The Department of Buildings says a crane collapse that killed a man in Manhattan in February was caused by "a series of errors by the crane operator."
DOB says the operator failed to secure the crane the night before the crash and also lowered the crane's boom at an improper angle the morning of February 5, causing it to be unstable.
The crane operator's license has been suspended, according to DOB, who says it will try to get the operator's license permanently revoked.
The crane collapsed along two blocks on Worth Street in TriBeCa.
David Wichs, 38, was killed as he was getting out of his car.
Three others were injured.
The crane was at 60 Hudson Street, the old Western Union building, since last week to replace heavy equipment on the roof.
After the incident, Mayor Bill de Blasio issued new restrictions for operating crawler cranes during windy conditions.
They include doubling fines for not safeguarding equipment, and requiring residents and business owners be notified about crane activity.
