Boeing has a program called Fleet Team Digest and Service Related Problems which address potential mechanical or airframe failures to QC departments. It's up to the airline to address the issues and have their maintenance departments make time to complete these inspections to be completed by a certain date. These dates do not become mandatory until their made into Advisory Directives from Boeing Engineers. That is why this was never addressed. The list of Fleet Team Digests and Service Bulletins for the 777 along is very long. These incidents are going to continue to occur without well established maintenance procedures carried out by the company operating these aircraft with whatever configurations they have.
I am a maintenance controller and aircraft mechanic who has access to information like this. The 777 is able to operate with 1 engine running. There are certain line numbers of 777s that were made that have this issue. I assure you it's more than one and the FAA will issue an AD that must be complied with. All AD are mandatory per the FAA.
