Expert Tips for Aircraft Towbar Maintenance & Best Practices

Aircraft towbars are a core category of ground support equipment (GSE) that are used to facilitate controlled aircraft movement during ground towing operations. As these tools are routinely subjected to repeated mechanical loading, environmental exposure, and frequent handling by ground crews, structured maintenance practices can significantly influence service life and operational availability. In this blog, we will outline key pre-use inspection checks for aircraft towbars, identify key sources for replacement and service components, and examine how storage and handling practices can affect long-term maintenance outcomes.

What Are Common Types of Aircraft Towbars?

Aircraft towbars are available in several established configurations that reflect differences in aircraft size, nose landing gear geometry, and ground handling requirements, with core types including:

Head-Specific Towbars: These towbars use a fixed towhead that is designed to interface with a specific aircraft’s nose landing gear geometry, providing consistent alignment and secure engagement for designated aircraft models.
Universal Towbars: Universal towbars feature interchangeable towheads or adjustable interface assemblies that allow a single bar to support multiple aircraft types, making them ideal for operations that handle mixed or diverse fleets.
Shear-Pin Towbars: Shear-pin towbars incorporate engineered breakaway pins that are designed to fail at defined load thresholds, reducing the risk of structural damage to aircraft nose landing gear components during many abnormal or excessive towing loads.

What Visual and Functional Checks Are Commonly Performed on Aircraft Towbars?

Ground crews typically perform a concise set of visual and functional checks before connecting or using a towbar to confirm that it appears serviceable for intended towing operations.

Structural Condition: Before connecting a towbar, operators should visually inspect the main body for cracks, bends, deformations, or abnormal wear that could indicate structural damage affecting safe towing performance.
Towhead Engagement: During setup, the towhead interface should be checked for proper alignment with the aircraft’s nose landing gear to confirm that it seats correctly without looseness.
Attachment Hardware: Prior to aircraft movement, retaining mechanisms should be visually confirmed as present and secured to reduce the risk of unintended disengagement during towing operations.
General Cleanliness: Before use, accumulated debris, corrosion, or surface contamination should be noted, as these conditions can restrict articulation or even affect overall towbar handling.

What Manufacturers Offer Aircraft Towbar Replacement and Service Parts?

Aircraft towbar maintenance typically depends on access to replacement components that are compatible with specific aircraft nose landing gear interfaces. To obtain these products, operators and ground support teams commonly source from established ground support equipment (GSE) manufacturers, including:

Tronair: Tronair is widely recognized for producing universal and aircraft-specific towbar systems, along with various replacement components that support continued ground handling operations.
TLD: TLD supplies a broad range of ground support equipment, offering towbar assemblies and service parts that are deployed across commercial, cargo, and military aviation environments.
JBT AeroTech: JBT AeroTech supports aircraft towing operations through a range of ground support solutions, including towbar-related components that complement its wider aircraft handling and ramp equipment offerings.
Langa Industrial: Langa Industrial specializes in aircraft towing solutions, providing replacement towbar parts engineered to maintain compatibility across multiple aircraft types and fleet configurations.
Malabar International: Malabar International offers aircraft towbars and associated service components commonly utilized for regional, business, and military aircraft ground handling applications.

How Do Storage and Handling Practices Influence Aircraft Towbar Maintenance Needs?

Although aircraft towbars are designed for repeated ground use, the way they are stored and handled between towing operations can influence long-term inspection frequency and maintenance planning.

Environmental Exposure: Towbars that are stored outdoors for extended periods may be more susceptible to corrosion or coating degradation due to contaminants commonly present on ramp surfaces.
Improper Storage Positioning: Storing towbars directly on the ground or without adequate support can introduce localized loading, increase the risk of bending, or place unnecessary stress on attachment points.
Handling and Transport Practices: Dragging, dropping, or lifting towbars without appropriate handling methods can introduce impact damage or cumulative structural stress.
Shared Equipment Use: Towbars that are routinely transferred between ramps, facilities, or multiple aircraft types often experience higher handling frequency, which can contribute to accelerated wear.
