Prime contractor Boeing previously said the test would need to run at least 250 seconds, or more than four minutes
Boeing will pay $2.5 billion to settle a Justice Department investigation and admit that employees misled regulators about the safety of its 737 Max aircraft, which suffered two deadly crashes shortly after entering airline service.
The government and the company said on Jan. 7 that the settlement includes money for the crash victims' families, airline customers and a fine.
The head of Europe's aviation safety agency, EASA, has told the BBC he is "certain" Boeing's 737 Max is now safe to fly.
Executive Director Patrick Ky said his organisation had "left no stone unturned" in its review of the aircraft and its analysis of design changes made by the manufacturer.
The plane was grounded in March 2019.
Boeing dismissed its CEO, Dennis Muilenburg, on Monday morning. He will also leave his position as a member of the board of directors.
The corporation's announcement said Muilenburg's responsibilities would be temporarily assumed by CFO Greg Smith. On January 13, 2020 David Calhoun will take over the CEO post.
The airline's top management has acknowledged that serious safety oversights have been made.
All this was revealed during the testimony of Dennis Muilenburg, US Airline CEO, before the US Parliamentary Committee on Wednesday. He said the company made serious mistakes about a key security system, known as MCAS.
