WASHINGTON (Reuters) - Boeing Co is planning to send a bulletin to 737 MAX jet operators as soon as Wednesday advising them of the procedure for dealing with erroneous cockpit readings that could cause a dive, a person briefed on the matter told Reuters.

The advice is based on preliminary information gathered in the investigation of a Lion Air flight that crashed in Indonesia last week killing all 189 on board, the person said.
