EASA AD 2021-0111R1
Windows — Windshields — Inspection
Summary
EASA Airworthiness Directive 2021-0111R1 is a regulatory update addressing inspection requirements for windshields installed on Airbus A318, A319, A320, and A321 aeroplanes. It mandates detailed and electrical test inspections of specific affected windshield parts to ensure structural integrity and prevent in-flight windshield failure. The directive applies to all serial numbers of the listed Airbus models and specifies affected part numbers grouped by risk level.
What Changed
This revision of EASA AD 2021-0111 removes flight hour (FH) references from compliance times, basing inspection intervals solely on calendar time and flight cycles (FC). It clarifies inspection intervals and conditions for different groups of affected windshield parts and updates compliance requirements accordingly.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent windshield failure that could lead to rapid depressurization and increased pilot workload. Compliance ensures continued airworthiness and safety of Airbus A318 to A321 aircraft by detecting and correcting windshield defects before they pose a hazard. It also affects maintenance planning and parts management due to the detailed inspection and replacement requirements.
What To Do
Operators must perform detailed inspections and electrical test measurements on affected windshield parts within specified intervals, starting no later than 4 months or 750 flight cycles after 6 May 2021 or since first installation. Defective parts must be replaced before next flight, and repetitive inspections must continue until affected parts are replaced with non-affected serviceable parts. Installation of only serviceable windshields is permitted from 6 May 2021 onward.
