For 13 Months Boeing Did Not Reveal The Alert Issue Of 737 MAX To Aviation Body - TNBC USA

Boeing company did not inform the US regulators for more than a year that it implemented an alarm system for indicating pilots about the incompatibility of flight data optional on the 737 MAX  mistakenly instead of standard as on the earlier 737s but also proclaimed that the missing display did not constitute any kind of safety risk. The US aircraft manufacturer has been attempting to chase away the recommendations for weeks that it pushes airlines to pay for the required safety features after it proceeded that an alert implemented to exhibit differences in Angle of Attack readings from two sensors was optional on the 737 MAX.

Misleading data from a sensor is responsible for calculating the angle at which the wing slices through the air – known as the Angle of Attack – is assumed of prompting an imprecise piece of software which forced the plane downward in two recent deadly crashes.

In an announcement, Boeing claimed it only detected once the deliveries of the 737 MAX had started in 2017 that so-called AOA Disagree alert was optional instead of standard as it had pondered but included that was not crucial safety data.

An official of Federation Aviation Administration informed on Sunday that Boeing halted almost 13 months before informing the agency in 2018 November.

Being optional, the alert had been dealt in the same way as a separate alarm system showing raw AOA data, which is hardly used by the commercial pilots and had been an add-on for years.

Boeing informed, “ neither the angle of attack indicator nor the AOA Disagrees alert is necessary for the safe operation of the airplane.”

Boeing said a Safety checking board summoned after a deadly Lion Air crash in Indonesia last October confirmed its preceding conclusion that the alert was not essential for the safe operation of commercial aircraft and could be measured safely in a potential system update.

The Federation Aviation Administration supported the evaluation but condemned Boeing for being slow to disclose the problem.

The Federal Aviation Administration supported the potential assessment but condemned Boeing for being slow to reveal the problem.

Boeing gave an update to the Federal Aviation Administration on the display issue in November, after the Lion Air accident, and a special panel diminished it to be “ low risk” according to a Federal Aviation Administration representative.

He also added, “ however, Boeing’s timely or earlier communication with the operators would have helped to reduce or eliminate possible confusion”.

Boeing allotted the issue of the defected software delivered to the company from an outside source, giving no details.
