India, Russia to sign pact on spares for Su 30 fleet, availability could go up to 75%

[anant_s]

Like in all complex systems reliability among many other factors depend on
a. Quality of spares
b. Design of system itself

In reliability analysis we hear two things Mean time between Failure (MTBF) (Average time between two failures or outages of a system)and Mean Time to repair (MTTR) (Average time required to bring back system to service or maintenance). These two factors decide the uptime of a system or in simpler words Availability.

Now the quality of maintenance which includes skills of maintainers and quality of spares decides two things. If maintenance is done in proper manner using proper spares, your system will be up for longer improving availability by reducing MTBF.
Similarly the skills and design consideration of maintenance will decide how quickly the maintenance will be done, reducing MTTR.
Both these things go hand in hand to decide Availability and therefore have to be looked holistically.
@MilSpec Sir, could you shed some more light on the topic.

Btw, what is the maintenance time required per hour in the air for the Su-30 MKI.

Hi,

Wasn't su30 being produced under license ?

There are 33000 parts needed to manufacture MKI and India produce 99% of them but then there are ~300-400 critical parts imported from Russia and its about that only.

that is sh1t poor record of just 50%...

Its typical problem with Russian fighter jet. Su30 cost India 40-50 mill$ and this is what you get in terms of quality.
India should ask russia to allow Indian companies to partner with irkut and Su30 system manufacturer.
Importing these parts from Russia is not going to solve the problem, Indian private sector can pretty much deliver higher quality than corrupt russian public sector.

India produced 70% parts but 50% in terms of money. We need to ask Russia to bring up the serviceability to 75% or we should ditch Pak-FA

That's exactly why IAF is signing this pact. Poor serviceability is due to maintenance and unavailability of critical spare parts( which takes upto 12 months to import from Russia due to red tape). With new pact, India will get critical spare parts in less than 30 days and thus improving serviceability by more than 20-25%.

Don't expect Russians to give us everything.... and no we can't ditch Pak-Fa no matter what.

75% for a twin-engined RUSSIAN fighter is not bad at all.....

Infact 75% availability of MKI is very High, look at the range and refuel capability.

Hi,

Any official evidence to back it up ?
