NTSB Calls NBC4 Crash Video Key Evidence in 3-Death Helicopter Probe

Summary
Aboard video from the NBC4 helicopter is now the NTSB's top lead, with investigators seeking a pristine copy for lab analysis after Tuesday's Chatsworth crash killed 3.
Audio on the recording appears to capture engine speed changes and likely pilot warning tones, evidence investigators say could help determine whether a mechanical failure preceded the crash.
Investigators are also collecting witness accounts, nearby surveillance footage, wreckage data, maintenance logbooks and weather records before moving the helicopter to a secure facility for further examination.
The Bell helicopter went down around 7 p.m. between commercial buildings near an earlier fatal Metro bus crash, killing reporter Eliana Moreno, pilot George Marciniw and 29-year-old Edy Gutierrez Mejia on the ground.
A preliminary report is due in 30 days, while the final probable-cause finding could take up to 18 months.
