Boeing is temporarily halting production of the grounded 737 MAX aircraft.
The US aerospace firm said it would stop making the jet in January.
The decision was widely seen as a humiliating admission that the fleet's
fate lies in the hands of regulators after its own timetable to return
the planes to service dragged by months.
The Federal Aviation Administration (FAA) said last week it would not grant clearance before 2020.
All
versions of the 737 MAX were grounded worldwide in March - days after
an Ethiopian Airlines plane came down outside Addis Ababa, and five
months after a Lion Air flight suffered a similar fate near Indonesia.
A total of 346 people died in the crashes.
Boeing has been working with US regulators to ensure the planes are
safe - with modifications focusing on an anti-stall device called the
Manoeuvring Characteristics Augmentation System (MCAS) in the hope of
returning the 737 MAX to service.
The Federal Aviation Administration (FAA) is not now expected to
grant clearance for US flights until January at the earliest, according
to US officials.
European regulators would need to give their own
approval, at a later date, with pilots also having to undergo
re-training before 737 MAX commercial operations could resume within
European airspace.
A statement from Boeing said: "Safely returning the 737 MAX to service is our top priority.
"We
know that the process of approving the 737 MAX's return to service, and
of determining appropriate training requirements, must be
extraordinarily thorough and robust, to ensure that our regulators,
customers, and the flying public have confidence in the 737 MAX updates.
"As a result of this ongoing evaluation, we have decided to prioritise
the delivery of stored aircraft and temporarily suspend production on
the 737 program beginning next month."
The company said it did not expect any job losses "at this time",
leaving the company under pressure to save costs elsewhere as it
grapples a growing bill - last put at $9bn (£6.8bn).
That sum is expected to rise significantly.
Boeing
has continued to produce 737 MAX jets at around 42 per month, while
also purchasing parts from suppliers at a rate of up to 52 units per
month.
Deliveries have been frozen until regulators approve the
aircraft to fly commercially again, leaving the company scrambling to
find space to store hundreds of planes.
