Boeing says it found debris in fuel tanks on grounded 737 Max jets

Boeing announced it has ordered inspections of its grounded 737 Max series jets, after it found foreign objects in the fuel tanks of some of the aircraft.
The company said it immediately made corrections to its system to prevent a repeat of the problem.  Mark Jenks, Boeing’s general manager, called the debris “absolutely unacceptable” in a memo to employees who worked on the series.
Last year, the aviation giant grounded its 737 Max planes, after deadly crashes that resulted in the deaths of 346 people, were linked to faulty software. Because of this, the planes with debris in the fuel tanks were in storage.
Engineers say that foreign objects, such as metal shavings and tools left in the fuel tanks can raise the risk of electrical short-circuiting and fires.
The Boeing 737 crisis has crippled the company’s earnings, with the aircraft maker posting a net loss of $636 million last year, compared to some $10.5 billion in profits during the year before. The company said it is optimistic that that the Federal Aviation Administration will certify the plane to fly again this summer.
