The eight-seater charter King C90 was on its first airworthiness test profile when it suddenly developed a major technical snag and crashed at an under-construction building in Ghatkopar West on Thursday afternoon. The aircraft was owned by the UP government and after it was involved in an accident some time ago, it was bought by UY Aviation (Pvt) Ltd, a three-year-old company, which rents out aircraft to ferry patients from all over the country, an insider told mid-day. The company had got the King C90 repaired by Indamer Aviation Private Ltd and, on Thursday, it was being taken on its first test flight.

"Around 1.08 pm, the ATC towers at Mumbai and Juhu both lost contact with the pilot and suddenly an SOS alert was sent out by the Air Traffic Control. Finally, it was learnt that the plane had crashed," said Juhu Aerodrome Director Ashok Kumar Verma. Verma said the aircraft took off from the Juhu runway a little after 12.20 pm as per ATC Juhu records. Pilot, Captain Pradeep Rajput, and co-pilot, Maria Zuberi (who had joined UY Aviation barely a month ago), were in constant touch with the Juhu ATC and later with the Mumbai main ATC as it passed through their radar. The charter was barely a mile from Juhu aerodrome, on its way back after completing the test flight, when it crashed. When asked if the aircraft was on a wrong flying line, as usually passenger flights pass through the airway used by the charter, Verma replied in the negative, stating that there was no air space violation and that the charter was on its own scheduled air space."
