Atleast we can replace the Jaguar Aircraft with Tejas Mark II, even if Program delayed, does this spare parts theory apply for Pakistan Mirage III or V aircraft also? their production line also ended? will PAF will also face this maintenance problem? curious to knowWith FBW in place and better engines things are much better with 4th gen jet . And Mirage were extensively upgraded and can be used till 35-40 if spare parts are available till then.
Older airframes gets damaged more need extensive maintenance each time they fly and become a nightmare for operation.
For e.g. Jaguar aircraft is still an excellent design, new frames too, specially for maritime petrol etc . But due to spare shortage engine issue which require expensive upgrade IAF might retire most of them soon.
