572744-28 – Parker Aerospace Fuel Filter Element Assembly

Available now on the Airparts.aero Marketplace.

The Parker Aerospace 572744-28 is a genuine OEM, flight-critical fuel filter element assembly, engineered to provide the highest level of contamination control for aircraft fuel systems. This component is indispensable for protecting sensitive downstream fuel system components, such as Fuel Control Units (FCUs), fuel pumps, and fuel nozzles/injectors, from microscopic particulate matter and water contamination present in aviation fuels. Its function is absolutely essential for ensuring reliable engine operation and preventing catastrophic engine power loss or damage due to fuel system contamination.

Manufactured by Parker Hannifin's Aerospace Filtration Division, this element utilizes advanced filtration media technology to achieve superior particle capture efficiency, high dirt-holding capacity, and low differential pressure across the element. Its robust construction ensures structural integrity under the high flow rates, pressure cycles, and vibration inherent in aircraft fuel systems. As a certified OEM component, the 572744-28 guarantees the performance and reliability required for flight safety.

Key Features

• Genuine Parker Aerospace OEM Part: Ensures correct fit, filtration performance, and material compatibility as specified by the airframe or engine manufacturer.

• High-Efficiency Filtration Media: Typically utilizes Parker's proprietary synthetic Micropleat™ media or equivalent advanced materials for exceptional particle capture efficiency across a wide range of micron sizes.

• Superior Dirt-Holding Capacity (DHC): The deeply pleated media design maximizes the effective filtration surface area, allowing the element to retain a large volume of contaminants before requiring replacement.

• Robust Structural Integrity: Features a strong core tube and high-strength end caps to prevent media collapse under high differential pressure or flow surge conditions.

• Fuel Compatibility: Engineered with materials fully compatible with common aviation fuels (Jet A, Jet A-1, Avgas) and additives.

• Low Differential Pressure: Designed for minimal flow restriction ($\Delta P$) across the element, optimizing fuel system performance and efficiency.

Why Choose 572744-28?

Choosing the genuine Parker 572744-28 is a critical decision for ensuring the safety and reliability of your aircraft's fuel system and engine. Clean fuel is paramount for turbine engine operation. Using non-certified or "will-fit" filter elements introduces significant risks, including poor filtration efficiency (allowing damaging particles downstream), low dirt-holding capacity (leading to premature clogging and bypass), media migration (shedding filter material into the fuel), or structural collapse under pressure. Any of these failures can lead to fuel starvation, FCU malfunction, or catastrophic engine damage. The genuine Parker OEM filter element guarantees the certified performance and quality required for this flight-critical application.

The performance of a high-efficiency fuel filter element like the 572744-28 is technically quantified by its Beta Ratio ($\beta_x(c)$), determined through multi-pass testing according to standards like ISO 16889. This ratio represents the number of particles upstream of a given size 'x' (in microns, measured at a specific concentration 'c') divided by the number of particles downstream of that same size. A rating of $\beta_{10(c)} = 5000$, for example, indicates that for every 5000 particles 10 microns or larger challenging the filter, only one passes through, yielding a 99.98% particle capture efficiency for that size. Parker's advanced synthetic Micropleat™ media utilizes a multi-layer, depth-filtration structure composed of fine microfiberglass filaments. This design creates a tortuous path that captures contaminants throughout the media's depth, not just on the surface. This maximizes the element's Dirt Holding Capacity (DHC)—the total mass of contaminant it can retain before reaching a specified terminal pressure drop—while maintaining low initial flow restriction ($\Delta P$). High Beta Ratios and high DHC are critical for protecting the extremely fine tolerances (often sub-micron) found in modern Fuel Control Unit servo-valves and fuel injectors from silting (clogging by fine particles) and erosive wear.

Note: This is a flight-critical fuel system component. It is a life-limited item and MUST be replaced at the intervals specified in the aircraft maintenance manual (AMM) or based on differential pressure indications, whichever occurs first. During replacement, extreme cleanliness must be observed to prevent contaminating the fuel system downstream of the filter. Ensure the correct installation orientation and proper sealing (replace housing seals if required). A leak check must be performed after installation. Installation must be performed by a certified A&P mechanic.
