How technology may have brought down Ethiopian Airways jet

Published

on

Just hours after an Ethiopian Airlines flight of model, 737 MAX 8 crashed killing all 157 people on board, airlines in a number of countries suspended the use of the aircraft over concerns about its safety.

Flight ET302 crashed Sunday 10March 2019 on its way to Nairobi minutes after it had taken off from Bole International Airport in Addis Ababa Ethiopia.

Pilots reported a technical problem then made a request to turn back to the airport shortly before the deadly clatter.In response to the crash, the Civil Aviation Administration of China ordered Monday that all domestic Boeing 737 MAX 8 jets be grounded by 6 p.m. local time, until the cause of the recent accidents involving the Boeing planes is fully established.

Other countries simply followed suit!

“Given in both air crashes, the aircrafts were newly delivered Boeing 737 MAX 8, and both accidents occurred during the take-off, they share certain similarities,” the Chinese administration said in a statement.

The March-2019 Ethiopian plane crash marks the second accident in five months that a new Boeing aircraft crashed just minutes after takeoff. In October last year, a Lion Air Boeing 737 MAX 8 flight went down over the Java Sea killing all 189 people on board.

While extensive investigations are still underway in both cases, preliminary reports show glaring similarities in the incidents that have prompted caution among some airlines.

In its emergency order, America’s Federal Aviation Administration (FAA) said that they have ‘identified similarities between the crash of an Ethiopian Airlines flight and the Lion Air crash in Indonesia,’ leading the agency to ground all Boeing 737 Max planes.

The Boeing Company is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets, satellites, and missiles worldwide. The company also provides leasing and product support services.

Model 737 MAX is a narrow-body aircraft series designed and produced by Boeing Commercial Airplanes as the fourth generation of the Boeing 737, succeeding the Boeing 737 Next Generation (NG).The new 737 series was launched on August 30, 2011 but made its first flight on January 29, 2016 after getting series of new FAA certifications.

The first MAX 8 was bought and operated by Malindo Air, which placed the aircraft into service soon after the purchase.Boeing engineers introduced two safety technologies which, ideally were supposed to enhance the operability of the plane.

One of the technologies is Augmentation System, designed to reduce mid-air collisions between aircraft as well as to keep the plane at a responsive angle.

The other technology is Traffic Collision Avoidance System (TCAS) that monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air traffic control, and warns pilots of the presence of other transponder-equipped aircraft which may present a threat of mid-air collision (MAC).

“This particular aircraft has something new as far as how the autopilot responds when the aircraft’s nose is too high. It pushes that nose down even when the autopilot is off. And a lot of pilots are not used to that,” said Aviation Investigator David Soucie.

In the case of Indonesian and Ethiopian plane crashes, pilots repeatedly fought to override the Augmentation System but failed to prevail over the technology.

Whereas investigations are still ongoing, preliminary findings suggest that faulty sensors within Augmentation System could have led to wrong responses in the battle between the pilots and the technologies involved.Months before an Ethiopian Airlines crash killed 157 people, American pilots filed a complaint with authorities about perceived safety problems with the same aircraft.

According to USA Today, the two pilots reported their aircraft unexpectedly pitched nose down after they engaged autopilot following departure.It was also reported that another pilot experienced a “temporary level off” triggered by the aircraft automation. The captain of a flight called part of the aircraft’s flight manual “inadequate and almost criminally insufficient.”

“The fact that this airplane requires such jury rigging to fly is a red flag,” that captain – who was not identified by name – wrote in a report to the federal Aviation Safety Reporting System.

The captain said part of the plane’s flight system was “not described in our Flight Manual.”Professional aviators who operated Boeing 737 MAX 8, and logged from April 2018 to December 2018 filed at least 11 reports concerning ‘erroneous’ automation responses.

Both Ethiopia and Indonesian ill-fated planes crashed after experiencing drastic speed fluctuations during ascent, and their pilots tried to return to the ground after takeoff.Aviation experts suspect that MAX 8’s Maneuvering Characteristics Augmentation System, or MCAS, may have caused the jets to make unwanted dives.

In both cases, it’s believed that technology took over the control of the planes from the pilots, and all attempts to take back the control failed – leading to deadly crashes in Ethiopia and Indonesia.

