           Background: Certain rotor brake discs were found to be manufactured using an incorrect heat treatment process of the disc. This can lead to premature cracking and subsequent failure of the discs. This directive requires identifying certain discs, inspection of these discs and eventual replacement of these discs. Failure of the disc could cause damage to the rotor blades, nearby hydraulic and fuel lines, and subsequent loss of control of the helicopter.
