The FAA is probing a Southwest Airlines incident where a Boeing 737-800 lost an engine cover during takeoff at Denver International Airport.

The flight was forced to make a safe emergency landing, with passengers witnessing the engine cowling detach and strike the wing flap.

This event comes after a similar issue with a Boeing 737 Max 9 that resulted in the grounding of 171 aircraft.

The aircraft in question was certified airworthy in May 2015 and began service a month later.

Boeing is under scrutiny following multiple incidents, including one where a door plug panel fell off an Alaska Airlines 737 Max 9, sparking a criminal investigation.

The FAA is also examining other recent Southwest Boeing engine incidents, highlighting ongoing safety concerns.

These repeated issues have led to increased traveler apprehension regarding the safety of Boeing aircraft.
