Why Is a Partial Loss of Engine Power So Dangerous?

Question: In ground school we are learning about accident reports and the National Transportation Safety Board (NTSB). I was surprised to learn how many accidents begin when the pilot experiences a partial loss of power, which leads to a crash. If you still have some engine power, shouldn’t you be able to make a landing? And how are we supposed to practice this?

Answer: Speaking as someone who spent 15 years writing up NTSB reports, I can say that a partial loss of engine power can catch a pilot by surprise because often it is so subtle. Often there isn’t a dramatic backfire and oil over the windscreen like there is in the movies.
