An American-registered, Swiss-flown Siai-Marchetti, was recently converted with the addition of a new Chabord exhaust system, which changed the plane’s Airworthiness Certificate from S205-18R to -20R.
Owner/pilot Ariel Beresniak worked with Alain Chabord and the FAA to gain approval for the conversion, which saves some 40% of the weight, compared to the stock system, and also produces less noise, even while allowing the engine to produce additional power, according to company officials, who note the Lycoming IO-360A1A is running at 200 hp.
“I needed to replace the oroiginal exhaust system,” said Beresniak, “and the original was no longer available. The Chabord system was very easy to install, it weighs less, it is quieter, it produces more power… and it looks good.”
The Inconel system includes everything from exhaust gasket to exhaust tip, and was developed in the Chabord shop, where engineers also produce exhaust systems for Le Mans and Formula 1 race teams, as well as special-order custom systems for high-performance prototypes in automotive, motorcycle, and aerobatic competitions, including the Red Bull championship.
“We wanted to demonstrate exceptional performance, quieter operation, and customer satisfaction before we announced this exhaust system,” said Chabord,. “We will be showing this system, as well as systems for other popular aircraft applications, including Van’s RV, Cessna C-150 and -152, and the Rotax 912 series, at AirVenture Oshkosh.”
