The 35A and 36A Learjets are the evolution of the 35 and 36 models, the only major difference being the A models have the Century III wing and a 18,300 lb. gross weight as standard. However, the 35A is still the 8-passenger shorter range version while the 36A is the 6-passenger longer range version. This aircraft can be RVSM certified when Supplemental Type Certificate ST00952SE is complied with.
