EASA SD SD-2025-01
Replacement of certain Rockwell Collins SBAS receivers on aeroplanes conducting LPV200 approaches in EGNOS SoL service area
Summary
EASA Safety Directive 2025-01 mandates the replacement of certain Rockwell Collins Satellite Based Augmentation Systems (SBAS) receivers installed on various aircraft conducting LPV-200 approaches within the EGNOS Safety of Life service area. Affected aircraft include models from Airbus such as the A318, A319, A320, A321, A330, A350, and A380, as well as Bombardier, Dassault Falcon series, Embraer EMB-550, Gulfstream G150, G280, G200, and others equipped with GPS-4000S, GLU-2100, GLUS-2100, and GLUS-2100A receivers. This directive addresses a safety concern related to the integrity monitoring of GNSS signals used for precision approaches.
What Changed
This new Safety Directive introduces a mandatory requirement for operators to replace affected Rockwell Collins SBAS receivers that do not comply with RTCA DO-229 standards due to a non-compliance issue with integrity message processing. It aligns with EASA Airworthiness Directive 2025-0088 by enforcing the replacement of these receivers within two years and prohibiting the installation of affected units. The directive applies specifically to third country operators authorized by EASA performing commercial air transport operations in the EGNOS SoL service area.
Why It Matters
The directive is critical because the affected SBAS receivers may fail to alert flight crews of compromised GNSS position integrity during LPV-200 approaches, potentially undermining flight safety. For operators and maintenance organizations, this means ensuring compliance to avoid operating with non-conforming equipment that could invalidate the approved safety conditions of satellite-based augmentation systems. Compliance teams must track and implement these changes to maintain regulatory approval and operational safety within European airspace.
What To Do
Affected aircraft operators must comply with the requirements of EASA Airworthiness Directive 2025-0088 starting from 30 April 2025, which includes replacing the affected Rockwell Collins SBAS receivers within two years. Operators are prohibited from installing or reinstalling any affected receivers after the effective date.
