Title: Helio U-10 Courier

First flown in 1953, the Helio Courier series of aircraft was specially designed for STOL performance. Approx 500 had been built when production ended in the early 1970’s, including a number for the USAF and US Army as the U-10 series. The type served mainly in South East Asia and achieved some notoriety for also being operated by the CIA. (Who apparently built some examples from spare parts and were later involved in a legal dispute with the manufacturer over it.)

To maximise value, this title contains the USAF Flight Manual for the piston-engined U-10 Courier and also the flight manual for the enlarged turbo-prop powered armed AU-24A. The files have been scanned from the original flight manuals and retain any colour pages.
