Boeing Chief Executive Officer Dennis Muilenburg on Wednesday reiterated the planemaker was focused on safely returning the MAX aircraft to service.
Malaysia Airlines Bhd is reviewing whether to go ahead with a US$2.75 billion (RM11.5 billion) order to buy 25 of Boeing Co's 737 Max jets in the wake of two fatal crashes that has led to the global grounding of the plane, a person familiar with the matter said.
Sources have told Reuters that the Federal Aviation Administration (FAA) expects to approve the jet's return to service as soon as late June.
But the decision by China, the European Union, and others to ground the MAX before the United States opened an unusual split in the regulatory system, worrying airlines and plane makers.
The procedure, detailed by Boeing in a bulletin to airlines and pilots in November subsequent to the Lion Air crash off Indonesia, involves flipping two switches, and turns-off an automatic control system for the plane's stabilisers.

"We're making clear and steady progress, and that includes the work that we're doing on the airplane update, the software update, working through the certification process with the FAA", he said.
At an IATA meeting for 737 MAX operators in Montreal last week, airline members said they wanted regulators to cooperate closely on the decision for the plane's re-entry to service, de Juniac said.
Boeing has admitted it "fell short" when it failed to implement a safety alert system on the 737 Max.
Concil said IATA's estimate is based on comments from USA carriers that they wouldn't be scheduling commercial flights of the planes through August, and that the FAA hasn't yet provided a timeline on decisions that could allow the planes to resume service.
"We expect continued volatility in the shares until the issues hanging over Boeing move closer to being resolved".
Earlier in the day, Mr Muilenburg had told shareholders Boeing aimed to ramp-up its long-term production rate of the 737 Max to 57 a month after cutting monthly output to 42 planes in response to the groundings.

"I don't see this as an additional material event for us, but it's something that's going to require individual attention customer by customer".
Speaking at an investor conference in NY, he said he hopes all regulators will clear the plane for flying when the FAA does, "but there may be some worldwide authorities that operate on a different schedule".

All 157 people on board were killed.
It is getting fixed, he said, recognizing that "our communication about that was not what it should have been".
