D’Shannon Aviation has developed new engine baffle systems for Beechcraft Barons and Bonanzas, designed to eliminate any loss of cooling air through the cowling and maximize engine cooling. The new Baffle Cooling Kits consist of engine-mounted aluminum baffles with high tear-strength silicone, and these mate with composite inserts attached to the upper cowling. During development the new baffles were flight-tested in ambient temperatures as high as 100 degrees F. The new kits fit Continental IO-550, IO-520 and IO-470 engines on the Bonanza and Baron.

RAYTHEON BEECH KING AIR 300, NEAR TULSA, OKLA., JUNE 22, 2002–There were no reported injuries as a result of N224CR’s in-flight separation of a portion of the left-engine cowling during cruise flight. The twin turboprop was owned by Ponca City Transportation of Ponca City, Okla., and operated by Flight Concepts of Tulsa, Okla., under Part 91.
Dassault Falcon 2000, Stilesville, Ind., April 14, 2006–The NTSB was unable to determine why the left engine cowling of Falcon N722JB detached and hit the lower spar of the horizontal stabilizer in cruise at FL250. The cowling, which was never located, also damaged the left engine primary fuel line.
As unveilings go, it wasn’t in the quite same category as Janet Jackson’s “wardrobe malfunction.” But on the other hand, displaying a new engine cowling isn’t going to get the FCC coming down on you, and the folks at DynCorp International in Fort Worth and Temsco Helicopters of Ketchikan, Alaska, seemed happy with it.
Dassault Falcon 2000, Stilesville, Ind., April 14, 2006–The Falcon 2000, N722JB, was at FL250 when the left engine cowling separated from the engine and hit the horizontal stabilizer. The crew heard a loud noise and diverted to Stilesville, where they landed without incident. The airplane was substantially damaged, but the pilot and copilot, the only occupants, were not injured.
