Commuter Airlines

Broome County Aviation, Inc, took over as the fixed-base operator (FBO) at Greater Binghamton Airport, New York in 1957, selling aviation fuel, operating a flight school and air charter service. In 1965 they began FAR part 135 scheduled flights with a Piper Aztec between Binghamton, NY and Washington National Airport D.C. operating as Commuter Airlines (CA Inc).

During the next two decades the airline side of the business expanded, increasing the number of destinations served to include White Plains, LaGuardia and JFK in New York City, Newark, Boston, Wilkes Barre/Scranton, and Allentown Pennsylvania, and others.

Commuter Aircraft Manufacturing Corp

The Dumod Corporation was one of a number of companies that specialised in upgrading Beech 18s, primarily featuring a tricycle undercarriage replacement for the original tailwheel design. Their most ambitious project was the Dumod Liner, and the manufacturing rights for this conversion were purchased by Winston on behalf of BCA/Commuter Airlines. The Dumod Liner had a stretched fuselage allowing 15 seats, a nose wheel/tricycle undercarriage, and a triple tail similar to the Lockheed Constellation. Initially five conversions were planned, but only three were completed, and all three of this unique design were operated by Commuter Airlines.

Fleet

The company began with a single Piper Aztec and over the years added Piper PA-31 Navajo/ Navajo Chieftains, Beechcraft Model 18s and of course the three Dumod Liners, before expanding with Swearingen Metroliners from 1973. In 1978, with the advent of deregulation, Commuter Airlines increased capacity by purchasing five Convair 580s from Allegheny/(USAir).

Accidents and incidents

On 22 March 1970, Commuter Airlines Flight 502 from Binghampton to Washington D.C., operated by Beech 18 (Dumod Liner) N497DM, crashed after a rejected take-off from Binghamton-Broome County Airport killing the Captain and two passengers. The co-pilot and seven remaining passengers survived.

After taking off in snow conditions, the aircraft became airborne, but was difficult to control even after the landing gear was raised. The captain elected to reject the take-off, and made a smooth wheels-up landing. The aircraft slid the remaining length of the runway, over an embankment, and into approach light structures, where it subsequently caught fire and was written off.

The NTSB report determined the probable cause of the accident was the attempt of the pilot-in command to take off with snow adhering to the airfoil surfaces, causing a degradation of aircraft performance and loss of control following lift-off.
