Global estimates of aircraft damage incidents have more than doubled over the past ten years, costing airlines $4 billion in 2003 and $10 billion in 2013. Aircraft damage incidents cause the longest and most costly disruptions for individual airlines. The total costs of damaged aircraft, including disruption costs, are usually underestimated and can be much higher. Years-long attempts across the industry to create a standardized model for calculating disruption costs have failed due to the difficulties in identifying and measuring all of the true costs involved.
