Boeing has discovered that some of its stored 737 Max planes have foreign objects in their fuel tanks, CNBC’s Phil LeBeau reported Tuesday.
The company plans to investigate the foreign objects in the tanks, and added that the discovery won’t impact the plane’s return to service at this time.
Boeing also plans to inspect all undelivered 737 Max planes. Boeing produced some 400 Max planes since the grounding until it halted production last month. The company suspended delivery of the new planes after regulators grounded them worldwide in March.
The 737 Max has been grounded since March after two fatal crashes — in Indonesia in October 2018 and in Ethiopia less than five months later — killed all 346 people on the two flights.
