EASA AD 2018-0138
Powerplant — Forward Engine Mount Shackle Assembly — Inspection
Summary
EASA Airworthiness Directive 2018-0138 is an official safety directive addressing Airbus A380-861 aeroplanes equipped with Engine Alliance GP7200 engines. It mandates a one-time special detailed inspection of the forward engine mount shackle assemblies and safety tabs to detect potential quality defects that could lead to engine loss in flight. The directive provides inspection instructions based on Airbus Service Bulletin A380-71-8015.
What Changed
This new directive introduces a mandatory inspection requirement for the forward engine mount shackle assemblies on Airbus A380 aircraft to identify and correct any defects related to improperly engaged safety tabs. It requires operators to perform inspections within specified flight cycle thresholds and carry out corrective repairs if discrepancies are found.
Why It Matters
This directive is critical for aviation professionals because undetected defects in the forward engine mount shackle assembly could result in in-flight engine separation, posing serious safety risks to the aircraft and people on the ground. Compliance ensures continued airworthiness and prevents potential accidents, making it essential for operators, maintenance organizations, and regulatory compliance teams to address promptly.
What To Do
Operators must perform a one-time special detailed inspection of the forward engine mount shackle assemblies within the compliance times specified based on flight cycles, either before exceeding 3,800 flight cycles or within 300 flight cycles after the directive's effective date. If any discrepancies are found, corrective actions including engine removal and repair must be completed within the specified timeframes or before the next flight as directed by Airbus instructions.
