This is so vague as to be useless. What does "could reach $250M" mean? Like, that's the largest anyone ever paid? And without a citation, there's no way to find clarity. |

A hull loss is an aviation accident that catastrophically damages the aircraft beyond economical repair,[2] resulting in a total loss. The term also applies to situations in which the aircraft is missing, the search for their wreckage is terminated or when the wreckage is logistically inaccessible.[3]
The metric of "Hull losses per 100,000 flight departures" has been used throughout the aviation industry to measure the relative risk of a given flight or aircraft.[2] From 1959 to 2006, the first part of the mainstream jet aircraft era, 384 of 835 hull losses, or 46%, were nonfatal.[4] Airlines typically have insurance to cover hull loss on a twelve-month basis.
Constructive hull loss takes into account other incidental expenses beyond repair, such as salvage, logistical costs of repairing non-airworthy aircraft within the confines of the incident site, and recertifying the aircraft, among other factors. Insurance policies covering any asset that is subject to depreciation typically pay the insured a formulaic used item value, so the property will often be a write-off as full repairs minus this sum resemble a cost of a new replacement.[jargon]
