Title: Interstate L-6 Cadet 

The first aircraft produced by the Interstate Co was the S1B Cadet, a two-seat tandem liaison aircraft. Around 320 had been built as civil aircraft when the USA entered WW2 and production was turned over to military variants. The first military evaluation model was designated XO-63, the last aircraft to wear an “O” (for observation) designation. The USAAF ordered 250 production examples as the L-6. However the aircraft never saw operational service and it was the liaison aircraft with the fewest number procured.

This title contains the USAAF pilot flight manual for the L-6 along with the Erection and Maintenance Manual. The files have been scanned from the original flight manuals and retain any colour pages.
