（案例分析）2017年9月3日，某机组驾驶飞机执行扎兰屯-海拉尔航班，在海拉尔最后进近阶段副驾驶接到管制指令的同时，机长下达指令“打铃，放轮，襟翼30”，副驾驶接到机长指令“打铃，放轮，襟翼30”后，由于疏忽，在场高1748ft选择45°襟翼，但未放下起落架手柄，机组发现起落架未放下后复飞。二次进近正常落地。请问机组可能存在哪些问题？(Case Analysis) On September 3, 2017, a certain crew flew the aircraft to carry out the Zhalantun-Hailar flight. At the same time as the copilot received the control instruction during the final approach phase of Hailar, the captain gave the instruction "Ring, gear down, and flaps 30”, after receiving the command from the captain “Ring, gear down, and flaps 30”, the copilot, due to negligence, selected the flaps 45° at 1748ft AGL, but the landing gear lever was not selected down. The flight crew found the abnormal situation of landing gear and excuted a missed approach. The second approach was made and ended with a normal landing.
