History

Flight 529 left the ramp area at Atlanta at 12:10, and took off at 12:23. At 12:43:25, at 18,100 feet a thud was heard throughout the plane. One of the blades of the propellor on the left had engine had failed, distorting the engines profile.

A propeller can be seen as a rotating fin in water or a wing in air. ...

Although the plane can fly with one engine simply malfunctioning, the distortion of the engine caused excessive drag and loss of lift on the airplane, causing it to descend. For a solid object moving through a fluid or gas, drag is the sum of all the aerodynamic or hydrodynamic forces in the direction of the external fluid flow. ... Lift consists of the sum of all the fluid dynamic forces on a body perpendicular to the direction of the external flow approaching that body. ...

The pilots initially tried to divert the plane back to Atlanta for an emergency landing, and the plane was turned to fly to West Georgia Regional Airport. But the airplane was unable to stay in the air that long, at 12:52:45, the airplane struck the tops of the trees and crashed into a field near Carrollton.

Casualties

In the subsequent fire, which started about one minute after impact, the pilot was killed, and several passengers were seriously wounded. Seven passengers died within 30 days of the crash, bringing the official death toll to 8. An eighth passenger died four months after the crash from the burn injuries. None of the passengers or crew escaped without any injuries. It has been suggested that Firetending be merged into this article or section. ...

Cause

The crash was determined to be caused by the failure of the propellor. This happened because of undiscovered metal fatigue. The NTSB criticized Hamilton Standard who had maintained the engines for "inadequate and ineffective corporate inspection and repair techniques, training, documentation and communication" and both Hamilton and the FAA for "failure to require recurrent on-wing ultrasonic inspections for the affected propellers." In materials science, fatigue is a process by which a material is weakened by cyclic loading. ...
