The Beech 99 fifteen-seat commuter aircraft is clearly a descendant of the Beech 65 Queen Air, or more precisely the U-21 Ute military aircraft. The Beech 99 retains the rectangular, almost square cabin windows of the U-21, albeit in a stretched fuselage with a much longer nose. This is mated with the turboprop engines of the King Air.
Versions of the Beech 99 differ in engine power, maximum take-off weight and interior outfitting. So there is little to distinguish from the outside. These are the subtypes:
- 99 Airliner
- 99 Executive
- 99A Airliner
- A99A Airliner
- B99 Airliner
- B99 Executive
- C99 Commuter
The Airliner and Commuter are basic passenger versions, while the Executive model has a more luxurious interior.

The Cessna 404 (and to a lesser extent the Reims F406) are a bit smaller than the Beech 99, but have cabin windows with a sharp corner. These windows are rectangular though. Also the nose gear is further aft and the horizontal stabilisers have dihedral.
The Embraer Bandeirante the closest competitor of the Beech 99, being similar in size, purpose and being non pressurised. It however has different cockpit windows, rectangular cabin windows which are rounded at the top, a forward retracting nose gear and single wheel main gear.
The first generation Jetstream is contemporary to the Beech 99. It however has oval cabin windows, a forward retracting double wheel nose gear, single wheels main gears and a cruciform tail. The nacelles are also different.
