what should i do to become an aeronaytical engg after b.e mechanical

I am sorry to say you this but you will have to start the 4 years course afresh again for Aeronautical Engineering to become an Aeronautical Engineer.
So it is not advisable to again study the course of Engineering after you have done so for the course of Mechanical Engineering.
You can do a Post Graduate Diploma for the course of Aeronautics as it is the only option you have.
Otherwise you will need to start afresh to become an Aeronautical Engineer.
