The AD came out in January 2020, before the pandemic, when the industry was still running full speed. The 787 has been the most used type in the fleet in the intervening time. In fact the issue was originally described in a Boeing Service Bulletin in March 2019. I wonder how many other 2019 Service Bulletin's the airline has not yet got round to.
The AD also came out when Alex "Every day I think of ways to save money" Cruz was still CEO at the airline. I suspect any AD with 36 months to comply was under instructions from the top not to even order the parts until July 2021. Note the accident took place less than a month before the final compliance date. It's a shame the AAIB did not ask to see the forward maintenance schedule for this aircraft (and all the other 787s) in the days ahead for when it was scheduled to be fitted.
