               Background: This AD is issued to prevent uncommanded engine accelerations, which could result in an engine overspeed, uncontained engine failure, and damage to the aircraft. The requirements of this AD supersede the requirements of AD/CF34/3 which has been cancelled. Engines in compliance with AD/CF34/3 may be affected by the requirements of this AD.
