BEECH D-45 (T-34B)

Everything here is true of every aircraft of the type, not of any one aircraft.

The Beech D-45 is the T-34B Mentor, the US Navy version of the tandem two-seat military primary trainer built on Bonanza wings and landing gear with a new fuselage and a sliding canopy. It differs from the Air Force A45 in detail equipment rather than in substance.

It is bought for the experience: a real military trainer with excellent visibility, aerobatic capability and handling that owners describe as the best thing Beech ever built. The costs are those of a warbird rather than a light aircraft — a surplus airframe with a military maintenance history, and structural inspections including a well-known wing spar airworthiness directive arising from in-flight failures during aerobatics. Verify the spar AD status before anything else; it is the single most important question on any Mentor.

  6. Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories.
