What to do
Operators of Leonardo AW169 and AW189 helicopters must perform the required conformity checks on affected tail rotor actuators within 30 flight hours or 30 days from 13 February 2019. If any actuator input lever fails the check, it must be replaced with a serviceable part according to the instructions in the applicable Leonardo Alert Service Bulletins. Installation of affected parts is prohibited from the effective date onward.
Summary
EASA Airworthiness Directive 2019-0019 is an airworthiness directive issued by the European Union Aviation Safety Agency concerning Leonardo S.p.A. AW169 and AW189 helicopters. It addresses inspection requirements for the tail rotor actuator input lever, specifically for parts with Part Number 6F6730V00331 and serial numbers up to 489, excluding those marked with UTC Aerospace Systems Service Bulletin 67-0007. The directive mandates conformity checks to ensure correct installation and functionality of the tail rotor actuator input lever.
What changed
This new airworthiness directive introduces a one-time conformity check of the tail rotor actuator input lever on affected Leonardo AW169 and AW189 helicopters. It requires operators to inspect the affected parts within 30 flight hours or 30 days and mandates replacement of any non-conforming parts with serviceable ones. Additionally, it prohibits installation of affected parts from the effective date.
Why it matters
This directive is critical for aviation professionals because incorrect orientation of the tail rotor actuator input lever can lead to bearing slippage, potentially compromising tail rotor functionality and flight safety. Operators and maintenance organizations must comply to ensure continued airworthiness and prevent unsafe conditions. Compliance teams need to track and enforce these inspections and part replacements to meet regulatory requirements.
