What to do
Operators must modify the affected holes on stringer attachments at ribs 2 to 7 by oversizing them according to Airbus Service Bulletin A320-57-1208 within specified flight hour or flight cycle windows. Inspections including Eddy Current Inspections must be performed during modification. If damage is found, corrective actions approved by Airbus must be implemented before further flight. Additionally, operators who previously completed the original issue of SB A320-57-1208 must contact Airbus within 12 months of the effective date for further instructions.
Summary
EASA Airworthiness Directive 2021-0167 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A318, A319, A320, and A321 aeroplanes. It mandates inspection and modification of the stringer attachments at wing ribs 2 to 7 to address potential structural integrity issues. The directive applies to various serial numbers and configurations except those already modified by specific Airbus modifications or service bulletins.
What changed
This directive supersedes EASA AD 2017-0117 and introduces updated compliance times for certain aircraft configurations. It also includes additional modification requirements for aeroplanes previously modified according to Airbus Service Bulletin A320-57-1208. The directive expands the scope to cover new affected configurations, including those operating in the Commonwealth of Independent States (CIS).
Why it matters
This directive is critical for maintaining the structural integrity of Airbus A320 family wings, especially concerning fatigue damage and service life extension. Operators and maintenance organizations must comply to ensure continued airworthiness and safe operation up to the limit of validity. Failure to comply may result in unsafe conditions affecting wing structure and potential operational restrictions.
