Agreed. I know that FAA has so many other problems to deal with, hence the issuance of 56 Airworthiness Directive released in the past 60 days. The question I would like to know the answer to is, "How long does it take to issue an Airworthiness Directive from the time the problem was found?"

Coming up to 4 months of no results on the 15 second test is very troublesome and uncalled for.
