Investigations into the crash of the four-seater Cessna 180 aircraft near Bangalore this morning—that killed popular south Indian film actress Soundarya and three others—have revealed that the plane was not endorsed for ferrying passengers on a charter basis. The 32-year-old actor who joined the BJP recently was on her way to attend a party rally in Karimnagar. Her brother Amarnath and the state Hindu Jagran Vedike unit chief convenor Ramesh Kadam were travelling with her. It’s learnt that the Cessna 180 (VTEQU), operated by Bangalore-based Agni Aero Sports and Adventure Club, was registered as a private aircraft and not as a non-scheduled carrier like most other operators involved in elections. Rules set by the Directorate General of Civil Aviation (DGCA) are clear that private aircraft cannot be used for ‘‘hire and reward’’ purposes. Arvind Sharma, the head of Agni Aero Sports, while confirming that the plane was registered as a private aircraft, told The Indian Express that there was no remuneration involved in this flight to Nadirugul airport near Hyderabad. ‘‘We got a non-scheduled operations permit in 1999, but this plane was not endorsed in it,’’ he said and went on to explain, ‘‘My pilot (Joy Phillips, who also died in the crash) received a call from a friend who runs a flying academy in Hyderabad to drop some persons in Nadirugul. Since they also help us, I told my pilot to go ahead. There was no money involved in the operation.’’ Sharma says he had no idea about the identity of the passengers. ‘‘Only when I went to the crash site did someone talk about her fans waiting in large numbers. It is then that I realised that she was an actress.’’ Inquiry team in Bangalore
