Four persons, including a DGCA official and a pilot, have been arrested by Delhi Police in connection with the fake flying license scam. With the fresh arrests, a total number of 10 people have been taken into custody in this connection. Acting tough against pilots obtaining their commercial licences by submitting fake records and documents, DGCA had recently grounded 14 pilots. A person is eligible to fly a commercial aircraft only when he or she secures a CPL, which is given out after a person completes 200 hours of flying during the training. However, the 14 pilots whose licenses have been revoked had allegedly not flown the mandatory hours and are alleged to have got fake certificates from a Rajasthan flying training institute.
