Emergency slide falls off Boeing plane, forcing LA-bound Delta flight to return to JFK

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

The freak accident set off an emergency alarm around 8:30 a.m. aboard Flight 520, which had departed the Queens airport an hour earlier, sources said.

The crew — who had reported a vibration, according to the FAA — had no choice but to return to JFK, on runway 22L, according to the sources.

Cops were still searching for the missing chute early Friday afternoon and sources said it’s believed it could be in Jamaica Bay.

There were no injuries reported.

The plane is a Boeing 767, which wound up departing JFK for Los Angeles International Airport just before 11 a.m., according to FlightAware.

A Port Authority spokeswoman said there is “an ongoing investigation into what took place.”

The airline did not immediately respond to a request for information.
