The Piper Seneca II is a twin-engine light aircraft designed for personal, business and training use. It was certified in 1974 and introduced as the 1975 model, enhancing earlier versions with turbocharged propulsion and improved handling.
Capacity: Typically seats the pilot plus up to five passengers, offering practical space for family, business travel or multi-engine training.
Performance: Equipped with two turbocharged six-cylinder Continental TSIO-360 engines, the Seneca II achieves cruise speeds around 180-190 knots and can reach service ceilings near 25,000 ft.
Range & capability: With a range approaching 800–900 nautical miles, the aircraft is suited for regional to inter-regional missions without frequent stops.
Safety & redundancy: As a twin-engine aircraft with counter-rotating props (reducing critical-engine issues) and retractable gear, it supports more advanced operations than most single-engine models.
Versatility: Suitable for private owners upgrading from single-engine aircraft, charter operations, flight schools offering multi-engine training, or business owners needing dependable regional transport.
If you’re looking to step up from a single‐engine aircraft and want more power, redundancy and capability (especially if you carry multiple passengers or fly longer distances), the Seneca II gives you that bridge. It offers a balance of performance, capacity and operational practicality without moving into the significantly higher cost category of turboprops or jets.
As a twin‐engine aircraft with retractable gear, operating and maintenance costs are higher than most four-seat single-engine aircraft.
Requires correct training and experience (or instructor upgrade) for twin operations and engine‐out performance.
The specific aircraft condition and upgrade state (avionics, maintenance history, engine hours) will significantly affect value and operational cost.
Payload versus fuel and passengers must be managed carefully, especially on hot or high‐elevation airports.
