Title: Fairchild C-123 Provider

The C-123 was designed by Chase Aircraft Corp, initially as a large assault glider. Two prototype XCG-20 gliders were built, then converted to powered configuration, one with two R2800 radial engines and one with four J47 jet engines. The former proved successful and a large production contract was ordered by the USAF. For political reasons the contract was put up for bid as the C-123B and awarded to Fairchild Aircraft.

The aircraft proved rugged and reliable, and a number of upgrades were developed over the years involving improved undercarriage and brakes, auxiliary jet engines, etc. The aircraft was used extensively in Vietnam, including the controversial “Agent Orange” defoliation programme.

This title contains flight manuals for two variants of the C-123. The files have been scanned from the original flight manuals and retain any colour pages.
