Dozens of jets had to be taken out of service a week ago because of possible new defects in the ill-fated 737 Max. Instead of a quick solution, further defects have now been found.
On Friday Boeing confirmed that the causal production defects involve components in several areas of the cockpit.
A week ago, the U.S. aircraft manufacturer had warned 16 customers of a potential defect and advised them to suspend the operation of certain versions of the 737 Max until possible defects in the power supply system could be ruled out.
