Its just my theory, just based on other circumstantial evidence, this chap might have been neutralized by the locals, army might have tried to revive him but expired.
Its seems the wing commader Abhi also tried to become a rambo and started the shooting towards the locals.

Indian pilot fired into air before being captured
“A pilot emerged out of the parachute safe and sound,” he told Dawn from Horra’n village by telephone.
Mr Razzaq said he had in the meantime made calls to several youngsters in the village, asking them not to go close to the wreckage until arrival of the army personnel but get hold of the pilot.

The pilot, who was equipped with a pistol, asked the youngsters whether it was India or Pakistan. On this, one of them intelligently responded that it was India.
The pilot, later identified as Wing Commander Abhi Nandan, shouted some slogans and asked which place exactly it was in India.
To this, the same boy responded that it was Qilla’n.
The pilot told them that his “back was broken” and he needed water to drink.
Dawn Exclusive: A time for restraint
Some emotional youth, who could not digest the slogans, shouted Pakistan army zindabad. On this, Abhinandan shot a fire in the air while the boys picked up stones in their hands.
According to Mr Razzaq,
the Indian pilot ran a distance of half a kilometre in backward direction while pointing his pistol towards the boys who were chasing him.
During this brisk movement, he fired some more gunshots in the air to frighten them but to no avail, he said.
Then he jumped into a small pond where he took out some documents and maps from his pockets, some of which he tried to swallow and soaked others in water.
The boys kept on asking him to drop his weapon and in the meanwhile one boy shot at his leg, Mr Razzaq said.
Finally, he came out and said he should not be killed. The boys got hold of him from both arms. Some of them roughed him up, in a fit of rage, while others kept on stopping them.
In the meanwhile,
army personnel arrived there and took him into their custody and saved him from the wrath of the youths, he said.
