标准范围

本文件规定了商用民用运输机常规三轮车式起落架前起落架上牵引杆附件配件的接口要求（当从前起落架执行牵引操作时）。其目的是通过飞机质量类别（决定牵引杆力）实现牵引杆连接配件接口标准化，以确保具有标准连接的单一类型牵引杆可用于该质量类别内或附近的所有飞机类型，从而协助运营商和机场处理公司减少使用的不同牵引杆类型的数量。本文件适用于规定最大坡道质量范围内的所有新型支线飞机，这些飞机在发布日期后投入使用或设计。它不适用于以前在役的支线飞机模型，该模型提供了相当多的牵引杆连接配件。然而，本文描述了一种简单的改装改装，可使某些在役配件与符合本文件要求的牵引杆头兼容，以方便此类机型在机场的运行。本文件适用于根据FAR/EASA-CS第25部分认证的最大坡道质量为≤ 50000公斤（110000磅）。它不适用于-根据FAR/EASA-CS第23部分认证为通勤类飞机的飞机适航性，以及-根据FAR/EASA认证的飞机适航性-CS第25部分，但最大坡道质量>；5万公斤（11万磅），这是ISO 8267-1所涵盖的。在一个现有或设想的飞机类型的家庭桥梁两个质量类别，使用一个单一的拖曳杆附件拟合接口的所有他们，并考虑使用标准尺寸的更高质量类别，它是本文件的一部分或ISO 8267？1，在整个家庭。注:就实际情况而言，本文件的定义是为了与相关质量类别中尽可能多的现有飞机类型兼容。

This document specifies the interface requirements for tow bar attachment fittings on the nose gear (when towing operations are performed from the nose gear) of conventional tricycle type landing gears of commercial civil transport aircraft.Its purpose is to achieve tow bar attachment fittings interface standardization by aircraft mass category (which determines tow bar forces) in order to ensure that a single type of tow bar with a standard connection can be used for all aircraft types within or near that mass category, so as to assist operators and airport handling companies in reducing the number of different tow bar types used.This document is applicable to all new models of regional aircraft within the specified maximum ramp mass range which enter service or are designed after its date of publication.It does not apply to previously in service regional aircraft models, which present a considerable variety of tow bar attachment fittings. However, a simple retrofit modification is described that may make certain in-service fittings compatible with a tow bar head in conformity with this document, where deemed appropriate in order to facilitate operation of such aircraft types at airports.This document is applicable to regional commercial transport aircraft airworthiness certified under FAR/EASA-CS Parts 25 with a maximum ramp mass of ≤ 50 000 kg (110,000 lb). It does not apply to— aircraft airworthiness certified under FAR/EASA-CS Parts 23 as commuter category aeroplanes, and— aircraft airworthiness certified under FAR/EASA-CS Parts 25 but with a maximum ramp mass of > 50 000 kg (110,000 lb), which are covered by ISO 8267？1.Where a family of existing or contemplated aircraft types bridges two mass categories, use a single tow bar attachment fitting interface for all of them, and consider the use of the standard dimensions for the higher mass category, be it part of this document or ISO 8267？1, throughout the family.NOTE As far as practical, this document was defined in order to be compatible with as many existing aircraft types as possible in the mass category concerned.
