EASA AD 26-106
Landing Gear – Main Landing Gear Barrel – Inspection
Summary
EASA Airworthiness Directive Proposal PAD No. 26-106 addresses the inspection of the main landing gear barrels on DAHER Aircraft SAS TBM 700 aeroplanes. The directive targets specific serial numbers of main landing gear barrels installed on these aircraft to detect potential cracks due to manufacturing non-conformities. It applies to all TBM 700 aeroplanes regardless of serial number and requires inspection and possible replacement of affected parts.
What Changed
This new proposed airworthiness directive introduces a one-time inspection requirement for the main landing gear barrels on TBM 700 aeroplanes to identify cracks caused by forging joint line defects. It establishes compliance timelines and corrective actions including replacement of cracked parts. The directive also clarifies installation rules for affected parts post-inspection.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to landing gear collapse during takeoff or landing, potentially compromising aircraft structural integrity. Operators and maintenance organizations must ensure timely inspections and replacements to maintain airworthiness and regulatory compliance. Failure to comply could result in unsafe flight conditions and regulatory penalties.
What To Do
Operators of DAHER TBM 700 aeroplanes with affected main landing gear barrels must perform a one-time inspection within 3 months of the directive's effective date or within 12 months or 200 landings since the last annual inspection, whichever is later. If cracks are found, the affected parts must be replaced before the next flight. Installation of affected parts is only allowed if they are serviceable as defined by the directive.
