FAA will review the safety procedures of United Airlines, particularly affected by incidents with Boeing planes. United Airlines owns the largest fleet of 737 MAX 9s, with 79 of these aircraft.

“We have a strong safety culture at United. Nevertheless, the number of security-related events in recent weeks has rightly caused us to pause and evaluate whether we can and should do something differently,” says a vice-president of the airline to staff. The FAA will also suspend various certification activities for a period of time.
