Scope

This part of ISO 16049 specifies utilization guidelines and principles to be used in strength calculation methods adequate to guarantee the effectiveness and ultimate load strength of tie-down/lashing arrangements used to restrain cargo on board civil transport aircraft during flight for either: a) cargo loaded and tied down onto airworthiness certified air cargo pallets, themselves restrained into aircraft lower deck or main deck cargo systems meeting the requirements of ISO 8097; b) additional tie down on aircraft structure when necessitated by pallet maximum gross mass or centre of gravity limits; c) non-unitized individual pieces of cargo, or pieces of cargo placed onto an unrestrained ("floating") pallet into either lower deck or main deck containerized cargo compartments of an aircraft; or d) individual pieces of load loaded in non containerized (bulk loaded) baggage or cargo compartments. This part of ISO 16049 is applicable to cargo tie-down/lashing arrangements using exclusively air cargo restraint straps conforming to ISO 16049-1. Its general recommendations may be used for tie-down arrangements using other means (e.g. steel cables, rope, chains, other types of straps), but under the user's responsibility as to their adequacy and the strength calculations required. This part of ISO 16049 is not applicable to the use of chains or other rigid devices for tie-down onto civil transport aircraft floor tracks. These devices are generally not recommended for use due to the possibility of generating excessive stresses in the aircraft structure, except where explicitly approved in the manufacturer's Authority approved Weight and Balance Manual. This part of ISO 16049 is intended to provide industry recognized means of complying with Airworthiness Authorities general regulations applicable to load-securing on board civil transport aircraft (see FAR/JAR Parts 25), and aircraft manufacturers Authority approved Weight and Balance Manuals for each aircraft type as specified therein. It is not the intent of this part of ISO 16049 to specify when restraint straps should be used, but how they should be used. It does not, under any circumstance, supersede the requirements of any of the above documents that take precedence at all times.
