EASA AD 22-001R1
Fuselage — Supporting Struts Rod Ends at Frame 58 — Inspection
Summary
EASA Airworthiness Directive PAD No. 22-001R1 is a proposed directive addressing inspection requirements for supporting struts rod ends at frame 58 on Irkut Corporation JSC RRJ-95B aeroplanes. It targets specific part numbers T7.92.0671.230.000.70 and T7.92.0671.255.000.70 installed on these aircraft. The directive mandates repetitive inspections to detect fatigue fractures that could compromise structural integrity.
What Changed
This proposed directive introduces repetitive detailed visual inspections at revised compliance times and reduced intervals compared to the previous Russian AD 2020-FATA-01020A-08, which EASA did not adopt. It also updates and clarifies the definition of serviceable parts and specifies inspection and corrective action procedures.
Why It Matters
This directive is critical for aviation professionals to prevent potential failure of primary load-carrying structures due to fatigue fractures in the supporting struts. Operators and maintenance organizations must comply to ensure continued airworthiness and avoid possible loss of control of the aircraft. It impacts maintenance planning and part replacement strategies for RRJ-95B operators.
What To Do
Operators must perform initial and repetitive inspections of the affected rod ends before exceeding specified flight cycle thresholds and at intervals not exceeding 250 to 750 flight hours or 250 to 500 flight cycles depending on the part's usage. Any detected damage requires contacting Irkut Corporation for approved replacement instructions before further flight. Only serviceable parts, as defined, may be installed from the effective date, and inspections must continue even after part replacement.
