Boeing 747-300

Jet Brella Boeing 747‑400 Engine Covers

Jet Brella’s precision-crafted engine cover system for the Boeing 747-400 is engineered to accommodate the aircraft’s four-engine setup, providing full inlet and exhaust coverage for engines typically used on this variant, such as the Pratt & Whitney PW4056, General Electric CF6-80C2B1F, and Rolls-Royce RB211-524G/H. Ideal for use during extended storage, layovers, or maintenance periods, these inlet covers offer robust protection against foreign object damage (FOD), weather extremes, and environmental threats. Whether your 747-400 is in passenger service or converted for cargo, Jet Brella’s engineered solution improves engine preservation, reduces unplanned maintenance, and keeps your fleet flight-ready. Kits are sold as complete four-engine sets (Part Number JB-747-400-ENG-KT) or customized by engine model.

Inlet Covers

Tailored for the Boeing 747-400, Jet Brella’s inlet covers are designed to shield engine fronts from contamination and environmental ingress. Molded to the specific geometry of the PW4056, CF6-80C2B1F, and RB211-524G/H engines, they defend against threats such as airborne particles, wildlife intrusion, and moisture accumulation. Available in both plug-in and cushion-fit styles, these covers install quickly and securely with no tools required—perfect for rapid turnarounds or unpredictable ramp conditions. Built with high-durability materials, they maintain a tight seal, even in blustery or shifting weather scenarios.

Exhaust Covers

Jet Brella’s exhaust covers for the 747-400 protect the engine’s aft section from debris, snow, rain, and nesting wildlife. Each cover is sculpted to match the unique exhaust profile of its corresponding engine type, whether Rolls-Royce, GE, or P&W. Designed for one-person application without tools, installation takes less than a minute and can be done in virtually any ramp environment. Made from high-performance, weather-resistant fabrics, they guard vital components from wear, rust, and long-term exposure damage, ideal for aircraft parked short or long-term.

Dual Venting Engine Covers for 747‑400

Hi‑Flow Dual Venting Inlet Cover

• Engine-Specific Fit: Every Jet Brella inlet cover is engineered for the exact contours of the PW4056, CF6-80C2B1F, or RB211-524G/H engines, providing a precision fit that minimizes airflow disruption while engines are idle.

• Venting System:

  • An automatic pressure-relief activates under backpressure to avoid internal overpressure incidents.

  • Integrated mesh vents promote airflow circulation, helping regulate internal humidity and mitigating corrosion risk during inactivity.

• Protective Capability:

  • Guards internal components from sand, rain, ice crystals, and airborne debris.

  • Prevents windmilling of fan blades, reducing wear and mechanical fatigue during idle or parked periods.

  • Works best when paired with Jet Brella’s exhaust covers for full engine enclosure.

• Installation & Security:
  

  • Innovative strap-and-buckle system allows for tool-free, fast securing by a single crew member.

  • Rugged enough to resist wind shear, ramp turbulence, and rain impact.

  • Safe to use immediately following engine shutdown, thanks to its heat-tolerant construction.

• Convenience & Storage:

  • Umbrella-style collapsible design allows for compact storage in standard onboard compartments or ground kits.

  • Optional deep-inlet strut cone extension provides added sealing depth.

  • Heat-resistant materials permit installation shortly after engine cool-down.

• Customization:

  • Choose from a range of mesh panel colors and heavy-duty Lycra fabric finishes.

  • Personalize with embroidered logos, aircraft registration, or squadron insignia.

  • Optional sand-resistant enhancements are available for aircraft operating in desert or arid environments.

Jet Engine FOD Damage Protection for 747‑300

Purpose‑Built Protection

Jet Brella’s all-weather defense system helps shield 747-300 engines from runway threats like snow, ice, sand, grit, wildlife, and salt spray, particularly crucial for aircraft stationed in coastal or high-dust environments. The covers help reduce blade erosion, guide vane wear, and spinner damage caused by environmental exposure.

Weather Shielding

• Prevents water, ice, and slush from seeping into engine internals during extreme weather.

• Reduces the chances of internal ice shards causing engine damage.

• Enhances engine performance and readiness in winter conditions by minimizing moisture accumulation.

Operational Safety

• Acts as a barrier against tool drops or debris entry during ground servicing.

• Improves overall ramp safety for personnel working in and around engine zones.

Anti‑Corrosion Benefits 

• Reduces exposure of vital engine areas to moisture and salt, key for long-term reliability in humid or seaside operations.

• Extends service intervals and boosts reliability by minimizing internal corrosion and oxidation.
