I thought lack of EICAS was the big certification holdup; is that fixed or waived, or grandfathered in ok?
I guess I’m asking is this a 7 problem, or a problem with the Max fleet as a whole?
Same exact system on the 8 and 9. Both variants were already certified before the TAI issue was discovered. Operators were sent a procedural bulletin about the problem and how to mitigate it until a permanent fix was developed. I’m pretty sure the FAA granted the EICAS waiver already for the 7 and 10 and they were well on their way to being certified under the TAI bulletin/temp fix until the door plug on the Alaskan MAX9 blew. That, combined with the two MAX crashes, and the FAA was not in the mood to waive anything associated with certifying the 7 and 10. Boeing knew it and withdrew the TAI waiver request… and here we are.
