Slide/Raft Improvement
Section titled “Slide/Raft Improvement”By: Fabien SAUVAGE Emergency Equipment Engineer Customer Services
1 Introduction
Section titled “1 Introduction”For years Airbus has been encouraging operators to report all escape slide and slide raft deployments, whether scheduled or inadvertent, successful or unsuccessful, in order to improve their reliability.
The number of reportings, however, has steadily decreased and represents only a fraction of the estimated number of deployments.The purpose of this article is to draw attention to the need for regular and extensive feed back of slide deployment information to Airbus.
2 Regulatory requirements
Section titled “2 Regulatory requirements”Every 36 months, operators have to perform a certain number of slide deployments, which is a function of the number of doors on the considered type of aircraft, irrespective of the fleet size. A330/A340 fleets can be combined for common doors, therefore an operator equipped with a mix of A330/A340 will have to deploy 4 slides, as this type of aircraft is equipped with 4 doors per side (5 on the A340-600).
These deployment may be performed on either side and do not all have to be performed on the same aircraft. Inadvertant deployments may not be used to satisfy these requirements.
3 Product improvement
Section titled “3 Product improvement”4 Recommendations
Section titled “4 Recommendations”The Aircraft Maintenance Manual and SIL 25-124 specify how deployment tests should be performed. The last page of SIL 25-061 Rev 3 includes a slide/raft deployment reporting form to be forwarded to Airbus Customer Services.
Based on the above requirements, Airbus has estimated that on the A330/A340 familly alone, approximately 140 deployments should have been performed in 2007. Only 14, however, have been reported to Airbus, of which 7 were successful.
Slide reliability is increasing every year because of the continuous system and component improvements and thanks to the input from our customer airlines. Exhaustive deployment reporting is key to a better overview of the slide and slide raft reliability, and allows to identify areas that could be improved. Close monitoring and reporting of in-service occurrences is essential for an efficient event analysis and associated engineering investigation/resolution launch.
5 Conclusion
Section titled “5 Conclusion”In order to be able to improve the slide/rafts reliability, and hence passenger safety, we do encourage the reporting of all deployments, whether successful or unsuccessful, scheduled or inadvertent.

滑梯/救生筏改进
Section titled “滑梯/救生筏改进”作者：法比安·索瓦奇 应急设备工程师 客户服务部
多年来，空客一直鼓励运营人报告所有滑梯和滑梯救生筏的放出情况，无论是计划内的还是意外的、成功还是失败的，以提高其可靠性。
然而，报告数量持续下降，仅占估计放出数量的一小部分。本文旨在引起关注，强调需要定期且广泛地向空客反馈滑梯放出信息。
2 法规要求
Section titled “2 法规要求”每36个月，运营人必须完成一定数量的滑梯放出，这是所考虑机型舱门数量的函数，与机队规模无关。A330/A340 机队可合并计算通用舱门，因此配备 A330/A340 混合机队的运营人需要放出4个滑梯，因为该机型每侧配备4个舱门（A340-600 为5个）。
这些放出可以在任一侧进行，无需全部在同一架飞机上完成。意外的放出不得用于满足这些要求。
3 产品改进
Section titled “3 产品改进”《飞机维护手册》和 SIL 25-124 规定了应如何进行放出测试。SIL 25-061 Rev 3 最后一页包含滑梯/救生筏放出报告表，应提交给空客客户服务部。
基于上述要求，空客估计，仅 A330/A340 系列，2007年就应该已完成约140次放出。然而，只有14次向空客报告，其中7次成功。
由于系统和部件的持续改进以及客户航空公司的反馈，滑梯可靠性每年都在提升。全面的放出报告是更好地掌握滑梯和滑梯救生筏可靠性的关键，并有助于识别可改进的领域。密切监控和报告在役事件对于有效的事件分析和相关工程调查/解决方案启动至关重要。
为了能够提高滑梯/救生筏的可靠性，从而提高乘客安全性，我们确实鼓励报告所有放出情况，无论是成功还是失败、计划内还是意外。
