Four persons, including a DGCA official and a pilot were arrested by Delhi Police in connection with the fake flying license scam in New Delhi on March 26, 2011. DGCA had recently grounded 14 pilots who obtained their commercial licences by submitting fake records and document. These pilots whose licenses have been revoked had allegedly not flown the mandatory hours and are alleged to have got fake certificates from a Rajasthan flying training institute. DGCA chief E K Bharat Bhushan said that DGCA would conduct third-party audit of all the 40 flying schools in the country in the wake of cases of forgery behind securing of licences coming to light. Bharat Bhushan, the Director General in DGCA, said essentially there are two types of frauds in regard to fake pilot licenses. One type of fraud related to not passing the Commercial Pilot License (CPL) exam and producing false marksheet to procure the flying license while the other related to flying schools crediting flying hours in certificates which has actually not been undertaken by the persons concerned, he said.
