The NTSB is confirming updates from earlier this month, which stated that thrust reversers (which help slow an aircraft) were applied differently at the time of the plane’s landing at LGA back in March. The latest information confirms that the engine pressure ration (which measures the thrust) was higher on the left side of the plane than the right. The engine reached peak reverse thrust of 2.07 engine pressure ratio on the left, and 1.91 EPR on the right, between six and seven seconds after touchdown. When there’s a difference, the airplane will usually follow the engine with the higher power, the left side in this case.
