Hello dear,
Yes, you may.
Hindustan Aerospace & Engineering is an institution situated in Pune that offers aircraft maintenance courses. These will not fetch you either B.Tech or B.E degrees since courses offered are not approved by AICTE. But, since these are approved by DGCA, you get employment opportunities.
