risk: aircraft flight hours and departures. Airclaims Limited defines a total loss as an aircraft that has been destroyed or for which the estimated repair costs rendered the aircraft a total loss under the terms of the insurance contract. (Airclaims Limited notes that some airplanes that became total losses were repaired and returned to service.) Any total loss that resulted from a deliberate violent act was eliminated from the Board's comparison. The results of the comparison are shown in table 3.
