Which Should You Buy: Beechcraft Duchess or Piper Seminole?

Bottom line: Choose the Duchess for an affordable twin trainer — a benign, lower-cost multi-engine platform, the value choice for building twin time. Choose the Seminole for the current standard — still in production and the most common multi-engine trainer at flight schools, with strong support. On safety both are light twins with engine-out redundancy and the gentle handling wanted in a trainer, and both reward engine-out proficiency; the difference is era and support, not safety. Value classic, or the flight-school standard.
