The Beech Musketeer series is also here with an interesting twist. The original airplane, the 23, had a 160 Lycoming and was built in 1963. A lot of pilots thought the airplane was a poor copy of a Cherokee. So, in 1964 Beech remedied that with the A23. It is the only airplane in this category, and of the ages we are talking about, that was built with a fuel-injected engine, a Continental IO-346-A that develops 165 horsepower. The engine is, in fact, two-thirds of an IO-520, which came to the Bonanza S35 the year before.
