On April 12, Pilot Freeburg, with co-pilot Joe Kimm, departed from St. Paul, Minn., at 3 p.m. en route to Chicago. The plane carried 8 passengers, 6 men and 2 women, besides a load of mail. The plane made its regular stop at Minneapolis at 3:09 p.m. and left at 3:15 p.m. en route to Chicago via Milwaukee. Approximately 45 minutes later, while flying at an altitude of about 2,000 feet in ideal weather, with everything functioning perfectly, the pilot suddenly experienced a terrific jolt. A glance showed that the left outboard motor was vibrating terribly, due to a portion of the propeller having let go. While in the act of cutting the switch, the motor broke loose from its mounting and the pilot, not knowing for the moment what its effect would be on the other motors, cut all the switches and then investigated further. He found that the motor had lodged on the left landing gear struts. Again Freeburg switched on the other two motors and still had an altitude of about 1800 feet. The plane was operating very well considering the additional resistance caused by the motor shell still being in place with a large opening remaining, due to the loss of the motor.
