Registration Number 7499
“Came In Downwind To Drag Field”
This aircraft is a Curtiss-Robertson Robin 1, S/N 10 (ATC
40/68). The Curtiss-Robertson Airplane Manufacturing Co.,
Anglum, MO manufactured it on 9/4/28. It was equipped with
a 90 HP Curtiss OX-5 engine, S/N M-2729. It weighed 2,117
pounds. It landed twice at Tucson.
The airplane was sold on 9/7/28 for $3,900 to Harry Sperl
Aero Corp., Los Angeles, CA. We first see it landing at Tucson
on 9/9/1928 piloted by W.F. Shelton. He was westbound from
St. Louis, MO to Los Angeles. He carried no passengers on
what was probably the ferry flight from the factory to the
new owner in California.
The airplane sold again on 10/29/28 to Santa Maria Air Lines,
Inc., Santa Maria, CA, and a year later, on 10/30/29, to the
Hancock Foundation College of Aeronautics in Santa Maria.
It had accumulated 253:42 flight hours as of the date of this
sale, so it was a well-used airplane for its first year of
life. Even so, it endured only one minor accident, at Santa
Maria, on 7/9/30.
It sold again on 5/9/31 to Virgil G. Wilkinson of El Segundo,
CA with OX-5 engine #7296. We next see the airplane landing
at Tucson sometime between 8/24/1931 and 9/4/31 piloted by
S. Saiten with Mrs. Saiten as passenger. They wrote no origin
or destination for their flight, nor their date of arrival
or departure (date of visit interpolated from surrounding
entries in the Register).
It then sold eight more times through 1939, remaining in
the California area and accumulating at least 1155:46 flight
hours. It then moved east on 12/18/39 to its last owner, Carl
L. Washburn of Graham, TX. Its demise began immediately upon
return from Ft. Worth where the airplane was purchased.
It suffered an accident at Graham on 12/18/39 when student
pilot Washburn, “came in downwind to drag field, when
motor cut out. Touched down, attempted to go on, overshot
airport, and settled into a garage near airport.” Pilot
Washburn suffered a broken collar bone and right arm. His
passenger, C.L. Washburn, Jr. suffered a minor head injury.
However, the, “garage was demolished, landing gear washed
out, motor mount broken, prop bent, both wing struts and tips
bent, motor cowl bent, both safety belts broken, instrument
No documents were submitted for registration, since the airplane
crashed on the day of purchase. Registration cancelled 3/8/40.
