Piper PA-31-300 Navajo
The PA-31-300 was the original, normally-aspirated version of Piper's Navajo twin, certified in June 1967 with two 300 hp Lycoming IO-540-Ms and two-blade propellers rather than the turbocharged 310 hp engines that defined every later Navajo. Only 14 were built before Piper replaced it after two years with the turbocharged model, which cruised roughly 30 kt faster, climbed higher on one engine and needed less runway. That short production run makes the -300 the rarest Navajo variant, most of the type's commuter and light-cargo service history belonging to its turbocharged successors instead.
