Boeing jet crashed in Indonesia after key sensor replaced

Boeing jet crashed in Indonesia after key sensor replaced

Authorities are yet to recover the jet's cockpit voice recorder from the sea floor, just northeast of Jakarta, where the plane crashed 13 minutes into its flight.

"We have said there's a technical problem but we also want to know what they were discussing in the cockpit and what they were doing", Soerjanto Tjahjono, chief of Indonesia's NTSC, told reporters on Monday.

The team from Indonesia's National Transportation Safety Committee (KNKT) said that they had arrived at the preliminary conclusions after sifting through details of the flight data recorder (FDR), or black box, which was found in the Java Sea, near Karawang, West Java, last week.

Airlines using the 737 MAX include the Singapore Airlines offshoot SilkAir, Garuda Indonesia and Canada's WestJet, but none had received a bulletin from Boeing.

The Lion Air 737 Max 8 speared into the coastal waters off Java on October 29, just 13 minutes after takeoff.

An Air Canada Boeing 737 MAX 8 (C-FSJH) single-aisle narrow-body jet airliner airborne on short final approach for landing at Vancouver International Airport, Richmond, B.C. on Wednesday, August 29, 2018.

On Monday angry relatives demanded answers from Lion Air founder, Rusdi Kirana, on why the jet was cleared to fly.

The head of Indonesia's Search and Rescue Agency said Sunday that after initially hearing a "ping" from the CVR on Saturday, divers could no longer hear a signal from the device, according to CNN.

As a result of an investigation into the crash the jet manufacturer is said to be preparing a bulletin to be sent to operators of the 737 jets warning about faulty cockpit readings that could cause a dive.

The news was first reported by Bloomberg reported on Tuesday. "These are the things we are trying to find out: what was the damage and how it was fixed".

Lion Air confirmed to CNN that the same aircraft was used on that route, and Indonesian authorities confirmed that the pilot on the flight reported a problem with one of the plane's instruments.

"After 10 minutes in the air the plane dropped as if it was losing power".

According to reports, the initial investigation into the flight pattern of JT610 has suggested that the sensor was producing incorrect data which the flight computer processed to trigger further errors. "If not, technicians in charge must be responsible", he said.

As the 270-square-mile search for debris widened over the weekend, Indonesian authorities broadened a review of Lion Air's operations, including the airline's standard operating procedures and flight-crew qualifications.

Data transmitted from the plane and captured by indicates that the plane continued flying at high speed away from the airport to which they meant to return, which Cox said seemed unusual.

Lion Air is one of Indonesia's youngest airlines but has grown rapidly, flying to dozens of domestic and global destinations. It has been expanding aggressively in South-East Asia, a fast-growing region of more than 600 million people.
