What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: while conducting a 135.293/297 proficiency check in Cessna N191C I noticed that the port engine lost partial power on instrument approaches. Power was restored when the mixture was adjusted to a leaner setting. Upon returning to Willow Run, we executed a normal approach and landing. The port engine failed on the landing roll and fuel began to pour from the engine. We observed a mist forming around the port engine and the odor of fuel was predominate. A decision was made to immediately evacuate the aircraft on the taxiway and emergency personnel were notified of our problem. Aircraft fuel line ruptured causing fuel leak.
