Collins Proline I began production in the early to mid 1970s and was very common in many business aircraft in the 1970s and early 1980s. The original instruction manuals for most of the units is dated in 1974. Although production of the Proline continued through the 1980s, it can be assumed that a Proline I unit is 20-30 years old on average.
Most of the Collins Proline I components were originally manufactured in the early 1970s. Collins has continued to produce some of the Proline I components by special order over the past 30 years however large scale production stopped many years ago. Most of the Collins Proline I product lines incorporates 1960s and 70s analog technology. Collins has superseded the Proline I product line several times with the Proline II, Proline IV, and Proline 21 lines. As a result, some service parts needed to maintain and repair original Collins Proline I components are no longer available. Therefore, you may experience limited to no warranty available and unreliability for many of the Proline I units.
