End Of A Mystery, Debris Of Plane Found After 8 Years

An end has come to the mystery surrounding the Indian Air Force’s An-32 transport aircraft, which had gone missing over the Bay of Bengal, India, in 2016 after debris from a crashed aircraft was detected off the Chennai coast. Twenty-nine personnel were onboard the aircraft which went missing during an operation mission.

The India Air Force on Friday announced that it had located the wreckage of a transport aircraft that went missing nearly eight years ago.

The An-32 transport aircraft, with flight number K-2743, took off from the Tambaran air base in Chennai at 8:30 am on July 22, 2016 and was supposed to land at Port Blair in the Andaman and Nicobar Islands around 11:45 am. The aircraft took off with 29 personnel including, eight civilians 

An Autonomous Utility Vehicle (AUV), developed by the National Institute of Ocean Technology, was launched for deep-sea exploration to locate the missing aircraft at its last known location in the Bay of Bengal. 

The search was carried out at a depth of 3,400 metres using a multi-beam SONAR (Sound and Navigation Ranging), synthetic aperture SONAR and high-resolution photography. The payloads identified debris from a crashed aircraft on the sea bed 310 km off the Chennai coast.

The photographs were analysed and found to conform with the An-32 aircraft. No other aircraft crashed at that site or in that area and the photographs of the debris underpinned the results from the deep-sea search operation. The National Institute of Ocean Technology, which functions under the Ministry of Earth Sciences, believes that the debris possibly belongs to the crashed An-32 aircraft. The findings give closure to families of the personnel who were onboard but the reason behind the crash was never revealed. 

A massive search operation was launched by the Indian Air Force and the Navy to locate the aircraft. Navy’s Dornier aircraft and 11 ships – Sahyadri, Rajput, Ranvijay, Kamorta, Kirch, Karmuk, Kora, Kuthar, Shakti, Jyoti, Ghariyal and Sukanya, were deployed for the search operation.

This was India’s biggest search operation to locate the missing aircraft, which took off in rough weather from Chennai. A preliminary investigation said the aircraft was not carrying essential equipment that would have helped locate it in the event of a crash at sea.

There were reports that the black box of the Indian Air Force’s An-32, which had 29 people onboard, was not fitted with an underwater locator beacon, making a search operation for the wreckage of the aircraft extremely difficult.

The underwater locator beacon is designed to emit an electronic signal at a particular frequency for at least a month after it is automatically activated during a crash and is used on all civilian aircraft.
