In 1954 Piper Aircraft Corporation introduced the four-place, retractable gear Apache, developed from the Twin Stinson and the first of the Piper "Indian" executive and business lines that continue to this day. Over 2,000 all-metal Apaches, a departure from the classic tube and fabric Cub and, at $32,000, the least expensive light twin, were built before being upgraded in 1960 to the popular Aztec series.William Davenport bought serial number 14 (unlucky #13 off the line) for Davenport Airlines service between Richmond and Hampton Roads, Virginia. As Aviation Specialists, Inc., Davenport and his Apache offered charter flights and multi-engine instruction, logging more than one million miles. It was believed to be the oldest flying Apache when Davenport flew it to Dulles Airport in 1990.
