EASA AD 2023-0082
Wings — Flap Track Support Fittings — Inspection
Summary
EASA Airworthiness Directive 2023-0082 is an airworthiness directive addressing the inspection of flap track support fittings on Airbus Defence and Space CN-235, CN-235-100, and CN-235-200 aeroplanes with manufacturer serial numbers up to 146. It mandates inspections to detect cracking in wing flap track lugs, which could lead to structural failure and reduced control of the aircraft. The directive applies specifically to wing flap track support fittings on both left-hand and right-hand sides.
What Changed
EASA Airworthiness Directive 2023-0082 supersedes the previous DGAC Spain AD No. 01/92 from 1992, reducing the applicability to aircraft with serial numbers up to 146 and introducing an optional terminating action through modification of the flap track fittings. It retains the requirement for repetitive inspections but provides updated inspection instructions and repair procedures through CASA Maintenance Instruction COM235-58 and Airbus Defence and Space Service Bulletin SB-235-57-15.
Why It Matters
This directive is critical for aviation professionals to prevent potential structural failures caused by cracking in flap track support fittings, especially for aircraft operating in highly corrosive environments. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. The directive also offers an option to terminate repetitive inspections by modifying the affected parts, which can reduce maintenance burden and improve operational efficiency.
What To Do
Operators of affected CN-235 series aeroplanes must inspect the wing flap track support fittings within the specified compliance times—either within 48 months or before the next flight depending on flight hours accumulated as of 14 January 1992—and repeat inspections every 12 months thereafter. If discrepancies are found, repairs must be performed using approved instructions before further flight. Alternatively, operators may modify the fittings according to the Airbus Defence and Space service bulletin to terminate the need for repetitive inspections.
