The NVI F.K.33 was an airliner built in the Netherlands in 1925 for use by KLM for night flying. It was a largely conventional high-wing, strut-braced monoplane with seats for ten passengers in an enclosed cabin.
Recognition (WEFT)
| W — Wings | High-mounted, straight |
|---|---|
| E — Engines | 3 × piston, wing-mounted |
| F — Fuselage | 17.5 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Three exposed engines with no nacelles
- Two engines mounted among the wing struts and a third pusher engine on struts above the wing
- High-wing strut-braced monoplane with an enclosed ten-passenger cabin
Look for a high-wing airliner with three bare engines hung among the wing struts and above the wing. None of the engines has a nacelle.
Specifications
- The NVI F.K.33 has a length of 17.5 m (57 ft).
- It has a wingspan of 24.9 m (82 ft).
- Its maximum speed is 190 km/h (118 mph).
- Typical crew: 2.

History
It first flew in June 1925. It was a trimotor, with two engines among the struts bracing the wings and a third mounted pusher-fashion above the wing, none enclosed in nacelles.
Variants
Only one was built. Its owner Baumer-Aero replaced the Armstrong Siddeley Pumas with Junkers L5s and the boarding lights with loudspeakers.
Where you'll see it
KLM operated it for two years on its Amsterdam-London-Paris-Malmo route. It was sold to the German airline Aero, who returned it after two accidents, and then to Baumer-Aero in 1928, which flew it as an advertising machine until 1931. It was requisitioned by the Luftwaffe in 1939 as an instructional airframe.
