Ok, clearly you have misunderstanding about concurrent engineering. It is not making the change during the production stage based on customer's feed back.

The main concept of concurrent engineering is not only making every sub-system contractor to start his part of R&D simultaneously, but bring all other department (i.e procurement, maintenance, factories, airforce, etc) to participate the design work from very beginning. So, these departments can start to design their part of procedure along with designing team, as the result, they can save their time. On the other hand, the design team can receive their feedback immediately and incorporate these into their blueprint before the "final product". So, it can reduce the time-consuming and expensive design change in IOC.

In other words, one of major purpose of concurrent engineering is to minimize the modification after IOC.
If someone blames the modification after IOC for the delay of the project, the concurrent engineering approach didn't work as it is supposed to be in this project.
As has already been discussed extensively, the parts are accurate down to the micrometer, hence interchangable.

You are the same guy who was denying Uyghur enslavement in support of the Chinese government in the China Economy thread.

Mods, Chinese troll alert. Repeating the same misinformation/propaganda over and over again constitutes as trolling.

Even the USA doesn't have that high rate of availability, they were aiming for around 80%.

It has been confirmed that FOC parts were standardized so that there's no issue in production and replacement and also that it has been already achieved months back. Again it's about parts standardization and it's been already achieved so stop repeating the same thing.
Lol 😂
America is the only country who’s Military forces aren’t meant to protect America, they are mostly deployed outside and far away, our Aircrafts are always present in India and not outside with the exception of Farkhor Airbase in Tajikistan where supposedly a MiG-29UPG Squadron is operationally deployed.

So maybe Tejas can achieve ~90% availability. If not AMCA sure will coz this time we are on right track, high quality components made in India or Imported will make our jets among the best!

AMCA’s DSI intake will decrease maintenance thus increasing availability rate.

people talking about AMC
when we can't get full.operational functioning tejas mark one

Don't fall for Chinese propaganda. This guy has posted pro-CCP propaganda before in China economy thread and elsewhere. IAF would never accept a half-baked product, and the FOC Tejas parts are manufactured to micrometer accuracy, so they are interchangable. Parrikar was a patriot who drastically improved SU-30MKI maintenance program as well as Tejas program.
Yup, unlike the chink air force which has to bend whichever way the ccp says ! And accept whatever is shoved down its throat ! So please stop responding to that chink troll

Why Tejas g limit is restricted to 8g when it's wing load is relatively low and air frame is sturdy because of composite materials usage.

air frame is sturdy
Clearly not enough to (safely) pull beyond 8.5g... Airframe had to be as light as possible to meet requirements.
Is it possible to reduce drag and increase g limit of Tejas with existing air frame
Yes. Several. http://delhidefencereview.com/2019/...gn-evolution-of-an-indian-fighter-part-i/amp/

But not to be implemented in Mark1A due to time constraints... Any such changes would requir lengthy flight tests.

I heard that because of composite material usage Tejas is lighter than Gripen aircraft but Gripen max limit 9g. What could be the reason for that

It's not just the weight of the materials, but amount & strength propertoes.

Gripen is heavier & reinforced to take 9g. Tejas is built to be lighter & can take only 8g.

Most of the figures of gripen are just brochure number s
Tejas was flown upto +8.5g but cleared for +8g
Also Tejas was flown with 4.3t payload...but it won't cleared for that
Gripen is just highlighting figures ......
Iaf has evaluated gripen .....flown it
But still they are not interested in it.....some reason s are there
