WASHINGTON (Reuters) - Boeing ( BA ) said Friday it told airlines operating 787 Dreamliners to check flight deck switches after a sudden mid-air dive by a LATAM Airlines 787 plane left more than 50 people injured.

The Air Current, an aviation industry publication, reported Wednesday the movement of a flight deck seat is a key focus of the probe of Monday's flight. Boeing ( BA ) said Friday it took the precautionary measure of reminding operators of a 2017 service bulletin detailing instructions for inspecting and maintaining flight deck seat switches. "We are recommending operators perform an inspection at the next maintenance opportunity," Boeing ( BA ) said Friday.
