Airframe life is fixable.
If the PAF is serious about a LIFT the F-7PG is a very good option....With engine upgrade the range and aircraft performance will be revamped.
F-7PG is a robust aircraft and can handle a beating by novice.
What PAC needs to do is to swap with a better engine and upgrade the cockpit.
This is not only a cost effective solution for LIFT but also a very respectable Red air for PAF.
Red air and F-7PG go hand in hand, this fighter will be a Pain in the behind to beat-- small nimble fast and agile.
Airframe life is not any uses decision it’s Oem supported decision and Chinese did not supported Pac , Pac decided to come up with their own extension W/o Oem for 100 hours or so but is not recommended it’s was just a non availability of $$ per paf history book and that too for dual seaters only
Lastly new engine cost kore than the airframe with no life
Lockheed did extend f-16 life not one of the airforces or someone else , Pac as Oem for Mashaq extended life from 8000 to 12000 and than 16000 and finally 18000 now all mashaq are cleared for 18000 hours airframe life
Mirage case a Spanish company supported by Oem did analysis for paf to confirm mirage Fusalage for 8000 hours and wings for 2250 hours life
