AAIB investigation to Boeing 737-4Q8, OE-IAG
Main gear shimmy on landing on Runway 25 at Belfast International (Aldergrove) Airport, 4 October 2016.
Summary:
On landing, an intense vibration developed, the crew cancelled the automatic brakes and thrust reversers, as there was sufficient runway, and the aircraft came to a stop. The lower torsion link was found to have fractured on the right main landing gear (MLG) possibly due to excessive MLG vibration (shimmy). The cause of the vibration could not be established but may have been related to the speed of the aircraft on landing, and possibly a problem with the shimmy damper or freeplay within the joints associated with the upper and lower torsion links.
