In reality, about three quarters of all aircraft accidents result in minor or no injury to the pilot or passengers. A great deal depends on the type of accident and how the aircraft was handled. Just as with automobiles, certain types of incidents are more serious. A head-on collision in a car, although not common, is usually serious. In aviation, weather-related accidents are usually serious, and we'll discuss them in detail momentarily.
Fender benders are much more likely.
The aviation equivalent to the fender bender is the landing accident. A typical scenario will be a windy day where the wind may not be blowing right down the runway. The crosswind will cause the aircraft to drift off the side of the runway if the pilot doesn't make a correction. Landing in the rough will generally cause some damage to the aircraft. These kinds of accidents are easily prevented by developing and maintaining proficiency in handling crosswinds and by choosing runways more aligned with the prevailing winds.
