In a ten year period to 2000 in Australia, there were 75 reported cases of engine failure in single engined aircraft after takeoff, none of which resulted in fatalaties. In the same period there were 242 reported cases of partial power loss after take off resulting in fatalities in nine cases. The ATSB attribute this considerably worse experience in part to comprehensive coverage of EFATO's in PPL training, but little or none of partial power loss scenarios.
