Pawan Hans has recently started seaplane operation in Andaman islands and they are planning to spread the service fast.Right now they have just 1 one A/c but more are coming in.
In their official statement they have mentioned that the planes are on wet lease, which means they have got foreign pilots to fly those plane's. Also they have mentioned that they will be training indigenous pilots to fly in near.
But i have credible info that the hiring or short listing of pilots for these planes has either already been done or is going to be in a very near future, and the process is an internal one.
