The National Transportation Safety Board (NTSB) said on 8 November that parts of the wreckage had been sent to its laboratories in Washington. The agency listed components from both wings and both engines, as well as the flight deck, vertical stabilizer, left elevator, aileron sections and multiple flap-track assemblies.
The Learjet 60 crashed in Palm Beach County, Florida, on 1 November, killing all nine people aboard. It was operated by Aurora Aviation under the Upper Jets name. The NTSB is investigating weather conditions and evidence of an in-flight breakup, but has not confirmed a cause; the investigation is ongoing.
