EASA SIB 2018-12R1: Post De-Icing/Anti-Icing Checks

What to do

Air operators should review and update their de-icing procedures to align with the latest guidance in EASA SIB 2018-12R1, ensure personnel training and competency in post de-icing checks, and allow adequate time and visibility conditions for these checks. Operators should also communicate these recommendations to contracted ground service providers and verify compliance during audits. National Competent Authorities should incorporate these recommendations into their oversight programs. No mandatory compliance deadlines are specified as the bulletin provides non-mandatory recommendations.

Summary

EASA Safety Information Bulletin 2018-12R1 is a revised guidance document addressing post de-icing and anti-icing checks for aircraft during ground operations. It applies to air operators and National Competent Authorities and emphasizes the importance of thorough contamination checks after de-icing procedures to ensure safe aircraft dispatch. The bulletin references standards such as SAE AS6285 and Commission Regulation (EU) No 965/2012 but does not target specific aircraft types or engine models.

What changed

EASA SIB 2018-12R1 revises the original SIB 2018-12 issued in July 2018 by removing references to the withdrawn EASA SIB 2017-11 and incorporating its content into the updated guidance material GM3 CAT.OP.MPA.250. It clarifies the procedures for conducting post de-icing checks, including the option to perform these checks either separately or incorporated within the de-icing operation, and highlights operational considerations such as visibility and timing for effective checks.

Why it matters

This bulletin matters because improper post de-icing checks have been linked to safety incidents involving contaminated aircraft surfaces, which can compromise flight safety. For operators, maintenance organizations, and compliance teams, following these recommendations helps ensure that aircraft are free of ice and contaminants before departure, reducing the risk of accidents related to inadequate ground de-icing. It also supports regulatory compliance with EU aviation safety rules.
