What’s really astounding is Boeing on one hand saying they might cancel the -10, whilst at the same time selling that type by the bucket load - must recently at FAB where they racked up a couple hundred orders. Either Boeing are confident the certification will take place before December 20th, or that they can twist the arm of Congress to get an extension, or that they’re still arrogant enough to believe they’re “too big to fail” and that the FAA will be muscled into ensuring the aircraft is certified before the deadline.
Now if memory serves be right, EASA and other regulators were amongst those who agreed to certifying the -8 and -9, on the condition that the -10 would have EICAS and a 3rd AoA sensor, and that those enhancements would be back ported to all other models in the range. So what will happen if the -10 is certified without EICAS and any plans Boeing might have had to develop and implement the system are quietly scuttled?
