US regulator grounds Boeing Max 9 indefinitely as safety checks continue

Washington: The US aviation regulator has extended the grounding of Boeing 737 Max 9 planes indefinitely for new safety checks and announced it will tighten oversight of Boeing itself after a cabin panel broke off a new jet in mid-flight.

As United Airlines and Alaska Airlines cancelled flights through until Tuesday, the Federal Aviation Administration (FAA) said it would require another round of inspections before it would consider putting the jets back in service.

Under more stringent supervision, the regulator will audit the Boeing 737 Max 9 production line and suppliers and consider having an independent entity take over certain aspects of certifying the safety of new aircraft that the FAA previously assigned to Boeing.

The intervention comes after a panel on an Alaska Airlines aircraft, which had been in service for just eight weeks, blew out shortly after take off from Portland, Oregon last Friday.

The FAA said the continued grounding of 171 planes with the same configuration as the one in the Alaska Airlines incident was “for the safety of American travellers.”

The regulator had said on Monday the grounding would be lifted once all planes were inspected before saying more work was needed on planned checks.

On Friday, the FAA said 40 of the planes must be reinspected, then the agency would review the results.

Alaska Airlines and United Airlines, the two US airlines that use the aircraft involved, have had to cancel hundreds of flights in the last week as a widening crisis engulfed the US plane manufacturer.
