L-39NG passes key fuselage strength test

Aero Vodochody’s L-39NG has passed fuselage strength tests, as the company works towards certification of the advanced jet trainer. Using the fuselage of aircraft 7002, which is earmarked for static trials, the test saw the structure initially taken to the limit load, which corresponds to the maximum possible load during flight. Subsequently, this was increased to the ultimate load, or 150% of limit load. It was only at 110% of this higher level that a structural failure occurred.
