Hi Gentlemens
How can Pakistan Air Force trust Russian aircraft engines? A lot of people says : Russian RD33 engine had 500 hours lifetime. After you have to change???
Why you dont buy another F-16s? Usa dont sell?

The Initial RD 33 without turbine modifications had a ridiculously low engine life of 350-400 hours before overhaul. In most of the engines which came with the initial batch of fulcrums for the Indian air force , the engine TBO was kept at 200 hrs to reduce a whole bunch of accidents.Most of the contry's operating the MiG 29 (Atleast India and Germany) made modifications to the turbine section to increase this. Currently the overhaul times for the engine is about 650-700 hours , rarely reaches 700 hours though. The problem with the RD 33 was that while it gave enormous power it always used to overheat. That caused turbine failures. The engines manufactured by HAL under license all have the improved turbine section incorporated in them.
