Five Remain Hospitalised After Technical Problem On Boeing-made LATAM Flight

Five passengers remained in hospital Tuesday after a technical problem on a LATAM flight from Sydney to Auckland caused the Boeing-made plane to dip violently, the airline and first responders told AFP.

The five still being treated were among 12 passengers on the Boeing 787 Dreamliner initially rushed to hospital in Auckland after flight LA800 experienced an unspecified "technical event" over the Tasman Sea on Monday.

Health New Zealand said all five passengers were all in a stable condition, suffering from a range of injuries. They were being treated at two separate hospitals in Auckland.

The authority's national director Fionnagh Dougan said hospital staff had worked "incredibly hard" to ensure "a seamless transfer of patients" during what she described as a "significant event".

Passengers who had been on the Auckland-bound Boeing 787 Dreamliner told New Zealand media that the plane quickly lost altitude, flinging some towards the ceiling.

"People flew through the air because they weren't wearing their seatbelts" a passenger told public broadcaster RNZ.

"Some people got pretty injured. People were really scared as well," the unidentified man said, his voice shaking.

Brian Jokat, who was on board the flight, said he saw a passenger strike the roof of the plane before falling back down and hitting his ribs on an arm rest.

"He was on the roof of the plane on his back, looking down on me. It was like 'The Exorcist'," Jokat told RNZ, according to the NZ Herald.

A spokesperson for the Chile-based airline said "a technical event during the flight" had "caused a strong movement".

"The plane landed at Auckland Airport as scheduled," the airline said, adding it "deeply regrets any inconvenience and discomfort this situation may have caused".

US manufacturer Boeing has suffered a series of safety issues in recent years, including the fatal Lion Air and Ethiopian Airlines crashes of 737 MAX planes in 2018 and 2019 that killed more than 350 people.

It was not immediately clear what caused the LATAM incident.

The passenger Jokat said that after the plane landed, the pilot came to the back of the cabin.

"I asked him 'what happened?' and he said to me 'I lost my instrumentation briefly and then it just came back all of a sudden'," Jokat said.

"I know he felt really bad for everyone."

"We are working to gather more information about the flight and will provide any support needed by our customer," Boeing said in a statement sent to AFP.

Gerard Campbell of the St John New Zealand ambulance service said medics were first made aware of the problem as the plane descended into New Zealand's largest city.

A phalanx of more than a dozen ambulances and other medical vehicles rushed to the scene to treat the wounded.

"Our ambulance crews assessed and treated approximately 50 patients, with one patient in a serious condition and the remainder in a moderate to minor condition," Campbell said.

"Twelve patients were transported to hospital," he said, after earlier putting the number at 13.

At least three of those treated were cabin crew.

Mobile phone footage posted by the NZ Herald showed concerned crew and passengers attending to one injured woman while flight attendants asked if there was a doctor aboard.

Data from airline tracker FlightAware showed the plane lost altitude about two hours into the three-hour flight.

Boeing is still reeling from a near-catastrophic incident in January when a fuselage panel on a Boeing 737 MAX 9 Alaska Airlines jet blew off mid-flight in the United States.

US regulators earlier this month gave Boeing 90 days to come up with a plan addressing quality control issues, with the Federal Aviation Administration (FAA) chief saying the company must "commit to real and profound improvements".

Last week a Boeing 777 jetliner bound for Japan had to make an emergency landing shortly after takeoff from San Francisco when a wheel fell off and plunged into an airport parking lot, damaging several cars.

Also last week New Zealand's prime minister was forced to take a commercial flight to Australia for high-level meetings because of a last-minute problem with a New Zealand Defence Force Boeing 757 aircraft.

New Zealand's Transport Accident Investigation Commission said it was "aware of (Monday's) reported incident" and was "gathering further information to inform a decision as to whether to open an inquiry".

According to a statement from the Chilean General Directorate of Civil Aeronautics (DGAC), New Zealand will take the lead on investigation of the incident, while the DGAC plans to send its own representative to participate as well.

LATAM said passengers destined for Santiago would now leave New Zealand on Tuesday evening.
