NTSB Chair Jennifer Homendy, testifying before the Senate Committee on Commerce, Science and Transportation March 6, said the agency is missing key details related to the aircraft involved in the Jan. 5 accident, despite multiple requests to Boeing.

“Boeing has not provided us with the documents and information that we have requested numerous times over the past few months, specifically with respect to opening, closing, and removal of the door, and the team that does that work at the Renton facility,” she said.

Boeing's reply to that seems to be:

“Our team has shared multiple times with the NTSB that we have looked extensively and have not found any such documentation,” the letter said. “We likewise have shared with the NTSB what became our working hypothesis: that the documents required by our processes were not created when the door plug was opened. If that hypothesis is correct, there would be no documentation to produce.”
