Beechcraft King Air B100

Beechcraft · USA · first flew 1975 · transport aircraft

The King Air B100 is the Garrett-engined King Air, using TPE331 turboprops rather than the Pratt & Whitney PT6A fitted to all other King Air variants — the engine cowling shape is the primary recognition feature, as the TPE331 is a straight-flow design with exhaust exiting at the rear of the nacelle, contrasting with the PT6A's reverse-flow front exhaust.

Recognition (WEFT)

W — WingsLow-mounted, tapered
E — Engines2 × turboprop, wing-mounted
F — FuselageIntermediate fuselage length between the 90-series and 200-series — longer than C90/E90 but shorter than 200; window count confirms this
T — TailConventional

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

The Garrett TPE331's exhaust exits at the rear of the nacelle — look for side-mounted exhaust stubs aft of the cowling; all PT6A King Airs exhaust at the front of the nacelle. Against F90: F90 has a T-tail; B100 has a conventional tail. Against King Air 200: 200 is longer with a T-tail and PT6A engines (front exhaust). Conventional tail plus rear-exhaust nacelles is the B100 combination no other King Air shares.

History

The A100 first flew 1969; the B100 followed in 1975 with the TPE331-6 engines giving higher cruise speeds. Approximately 137 B100s were built through 1983 when production ended. The Garrett engine gave better performance at altitude but the PT6A's reputation for reliability and the streamlined 200-series ultimately captured the market. The B100 is a relatively uncommon King Air variant.

Variants

A100 (predecessor, TPE331-3 engines), B100 (TPE331-6, minor refinements). Beechcraft produced no further 100-series after the B100.

Where you'll see it

Business aviation and charter operations worldwide. Some military use (US Army UC-12 series used PT6-powered King Airs, not B100). A moderate number still active in charter and cargo roles in North America.
