The 310R stalls at 79 knots clean and 72 knots (some sources say 70) with gear and flaps down; probably at 75 knots or so with flaps 20. Aft CG reduces longitudinal stability and makes the airplane more sensitive to small pitch commands; some combination of unaccustomed loading, confusing visual impressions of excess speed and lack of familiarity with the feel of the airplane caused the pilot to bleed off — unwittingly, I assume — the 18-knot cushion that separated approach speed from stalling speed. One of the surviving passengers reported that the wings were rocking and he felt the airplane being “tossed around” by wind. The wing rock and the sensation of being tossed around were very likely due to the wing beginning to stall. By the time it occurred, the airplane was probably less than 200 feet above the ground, a height at which the proper reaction to an inadvertent stall, pushing the nose down smartly, may be overwhelmed by an instinctive, and fatal, impulse to pull back on the yoke.
