Variants and engines
The 1952 Model 50 and the 1953 model used 260-hp Lycoming GO-435s. The C50 (1954) had 275-hp GO-480s. The D50 (1956) had 295 hp and three-blade props. The supercharged E50 (1957) has 340-hp GSO-480s. Supercharged gross weight rose from 7,000 to 7,300 lb by the J50 (1961). The D50E was the last normally aspirated model.
Cabin and handling
The cabin is 54 inches wide with three-across seating. Early models enter over the wing. The D50C (1960) and later have an airstair door. Handling is stable. Roll forces are heavy like a King Air's. Speed changes need trimming only in pitch. There are no cowl flaps; cooling is by augmentor tubes.
What to check before buying
Ask about engine and gearbox history; the TBO is 1,400 hours. Supercharged engines from 1959 to 1963 have Simmonds fuel injection with no mixture controls. Older engines have pressure carburetors. Check for windshield mods (D'Shannon STC, Excalibur swept windshield). Confirm logbook entries for SB 52-2693.

Safety notes
- SB 52-2693 Rev. 2 is mandatory for Models 50, B50 and C50. Inspect the cabin door handle before next flight and after any handle removal.
- Never let the prop drive the engine; this causes gearbox lash and early overhaul. When reducing power, move the props first, then the throttles.
- Use full throttle for no more than one minute, then reduce to 3,100 or 3,200 rpm depending on model.
