The pilot's failure to obtain minimum controllable airspeed during the takeoff climb, which resulted in a loss of aircraft control when the left engine lost partial power. A fatigue failure to an oil tube, which resulted in the partial power loss to the left engine, procedures/directives not followed by the pilot, and the pilot's lack of recent experience and no recurrent training in the type of aircraft were factors.
