EASA AD 2013-0104R3
Flight Controls — Flap Actuator — Inspection / Replacement / Modification
Summary
EASA Airworthiness Directive 2013-0104R3 is an update addressing the inspection, replacement, and modification of flap actuators on DAHER AEROSPACE TBM 700 aeroplanes. It applies to all TBM 700 aircraft except those with the MOD 70-0777-27 modification incorporated during production. The directive focuses on preventing loss of flap control due to wear and grease contamination in flap actuator drive nuts.
What Changed
This revision adds an optional modification as a terminating action to the repetitive inspections and cleaning requirements. It updates the service bulletin to Revision 3, which provides instructions for the flap actuator drive nut replacement. The applicability is narrowed to exclude aircraft with the MOD 70-0777-27 modification, and inspection intervals have been extended based on improved design and analysis.
Why It Matters
This directive is critical for maintaining safe flap control on TBM 700 aircraft by ensuring timely detection and correction of wear in flap actuator components. Operators and maintenance organizations must comply to avoid potential flap control loss, which could compromise aircraft handling and safety. The updated compliance intervals and terminating modification option help optimize maintenance efforts and reduce operational disruptions.
What To Do
Operators must clean and lubricate the left-hand and right-hand inner flap actuators within 400 flight hours or 12 months after installation and repeat at these intervals. They must inspect the actuator play within specified compliance times and intervals, and perform corrective actions if discrepancies are found. Incorporating the Revision 3 modification of the flap actuator drive nut terminates the need for repetitive inspections, provided no affected parts remain installed.
