A total loss of engine power due to an engine fire that resulted from failure of the turbocharger exhaust clamp, which allowed hot exhaust gases to damage other vital engine components.

The pilot reported that shortly after takeoff he experienced smoke in the cockpit. The pilot reported to air traffic control that he wanted to return to the airport; however, the amount of smoke continued to increase and the engine stopped producing power. The pilot opened the side windows and located a lake below him into which he ditched the airplane. Postaccident examination revealed that the v-band clamp securing the turbocharger exhaust fractured and allowed hot exhaust gas to blow over the accessory section of the engine. The hot exhaust gases caused damage to several components, resulting in a fire and total loss of engine power. The Federal Aviation Administration issued a Special Airworthiness Information Bulletin (SAIB), CE-18-07, recommending detailed inspections of v-band exhaust couplings be performed at 100-hour intervals. The accident occurred on the first flight following a 100-hr inspection that indicated an examination of the exhaust system. The investigation did not determine the total time in service of the clamp or whether a specific examination of the v-band clamp was accomplished.
