Definition

The ADREP damage aircraft taxonomy is a set of terms used by ICAO to categorize an occurrence by the highest level of of damage sustained by any aircraft involved in that occurrence and to allow safety trend analysis on these categories. The ADREP damage aircraft taxonomy is part of the ICAO accident data reporting system (ADREP).

Terms

Destroyed

The damage sustained makes it inadvisable to restore the aircraft to an airworthy condition. This differs from the definition of a hull loss which reads: The aircraft is damaged beyond economical repair. A determination of "hull loss" is thus not only the result of a technical evaluation but may result from economic considerations.
