JAKARTA (Reuters) – The pilot of a Lion Air flight from Indonesia’s Bali island on Sunday made a radio alert minutes after take-off due to technical problems, but they were overcome and he pushed on to Jakarta. The same jet crashed on another flight hours later, killing all 189 people on board.

Herson, chief of the airport authority for the Bali-Nusa Tenggara area, told Reuters that after the alert the pilot updated the control tower to say that the plane was flying normally and he would not return to the airport as requested.

“The captain himself was confident enough to fly to Jakarta from Denpasar,” said Herson, who goes by one name, speaking by phone from Bali and referring to the resort island’s airport.

The pilot of another plane that was approaching Bali just after the Lion Air jet had taken off said he was ordered to circle above the airport and listened in to a radio conversation between the Lion Air pilot and air traffic controllers.

“Because of the Pan-Pan call, we were told to hold off, circling the airport in the air,” said the pilot, who declined to be named because he was not authorized to speak to the media.

“The Lion plane requested to return back to Bali five minutes after take-off, but then the pilot said the problem had been resolved and he was going to go ahead to Jakarta.”

Pilots use ‘Pan-Pan’ calls to flag urgent situations. They are a step down from ‘Mayday’, which signals severe distress.

The Denpasar-Jakarta flight landed at the Indonesian capital’s airport at 10:55 p.m. local time on Sunday.

The same Boeing 737 MAX jet took off at 6:20 a.m. the next morning, bound for Bangka island, off Sumatra, and plunged into the sea 13 minutes later. Just before the crash, the pilot had made a request to return to base.

A Lion Air spokesman declined to comment when asked about the alert on the earlier flight, citing the ongoing crash investigation.

The budget airline’s CEO, Edward Sirait, said earlier this week that a technical problem had occurred on the Denpasar-Jakarta flight but it had been resolved “according to procedure”.

Amid media speculation over the airworthiness of the aircraft, the transport minister suspended Lion Air’s technical director and three other officers on Wednesday to facilitate the crash investigation.

The suspended technicians “issued the recommendations for that (final) flight”, the ministry said in a press release. It did not say how many technicians had been suspended.

The country’s second-deadliest air disaster since 1997 has renewed concern about Indonesia’s patchy aviation safety record.

It will also put a spotlight on Boeing’s 737 MAX, which was introduced into commercial service last year and until Monday had an accident-free record. The narrowbody MAX is an update of Boeing’s 737 series, the world’s most produced family of commercial aircraft and one widely considered to have a strong safety record.

ERRATIC FLIGHT

During its earlier flight from Bali on Sunday, JT43, the aircraft flew erratically and its airspeed readings were unreliable, according to an accident investigator and a flight tracking website.

According to data from FlightRadar24, the jet displayed unusual variations in altitude and airspeed in the first several minutes of flight – including an 875-foot drop over 27 seconds when it would normally be ascending – before stabilizing and flying on to Jakarta.

However, the pilots kept the plane at a maximum altitude of 28,000 feet compared with 36,000 feet on the same route earlier in the week.

National Transport Safety Committee (NTSC) deputy chief Haryo Satmiko told reporters on Tuesday there were technical problems on the flight, including unreliable airspeed readings.

Divers on Thursday retrieved a flight data recorder from the plane that lay shattered on the muddy seafloor off the coast of Jakarta. The NTSC said it would examine the device to get a clearer picture of what happened on the flight from Bali on Sunday in addition to the flight that crashed on Monday.

Herson, the airport authority chief in Bali, said the aircraft had encountered a “speed and altimeter” problem but the captain was confident that it was airworthy and pressed on.

“He requested to return to the airport for RTB (return to base) but … they updated and flew to Jakarta. The pilot double-checked to ensure that they could fly,” he said.

Two passengers from Sunday’s flight posted on Instagram, reporting that they had been concerned about problems with the air conditioning system and cabin lighting before the plane left Bali nearly three hours late.

Another passenger on JT43 described, in a talk show broadcast by Indonesia’s TVOne, a turbulent flight during which the seatbelt signs were never turned off.

