BOEING IS HAVING A BAD DECADE: Boeing’s 777 Back in the News Over Maintenance Issue. “The FAA on April 9 proposed an airworthiness directive for inspections of all models of Boeing’s 777 jetliner. The directive is based on the agency’s discovery of five 777s of various models with missing rivet heads used to join the aircraft’s skin. This directive is the second to affect the 777 in less than two months. The previous one was issued following the explosion of a Pratt & Whitney Canada PW 4000 engine in February.”
