The former "Full House" actress was departing Dallas on American Airlines flight 2421 when pilots were forced to abort plans for take-off and return to the gate after spotting smoke permeating from one of the aircraft's engines.

All 211 passengers were then transferred onto a second Boeing 767. A company spokesperson tells TMZ the passengers suffered a two-hour delay.

This isn't the first time Olsen has been caught up in a flight scare. In 2010, Olsen was traveling to New York with her then-boyfriend Justin Bartha when they had to make an emergency landing due to a mid-air blaze.
