Boeing 737 plane crash: Findings out on Ethiopian Airlines disaster

When the Boeing 737 MAX achieves speeds greater than 230 knots (265mph or 425kph), with its flaps retracted, pilots would potentially have to intervene using a wheel on the center console as opposed to an electric thumb switch to which they might be accustomed.

"[Boeing officials] have to discuss the matter internally", said Garuda Indonesia president director Ari Askhara in Nusa Dua, Bali, on Friday, as reported by Antara.

The Maneuvering Characteristics Augmentation System (MCAS), the flight stabilization system that prevents a Boeing 737 MAX aircraft from stalling, was activated shortly before the crash of Ethiopian Airlines, according to the preliminary analysis of the flight recorders.

According to Ethiopian Airlines CEO Tewolde GebreMariam, pilots transitioning to the Boeing 737 Max 8 aircraft from older 737 models were required only to undertake a short computer-based training program prescribed by Boeing and approved by the FAA.

In a briefing to reporters, Boeing said that the upgrades were not an admission that the system had caused the crashes.

He vowed that Garuda Indonesia did not plan to shift its order to another aircraft maker but ask Boeing to offer the airline other types of aircraft.

The family of Jackson Musoni, a Rwandan who was among the casualties of the March 10 Ethiopian Airlines crash has sued Boeing, the manufacturers of the plane.

The reported findings come from a preliminary report that's required by the investigating authority to be produced within 30 days of an incident. Filed in a Chicago court, it claims that Boeing had defectively designed the automated flight control system and had failed to warn the public, airlines and pilots of the airplane's allegedly erroneous sensors.

"Boeing.is working with the authorities to evaluate new information as it becomes available", it said, adding all inquiries about the ongoing accident investigation must be directed to the investigating authorities.

Both crashes killed a combined 346 people and are being investigated by teams of global experts led by the countries where the flights originated.

Sinnett said making the software updates to each plane will take about an hour and will begin immediately. Boeing's 737 Max 10 has not yet entered service and it's unclear whether it will also receive the updates.

Morningstar analyst Chris Higgins on Thursday reduced his estimate for how long the groundings would last to two months from three, based on details presented by Boeing of its proposed fix to the MCAS software.

The investigation into the March crash, which is being led by the Ethiopian Transport Ministry, is still in progress.
