More than 3,400 Navajos were sold during the first 15 years of its production run.

The fuselage was stretched two feet in the latest versions, and the PA-31-350, or Chieftain, became the most popular version with the fly-for-hire trade.

Whether the form of the Navajo followed function or vice versa, it is a successful blend of good looks, good flying characteristics and utility. It can please both the pilot and the passengers, particularly in a corporate configuration.
