The US Federal Aviation Authority (FAA) has said it will not suspend Boeing 737 Max aircraft despite mounting pressure from senators and workers' unions, ONA reports citing BBC.
The FAA said a review showed "no systemic performance issues" and there is no basis for grounding the aircraft.
An Ethiopian Airlines plane crashed on Sunday killing all 157 people on board, in the second fatal accident involving the 737 Max 8 model in five months.
A wave of countries and blocs have banned the plane from their airspace.
On Wednesday Hong Kong, Vietnam and New Zealand joined the list of countries that had banned 737 Max models.
The UK, China, the European Union and Australia had previously done so.
