How a 50-year-old design came back to haunt Boeing with its troubled 737 Max jet

recovered from the crashed jet to France for analysis, after refusing to hand them over to U.S. authorities. The U.S. National Transportation Safety Board still plans to send investigators to France to help its Bureau of Inquiry and Analysis for Civil Aviation Safety.

The 737 originally was equipped with the Pratt & Whitney JT-8 series jets, which had an inner fan diameter of 49.2 inches. “They looked like cigars, long and skinny,” Moss said. But the LEAP engines required an even bigger change. Boeing redesigned the pylons, the structure that holds the engine to the wing, extending them farther forward and higher up. It gave the needed 17 inches of clearance. The company also put in a higher nose landing gear.

The pilots tried to counteract the nose-down movements by pulling back on the yoke. But even pulling with all their might they could not counteract the forces, according to data in a preliminary accident investigation report.

I’m sure all of the highly qualified engineers who work at the Times reached that conclusion after carefully reviewing materials and design data... right?

Profits over lives everytime. When are people going to stop w brand loyalty crap? Corporations they don't give a damn about you - only profits matter.

How a 50-year design came back to haunt Boeing with its troubled 737 Max jetCompromises required to push forward a more fuel-efficient version of Boeing's 737 — with larger engines and altered aerodynamics — led to the complex flight control software system that is now under investigation in two fatal crashes over the last six months. Why wasn't the fuselage redesigned for the larger engines? Profits? I think it was said that input was provided from a single sensor, its cost cutting like this that endangers life, as an engineer I cannot imagine a safety system tied to a single sensor. your car has 4 sensors , 2 of which are cameras just to make sure you are in your lane This industry should pay damages to everyone harmed. This is what i will call Capitalistic Negligence (saving and making money regardless of life). I believe investors should be held accountable as well. They made it happen with their investments.
