The purpose of this SAE Aerospace Standard (AS) is to standardize the basic design, performance, and testing requirements for “Cargo Stoppers” cargo tie-down accessories to be used in conjunction with approved restraint straps meeting AS5385C (TSO C-172) requirements.

This SAE Aerospace Standard (AS) specifies the testing methods to be used to substantiate performance of air cargo containers, pallets and nets (Unit Load Devices) for airworthiness approval in accordance with NAS 3610 or AS36100.

The present SAE Aerospace Information Report (AIR) provides a list of the main government regulations, SAE and international standards, and standing industry recommendations applying to air cargo unit load devices (pallets, nets, and containers) to be loaded with either baggage or freight on board civil transport aircraft. It is intended to provide unit load devices designers, purchasers, and operators as well as civil transport aircraft and aircraft cargo systems designers within the industry with a list of the available document references to cover the other aspects that do not all directly pertain to airworthiness and testing, listed in 1.1 of AS36100, – Air Cargo Unit Load Devices - Performance Requirements and Test Parameters [TSO-C90].

The tests are static in nature to minimize complexity and cost of required testing facilities. As far as practical, applied static loads should take into account the combined static and dynamic loads anticipated in service. It is intended that tests shall be non-destructive in nature and not result in damage unless ultimate load conditions are employed. Test equipment and methods of testing described are not meant to be restrictive. Alternate equivalent methods to accomplish the desired results may be employed. In selected cases, tests may be repeated under ultimate load conditions when required for substantiation of analytical data. If this becomes necessary, the parts deformed may be removed and replaced prior to the retest.

This SAE Aerospace Information Report (AIR) is intended to assist the user (aircraft manufacturer/airline) in the following areas: a In the decision of whether or not to plan for the installation of a powered drive system in the cargo loading system (CLS) during the definition of the aircraft on-board cargo loading system. b If a powered drive system is decided upon, to provide general requirements to be considered during the preparation of component specifications for the powered drive units (PDUs) to be used. This provides a selection of criteria in order to obtain an optimum PDU for the application considered.

Since cargo restraint devices made with textiles should have a predictable service life, there should be data available so that predictions can be made. This document compiles available information on textiles of the types used in air cargo restraint devices and reviews the degradation characteristics of each. Textiles are used primarily in cargo restraint nets on air cargo pallets and nonstructural containers, restraint nets installed in cargo aircraft, and similar applications.

Air cargo pallets and their cargo restraint nets constitute aircraft Unit Load Devices, defined by industry standards and airworthiness certified based on Technical Standard Order (TSO) C90c in accordance with the requirements of NAS 3610. This guarantees their design to be intrinsically safe for flight on board compatible aircraft types. However, actual flight safety also requires these certified pieces of equipment to be properly used: numerous occurrences have demonstrated a certified ULD can nevertheless jeopardize flight safety if loaded or restrained in an inadequate manner.

This Aerospace Information Report (AIR) provides a record of the development by SAE AGE-2A Air Cargo Sub-Committee of Aerospace Standard AS36100, Air Cargo Unit Load Devices — Performance Requirements and Test Parameters, published 2005-02, and its revision A published 2006-04, intended as a technical reference for airworthiness approval of air cargo unit load devices (pallets, nets and containers) to be loaded with either baggage or freight on board civil transport aircraft, and to partly supersede previously used NAS 3610, Cargo unit load devices - Specification for — [ Revision 10, 1990, referenced in TSO C90(c) ].

This SAE Aerospace Information Report (AIR) provides instructions for intended proper use of Aerospace Standard AS36100A, published 2006-04 [TSO pending], as the technical reference for airworthiness approval of air cargo unit load devices (pallets, nets and containers) to be loaded on board civil transport aircraft. For consistency and cross-checking purposes, it also includes instructions for proper use of previous NAS 3610 [Revision 10, 1990, referenced in TSO C90c], as commonly understood by the industry.

This SAE Aerospace Standard (AS) covers the design, fabrication, performance and operational testing requirements for lower deck containers for use in main line aircraft which do not require airworthiness certification when loaded under the conditions of compartment restraint and in accordance with the aircraft's Weight and Balance Manual and/or, where applicable according to the aircraft type's approved Weight and Balance Manual, AS36100A or NAS 3610 equivalent base plate restraint for these containers. Most sizes of containers covered by this document (base sizes K, L, P, and Q) cannot physically be loaded and latched on aircraft main deck cargo systems. Base size A and M containers can, but are not allowed on aircraft main decks, which do not accept non-certified units. Accordingly, all containers covered by this document are to be used/installed exclusively in aircraft lower deck compartments.

This SAE Aerospace Standard (AS) provides dimensional, structural and environmental requirements for pallet nets to be used in conjunction with 2.44 m (8 ft) wide pallets described in AS1130. The pallet/net combination are used in freighter versions of certificated aircraft equipped to provide restraint to pallets tested to the requirements of NAS 3610 Class II restraint system. The minimum essential criteria are identified by use of the key word "shall". Recommended criteria are identified by use of the key word "should", and while not mandatory, are considered to be primary importance in providing serviceable, economical, and practical air transport pallet nets. Deviation from recommended criteria should occur only after careful consideration, extensive testing, and thorough service evaluation have shown alternate methods to be satisfactory.

In accordance with § 4.11 of AS36100, materials used in the construction of pallets, nets, and containers shall take into account the effects of environmental conditions, such as temperature, humidity, and UV degradation, expected in service. In accordance with (E)TSO-C90, the applicant shall consider environmental degradation due to aging, ultra-violet (UV) exposure, weathering, etc., for any materials used in the construction of pallets, nets, and containers. The purpose of this Aerospace Recommended Practice (ARP) is to provide guidelines for the basic requirements to be considered regarding environmental degradation effects when qualifying composite materials in the design to fulfill the (E)TSO-C90 Minimum Performance Standard. Material qualification is the verifying of a materials attributes and characterizations, which are typically determined through testing.

This Aerospace Recommended Practice aims at providing general utilization guidelines and calculation methods adequate to guarantee the effectiveness and ultimate load strength of tie-down/lashing arrangements performed to restrain cargo on board civil transport aircraft during flight: a Cargo loaded and tied down onto airworthiness approved air cargo pallets, themselves restrained into aircraft lower deck, main deck or upper deck cargo systems meeting the restraint requirements of air cargo pallets approved in accordance with NAS 3610 or AS36100, or b Additional tie-down on aircraft structure when necessitated by pallet maximum gross mass or centre of gravity location, or c Individual pieces of cargo, or pieces of cargo placed onto an unrestrained (“floating”) pallet into either lower deck, main deck or upper deck containerized cargo compartments of an aircraft, or d Individual pieces of load loaded in non-containerized (bulk loaded) baggage or cargo compartments.
