|---|---|
| E — Engines | 3 × piston, wing-mounted |
| F — Fuselage | Passenger cabin seating ten in the fuselage |

WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Conventional biplane with two engines in nacelles on the lower wing
- Third engine mounted on the nose
- Passenger cabin seating ten in the fuselage
Look for a large biplane with a nose engine and two engines on the lower wing.

History
It was a civil transport version of the Keystone LB-5 bomber series, with a third engine in the nose and a cabin for ten.
Variants
The K-47A was the first aircraft rebuilt with a longer fuselage and lower wing. The K-47C was an advertising platform with extended lower wings. The figures here are for the K-47A.
Where you'll see it
Two were built. The first, named American Legion, crashed on 26 April 1927 during a test for an Atlantic attempt, killing Noel Davis and Stanton Wooster. It was rebuilt and later flew for Pan American.
