With no sightings of any debris in the Bay of Bengal, search for the AN-32 aircraft with 29 people on board that went missing on Friday morning, continued on Saturday said an official of Indian Air Force (IAF).
“The search is going on. If there is any substantial development it will be made known,” Wing Commander Anupam Banerjee, Public Relations Officer for IAF told IANS over phone from New Delhi on Saturday, July 23.
A Coast Guard official told IANS that there was sightings of any aircraft debris in the Bay of Bengal by the search team.
Only a catastrophic accident in a “no talk/radio zone” or “dead zone” could destroy an aircraft suddenly, an experienced pilot with the Indian defence forces told IANS late Friday.
Those on board comprised six crew members, 15 personnel from the IAF, army, navy and Coast Guard, and eight civilians who were family members of the personnel.
The aircraft, an upgraded AN-32 belonging to 33 Squadron, took off from Tambaram Air Force Station in Chennai at 8.30 a.m., and was expected to land at Port Blair in the Andaman and Nicobar Islands at 11.30 a.m., officials said, describing it as a “routine sortie”.
According to a report submitted to Defence Minister Manohar Parrikar by Air Force Chief Air Chief Marshal Arup Raha, according to the recorded transcript of Chennai air traffic radar, last pickup was 151 nautical miles east of Chennai, when the aircraft was observed to have carried out a left turn with rapid loss of height from 23,000 feet.
A massive search and rescue operation involving aircraft, helicopters, ships and a submarine was launched immediately to find the plane that went missing around 300 km off Chennai, and will continue through the night.
The last contact with the aircraft was established roughly around 15-20 minutes after the take-off, sources said.
According to IAF, the AN-32 is a twin engine turboprop, medium tactical transport aircraft of Russian origin. It can carry a maximum load of around 6.7 tonne or a 39 paratroopers.
The aircraft’s maximum cruise speed is 530 kmph.
“Planes are designed to fly even during an emergency. There will be reaction time to the pilots facing an emergency to send out messages for help or turn towards safety,” an Indian defence forces pilot told IANS.
According to the pilot, an AN-32 aircraft will not drop down like a stone or vanish into thin air in the case of normal emergency, as there will be reaction time.
“But in the case of a catastrophic threat, the pilots will not have the necessary reaction time,” he said.
An aircraft will not always be on the radar, he noted.
“If the distance to be travelled is around 1,500 km for instance and travel path involves flying over sea then there are chances that the aircraft could not be in the radar from the city of departure after say around 300 km. And it would come into the radar on the other side only when it is around 300 km from its destination,” he said.
“So effectively sometimes there will be a dead zone of 700 km. In smaller aircraft, the pilots switch on to the high frequency for being in touch,” the pilot added.
Coming to the probable cause of its vanishing suddenly, he said: “The possibilities of different catastrophic events happening in the sky cannot be ruled out.”
“For example if an aircraft is caught in a strong thunderstorm, then a plane is as good as a paper caught in the storm.
“The storm will throw the plane like a stone,” he said.
According to him, there have been instances when an airplane that was flying at around 35,000 feet altitude dropped down to 5,000 feet but regained control after that.
The other catastrophic events that can happen to a plane were sudden failure of all the engines; devastasting fire; fuel leakage, jamming of flight controls, loss of flight controls due to fire; power and electrical failure and others.
He said in the best case scenario if the AN-32 had come down gradually then it would have been picked up by some radar or the pilots would have the time to react.
Normally a plane is fuelled taking into account the emergency deviations that may arise – the need to go back to the airport from where it took off or to some other nearby airport in case of an emergency, he added.
The incident comes a year after a Coast Guard Dornier aircraft with three crew members on board for a routine surveillance flight went missing.
The search team found its black box nearly a month later. The skeletal remains and personal belongings of the crew members were recovered from the seabed off the Tamil Nadu coast. (IANS)
Chennai: With Indian Navy’s submarine INS Sandhyak receiving some signals on its sonar, searchers expected some definite information by Sunday evening about an Indian Coast Guard Dornier aircraft, which was reported missing last week, an officer said.
