NTSB Confirms CL604 Dual-Engine Failure From Saltwater Corrosion — Coastal Business Jet CF34 Engine Inspection Protocol Faces Full Review
Analysis
NTSB on April 23 released final report on Hop-A-Jet CL604 crash at Naples, Florida, confirming widespread saltwater corrosion in GE CF34 engine variable geometry (VG) system, causing both engines to fail simultaneously. Key finding: maintenance personnel had noted engine issues pre-event and conducted pressure tests but failed to detect the corrosion. Hop-A-Jet acknowledged the report as 'accurate assessment.' AviGo data shows Hop-A-Jet Q1 2026 operations active, with fleet ~10 stable. The accident carries major warning significance for all coastal/high-humidity operating CL604/CL605 fleets' corrosion inspection protocols. Confidence ★★★ (NTSB report + AviGo operating data dual cross-verification).
