcraft operation. The load is typically suspended from a hook or similar device. The hook may be attached to the rotorcraft structure, or it may be attached to a movable hoist cable and the hoist itself attached to the rotorcraft. Typical use is to lift a cargo load until it is completely airborne and fly it from points A to B. Class C Rotorcraft External Load: a load combination in which the external load is jettisonable and remains in contact with land or water during rotorcraft operation. The load is typically incontactwithland or water during rotorcraft operation. The load is typically partially sus- pended by a net, slings, or cables from a cargo hook or similar device.
Class D Rotorcraft External Load: a load combination in which the external load is other than a Class A, B, or C and has been specificallyapproved bythe Administrator for that operation. This load combination includes human cargo. For human cargo operations, the load, which typically consists of personnel and their contain- ment device, is suspended from a hook or similar device during all or part ofthe flight. The hook may be attached to a movable hoist cable and the hoist itself rigidly attached to the rotorcraft. Typical use is for transfer of personnel to/from a ship. Carrying devices may trans- port one or more persons. Typical carrying devices are vest and straps, baskets, life preservers with straps and attachment devices, cages, or a suspended container. 12-0.2.2 General Definitions administrative or regulatory authority: governmental agency or the employer in the absence of governmental jurisdiction. administrator: the Federal Aviation Administrator or any person to whom he has delegated his authority in the matter concerned. aircraft: a device that is used or intended to be used for flight in the air. airframe: the fuselage, booms, nacelles, cowlings, fair- ings, airfoil surfaces (including rotors but excluding pro- pellers and rotating airfoils of engines), and landing gear of an aircraft and their accessories and controls. altitude, AGL: the height of a level, point, or object mea- sured in feet Above Ground Level (AGL). altitude, MSL: the height of a level, point, or object mea- sured in feet from Mean Sea Level (MSL). apex fitting: a ring or attaching device between the hook and sling and the supporting cables to the load. appointed: assigned specific responsibilities by the employer or the employer’s representative. attitude: the position of the rotorcraft or suspended load with reference to a horizontal position, such as nose up or down.
