EASA AD 2018-0050-E
SUPERSEDED BY EASA AD 2019-0239-E
Summary
EASA Airworthiness Directive 2018-0050-E is an emergency directive addressing the XA41 and XA42 aeroplanes manufactured by XtremeAir GmbH. It mandates inspections of engine mounts with part number XA42-7120-151 due to detected cracks that could lead to engine detachment and loss of control. The directive requires repetitive inspections and replacement of affected parts if cracks are found.
What Changed
This directive introduces mandatory repetitive inspections of the engine mount diagonal strut on XA41 and XA42 aeroplanes. It also requires immediate replacement of the engine mount if cracks are detected during inspections. The directive is an interim safety measure pending further action.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent potential in-flight engine detachment caused by structural failure of the engine mount. Compliance ensures continued airworthiness and safety of the affected aircraft, reducing risk to crew, passengers, and people on the ground. It also affects parts installation procedures and maintenance planning.
What To Do
Operators must inspect the affected engine mounts before the next acrobatic flight after 5 March 2018 or before 50 flight hours since installation, whichever is later, and then every 10 acrobatic flights. If cracks are found, the engine mount must be replaced before further flight. Installation of new or inspected parts is allowed only if they meet the inspection requirements.
