Wide Body Aircraft
A twin aisle aircraft with a fuselage over 5 meters wide, typically used for medium to long haul flights.
WIDE BODY AIRCRAFT
Wide body aircraft engines operate under prolonged high thrust conditions, demanding rigorous and regular internal inspection.
Borescope inspections for these engines focus on early detection of fatigue, thermal degradation, and foreign object impact to ensure safe long range operations and compliance with extended-range twin-engine operational performance standards (ETOPS).
High Thrust & High Temperature Areas
Inspections prioritise zones subjected to extreme stress, such as HPT vanes/blades, combustor liners, and HPC stages. Conditions like blade creep, tip rub, hot section burning, and stress cracks are closely monitored using precision optics.
Engine Specific Protocols
Wide body engines require model-specific inspection paths and techniques. OEM guidance is followed precisely for access points, component limits, and defect classifications, ensuring findings are valid for airworthiness decisions and ETOPS compliance.
Digital Reporting for Fleet Wide Analysis
Collected data is archived by engine serial number and integrated into airline reliability programs. Trend analysis across large twin-aisle fleets (e.g., B777, A330, B787, B747, A350) supports predictive planning and minimises engine removals during long-haul rotations.

Inspection Planning & Operational Context
Wide body borescope inspections are conducted during scheduled heavy checks (e.g., C or IL), post-event diagnostics, or pre-ETOPS validation.
Due to the size and complexity of engines, inspections are often coordinated with engine health monitoring systems (EHM) to validate performance alerts.
Findings directly influence time-on-wing estimates, spare engine allocation, and maintenance reserves, making borescope data a critical element of wide-body fleet management.
