What to do
Operators of affected Airbus A350-941 and A350-1041 aeroplanes must inspect the washers on engine mount primary pins and thrust link pins within 30 days of 2 August 2019, following Airbus AOT A71P016-19 instructions. If incorrect washers are found and pins are in place, replace washers before the next flight. If pins are axially moved, contact Airbus for approved instructions and comply accordingly. Inspection results must be reported to Airbus within 60 days after inspection.
Summary
EASA Airworthiness Directive 2019-0175 is an airworthiness directive affecting Airbus A350-941 and A350-1041 aeroplanes. It addresses the inspection and replacement of washers installed on engine mount primary pins and thrust links to prevent potential engine mount pin disengagement. The directive applies specifically to certain manufacturer serial numbers and references Airbus Alert Operators Transmission A71P016-19 for detailed instructions.
What changed
This new airworthiness directive introduces a one-time inspection requirement for washers on front and rear engine mount primary pins and thrust link pins of both engines on affected Airbus A350 models. It mandates replacement of any incorrect washers found and requires reporting inspection results to Airbus. The directive also provides procedures for contacting Airbus if pins are found axially moved during inspection.
Why it matters
This directive is critical for aviation professionals because incorrect washers on engine mount pins could lead to pin disengagement and potential in-flight engine detachment, posing a serious safety risk. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and prevent reduced control of the aeroplane. Timely inspections and corrective actions help mitigate risks associated with engine mount failures.
