Registration Number 7246

A Neglected Western Aircraft

This aircraft is a Kreider-Reisner C-2 Challenger, S/N 198 (ATC 19). The Kreider-Reisner Aircraft Co., Hagerstown, MD manufactured it on August 1, 1928. It was equipped with a 90 HP Curtiss OX-5 engine, S/N M-4736. It weighed 2,000 pounds.

The airplane was sold for $3,335 (less 15%) on August 29, 1928 to Phillips Flying Service, Inc. of Seattle, WA, Don S. Phillips, President.

We find the month-old airplane in Tucson, piloted by Phillips, on September 9, 1928. He was inbound from Lordsburg, NM enroute to Los Angeles. He and 7246 were competing in the 1928 National Air Races. A photograph of 7426 on the ground at Los Angeles, CA after the Race is at the link. 7426 is the second airplane back.

In Phillips’ hands, the airplane logged 132 flight hours as of November 17, 1928. On May 7, 1929 it was involved in an accident at Almira, WA. The reason, “severe storm, plane struck pole after landing.” There was damage to the prop and left wings. Pilot Phillips and passenger Eddie Brown were uninjured.

On July 10, 1929 the mortgage was foreclosed and the airplane was sold to Paul W. Schubert of Seattle, WA. New left wings were installed and the airplane was inspected and approved for registration on July 11, 1929.

Two months later, on September 7, 1929, the airplane was grounded for being unairworthy. The right lower wing was badly warped and the fabric, according to the inspector, was, “terrible.” Over the next two years it was repaired, inspected and disapproved for flight another couple of times. On November 7, 1931 it was sold to W.M. Smith and Clifford S. Thomas of Everett, WA. It was “rebuilt” as a Challenger KR-31 as of December, 1932 and July, 1933.

It sold twice more until, finally, on May 23, 1935, its final owner Murrel E. Gray of Payette, ID failed to submit an acceptable bill of sale and did not apply for registration. The registration was cancelled upon expiration on August 1, 1935. No further information.
