Service History

  • Delivered: September 1930
  • Flew with the Boeing School of Aeronautics military flight training program.

Constructed of welded Chrome-Moly steel tubing in truss form. Solid Spruce spars and Dural metal edges were all covered in fabric.

Four prototypes of the YPT-9B were produced for the Army between 1930 and 1931. A conversion of the Model 6-A, this YPT-9B is equipped with a 210 HP Lycoming engine and is one of only two made. As with most trainers, practicality of use, ease of maintenance and the ability to take abuse from the beginner pilot came before beauty.

The civilian 6-L was created as a pilot trainer, but hoped to catch the sportsman pilot. A baggage compartment with an 86 lb. capacity contained two 20 lb. parachutes. A first aid kit and fire extinguisher were standard equipment.

This YPT-9B was used in the Boeing School of Aeronautics aerobatic training. It later found a home as a seed sprayer and crop duster until procured by Yanks in 1987, becoming the third aircraft in the collection.
