Wings - Lower Rear Panel of the Center Wing - Inspection
Summary
Airworthiness Directive 2018-322-07 from the Federal Air Transport Agency of the Russian Federation mandates inspection of the lower rear panel of the center wing on RRJ-95 aircraft. This directive addresses detected cracks in the rib of the left-hand longitudinal beam part number T7.92.1000.006.000.73. It requires a one-time detailed inspection during the next periodic maintenance and outlines reporting and follow-up procedures.
What Changed
This new Airworthiness Directive introduces mandatory one-time inspections of the edges of both left-hand and right-hand longitudinal beams of the lower rear panel of the center wing on RRJ-95 aircraft. It specifies inspection intervals tied to flight hours and calendar days and requires reporting of any damage to the aircraft designer, JSC Sukhoi Civil Aircraft. Further actions depend on individual decisions from the aircraft designer based on inspection findings.
Why It Matters
This directive is critical for maintaining the structural integrity of the RRJ-95 aircraft by identifying potential cracks early, preventing possible structural failures. Operators and maintenance organizations must comply to ensure continued airworthiness and regulatory compliance. Timely inspections and reporting help mitigate safety risks and support informed maintenance decisions.
What To Do
Operators of RRJ-95 aircraft must perform a one-time detailed inspection of the specified lower rear panel areas during the next periodic maintenance, which occurs at multiples of 750 flight hours or 100 days, whichever comes first. Any detected damage must be reported to JSC Sukhoi Civil Aircraft and the Federal Air Transport Agency's Aircraft Continued Airworthiness Department. Follow-up actions will be based on instructions from the aircraft designer.
