Hull loss

A hull loss is an aviation accident that damages the aircraft beyond economical repair,[2] resulting in a total loss. The term also applies to situations in which the aircraft are missing, the search for their wreckage is terminated or when the wreckage is completely inaccessible.[3]

"Hull losses per 100,000 flight departures" has been a long-used statistical criterion.[2] From 1959 to 2006, throughout almost the entire jet aircraft era, 384 of 835 hull losses, or 46%, were nonfatal.[4] Airlines typically buy insurance to cover hull loss on a twelve-month basis. Before the September 11 attacks in 2001, the typical insurance amount for hull loss could reach $250 million, but since then demands for higher liability have increased.

Constructive hull loss factors other incidental expenses beyond repair, such as salvage, logistical costs of repairing the non-airworthy aircraft within the confines of the incident site, recertifying the aircraft, etc. Insurance policies covering any asset that is subject to depreciation, typically pay the insured a fraction of the cost of replacing the property, so that a loss may be deemed to be total although some residual value remains.
