DLH 2904 flight from Frankfurt to Warsaw progressed normally until WarsawOkecie Control Tower warned the crew that windshear existed on the approach to Runway 11.
This had been reported to WarsawOkecie Control Tower by DLH 5764 who had just landed.
A very light touch of the runway surface with the landing gear and it consequential lack of compression of the left landing gear resulted in delayed deployment of spoilers and thrust reversers.
