## GM1 ADR-DSN.T.910 Equipment frangibility requirements

(a) Equipment and supports required to be frangible should be designed and constructed so that they should break, distort, or yield in the event that they are accidentally impacted by an [aircraft](https://avioverse.aero/glossary/easa/aircraft). The design materials selected should preclude any tendency for the components, including the electrical conductors, etc., to ‘wrap around’ the colliding aircraft or any part of it.

(b) Frangible structures should be designed to withstand the static and operational wind or jet blast loads with a suitable factor of safety but should break, distort, or yield readily when subjected to the sudden collision forces of a 3 000 kg aircraft airborne and travelling at 140 km/h (75 kt), or moving on the ground at 50 km/h (27 kt).

(c) Guidance on design for [frangibility](https://avioverse.aero/glossary/easa/frangibility) is contained in ICAO Doc 9157, [Aerodrome](https://avioverse.aero/glossary/easa/aerodrome) Design Manual, Part 6, Frangibility.
