- 4 - hydromatic, full-feathering propellers. The aircraft was currently certificated as airworthy to carry 21 passengers and 4 crew members at a standard weight of 24,546 pounds and a provisional weight of 25,346 pounds with de-icing equipment.

The aircraft had been operated a total of 3,834 hours 22 minutes. Major overhauls were required by the air carrier operating certificate after every 650 hours of operation, but the airplane had been flown only 424 hours since its last major overhaul. The engines and propeller had likewise been operated considerably less than the specified overhaul periods. PCA records indicate that the airplane had been properly maintained. It thus appears from the evidence that the aircraft was in an airworthy condition when it was dispatched on March 2, 1942, for the flight to Detroit.

The evidence indicates that the aircraft and all its equipment functioned properly throughout the flight, and that it was loaded below the standard weight and within the prescribed center-of-gravity limits at the time of the accident.
