AvStrategies is marketing the FAA type certificate (TC) and tooling for a short-lived, single-engine turboprop (SETP) airplane manufactured in the 1970s. The Interceptor 400 was a clean-sheet SETP with a pressurized cabin with seating for three passengers and a pilot. Powered by a 400-shp Honeywell TPE331 engine, the airplane's performance and specs included a cruise speed of 244 ktas, top speed of 300 ktas, 900-nm range, and 24,000-foot ceiling.

Owned by Interceptor Aviation, the package that is offered for sale includes the type certificate (TC), tooling, drawings, and jigs, as well as an actual Interceptor 400 airplane, all of which the seller said has been “carefully stored in obscurity on a farm in Wichita.” In addition, the sale includes a shared TC and tooling for its cousin, the Meyers 200 piston single, more than 100 of which were manufactured and some of which remain airworthy today.

“With FAA certification costs of a clean-sheet design approaching $100 million today, it’s likely the certified platform and tooling will be of interest to existing airplane manufacturers wishing to extend their product lines up- or down-market without the certification risk and cost of starting from scratch,” AvStrategies said of the Interceptor 400.