In fact, flight data recovered from the Indonesia crash indicated pilots repeatedly tried to get the plane’s nose up before impact.While responding to Lion Air Boeing 737 MAX 8 crash, Boeing issued a service bulletin warning pilots that erroneous flight data fed into the MCAS could force the aircraft into a dive for up to 10 seconds.

Remains of victims of Ethiopian Airlines crash flown home

Published

on

The remains of thirty-two Kenyans who perished in the tragic Ethiopian Airlines Flight 302 plane crash on March 10, 2019, have been flown to Nairobi today.

An Ethiopian Airline plane carrying the fragments of the deceased landed at the Jomo Kenyatta International Airport on Monday morning.

The remains arrived in specialised caskets and a brief function was held after arrival. Only close family members are to be given the caskets bearing the fragments.

The bodies were severely damaged beyond recognition prompting Ethiopian Airlines to consider DNA analysis to identify their remains.The 32 victims are among 157 people who were killed in the plane crash at Bishoftu town, shortly after taking off to Nairobi.

It is after the International Police through its Incident Response Team revealed on September 12, 2019, that it had successfully identified the 157 passengers who boarded the plane.The team declared the exercise a success saying “six months on after the plane crash, every single victim has been successfully identified.”

“The INTERPOL Incident Response Team (IRT) deployed following the crash of the Ethiopian Airlines plane in March has completed its task, assisting with the successful identification of all victims of the deadly disaster,” the Interpol noted on its website.It noted that the identification exercise was prompted by a request from the airlines’ company.

It stated: “At the request of the Ethiopian authorities, two days after the accident INTERPOL sent an IRT to assist with the operation. The team’s role was to coordinate the international police disaster victim identification (DVI) response and coordinating the antemortem data supplied by member countries.

”Interpol further revealed that the process was aided by a team of 100 DVI experts drawn from 14 countries in Africa, Europe and America. The exercise took 50 days.

Fingerprints and DNA samples were extracted from 48 people, Interpol noted.Also in September, the US-based Boeing planes manufacturer had announced that it had set aside USD2 billion as Financial Assistance Fund for assisting families of victims of the plane crash, which involves the Ethiopian Airlines crash.

The Ethiopian Airlines Flight 302 nosedived just six minutes after leaving Bole International Airport to Jomo Kenyatta International Airport killing all on board.In the incident, Kenya was the worst-hit country losing 32 victims in the crash.

Families who lost loved ones in the ill-fated Ethiopian Airlines plane crash on March 10, 2019 will begin receiving their remains on Monday for burial, the Nation has learnt.

The Nairobi-bound Ethiopian Airlines flight ET-302 crashed in Bishoftu, a few minutes after take-off from Bole International Airport in Addis Ababa.

On Sunday, the family of John Quindos Karanja, who lost five relatives, told the Nation that they will be ferrying the remains ahead of burial on Thursday.

“We thank all Kenyans for the overwhelming emotional, spiritual and financial support towards our family. On Monday we shall be ferrying the remains of our loved ones after they were successfully identified. We plan to have the burial on Thursday, October 17,” said Mr Karanja.

The International Criminal Police Organisation (Interpol) announced in September that it had positively identified all the 149 passengers and eight crew who died in the crash.

Interpol Secretary General Jürgen Stock said the organisation had to rely on accurate DNA sampling from close blood relatives of the victims to make correct identification, which took the group six months.

The Nakuru family’s five members, among them Mr Karanja’s wife Ann Wangui Karanja, daughter Caroline Quinns Karanja and three grandchildren Ryan Njoroge (7), Kellie Wanjiku (5) and Rubi Wangui (9 months) perished in the plane crash.

The family from Kwa Amos village in Kabatini, Bahati in Nakuru County intended to slaughter three goats to celebrate the return.

Mr Karanja’s wife was to bring home her grandchildren who had been living in Canada when the tragedy struck.

A relative of another family from Kipkelion that lost their son – Cosmas Kipng’etich Rogony – also confirmed some members had travelled to Ethiopia to pick his remains.

“The family of the late Rogony travelled and are expected back this week,” said the relative.

Mr Rogony, who until his death was an employee of General Electric’s healthcare division, left behind a one-year-old daughter and a 27-year-old widow Miriam Wanja.

He hailed from Saoset village in Kipkelion West Sub-County.

In March, the families held prayers for their departed relatives but there were no caskets or bodies.
