Why do you consider the A220 inflight shutdown for AirTanzania unconfirmed?https://simpleflying.com/air-tanzania-a ... -shutdown/
The FAA has already issued an Airworthiness Directive for the A220 engine inspections. What we don’t know is if the Air Tanzania event is related to that issue or if it is a new issue
Please note, simpleflying is just using the original ACT-News story as only source. They have no new or independent information. ACT News is just one single guy. I am still waiting for a independent second source, best an statement by Air Tanzania, PW or Airbus or any other News-service, who has independent collected and verified some information.
If you verify the original ACT News in #1, you will recognize, that no sources are stated, from where he has the information, that it was an engine failure, that has forced the jet to return. No statements by passengers, crew, airport authorities or airline, he is just saying (or does he just believe that) it was an engine failure. Also possible in my opinion: the author has just seen on flightradar24, the jet has returned to the start airport, he does not know the reason and as "engine failures are just now common for A220", even FAA warning is announced days before, "it must have been the next engine failure", what else????.", Who knows, it can be also be an issue with instruments, avionic, hydraulic e.g., perhaps the pilot was so stupid to pull a can full of coke over the cockpit instruments, or a passenger got a heart attack. The jet was parked for three days and than back in the air, so three days for repair? This also can be for spend time for additional checks regarding a landing above maximum landing weight e.g.
This is the reason, why I am still asking for an independent second source, regular/daily verifying, if I am able to find an additional one e.g. (and I have started this thread).
In my opinion, this inflight engine failure/shut down is still to be stated as unconfirmed,
