Well this looks like its going to soak up a heap of the TAIC budget for the next few years. I see pprune comments suggesting an electrical power failure followed by an uncommanded control inputs.

Really not good. I am glad they managed to get down and land.

Chile will be lead I think? International airspace, their aircraft. TAIC will mainly be involved in evidence gathering I think.

Do they swap out the FDR and CVR, or just download the data?

The DGAC said that this event is officially in charge of the Accident Investigation Commission of New Zealand, where a Chilean expert will travel to join the team.

Should I be nervous about getting on a Dreamliner in June?

No. If there is an issue then it is clearly caused by a very rare set of conditions.
Take care crossing the road, it will improve your safety more than avoiding B787-9s.

Transport watchdog deciding on whether to investigate:

The Transport Accident Investigation Commission has yet to open an investigation into the incident.

They provided this statement:

"The Commission is gathering information to inform a decisions as to whether to open an inquiry."

So have the crew been interviewed to get their account? First interviews should be done ASAP surely, by all means have a video connection with DGAC to assist.

CVR and FDR are removed and sent to an approved lab for downloading for an investigation.

Periodic downloads are done in the field to make sure the boxes are still working as advertised but doing it in a lab is safer. Evaluation of the data however (FDR at least) requires OEM software and a hardware dongle. Mucho $$$

Initial reports of the screens going blank seem to have been a bit far fetched. It now seems likely that a crew member (possibly cabin crew) inadvertently adjusted a crew seat too far forward and this pushed the control column forward.

Oopsie.

Cheers.
Boeing have issued an advisory to check for loose rocker switches (under a cover at the top back of B787 seats) that can be activated by leaning on the cover.



Slightly earlier story.

Next question is the CVR length on LATAM B787s. Bet NTSB was yelling at TAIC about making sure the CVR circuit breaker was pulled!

DGAC has issued the preliminary report, according to reports of reports I've seen. Doesn't sound like any surprises.
www.worldstockmarket.net/latam-flight-crashed-after-cabin-seat-involuntary-movement-says-report/

A preliminary report on the sudden descent of about 120 meters of a Latam Airlines Boeing 787 aircraft during a flight from Australia to New Zealand on March 11 highlighted that “the seat on the left side of the cabin, with the captain sitting in it, started an involuntary movement forward.”

The document was created by the Accident Prevention Department of the General Directorate of Civil Aeronautics of Chile (DGAC). Both the captain and the first officer who piloted the flight are Chilean citizens, according to the text.

The reasons for the incident are being investigated by the DGAC Aviation Accident Investigation Board.

So far, the crew involved in the case and the crew that transported the aircraft from Chile to New Zealand the day before have been interviewed.

In addition, reports were collected “from maintenance employees who checked the condition of the captain's seat and those who worked on its replacement, both in Australia, New Zealand and Chile”, as well as the history of events associated with seats in the captain's cabin. plane.

US regulators have issued a directive for the inspections of Boeing 787 cockpit seats, after a spate of “uncommanded” seat movements reported among operators.

The US Federal Aviation Administration (FAA) notice also follows a March incident involving a LATAM 787, where an involuntary forward shift in the pilot’s seat led to an in-flight upset that caused the plane to experience a “sudden unintentional” loss of altitude.
