29. 在本报告所述期间，联索支助办运营和维护 19 架飞机(6 架固定翼和 13 架旋翼飞机)。由于该国境内治安情况恶化、青年党袭击非索特派团部队以及各主要补给线受不安全和降雨影响而无法使用等因素，联索支助办严重依赖空中支援。鉴于上述所有因素，并为解决因未根据与会员国签订的协助通知书部署 3 架军用旋转翼飞机而造成的重大支援缺口，联索支助办在本报告所述期间部署了 3 架旋转翼飞机用于后勤行动，超出了核定机队 5 架后勤直升机的兵力。出于安全原因，联合国文职人员在特派团内的旅行继续受到限制，联索支助办严重依靠商业第三方供应商以及特派团援助部队的工程和运输部门建造设施，并通过陆路运输物资。
29. During the reporting period, UNSOS operated and maintained 19 aircraft (6 fixed-wing and 13 rotary-wing). Factors such as the deteriorating security situation within the country, Al-Shabaab attacks on AMISOM troops and the inability to use the main supply routes, which were affected by insecurity and rains, created heavy reliance by UNSOS on air support. Given all of the above factors, and to address critical support gaps created by the non-deployment of three military rotary-wing aircraft under a letter of assist with a Member State, UNSOS deployed three rotary - wing aircraft for logistics operations during the reporting period, in excess of the approved fleet strength of five logistical helicopters. As United Nations civilian staff continued to face restrictions on in-mission travel for security reasons, UNSOS relied heavily on commercial third-party vendors and engineering and transportation elements of mission enabling units for the construction of facilities and the transportation of materiel by road.
