I’d start with the exact versions. The PA-32R-300 Lance, PA-32RT-300 Lance II and the different Saratoga models have their own specifications and flight manuals. A comparison based only on the names can miss quite a lot.
For family trips, I’d compare three things:
- The load you actually need to carry. Use each aircraft’s current weight-and-balance report, then account for your passengers, bags and fuel for the intended trip. The number of seats alone won’t answer that question.
- The trip itself. Compare performance using the relevant flight manuals and similar conditions. Consider your usual runway, flight distance and fuel stops, as well as cruise speed.
- The work and spending ahead. Compare engine and propeller history, upcoming maintenance, equipment condition, insurance quotes and any training requirements.
A well-maintained Lance that comfortably meets your usual trip requirements deserves a place on the shortlist. A Saratoga may suit you better, but the reasons should show up in that comparison.
The 1976 Piper Lance PA-32R-300 listed on CollectAirs is one example to work through. Request the current loading documents and maintenance records before drawing conclusions from the advertised figures.
Piper’s technical publications are the starting point for identifying the correct manuals.
Owners of either model: what mattered more in practice than you expected?
