29、Throughout this document, 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 of primary importance in providing safe, economical and usable aircraft tow bars.
30、 Deviation from recommended criteria should only occur after careful consideration and thorough service evaluation have shown alternate methods to provide an equivalent level of safety.

31、 This document specifies dimensional and physical requirements of tow bar connections to tractor and aircraft (see Figure 1). It is applicable to any new type of commercial transport category aircraft tow bar designed or built after publication of this document. The purpose of this document is to st
32、andardize tow bar attachments to airplane and tractor according to the mass category of the towed aircraft, so that one tow bar head with different shear levels can be used for all aircraft that are within the same mass category and are manufactured in compliance with ISO 8267.

42、 its length; shall be designed to eliminate inadvertent disengagement of the tow bar during towing or pushing operations; shall be designed to provide adequate clearance during engagement and disengagement of the tow bar from the aircraft connection (allowable space envelope for clearance is specifi
43、ed in ISO 8267); and should be adjustable to provide pressure on the pin when locked.
