A Southwest Airlines jet that experienced engine failure and had to make an emergency landing earlier this month landed in Everett for repairs Monday.

The aircraft has been released from the National Transportation Safety Board’s investigation and was flown to Paine Field, according to Southwest Airlines.

The plane was flown to Aviation Technical Services facilities, which conducts major services on Boeing aircraft.

The left engine has already been replaced.

The jet is not back in service, according to Southwest.

Southwest Flight 1380 was traveling from New York City to Dallas on April 17 when one of the jet’s engines failed, leading to an emergency landing. One passenger died after a window broke and the suction pulled her partially out.
