请翻译在29日拆解后除了27日提到的桨叶弯曲和凹痕我们发现桨叶根部与桨毂的接触面有明显划痕随后桨叶被送到修理厂进行进一步维修。

After dismantling on the 29th, in addition to the previously mentioned blade bending and dents on the 27th, we found noticeable scratches on the contact surface between the blade root and the hub. Subsequently, the blades were sent to the repair shop for further maintenance.
