Cockpit Seat Movement Inadvertently Triggered by Seatback Control

Boeing has issued an alert to airlines operating the 787 Dreamliner to inspect pilot seat switches following a harrowing incident that caused a LATAM Airlines jet to plunge suddenly during a flight from Australia to New Zealand. 

The unexpected dive, which occurred recently, resulted in injuries to 50 passengers and has raised concerns over the safety of the aircraft's cockpit design

The incident was reportedly triggered by an inadvertent engagement of a switch on the pilot's seat, which led to the seat moving forward and forcing the pilot into the control column. The movement caused the aircraft to pitch down abruptly.

In response to the incident, Boeing has recommended that airlines inspect the motorized cockpit seats for loose switches and follow instructions that include how to disable motors that move the seats. [The company described its advisory as a "precautionary measure" and noted that the investigation into the LATAM Airlines flight is ongoing.

The 787 Dreamliner, a two-aisle plane primarily used for long international flights, has been under scrutiny in the past for various technical issues. However, this recent event has specifically highlighted potential risks associated with the cockpit seat switches. Boeing's advisory aims to prevent any recurrence of such an event by ensuring that the switches are secure and cannot be accidentally engaged.

The FAA has not yet commented on the incident or Boeing's subsequent advisory. Meanwhile, LATAM Airlines has stated that the aircraft experienced a "strong shake during flight," and the cause is currently under investigation. This incident comes at a time when Boeing is still recovering from the fallout of the 737 MAX crisis. As investigations continue, many in the aviation industry are closely monitoring the outcomes and any potential implications for the design and operation of cockpit controls.

Boeing's approach in issuing the advisory is a step towards ensuring commercial aircraft safety and reassuring the passengers who fly on them.
