2 Critical Heavy Maintenance Services to Elevate Your Aircraft’s Performance

What is Heavy Maintenance?

Definition and Significance

Heavy maintenance refers to the comprehensive and detailed overhaul, repair, and modification of an aircraft or its major components. Unlike routine maintenance or minor repairs, heavy maintenance involves extensive work, often requiring the partial or complete disassembly of the aircraft.

This type of maintenance is generally conducted at specific intervals determined by flight hours, calendar time, or cycles, and is critical to the aircraft’s long-term performance, safety, and regulatory compliance.

Categories of Heavy Maintenance

C-Checks

C-Checks are extensive inspections that delve into a significant portion of the aircraft’s components and systems. They typically involve detailed examinations, adjustments, repairs, and replacements. C-Checks are usually conducted every 20 to 24 months.

D-Checks

D-Checks, or heavy maintenance visits (HMV), are the most comprehensive and time-consuming maintenance activities. Conducted roughly every six to ten years, they require the complete disassembly of the aircraft. Virtually every part is inspected, repaired, or replaced as needed.

Components and Processes Involved in Heavy Maintenance

Structural Inspections and Repairs

Heavy maintenance includes a thorough inspection of the aircraft’s structural components, such as the fuselage, wings, tail, and landing gear. Any corrosion, cracks, or damage is meticulously repaired or replaced.

Systems Overhaul

Major systems, including hydraulic, electrical, avionic, and environmental systems, are thoroughly inspected, overhauled, and calibrated.

Engine Maintenance

Heavy maintenance often involves the complete removal and overhaul of engines. This includes detailed inspections, repairs, replacements, and performance testing.

Interior Refurbishment

The aircraft’s interior may be refurbished or reconfigured during heavy maintenance, improving passenger comfort and meeting specific airline requirements.

Painting and Aesthetics

Aircraft may be repainted, and exterior surfaces treated to enhance appearance and protect against environmental factors.

Compliance and Upgrades

Compliance with regulatory requirements and implementation of mandated modifications or upgrades is an essential aspect of heavy maintenance.
