An apparatus and a method for testing oil leakage of a blade pitch control actuator of a ventilator are provided to employ a hydraulic pressure supplying block equipped with two oil injection ports and an O-ring, and a hydraulic pressure supplying pipe equipped with a pressure gauge. A gear part and a controller part are removed from a blade pitch control actuator(S100). A hydraulic pressure supplying block is mounted on a piston shaft instead of the controller part(S200). Oil is supplied to a hydraulic pressure supplying pipe connected to the hydraulic pressure supplying block(S300). A pressure gauge provided in the hydraulic pressure supplying pipe is monitored to check an oil leakage state(S400).
