EASA AD 2006-0085R3
Landing Gear — Main Landing Gear Shock Strut Cylinder — Inspection / Replacement / Modification
Summary
EASA Airworthiness Directive 2006-0085R3 addresses inspection, replacement, and modification requirements for the main landing gear shock strut cylinder on DAHER Aerospace TBM 700 aeroplanes, specifically serial numbers 1 through 638 and 687. This directive mandates repetitive special detail inspections for cracks in specified main landing gear parts and allows for installation of reinforced landing gear as a terminating action. It applies to main landing gear parts with certain part numbers and aims to prevent landing gear collapse due to fatigue cracks.
What Changed
EASA Airworthiness Directive 2006-0085R3 revises the previous version by introducing clear definitions of 'affected part' and 'serviceable part,' including additional part numbers of reinforced main landing gear accepted as optional terminating actions for repetitive inspections. It also updates compliance instructions to incorporate the latest DAHER service bulletin revisions and maintenance manual updates. The applicability was refined by excluding certain serial numbers and allowing installation of new reinforced parts.
Why It Matters
This directive is critical for aviation professionals to ensure the structural integrity and safety of TBM 700 aircraft during takeoff and landing by preventing main landing gear failures. Operators and maintenance organizations must comply with inspection intervals and corrective actions to avoid potential gear collapse. Compliance teams need to track affected serial numbers and part numbers to maintain airworthiness and avoid regulatory violations.
What To Do
Operators of DAHER Aerospace TBM 700 aeroplanes with affected main landing gear must perform initial and repetitive special detail inspections within specified landing cycle intervals, starting as early as 25 landings after the directive's original issue date depending on accumulated landings. If cracks are detected, parts must be removed and inspected with dye or fluorescent penetrant methods, and repaired or replaced following DAHER-approved instructions before further flight. Installation of reinforced landing gear parts per DAHER service bulletins or maintenance manuals can terminate the inspection requirements.
