Airbus knew of software vulnerability before A400M crash

Wed Nov 08, 2017 12:09 pm

Apparently Reuters ( https://uk.reuters.com/article/us-airbu ... KKBN1D819P ) has gotten access to a confidential Spanish military report.

It confirms what we already knew, that data was wiped on 3 of 4 engines as a part of a failed software installation and never re-programmed.

What is new is:

The report also said the engine-makers had warned Airbus and the European Aviation Safety Agency (EASA) in October 2014 that software installation errors could lead to a loss of engine data, and that technicians may not receive any warning before take-off that a problem had occurred.

And even though this was a known issue the pilots were not made aware of this issue nor given any guidance on how to deal with it. In theory if they knew the symptoms (engines go to full power) then they could have known to never throttle down the engines and could in theory have safely landed the aircraft.

And there's a squabble over control over the installation of the software on the engines. Airbus says it should be its employees and equipment should be used whereas EPI is saying it should be theirs because the engine is certified to civil standards. The report is saying that since the facility is a military one that Airbus's point of view is correct.

Also:

Airbus argues it was right to install the software itself because it had authority under military rules, but says the design did not meet its specifications - a claim denied by EPI, according to the three people familiar with the inquiry, who declined to be named due to the sensitivity of the matter.

Back where it matters this is IMHO a major design failure in the FADEC Software.
( Omission of an integrity check at boot up. )
Who may update or not is a bit of a detracting squabble.
Design process of the FADEC already shew some strange problems
like the wrong tool set for a certifiable product.
