An interviewed aviation expert also said that probably the exploding engine severed hydraulic lines to the tail control services, preventing the pilots from continuing the departure on a single engine.
Isn´t the elevator and rudder control system of the MD 8x fully mechanical, using small tabs and air pressure to move the control surfaces ? Or does this just apply to the elevator ?
On the other hand, how high is the risk of losing an elevator tab due to an uncontained engine failure? Will one Elevator be enough to control the aircraft?
