Wings - Outer-Wing Front Lower Panel - Inspection
Summary
Airworthiness Directive 2017-322-04 issued by the Federal Air Transport Agency of the Russian Federation mandates inspections on the RRJ-95 aircraft, specifically targeting the outer-wing front lower panel between ribs 4 and 6. The directive applies to RRJ-95 aircraft with manufacturer serial number 95022 and above. It requires detailed inspections at specified flight cycle and flight hour intervals to ensure structural integrity.
What Changed
This new Airworthiness Directive introduces mandatory inspection procedures for the outer-wing front lower panel of RRJ-95 aircraft. It requires operators to perform detailed inspections during every 8-day maintenance check and additional special inspections starting at 5800 flight cycles or 8700 flight hours. The directive also mandates amendments to the aircraft's operational technical documentation (ICA) to reflect these inspection requirements.
Why It Matters
This directive is critical for maintaining the structural safety of RRJ-95 aircraft by identifying potential issues in the outer-wing front lower panel early. Compliance ensures continued airworthiness and prevents possible in-service failures. Operators, maintenance organizations, and compliance teams must integrate these inspections into their maintenance schedules to meet regulatory requirements and avoid grounding.
What To Do
Operators of RRJ-95 aircraft with MSN 95022 and above must conduct detailed inspections of the outer-wing front lower panel every 8 days. Starting at 5800 flight cycles or 8700 flight hours, additional special inspections must be performed according to specified AMM and NDTM procedures. Aircraft with 5800 flight cycles or 8700 flight hours and above must complete special inspections within 14 calendar days of the directive's effective date. The aircraft design organization must update the ICA accordingly, after which this directive will be rescinded.
