What to do
Operators must perform a detailed visual inspection of the specified wing areas within 12 months after 2017-12-21 or within 48 months or 6,000 flight cycles since first flight, whichever is later. Inspections must be repeated every 48 months or 6,000 flight cycles thereafter. Any detected cracks require contacting ATR for approved repair instructions and completing repairs before further flight. Inspection results must be reported to ATR within 30 days after each inspection.
Summary
EASA Airworthiness Directive 2017-0244 is an inspection directive applicable to ATR 42-200, ATR 42-300, ATR 42-320, ATR 42-400, and ATR 42-500 aeroplanes. It mandates repetitive detailed visual inspections of the outer wing box upper rib feet and upper skin between ribs 24 and 29 to detect cracks that could compromise structural integrity. The directive includes requirements for corrective repairs if discrepancies are found.
What changed
This directive supersedes the previous DGAC France AD F-2004-191 and introduces repetitive inspections rather than a one-time inspection. It also requires operators to report inspection results to ATR and follow updated service bulletin ATR42-57-0074 for inspection procedures and repair instructions.
Why it matters
This directive is critical for maintaining the structural integrity of affected ATR 42 aircraft wings by ensuring early detection and repair of cracks. It impacts operators, maintenance organizations, and compliance teams by establishing mandatory inspection intervals and reporting requirements to prevent potential safety risks.