“When the plane took off, it climbed and then went down. It rose again, and then dropped again violently, shaking,” said Diah Mardani. “Everyone in the plane shouted Allahu Akbar (God is Greatest), Subhanallah (Glory to God). We recited every prayer we knew.”

JAKARTA (Reuters) – Indonesian authorities on Thursday retrieved a flight data recorder from a Lion Air jet that crashed and broke apart in shallow sea near the capital, Jakarta, this week, killing all 189 people on board.

The country’s second-deadliest air disaster since 1997 has prompted renewed concern about Indonesia’s patchy aviation safety record, and the government has said Lion Air will face tougher safety regulation.

Investigations into the world’s first crash of a Boeing Co 737 MAX, introduced into commercial service last year, will be scrutinized by the global aviation industry.

“Hopefully, this can unveil the mystery behind the plane crash,” Indonesia’s transportation safety committee chief Soerjanto Tjahjono told a news conference at Jakarta’s main port after receiving the device, known as a black box.

The data it holds should provide clues to what went wrong with the plane, which had only been in service since August.

It lost contact with ground staff just 13 minutes after taking off early on Monday from Jakarta, on its way to the tin-mining town of Pangkal Pinang.

The pilot had asked to return to base shortly after take-off, and ground control officials had approved the request.

A navy diver told broadcaster Metro TV on board a search vessel his team found the orange-colored box intact in debris on the muddy seafloor.

Indonesia’s transportation safety committee (KNKT) will analyze its data in Jakarta, which could take up to two weeks.

Searchers have yet to find the second black box containing recordings of cockpit conversations. Strong currents have hampered search efforts, complicated by the presence of energy pipelines in the area.

The discovery of the black box may provide some relief to grieving relatives. But hopes are fading of finding a large section of fuselage intact with bodies, easily retrievable, inside.

The commander of the navy divers involved in the search was quoted by the Kompas.com news portal as saying divers had found many bodies. But only one has been identified.

“What is important for us is to get more information about the victims because having their remains back is important for us so we can bury them properly,” said Ade Inyo, whose brother in law was on the flight.

MORE INSPECTIONS, SAFETY REVIEW

The investigation will be carried out with help from Boeing, General Electric and the Federal Aviation Federation, officials have said.

It will also focus on four of Lion Air’s staff including its technical director who were suspended by Indonesia’s transportation ministry on Wednesday amid speculation the aircraft was not airworthy.

“For now, we will focus on two primary causes,” KNKT deputy chief Haryo Satmiko told Reuters, referring to equipment and the people who flew, maintained and managed the aircraft.

The transport ministry suspended for 120 days Lion Air’s maintenance and engineering director, fleet maintenance manager and the release engineer who gave the jet permission to fly on Monday, it said in a press release.

Founded in 1999, the privately owned budget carrier’s aircraft have been involved in at least 15 safety incidents and it has faced tougher international safety restrictions than other Indonesian airlines.

It will now be subjected to more intensive “on-ramp” inspections compared with other airlines, authorities said.

President Joko Widodo has also ordered a review of all regulations relating to flight safety.

Indonesia is one of the world’s fastest-growing aviation markets. Its transportation safety committee investigated 137 serious aviation incidents from 2012 to 2017.

Lion Air said the aircraft that crashed had been airworthy and the pilot and co-pilot had 11,000 hours of flying time between them.

But according to the transport safety committee, the plane had technical problems on its previous flight on Sunday, from the city of Denpasar on the resort island of Bali, including an issue over “unreliable airspeed”.

Lion Air chief executive Edward Sirait has acknowledged reports of technical problems with the aircraft but said maintenance had been carried out “according to procedure” before it was cleared to fly again.

Lion Air’s only other fatal accident was in 2004 when an MD-82 crashed upon landing at Solo City, killing 25 of the 163 people on board, according to the Flight Safety Foundation’s Aviation Safety Network.

In April, the airline announced a firm order to buy 50 Boeing 737 MAX 10 narrowbody jets with a list price of $6.24 billion. It is one of the U.S. planemaker’s largest customers globally and was the first carrier globally to take delivery of the 737 MAX last year.
