Abstract
An undercarriage for an aircraft has a safety device which fails under a predetermined breaking load to separate a leg member of the undercarriage from a rigid element of the undercarriage, the rigid element remaining on the aircraft. The aircraft has on the frame thereof a front mounting and a rear mounting for mounting the undercarriage and said undercarriage comprises said leg member and said rigid element which is mounted in and extends between said front and rear mountings and forms an axle about the axis of which the leg member of the undercarriage can be pivoted for raising the lowering the undercarriage. Said axle is normally held rigid with said leg member by a front frangible element which fractures under determined stress and a rear frangible element which fractures, under substantially wholly flexion stress, following fracture of the front frangible element, whereby said leg member can separate from the aircraft without coming into contact with elements of the frame of the aircraft when said determined stress is exceeded.
