Beechcra's F33A Bonanza had a long production run from 1970 to 1996 and was the final model in the straight-tail Bonanza 33 series. It has a more powerful 285 hp engine than the F33, 300 lbs more useful load and over 900 nm range with optional long-range tanks. Later F33As have the longer cabin and the six-seat capacity of the Bonanza S35 and V35.
