Question

1. Consider the recent Boeing 737 MAX accidents from Session 6. The accidents are a tragic example of external quality failure , which resulted hundreds of lives lost and severe financial consequences for Boeing and other involved parties. In a few paragraphs (approximately 200-250 words), describe specific actions related to prevention , appraisal , and internal failure detection that could have reduced the probability of the catastrophic external failures that took place.

Answer 1

answer-

Flight ET302 took off from Ethiopian capital Addis Ababa at 08:38 local time (05:38 GMT) on 10 March for a two-hour flight to the Kenyan capital, Nairobi.

The preliminary report into the accident, by Ethiopia's Aircraft Accident Investigation Bureau, said the plane's take-off appeared normal.However, a short time later two sensors that measured the angle of the plane's flight began to record different readingsThis triggered an automated safety system which repeatedly pushed the nose of the plane down - something that was also recorded during the fatal Lion Air flight.The Ethiopian authorities' report suggests the pilots followed steps to disengage the system, but even after manually trying to steady the plane, the system pushed the nose down until the aircraft crashed.

They lacked safety features that could have helped prevent the deadly accidents, which Boeing charges extra for. Both upgrades were related to the plane’s angle of attack sensors, devices that read whether a jet’s nose is pointing up or down relative to oncoming air. One upgrade, called the angle of attack indicator, displayed the sensors’ readings; the other upgrade is a light that is activated if the sensors interfere with each other. These features are considered optional and aren’t required by most airline regulators — but, according to the Times report, they could have helped the planes’ pilots realize something was amiss earlier, and some flight safety experts say they never should have been optional in the first place. “They’re critical, and cost almost nothing for the airlines to install .

If they properly implemented safety measures and training to use those safety measures and inspect the system like twice then all this mishap probably be prevented.
