EASA SIB CE-12-30: Eclipse EA500 Aeroplanes — Wing Main Spar-to-Fuselage Attachment Lugs

What to do

Operators of Eclipse EA500 aircraft should inspect the wing main spar and fuselage attach lugs for corrosion and damage at the next 300-hour or 24-month inspection interval, following the procedures in Eclipse Mandatory Service Bulletins 500-57-011 Revision B and 500-53-008 Revision B. They should also modify the lower wing-to-body fairings to improve drainage as specified. These actions are recommended to maintain aircraft safety and structural integrity.

Summary

The Special Airworthiness Information Bulletin SAIB: CE-12-30 is an FAA informational bulletin addressing corrosion concerns on the wing main spar and fuselage attachment lugs of Eclipse Aerospace EA500 model series aircraft. It provides guidance for inspection and maintenance to registered owners and operators of these aircraft. The bulletin highlights corrosion issues without mandating regulatory action but encourages compliance with Eclipse Aerospace's mandatory service bulletins.

What changed

This bulletin introduces awareness of corrosion found on the wing main spar and fuselage attach lugs of Eclipse EA500 aircraft and recommends inspections and modifications. It references Eclipse Aerospace Mandatory Service Bulletins 500-57-011 Revision B and 500-53-008 Revision B, which provide detailed inspection, corrosion removal, protection procedures, and fairing modifications to improve drainage.

Why it matters

This information is critical for aviation professionals to maintain the structural integrity and safety margins of Eclipse EA500 aircraft. Early detection and correction of corrosion can prevent degradation of key wing-to-fuselage attachment points, ensuring continued airworthiness and reducing the risk of costly repairs or operational disruptions. Compliance teams and maintenance organizations benefit from clear guidance to address this potential issue proactively.
