二 | Investigators said Friday they found hydraulic fluid leaking from a hose in the landing gear system of a FedEx plane that was forced to make an emergency landing this month in Chattanooga, Tennessee.The National Transportation Safety Board said that investigators also found a “discontinuity” in the wiring of an alternate system for lowering the landing gear.Video captured by emergency responders showed sparks flying after the Boeing 757 touched down on Oct. 4 with the left landing gear not fully extended. The plane ran off the end of the runway, but none of the three crew members were injured.The pilots reported that after taking off from Chattanooga, they got a warning about low fluid level and a lack of pressure in one of the hydraulic systems, and they decided to return to the airport. After getting an alert about the landing gear, the pilots declared an emergency. They did a low fly-by that allowed people in the airport tower to confirm that the left landing gear was not extended. The pilots circled and landed with the crippled gear. They were able to keep the plane going straight but couldn't stop until 830 feet beyond the end of the runway, the NTSB said in a preliminary report. Pilots used a slide to get out of the plane.The NTSB said an examination showed that a hose tied to a component used to activate the landing gear was leaking hydraulic fluid.The NTSB said it is continuing to investigate the incident.。维修人员计划在本周确定故障点,着手开展维修工作。截至当地时间13日下午,该国相关部门仍未发布地震灾情的评估报告。迄今所知受破坏最严重的地区是莫罗贝省、东高地省和马当省。地震引发了山体滑坡等次生灾害,对这些省份的建筑物和公共道路造成了破坏。当地人员伤亡情况仍不明。政府派出的直升机正在对偏远地区和农村灾区的受灾情况进行评估。在总理马拉佩的要求下,巴布亚新几内亚政府在11日地震当天成立了国家指挥中心,成员包括警察、国防军和其他相关政府机构的官员和专家。国家指挥中心正在汇总各方面信息,根据各地区灾情,确定并实施相应的救援行动。
