27 March 1964 Cosmos 27 During unpowered coast in parking orbit the escape stage Block L lost stable attitude due to a loss of the the power circuit of the pneumatic valves of the attitude control and stabilisation system.
20 April 1964 At T+340 sec the launcher's control system failed and the engine of Stage 3 cut off prematurely due to loss of a section of the circuit between BOZ's storage battery and a DC transformer.
23 November 1965 Cosmos 96 At T+528 sec, during the final thrust phase of the Block I's 8D715K engine, one of the combustion chambers blew up due to a tear in the fuel pipeline. This resulted in an abnormal separation of the upper stages.
01 March 1966 Cosmos 111 The escape stage Block L lost roll control during unpowered coast in parking orbit because the axis of the course regulator of the control system jammed in the zero position. The stage's engine was not fired.
