What caused the failure of Boeing 737 Max?
Two crashes of virtually new Boeing 737 MAXs just over four months apart were each initiated by a single malfunctioning sensor. In both cases, that trigger left the pilots in a deadly struggle against a new flight control system that ultimately forced their jet into a nose dive.
Is Boeing 737 MAX fixed?
FAA approves Boeing’s fix for 737 MAX electrical flaw, clearing the way for return to flight. Boeing won approval from the Federal Aviation Administration late Wednesday for the fix to the jet’s latest electrical problem affecting MAXs built since early 2019, the federal safety agency confirmed.
What enhanced winglets?
Winglets are vertical extensions of wingtips that improve an aircraft’s fuel efficiency and cruising range. By reducing wingtip drag, fuel consumption goes down and range is extended.
What kind of engines are on a Boeing 737?
CFM56-7B ENGINE The CFM56-7B is the exclusive engine for the Boeing Next-Generation single-aisle airliner. In total, over 8,000 CFM56-7B engines are in service on 737 aircraft, making it the most popular engine-aircraft combination in commercial aviation.
Can Boeing remove MCAS?
The Federal Aviation Administration approved Boeing’s request to remove a description of MCAS from the aircraft manual, leaving pilots unaware of the system when the airplane entered service in 2017. The FAA began requiring all MAX pilots to undergo MCAS-related training in flight simulators by 2021.
What is the difference between the 737NG and the 737re?
The 737RE is 5,000 lbs heavier than the 737NG, which means more wear on wheels and brakes, for example. Bair’s example is now reduced by 1\%, for a 4\% COC benefit. Higher ownership costs take their toll. “That 4\% goes down to 2 ½ or 3,” he said. By the time all factors are done, the airplane benefit is down to about 1\%.
Did you know Boeing didn’t really want the 737 MAX?
March 20, 2019, © Leeham News: With nearly 400 Boeing 737 MAXes grounded across the globe, few will remember that Boeing didn’t really want to do the MAX. Officials in 2010-2011 engineered the MAX as a fallback airplane in case its hand was forced by Airbus as it first pondered and then launched the A320neo.
Why was the Boeing 737re dropped?
At one point, “the wind was blowing toward a new airplane.” The 737, he said, was structurally old technology, “with a 707 nose on the same sized body. We could never come up with anything better than a 737 and bring it to life.” So, the engineer said, the 737RE was dropped.
How many times has Boeing looked at re-engining the 737NG?
Boeing looked at re-engining the 737NG two or three times. The company wanted minimal changes, but gaining significant improvements remained elusive. As for the preferred solution, “at that time, they couldn’t make up their mind whether it would be a single-aisle or a twin-aisle,” the engineer said.
