Boeing 727-300 Model at Boeing Corporate Archives - circa early 1970's

Boeing studied a final stretch, re-engine, and technology upgrade of the Boeing 727 in the early 1970s. The 727-300 called for an 18 foot stretch of the 727-200 fuselage, a modified wing, new four-wheel main undercarriage trucks, and high bypass Pratt and Whitney JT8D-217 engines. It was designed to carry 220 economy passengers over a 2,000 mile range with 10% better seat costs than the 200. It was originally pitched to Braniff and United, major 727 operators at the time with production scheduled to begin in 1975. An alternative program, the 7N7 competed with the 727-300 at the time. The 7N7 went on to become the 757 and further development of the never-built 727-300 stopped in 1975.
