NTSB Sees Pre-Crash NBC4 Footage as Central Evidence in Chatsworth Helicopter Crash

The NTSB says NBC4’s live pre-crash helicopter video is the most important evidence for determining the probable cause of the Chatsworth crash; investigators will obtain a pristine copy for lab analysis of engine-speed changes and advisories, gather wreckage data, weather, maintenance logs, and interview witnesses, and review surveillance footage as part of a broader data-collection effort. A preliminary report is due in about 30 days, with the final probable-cause report potentially taking up to 18 months. Three people died—the NBC4 reporter Eliana Moreno, pilot George Marciniw, and bystander Edy Gutierrez Mejia—and authorities are seeking public tips via [email protected].
