1980 Piper navajo chieftain / panther

Description

• Presented for sale is an exceptional 1980 Piper Navajo Chieftain with the Colemill Panther STC conversion — one of the most capable piston twins available at this price point. This aircraft features brand-new 4-blade Hartzell Q-tip propellers with only 2.0 hrs TSMOH, all-new 2024 fuel cells, and a fresh April 2026 annual inspection with no ADs outstanding.
• The Panther conversion adds intercooled engines, winglets, and upgraded nacelles for improved climb, cruise, and single-engine performance over the stock Chieftain. The exterior was freshly painted in 2023 in a striking white base with blue/light blue accent scheme, and the interior features light gray leather club seating with burgundy carpet and walnut cabinetry throughout.
• This is a turn-key, ready-to-fly twin — ideal for owner-operators, island hoppers, charter operations, or anyone stepping up into a capable multi-engine platform.
