A retractable, main landing gear for aircraft weighing over a half million pounds comprises four trucks for four oleo struts or three trucks for three oleo struts, all trucks being on a transverse line, both when extended for loading up each oleo strut equally from the instant of touchdown, and when retracted for being positioned contiguous with each other for requiring the least amount of wheel well space. Further, all struts are mounted on trunnions secured to the rear and mid wing spars for providing a minimum of landing gear structural weight.
