@rahulsarma: There are 7 Seneca 200/200T/220T in India
Thing is some of them have their CofA lapsed and some of them will be lapsed by July except Falcon's 200 which is I guess still in process of getting its CofA.These being flight schools I hope they renew it, if not, then God help us.
Please do check DGCA's homepage right hand side where you can know CofA entry by registration and you can find the registration by clicking on 'Know your a/c before you fly'
