TheKreider-Reisner XC-31 orFairchild XC-31 was an American single-enginedmonoplane transport aircraft of the 1930s designed and built byKreider-Reisner. It was one of the last fabric-covered aircraft tested by theU.S. Army Air Corps.^[1] Designed as an alternative to the emerging twin-engined transports of the time such as theDouglas DC-2, it was evaluated by the Air Corps atWright Field,Ohio, under the test designationXC-941,^[1] but rejected in favor of all-metal twin-engined designs.

The XC-31 was built with analuminum alloy framework covered by fabric, and featured strut-braced wing and fully retractable landing gear, with the main gear units mounted on small wing-like stubs and retracting inwards. An additional novel feature was the provision of main cargo doors that were parallel with the ground to facilitate loading.

Following evaluation by the USAAC, the XC-31 was transferred toNACA, which used it for icing studies at itsLangley Research Center.^[2]
