FAA details steps needed to get Boeing 737 MAX flying
https://www.reuters.com/article/us-s...-idUSKBN205100
SINGAPORE (Reuters) - The U.S. Federal Aviation Administration is narrowing the issues needed before it can conduct a certification test flight on the grounded Boeing (BA.N) 737 MAX, but will not commit to a timetable for lifting a flight ban, its top official said.
“We are following a very diligent process and it is important that we stay focused on the process and not on the timeline,” FAA Administrator Steve Dickson told reporters.
“We are following a very diligent process and it is important that we stay focused on the process and not on the timeline,” FAA Administrator Steve Dickson told reporters.
FAA details steps needed to get Boeing 737 MAX flying
Speaking to reporters in Singapore, FAA Administrator Steve Dickson said there was no timetable either for a crucial certification test flight or for a decision to end the 11-month-old global grounding, imposed after two fatal crashes.
But he said the certification flight was approaching . He listed steps lasting about a month between the certification flight and the earliest possible ungrounding. However, this does not account for any surprises in testing.

Actually the story pretty clearly says that he didn't send or receive any of the emails himself. It says nothing about why he was fired; it only references the timing. Correlation does not imply causation.

1. The bad news is that there is a bunch of dangerous debris left in the MAXes….The good news is that the planes are already grounded for being unsafe anyway...so who's laughing now, huh?
2. The bad news is that there is a bunch of dangerous debris left in the MAXes… The good news is that they found a bunch of high quality tools that they thought were permanently misplaced...

They’d have to inspect the fuel tanks anyway, for water or other contaminants from disuse and even old fuel if there’s any left in the mothballed aircraft, AFAIK, from what I learned from the 309th Aerospace Maintenance and Regeneration Group.

"(Reuters) - Boeing Co has found debris in the fuel tanks of dozens of undelivered 737 MAX jets amid ongoing inspections as the Chicago-based planemaker struggles to restore the trust of airlines and the wider public in the grounded fleet.Boeing found debris in the fuel tanks of about 35 aircraft, a company spokesman confirmed on Friday. A person familiar with the matter told Reuters that more than 50% of the undelivered 737 MAX jets inspected thus far have had debris found in them."
