What to do
Operators of AW169 helicopters with affected yaw pedal assemblies must modify or replace these parts within 50 flight hours or 3 months from the effective date of 24 October 2019, whichever occurs first. After modification, affected parts must not be reinstalled, and no affected parts may be installed on any helicopter from the effective date onward. Compliance must follow the instructions in Leonardo Service Bulletin 169-147.
Summary
EASA Airworthiness Directive 2019-0252 is an airworthiness directive issued by the European Union Aviation Safety Agency concerning Leonardo S.p.A. AW169 helicopters. It addresses a safety issue related to the pilot and co-pilot yaw pedal assemblies, specifically parts with certain part numbers that lack a required modification marking. The directive mandates modification or replacement of these affected parts to ensure continued safe operation of the helicopters.
What changed
This directive introduces a mandatory modification or rework of the pilot and co-pilot yaw pedal assemblies on AW169 helicopters that have affected parts installed. It requires re-identification of the modified parts according to Leonardo Service Bulletin 169-147. The directive also prohibits installation of affected parts on any helicopter after the effective date.
Why it matters
This directive is critical for aviation professionals because it addresses a potential failure in the yaw control system caused by broken adjustable devices in the pedal assemblies. Failure to comply could lead to reduced yaw control, compromising flight safety. Operators, maintenance organizations, and compliance teams must ensure affected helicopters are modified promptly to maintain airworthiness and regulatory compliance.
