Over 50 Boeing passenger jets grounded worldwide due to ‘wing-related cracks’

Over 50 Boeing passenger aircraft were grounded around the world after the discovery of ‘wing-related cracks’, world’ biggest plane maker confirmed today.

It’s the US aviation giant’s 737NG (Next Generation) model that is now under scrutiny. The plane is a precursor to the infamous Boeing 737 MAX, which killed 346 people in two crashes in Indonesia and Ethiopia, and has been grounded since March.

A Boeing spokesperson said that some 1,000 planes worldwide had “reached the inspection threshold.” The problem these inspections zeroed in on was the so-called ‘pickle fork’ – a part of the plane that connects the fuselage to the wing.

The US aviation authority this month ordered checks of Boeing 737NG planes that had made over 30,000 flights.

Meanwhile, the plane maker’s CEO was testifying before a US House panel on Wednesday, where he said the company had made some mistakes on the key safety system known as MCAS.

“I am responsible. These two accidents happened on my watch. I feel responsible to see this through,” Dennis Muilenburg admitted, refusing to step down.

Two deadly crashes in less than six months involving Boeing’s newest 737 MAX 8 airplane put the credibility of the manufacturer in jeopardy. The fatal Ethiopian Airlines accident claimed 157 lives in March, and was followed by a similar crash in Indonesia, which killed all 189 people on board in October.
