Damage produced by load testing of the elevator mechanism (left), compared with the damage seen on the accident aircraft (right). As a final test, with the inboard geared-tab linkage of the test elevator locked in an overcenter position, a TEU force was applied to the elevator using the forklift, simulating the conditions during the takeoff roll.
To maintain level flight requires increased positive (up) elevator to increase the angle of attack, increase the total lift generated and keep the vertical component of lift equal with the weight of the aircraft. This cannot continue indefinitely. The total load factor required to maintain level flight is directly related to the bank angle ...
The TK Elevator Test Tower, an elevator test tower in Rottweil, Baden-Württemberg, Germany. An elevator test tower is a structure usually 100 to over 200 metres (300 feet to over 600 feet) tall that is designed to evaluate the stress and fatigue limits of specific elevator cars in a controlled environment.

Cause is found to be a broken brass pin in the port elevator pump assembly that allowed the elevator to deploy, the pin having been worn out during months of ground test runs. Brass is subsequently replaced by steel pins, and problem is solved. [71] An AD-4 Skyraider of VA-115 crashes aboard USS Philippine Sea (CV-47). 12 December
The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a downward force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity.
