What is ISO 8267-2 - Interface requirements about ?
ISO 8267-2 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.
ISO 8267-2 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.
ISO 8267-2 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 ISO 8267-2, where deemed appropriate in order to facilitate the operation of such aircraft types at airports.
ISO 8267-2 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).
Note: ISO 8267-2 does not apply to:
- Aircraft airworthiness certified under FAR/EASA-CS Parts 23 as commuter category airplanes
- 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
Note: As far as practical, ISO 8267-2 was defined in order to be compatible with as many existing aircraft types as possible in the mass category concerned.
Who is ISO 8267-2 - Interface requirements for ?
ISO 8267-2 on interface requirements is useful for:
- Civil transport aircraft manufacturers
- Aircraft manufacturers
- Aerospace and defence industries
- Design engineers of aircraft
- Quality control personnel for aircraft
Why should you use ISO 8267-2 - Interface requirements ?
The aim of ISO 8267-2 is to standardize regional aircraft tow bar attachment fittings according to aircraft mass category (which determines tow bar forces) so that one tow bar can be used for all aircraft within that mass category.
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, to assist operators and airport handling companies in reducing the number of different tow bar types used.
ISO 8267-2 provides you with requirements such as fitting location and configuration, towing loads, aircraft mass categories, dimensions, and clearances, tow bar fit to assess and consistently maintain quality.
