Boeing 737 MAX

Lawyers told the BBC that many families were persuaded to sign forms preventing them from taking legal action.

BBC Panorama has discovered that other relatives signed similar agreements after two other crashes, stopping them from suing Boeing in the US courts.

Boeing has declined to comment on the agreements.

All 189 passengers and crew died when the Boeing 737 Max crashed into the sea just 13 minutes after taking off from the Indonesian capital, Jakarta, on 29 October 2018.

Within weeks, relatives were offered compensation by insurance lawyers.

PX CEO, Alan Milne, said the first two will arrive before the end of 2020 and the other two in 2021.

He made the announcement at the Port Moresby Chamber of Commerce & Industry Breakfast event yesterday.

The announcement by the Air Niugini CEO comes in the wake of the Ethiopian Airlines 737 MAX 8 aircraft crash killing all passengers and crew on board.

The incident has seen the grounding of 737 MAX 8 aircrafts by major airline companies around the world.
