CHAPTER 27 GROUND DEICING/ANTI-ICING PROGRAMS
Section 4 Maintenance Inspector Responsibilities: Evaluate an Operator’s Deicing/Anti-Icing Program
3-2238. GENERAL. The current regulations in Title 14 of the Code of Federal Regulations (14 CFR) parts 121, 125, and 135 are based on the “clean aircraft” concept. These regulations prohibit a takeoff with frost, ice, or snow (contamination) adhering to the wings, control surfaces, or propellers of an airplane. Sections 121.629, 125.221, and 135.227 require that each part 121/135 operator that conducts operations under conditions that may produce frost, snow, or ice accumulation must have one or both of the following:
· An approved aircraft deicing program
· An inspection program that ensures that aircraft are free of any accumulation of frost/ice/snow before takeoff
Altough I don't know the regulations of Russian aviation, those for commercial aviation in the United States and Europe are very clear in this. The Airbus De-icing system could not clear the wings with that much snow, altough they probably tested this before takeoff, it still seems not right.
