N4228U - 1963 Aircraft Aircraft Registration

Inadequate preflight planning by loading the aircraft over the maximum certificated gross weight, failure to follow procedures and directives by using flaps for takeoff and failing to properly lean the engine for optimum power, and stalling the aircraft. Factors were: Poor judgement by the pilot in operating the aircraft without a current annual inspection, for forging his medical certificate, and failing to obtain and use the proper Owner's Manual for the aircraft. Also, factors were insufficient requirements for the Owner's Manual by the FAA and inadequate aircraft manual information by the manufacturer.
