Boeing plans to wait three years Broken safety of their 737 Max aircraft determines warnings and speeds up the process only after the first of two fatal accidents involving aircraft.
The company acknowledged that it initially planned to install warning lights in the cabin by 2020 after two main lawmakers revealed the company’s schedule on Friday.
US Representatives Peter Defazio from Oregon and Rick Larsen from Washington wrote from Boeing and the Federal Aviation Administration and asked why the company needed a year to notify safety agents and warned airlines that did not work with Max Jets.
This feature, known as a pitch warning or AoA, warns the pilot when a sensor that measures the aircraft’s nose height might be wrong.
The sensor was damaged during a Lion Air flight in Indonesia in October and flights by Ethiopian Airlines from Addis Ababa in March caused the plane to stop the plane. The pilot could not regain control and the two planes collapsed. In total, 346 people died.
It is not clear whether accidents can be prevented if the cockpit warning is functioning.
A Boeing spokesman said the company initially planned to adjust the cockpit warning due to safety reviews when it began sending a larger Max model for the airline by 2020.
“We cannot refuse AoA’s warnings and take steps to resolve this issue so that they don’t repeat it themselves,” spokesman Gordon Johndroe said.
All Max jets have signals as standard equipment before they resume operation, and the newly built aircraft also have them. Boeing sent around 370 aircraft before being deployed to the world in March.
Both Boeing and the FAA head argue that safety warnings are not critical. Boeing said all of its aircraft, including Max, gave pilots all information about flights – including speed, altitude and engine power – they had to fly safely.
The Pilot Union at American Airlines expressed dissatisfaction with the matter, saying that confidence in Boeing’s cockpit signal was a factor in Union, behind Boeing after Max’s first accident in October.
Jason Goldberg, pilot and spokesman for American Airlines for the association, said the Boeing pilot informed that a warning error sensor could identify even on the ground before taking off.
“This is one of the things that initially convinced us that we would make a statement that we were happy to continue flying on the plane,” he said. – Then it turns out this isn’t true.
Boeing acknowledged in May that in the months following the plane’s debut in 2017, engineers realized that the sensor warning lights only worked when connected to a separate option.
Boeing examined its software called MCAS to use readings from two sensors, not one. If this doesn’t work, it’s easier for pilots to overcome it. It is not clear when the FAA will approve the changes and allow Max to fly again. Regulators in other countries may need more time.
DeFazio and Larsen are Home Committee Officials investigating the FAA disaster and Boeing Regulations. They said that Boeing decided in November 2017 to delay software updates to improve the sensor warning feature in 2020, but shorten the period after the fall of Lion Air.
Larsen asked why Boeing did not consider the problem critical of safety.
On Friday, the FAA’s repeated statement made last month that Boeing had notified the agency office in Seattle of being sent for non-operational signals in November, and the issue of the FAA board’s review, assuming that the problem was “Low Risk”
Last month, the ruling FAA administrator Daniel Elwell told the DeFazio and Larsen Commission that he was not happy that Boeing had waited 13 months to notify the agency of the matter.
“We will ensure that the software anomalies are reported to be faster,” he said.
