..And It's A BIG Block

Aero-News learned Monday that Merritt Beach, FL-based Comp Air Inc. has revised its choice for the engine to power its upcoming Comp Air 12 executive turboprop -- deciding on the uprated the Honeywell TPE331-14GR turbine engine, replacing the Lycoming T-53 powerplant originally fitted to the prototype.

Affectionately referred to as a "big block" engine by Comp Air, the powerful Honeywell -14GR has demonstrated an output of 1,815 SHP, with a specific fuel consumption of .497. The Lycoming was rated at 1400 SHP.

The company has also started to set up a support network in anticipation of receiving FAA certification for the aircraft. Executive Aircraft Maintenance of Scottsdale, AZ is Comp Air's main contact for the engine, and will help support the -14GR during and after certification.

Marsh Aviation of Mesa, AZ will also provide engineering assistance in certification of both the engine and airframe.

The all-composite, low-wing, single engine Comp Air 12 executive turboprop kit offers several cabin configurations, depending on what the builder wants or needs. It features an eight-passenger arrangement, that also includes an enclosed head.

 "The Comp Air 12 is a natural extension of our full line of turbine aircraft, which have been growing in size and passenger-carrying capabilities over the past several years," said Comp Air Inc's owner Ron Lueck.

Company executives report the Comp Air 12 kit will sell for $249,000, less avionics, engine and interior. The aircraft shares some features with the Comp Air Jet, including the wing, fuselage and tail assembly.

Comp Air anticipates first flight in late-2006, with certification tests beginning in early 2007. The company will also pursue FAA certification on its upcoming high-wing Comp Air 9... the first time Comp Air has gone after the production aircraft market.
