The underarriage was a complicated structure, retracted or lowered in two operations by electric motors which were prone to breakdown. The undercarriage was a weak point of the Stirling, it sometimes collapsed under strong side loadings. The considerable height above ground, and the rake of the pilot's seat made it very difficult for the pilot to accurately judge touchdown attitude and precise ground position.

The picture on the right shows the weak point of the landing gear, it could cause the whole stalky structure to collapse under strong side-loadings.

Another unique feature of the Stirling was its twin castoring retractable tailwheels type Dunlop WS30
