EASA SIB BEA-2024-08: Hydraulic Power - Inspection of Hydraulic Tube and Supports

What to do

Operators of EMBRAER ERJ 190-300 and ERJ 190-400 aircraft should perform a General Visual Inspection of hydraulic tube supports and clamps for breakage and pre-load conditions following Embraer Service Bulletin No. 190E2-29-0004. Any broken supports must be replaced with parts of the same part number, and proper torque procedures must be applied to hydraulic fittings. No mandatory compliance deadline is specified, but timely inspection is recommended.

Summary

The Special Airworthiness Bulletin BEA 2024-08 is an informative document addressing the inspection of hydraulic tubes and supports on EMBRAER S.A. ERJ 190-300 and ERJ 190-400 aircraft models. It alerts the civil aviation community to reported broken hydraulic line supports in the wing region, caused by incorrect torque application during production. The bulletin provides guidance but does not impose mandatory requirements or an Airworthiness Directive.

What changed

BEA 2024-08 introduces recommendations for inspecting hydraulic tube supports and correcting any breakages found, based on Embraer Service Bulletin No. 190E2-29-0004 dated February 29, 2024. It also outlines revised installation procedures and maintenance manual updates to prevent recurrence of the issue. The bulletin includes detailed inspection and torque procedures to ensure proper hydraulic tube support integrity.

Why it matters

This bulletin is important for operators, maintenance organizations, and compliance teams because broken hydraulic tube supports can compromise hydraulic system reliability, potentially affecting aircraft safety. Early detection and correction help maintain airworthiness and prevent hydraulic system failures. The guidance supports consistent maintenance practices and reduces the risk of in-service hydraulic issues related to production torque errors.
