Boeing's crisis-hit 737 Max jetliner faces a new potential safety issue
as debris has been found in the fuel tanks of several of the planes.
The head of Boeing's 737 programme has told employees that the discovery was "absolutely unacceptable".
The US plane maker said it discovered so-called "Foreign Object Debris"
left inside the wing fuel tanks of several undelivered 737 Maxs.
A company spokesman told the BBC:
"While conducting maintenance we discovered Foreign Object Debris (FOD) in undelivered 737 Max airplanes currently in storage.
That finding led to a robust internal investigation and immediate corrective actions in our production system."

told the BBC that it was monitoring the plane maker's response to the new issue:
"The FAA is aware that Boeing is conducting a voluntary inspection of undelivered aircraft for Foreign Object Debris (FOD)
as part of the company's ongoing efforts to ensure manufacturing quality.
"The agency increased its surveillance based on initial inspection reports
and will take further action based on the findings," it added.
'suppose a lot more time available for corrective actions,
now that Boeing 737MAX-production is still halted....
