TWA Kansas City Overhaul Base

The TWA Kansas City Overhaul Base was Trans World Airlines’ massive aircraft-maintenance facility beside what became Kansas City International Airport. Opened in 1957 at a cost of about $25 million to replace flood-ruined shops across the river, it grew into a 1.7-million-square-foot plant employing more than 6,000 people — at times Kansas City’s single largest employer — where the airline’s entire fleet was overhauled. It was the deepest physical root of Kansas City’s identity as an “airline town,” and it closed in 2010.

Origins — from Fairfax to higher ground

TWA’s overhaul work had moved, in 1945, into the former North American Aviation B-25 bomber plant at Fairfax Airport in Kansas City, Kansas. The Great Flood of 1951 destroyed those Fairfax facilities, and to keep TWA’s maintenance operation in the metro the region landed a new base on higher ground: the Kansas City Overhaul Base opened in 1957 at a cost of $25 million, alongside the new Mid-Continent International Airport — the field that would become Kansas City International.¹²

Scale and work

At its height in the 1960s and 1970s the base was a 1.7-million-square-foot manufacturing and maintenance plant employing more than 6,000 people — “Kansas City’s biggest employer.”¹² It performed heavy overhaul and repair on TWA’s entire fleet (and on other airlines’ aircraft under contract), the deep, skilled maintenance work that kept a transcontinental carrier flying.¹ The base, together with TWA’s headquarters years in the city (1931-1982), is what made Kansas City a genuine airline town.

Decline and closure (2010)

After American Airlines acquired TWA in 2001, the base was steadily downsized and finally closed on September 24, 2010, ending TWA’s — and then American’s — working maintenance presence in Kansas City.¹² The buildings were not demolished; the complex, adjacent to KCI, was reused by other tenants, including Smith Electric Vehicles, Jet Midwest, and Nordic Windpower, with Frontier Airlines leasing hangar space.¹
