The Globe and Mail reports in its Tuesday edition that the U.S. Federal Aviation Administration said on Monday it will delay certification of Boeing's long-delayed 737 Max 10 until a newly disclosed software issue is resolved, the latest setback to the plane maker's efforts to bring the largest version of its best-selling jet to market. A Reuters dispatch to The Globe quotes Boeing saying in a statement Saturday that a software issue affecting some of its 737 Max aircraft could prevent pilots from accessing automated flight guidance during a specific landing scenario. The company said it had informed operators and was developing a software update to permanently address the problem. Boeing shares fell 6.3 per cent on concerns about further delays to the Max 10, a key aircraft in Boeing's effort to regain ground lost to Airbus in the lucrative single-aisle market. The FAA said earlier it planned to convene a Corrective Action Review Board to investigate the issue. "We will be delaying the 10 until we're satisfied that we don't have an issue here," FAA Administrator Bryan Bedford told reporters at an event at Reagan Washington National Airport. He declined to estimate the length of the delay.
