RABAT- Morocco’s national carrier Royal Air Maroc (RAM) has suspended a deal to purchase two more Boeing 737 MAX jets after the same model of aircraft crashed in Ethiopia, a source from the airline told Reuters on Thursday.

RAM had planned to receive the two 737 MAX aircraft in June, the source said, adding that two other 737 Max planes in its fleet had been grounded pending the findings of an investigation into the Ethiopian crash in March.

Boeing did not immediately respond to an emailed request for comment.

The U.S. planemaker's top-selling jet was grounded worldwide in March after two fatal crashes in Ethiopia and Indonesia that killed 346 people within five months.

Saudi Arabian airline flyadeal cancelled a $5.9 billion provisional 727 MAX order after the Ethiopian crash and Emirati carrier flydubai has said it could replace MAX aircraft it has ordered with Airbus jets.

Separately, the source said that RAM's fleet of 737 NG is not concerned by inspections that have taken place elsewhere in the world, saying the checks routinely take place on older jets or after a set number of flights.

RAM operates 36 Boeing of the 737 NG planes and only one has required such an inspection and no problems were found.

Southwest Airlines Co and Brazil’s Gol Linhas Aereas have grounded a total of 13 Boeing Co 737 NG airplanes after U.S. regulators ordered urgent inspections last week.
