FAA Statement on closure to the New Shepard mishap investigation:
"The FAA has closed the Blue Origin New Shepard 23 mishap investigation. The final report cites the proximate cause of the Sept. 12, 2022, mishap as the structural failure of an engine nozzle caused by higher-than-expected engine operating temperatures. The FAA required Blue Origin implement 21 corrective actions to prevent mishap reoccurrence, including redesign of engine and nozzle components to improve structural performance during operation as well as organizational changes.
During the mishap the onboard launch vehicle systems detected the anomaly, triggered an abort and separation of the capsule from the propulsion module as intended and shut down the engine. The capsule landed safety and the propulsion module was destroyed upon impact with the ground. All debris landed within the designated hazard area. Public safety was maintained at all times with no injuries or public property damage."
