Boeing has been sanctioned by the National Transportation Safety Board after the company disclosed information not intended for public release about the 737 Max door plug investigation.

The NTSB said Boeing violated a party agreement by disclosing investigative information and giving an analysis of previously disclosed factual information during a Tuesday media briefing about quality improvements on its planes.

Boeing will retain its party status but lose access to unpublished investigative information produced by the NTSB.

"We deeply regret that some of our comments, intended to make clear our responsibility in the accident and explain the actions we are taking, overstepped the NTSB's role as the source of investigative information," the company said. "We apologize to the NTSB and stand ready to answer any questions as the agency continues its investigation."

The agency also plans to subpoena the company to appear at an investigative hearing Aug. 6-7 in Washington, D.C., where it won't be permitted to ask questions.

Boeing has been the subject of multiple federal investigations in the wake of the Jan. 5 incident when an Alaska Airlines lost a door panel in flight.
