Tronair 99-9028-6000 – 12" Aircraft Wheel Chocks, Black with Orange Stripe

These chocks are finished in black with a bright orange stripe across the top for high visibility. The color contrast helps ground crew identify them quickly in low light or busy ramp environments, improving safety and reducing the risk of runway/run-up area interference.

They have a triangular profile with ridged edges to provide a stronger grip against both smooth and slightly uneven ramp surfaces. When correctly placed in front of and behind wheels, this shape helps lock the wheel in place, resisting movement due to taxiing, ground vibration, or wind.

The 99-9028-6000 is offered as a set of two individual chocks. Each one is used on either side of an aircraft tire – one in front, one behind – to immobilize the aircraft.

These chocks are widely compatible with many aircraft models, from small fixed-wing to large business jets and commercial aircraft. The product listing shows compatibility with a broad range of makes, including Airbus, Bombardier, Learjet, Gulfstream, and others. However, always verify wheel size and tire configuration with your aircraft maintenance manual before selecting any chock.

The NSN for the Tronair 99-9028-6000 chocks is 1730-01-462-0026. This number is helpful for military and government procurement, logistics, and ensuring correct cross-referencing.

These chocks are made from durable, high-impact materials (typically molded rubber or polyurethane composites), which resist cracking, weather, and oil exposure. Their sturdy build helps them withstand repeated contact with heavy wheels and ramp surfaces without deforming or losing effectiveness.

Place one chock immediately in front of a tire and one behind it, ensuring both are snug against the tire. Use both chocks even on slight inclines or ramp gradients. Proper placement prevents the aircraft from rolling in either direction, which is essential during boarding, maintenance, or fueling.

They include a rope connecting the pair, making them easy to carry together and less likely to be misplaced. Their size allows them to be stacked or placed on chock racks when not in use. The weight (≈20 lbs each) is manageable enough for technicians to move them comfortably.

Technicians should regularly check the chocks for cracks, flattened or worn bottom surfaces, or torn or frayed edges – especially in the ridged surfaces that contact the ground. Also, inspect the paint or stripe for fading or damage that could reduce visibility. Replacing worn chocks helps maintain safe immobilization of aircraft.

Yes, the materials and finishes used are rated to withstand outdoor exposure including sun, moisture, jet fuel, and standard ramp conditions. The visible stripe helps compensate for snow or low visibility. However, extremely cold or icy surfaces may reduce friction; always ensure contact surfaces are clean and free of slick substances when deploying chocks.
