An emergency slide fell off a Delta plane Friday morning, forcing the Los Angeles-bound flight to return to JFK Airport, sources told The Post.

The bizarre incident triggered an emergency alarm around 8:30 a.m. on Flight 520, which departed from the Queens airport an hour earlier, sources said.

Cops were still searching for the missing chute early Friday afternoon, and sources said he was believed to be in Jamaica Bay.

No injuries were reported.

The plane, a Boeing 767, ended up leaving JFK for Los Angeles International Airport just before 11 a.m., according to FlightAware.
