Some do. Sr-22 for example.<p>However, often if you’re handling things well, loosing an engine isn’t the end of the world.<p>A lot of accidents happen very close to the ground, at height wear a parachute wouldn’t necessarily be helpful anyway.<p>A parachute, a great solution for some scenarios, but for many, it’s not going to change the outcome. Such examples would be mid collisions, low altitude spiral dives, fires, or anything related to a shortage of oxygen. You also need to consider that during a lot of accidents, other factors, such as weather might be impacting the decision matrix of the pilot, and that might prevent them from using a parachute until it’s too late.<p>The parachutes are also another maintenance item in increasing the cost of running the plane, and generally, the airframe won’t survive the accident, so people are hesitant to deploy them.
