What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted?
When thrust is reduced to less than weight, lift is also reduced and the wings can no longer support the weight.
The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced.
