国际航空运输协会的报告指出,由于腐蚀导致民用飞机的定期维修和部件更换的直接费用每飞行小时为5——12美元,其成员单位每年用于飞机腐蚀修理费用达2亿美元。腐蚀不仅在经济上导致严重损失,而且还会带来安全问题。为了解决这一问题,我们必须予以严格监控与防护。一、飞机的老龄问题由于关键受力部件发生腐蚀突然出现断裂而引起的飞机失事,会严重危及人身安全。适航性对腐蚀防护要求愈来愈严,特别是飞机老龄化问题。西方许多国家由于经济的不景气已迫使许多航空公司延长了飞机的原定使用寿命。根据1988年的估计,全世界民航机的使用寿命大约是11 IATA’s report states that the direct costs of routine maintenance and replacement of parts of civil aircraft due to corrosion are $ 5 to $ 12 per flight hour and that its member units cost $ 200 million per year for aircraft corrosion repair. Corrosion not only leads to serious economic losses, but also to security problems. In order to solve this problem, we must strictly monitor and protect it. First, the aircraft’s aging problem As a result of the sudden failure of the key components of corrosion corrosion caused by the plane crash, will seriously endanger personal safety. Airworthiness Corrosion protection requirements are getting more and more strict, especially the problem of aircraft aging. Many western countries have forced many airlines to extend their original aircraft life due to the economic downturn. According to 1988 estimates, the useful life of civil aircraft around the world is about 11
