The invention relates to an ejection separation mechanism of a flight recorder, which comprises an ejection spring (3) made of nickel-titanium memory alloy; a hook body (31) is arranged at the top end of the ejection spring (3); a clamping piece (41) is arranged on the bottom surface of the ejection base (4), and the clamping piece (41) is clamped with the hook body (31); a mounting stand column (2) is arranged on the mounting base (1), and the ejection spring (3) is arranged on the mounting stand column (2) in a sleeving mode; the installation stand column (2) is provided with a hollow inner cavity, and the electric heating piece (5) is arranged in the inner cavity. The lower end of the electric heating piece (5) is connected with a power supply wire (6) which penetrates out of the installation base (1) and then is connected with a power module. According to the flight recorder, the nickel-titanium memory alloy is adopted as the actuating mechanism, ejection separation of the flight recorder when the ejection condition is met can be achieved, and the actuating reliability of the ejection separation mechanism is improved.
