EASA 2020-0142

Supersedes but retains the requirements of EASA AD 2015-0097, which mandated repetitive inspections of certain part-numbered slider assembly pitch controls and replacement as necessary. Updated AD requires replacing affected parts with serviceable parts. Prompted by “unusual play” found on the slider pitch assembly controls during a scheduled 100-flight-hour inspection. Further investigation identified an excessive wear of the broaching of the slider assembly pitch control at the point of contact with the tail rotor shaft.
