Russian Presidential Administration criticized, and the general layout of SSJ-100, in particular, is too low position of its engines. As stated in the above letter, the layout of the aircraft, "the conclusion of the Ministry of Transport of Russia and the results of the research of TsAGI, requires the adoption of additional security measures in its use of regional airports in Russia." Simply put, to exploit new Russian regional aircraft to regional airports in Russia is dangerous! The reason - poor quality of the surface of the runway and the threat of falling into the engines during taxiing and take-off of foreign objects. It would seem - a serious problem, but how it responds to GHS guidance? Memorable answer to this question was given in an interview General Director of GSS Victor Subbotin: "I am surprised, why such questions are asked by us ... not our job after all - to engage aviapokrytiyami, we are developing the aircraft."
