Boeing feels the pressure

Ethiopia claims parallels between its crash and one in Indonesia

-

THE world’s biggest plane-manufactur­er faced escalating pressure yesterday after Ethiopia pointed to parallels between its crash and one in Indonesia, placing the focus on the safety of software installed in Boeing 737 MAX planes.

The Ethiopian Airlines disaster eight days ago killed 157 people, grounded Boeing’s marquee MAX fleet worldwide, and sparked a highstakes inquiry for the shaken aviation industry.

Ethiopian Airlines, whose reputation also hinges on the investigat­ion, said at the weekend that initial analysis of the black boxes showed “clear similariti­es” with a Lion Air flight from Jakarta in October that crashed, killing 189 people. Both planes were MAX 8s and crashed minutes after take-off with the pilots reporting flight control problems.

Under scrutiny is a new automated system in the MAX model that guides the nose lower to avoid stalling.

Lawmakers and safety experts are asking how thoroughly regulators vetted the system and how well pilots around the world were trained for it when their airlines bought new planes.

Ethiopian Transport Ministry spokespers­on Muse Yiheyis said on Sunday that data recovered from the black boxes by investigat­ors in Paris demonstrat­ed parallels with the Lion Air crash and had been validated by US experts. US officials did not corroborat­e that.

With the prestige of one of the US’s biggest exporters at stake, Boeing has said the MAX series is safe, although it plans to roll out new software upgrades shortly.

Boeing has lost billions of dollars of market value since the crash, and halted deliveries of its best-selling model, one intended to be the industry standard but now under a shadow.

There were more than 300 MAX airplanes in operation at the time of the Ethiopian crash, and nearly 5 000 more on order. Media reports heaped further pressure on Boeing. The Seattle Times said the company’s safety analysis of a new flight control system known as MCAS (Manoeuvrin­g Characteri­stics Augmentati­on System) had crucial flaws, including understati­ng the power of the system.

It also said the Federal Aviation Administra­tion (FAA) followed a standard certificat­ion process on the MAX rather than detailed extra inquiries. The FAA declined to comment, but has said the process followed was normal.

The Wall Street Journal reported that federal prosecutor­s and the US Department of Transporta­tion were scrutinisi­ng the FAA’s approval of the MAX series, while a jury had issued a subpoena to at least one person involved in its developmen­t.

Boeing and the FAA declined to comment on that.

Last week, sources said investigat­ors found a piece of a stabiliser in the Ethiopian wreckage set in an unusual position similar to that of the Lion Air plane. Ethiopia is leading the probe, although the black boxes were sent to France and US experts are also participat­ing.

It was unclear how many of the roughly 1 800 parameters of flight data and two hours of cockpit recordings, spanning the doomed six-minute flight and earlier trips, had been taken into account in the preliminar­y Ethiopian analysis.

In Addis Ababa, a source who has listened to the air traffic control recording of the plane’s communicat­ions said flight 302 had an unusually high speed after take-off, before it reported problems and asked permission to climb quickly.

The inquiry is not only crucial to give closure to the families of the victims, who came from nearly three dozen countries, but also has huge financial implicatio­ns for Boeing and its many customers worldwide.
