On 28 June 2018, at about 1:15 pm, a Beechcraft C90 King Air aircraft chartered from UY Aviation Pvt Ltd with the registration VT-UPZ crashed at Jagruti Nagar in the suburb of Ghatkopar in Mumbai.^[2] The 12-seater aircraft carried 4 people, including the pilot. All people on board plus one person on the ground were killed.^[3][4][5] A further three people on the ground were seriously injured. ^[1]

As a result of the crash, a fire broke out in the built-up area. Local firefighters and police responded to the accident.^[6][7]

The aircraft had departed from Juhu Aerodrome for a test flight. Five people lost their lives in this accident; 2 pilots, 1 Technician, 1 Aircraft Maintenance Engineer, and 1 civilian.^{[8] [9]}

Investigation[]

The Aircraft Accident Investigation Board released the final investigation report in Dec 2018. The probable cause of the accident as per the report was a stall caused by lack of situational awareness due to spatial disorientation triggered by deteriorating weather, a transition from ILS (IMC) to visual flying (Partial VMC) and unexpected bank owing to differential engine power. The report indicts the Indian DGCA for violation of regulations in granting the Air Operator Permit.

The aircraft VT-UPZ was previously owned by the Uttar Pradesh government. In 2014, the aircraft had an accident^[10] in Allahabad in which there was substantial damage, but the DGCA investigation determined it to be a minor incident. As a result of this report, the certificate of airworthiness was not cancelled. Over the next decade, the aircraft changed ownership and was transported to Mumbai where the repair work was carried out under the supervision of the DGCA.

Capt. Amit Singh FRAeS, an aviation safety and human factors blogger, carried out a detailed independent analysis of the accident and submitted the report to the Secretary, Ministry of Civil Aviation, India.^[11] Capt. Amit Singh has stated that the AAIB investigation was manipulated and did not correctly identify the cause of the accident, and therefore needs an independent investigation by a court of inquiry. The investigation had completely shielded the operator who was granted an Air Operator Permit by the Indian DGCA without having filled the mandatory post of the Chief of Safety.

As per the technical report, the loss of function in both engines during the flight was the most likely cause of the accident.
