Aircraft Details- Model SAAB 340B
- Damage Minor
The ICAO definitions around damage are:
- Destroyed : The aircraft is not repairable, or, if repairable, the cost of repairs exceeds 50% of the cost of the aircraft when it was new
- Substantial : Damage or failure that adversely affects the structural strength, performance, or flight characteristics of the aircraft, and which would normally require major repair or replacement of the affected component. Not considered in substantial damage are; engine failure or damage limited to an engine only, bent or dented skin, damage to landing gear (to include wheels and tires), flaps, or wingtips.
- Minor : Damage that neither destroys the aircraft nor causes substantial damage.
I would have thought that damage involving a hole in the fuselage breaching the pressure cabin would be more likely to be classified "Substantial". If the photographs are genuine, this is a wee bit more than "bent or dented skin".
