Power Flow exhaust systems gain EASA approval
Until last December, Power Flow exhaust systems were not approved for installation on Easa-registered aircraft unless Power Flow already held EASA validation of the Supplemental Type Certificate (STC) kit specific to that aircraft type. Now, a recent policy change enables owners of Easa-registered aircraft themselves to apply for a specific single-airframe serial number approval by paying a one-time application fee of €239. EASA’S new policy states that if the STC meets seven criteria (with which all of Power Flow’s tuned exhausts comply), it will either issue an approval for that aircraft or refund the customer’s application fee. The approval process requires Power Flow to provide a letter of authorisation specific to a particular aircraft, which it will do at no cost to any aircraft owner interested in the upgrade. Working through its UK authorised dealer, Derby-based Airspeed Aviation, Power Flow has already received approval for two Cessna Cardinal RGS and a Mooney M20J.
Power Flow offers kits for a wide range of GA aircraft from Aviat, Beechcraft, Cessna, Diamond, Grumman, Mooney and Piper. The company claims that its tuned exhausts provide increases of 30-130rpm, 100-250ft/min rate of climb, reduced fuel burn of up to 2.2 US gallons per hour for the same airspeed, and for aircraft equipped with constant speed propellers a 3-7kt increase in cruising speed.
