Available now on the Airparts.aero Marketplace.

Overview

The Meggitt 5007897-3 is a genuine OEM, flight-critical main wheel assembly, engineered specifically for the demanding operational environment of the McDonnell Douglas MD-80 series of commercial airliners. This is not a simple wheel; it is a high-strength, forged aluminum structural component designed by Meggitt Aircraft Braking Systems (now part of Parker Meggitt), a world leader in aerospace wheel and brake technology. The 5007897-3 is designed to withstand the immense static and dynamic loads of a transport-category aircraft, including the extreme forces of high-speed takeoffs, landings, and maximum-energy braking events.

Key Features

• High-Strength Forged Aluminum Construction: The wheel halves are forged from a single billet of high-grade, aerospace aluminum alloy. The forging process creates a dense, oriented grain structure that provides superior strength, durability, and resistance to fatigue cracking compared to cast wheels.
• Two-Piece Split-Rim Design: Comprised of two halves (inboard and outboard) that are secured together with high-strength through-bolts. This design allows for easier and faster mounting and dismounting of the large, high-pressure tires used on airliners.
• Integrated Fusible Plugs: The wheel hub is designed with ports for the installation of multiple fusible plugs. These are critical, thermally-activated safety devices that are designed to melt and safely deflate the tire in an extreme overheat condition (such as a locked or dragging brake), preventing a catastrophic tire and wheel explosion.
• Engineered for Multi-Disc Brakes: Precision-machined with the keyways and structural integrity required to house and support the massive, multi-disc steel brake stack, and to transfer the immense braking torque from the brakes to the tire.
• Genuine OEM System: As a genuine OEM component from the original aircraft supply chain, it guarantees perfect fitment, certified material strength, and full conformance to the rigorous testing and quality standards of the aircraft's original Type Certificate.

• Primary Aircraft Models:
  • McDonnell Douglas MD-80, MD-81, MD-82, MD-83, MD-88

Applications

The 5007897-3 is a flight-critical assembly with several vital roles:

• Primary Wheel Installation: Serves as the primary rotating assembly that holds the high-pressure tire and interfaces with the multi-disc brake system.
• Landing & Ground Operations: Designed to bear the full weight of the aircraft (up to 160,000 lbs MTOW for an MD-83) and withstand the severe spin-up and side-load forces of landing at high speeds.
• Mandatory Overhaul/Inspection Item: Wheels on transport-category aircraft are life-limited components that require periodic removal and complete overhaul, including non-destructive testing (NDT) for cracks.

Why Choose 5007897-3?

The failure of a main wheel assembly on an airliner during takeoff or landing can be catastrophic. The Meggitt 5007897-3 is the genuine, certified component that was tested and approved by the aircraft manufacturer for this purpose. Using a genuine OEM wheel assembly is the only way to ensure you are installing a part with a known, traceable manufacturing and service history, free from hidden defects, and made from the correct, certified materials. For a component so fundamental to the safety of every flight, there is no substitute for the proven quality and airworthiness of a genuine OEM wheel.

The 5007897-3's forged aluminum construction provides a superior grain structure compared to casting. The forging process subjects a solid billet of aluminum alloy to immense pressure, forcing the material's grain to align with the shape of the wheel. This eliminates the porosity and random grain boundaries found in cast parts, resulting in a component with significantly higher tensile strength, ductility, and resistance to fatigue crack initiation and propagation. This enhanced material property is essential for a component like a main wheel, which must endure the stress of thousands of landings, each one representing a significant fatigue cycle. The integrated fusible plugs are a critical, final layer of safety, designed to prevent a tire explosion by thermally activating well below the temperature at which the aluminum wheel itself would begin to lose its structural integrity.

Note: This is a flight-critical, serialized, and life-limited aircraft assembly. Installation, servicing, and all maintenance actions must be performed by certified AME or A&P mechanics holding the appropriate ratings and in strict accordance with the current McDonnell Douglas / Boeing maintenance manual. Tire mounting and inflation on a split-rim wheel must be performed in a safety cage.