“Submarine INS Sandhyak has started its search in the area where the aircraft is suspected to have fallen,” a Coast Guard officer said.
“By late evening today (Sunday), we should get some information on the missing aircraft,” he added.
An official statement said, the search by the submarine began on Saturday to “confirm transmission of 37.5 khz from Sonar Locator Beacon (SLB) of the missing aircraft, as reported by INS Sandhyak on June 12”.
“The transmission is from around the position where the air traffic control radar lost contact with the aircraft on Monday night (June 8),” the statement added.
“In order to provide further fillip to the search, ICGS Vighraha has been put on the job along with a National Institute of Oceanography (NIO) team, and a black box detector,” said the statement.
The Coast Guard further denied television reports on the aircraft’s location under water.
The aircraft manufacturer would also be roped in to assist in knowing the reason(s) for its disappearance. Help was also sought from National Remote Sensing Centre, Hyderabad.
The Dornier aircraft took off from Chennai airport around 6 p.m. on June 8, for a surveillance sortie, but, went missing on its way back.
The last contact with the aircraft was at 9 p.m. on Monday. Its last known location, as per Trichy radar, was off Karaikal in Puducherry, where it was tracked till 9.23 p.m., 95 nautical miles south of Chennai.
In March, a Dornier-228 of the Indian Navy with three-person crew, went down in the Arabian Sea, off the Goa coast, killing two.
“We are conducting studies on the probable cause for the aircraft’s disappearance,” the official said.
“Unless we get its flight data recorder, or get to see the missing aircraft’s fuselage, we cannot tell anything,” he said. He also said that tests on multi-colour oil sheen found in the sea, also turned negative.
The Coast Guard requested Reliance India Ltd., to extend services of a multi-support vessel with remote-operated underwater vehicle for underwater search.
National Institute of Ocean Technology’s research vessel, Sagar Nidhi, was likely to arrive in the search area on June 14, to augment the search.
The missing Dornier had on board Deputy Commandant, Vidyasagar, as pilot, his co-pilot and Deputy Commandant, Subash Suresh, and navigator/observer, M.K. Soni – all were in their 30s. (IANS)

Chennai: A Dornier aircraft of the Indian Coast Guard has been missing since Monday night, official sources said on Tuesday.
“The aircraft that flew from Chennai and has been over due since 10 p.m. Monday night,” an official said.
Indian Navy and Coast Guard have launched full scale search and rescue operations to look for the aircraft.
A few months backs, an Indian Navy Dornier 228 surveillance aircraft based at INS Hansa, Goa, had also crashed into the Arabian sea during a routine training sortie killing two navy pilots. The ill-fated Dornier aircraft had belonged to the illustrious 310 Naval Air Squadron, codenamed Cobras.

An Indian Navy Dornier surveillance aircraft with three personnel on board crashed into the Arabian Sea off the coast of Goa late on Tuesday, an officer said.
One of them was rescued and two others, including a woman officer whose husband is also in the navy, are missing, the officer said on Wednesday.
The aircraft was from the 301 Naval Air Squadron based at INS Hansa near Dabolim in Goa. It was on a training sortie and communication was lost at 10.02 p.m. on Tuesday, the officer added.
The Indian Navy chief, Admiral Robin Dhowan, has left for Goa, sources in New Delhi said. Nine ships including INS Satpura, INS Betwa, INS Subhadra, INS Koruva, INS Kondul, INS Makar, INS Matanga and ICGS Amal are in the area for search and rescue along with a few naval aircraft, the officer added.
“Commander Nikhil Joshi has been rescued by fishermen in the area. The search is on for the pilot and observer. We have pressed six naval ships and four aircraft to rescue them,” the officer said.
The last known position was 25 nautical miles south-south west off Goa.
