Jet Brella Boeing 737‑900 Engine Covers

Jet Brella’s engine protection system for the Boeing 737‑900 is designed for the CFM56‑7B engines that power this stretched member of the 737 Next Gen family. Designed with operators of both commercial and private variants in mind, our complete engine cover kit includes inlet and exhaust covers to provide comprehensive, all‑weather defense during periods of inactivity on the ramp. Available as a full set (Part Number JB‑CFM‑56‑7‑KT) or as individual inlet (JB‑CFM‑56‑7‑2V) and exhaust (JB‑CFM‑56‑7‑XG) covers, these high‑visibility red units enhance safety and operational readiness. Engineered to prevent environmental wear and foreign object damage (FOD), they help extend engine life and reduce long‑term maintenance costs. Full specifications and custom quote options are available from Jet Brella’s support team.

Inlet Covers

Jet Brella’s inlet covers for the 737‑900 are engineered for precise nacelle coverage and long‑lasting engine protection. Custom‑fit to the CFM56‑7 engine inlets, these covers block airborne debris and moisture while remaining lightweight and easy to handle. Offered with custom personalized finishes, stitched logos, and a variety of color options, they combine form and function for operators in both fleet and private use.

Exhaust Covers

Our exhaust covers for the 737‑900 are designed to shield the rear engine sections from threats such as windborne debris, nesting wildlife, sand, snow, ice, and temperature‑related damage. Available in both pillow and plug configurations, they install and remove in seconds, no tools required. Tailored specifically for the 737‑900’s exhaust dimensions, these covers form a snug seal that holds fast in high winds and harsh environments, delivering dependable protection on the ramp or in long‑term storage.

Dual Venting Engine Covers for 737‑900

Hi‑Flow Dual Venting Inlet Cover

• Tailored Fit: Precisely contoured for the CFM56‑7B engines of the 737‑900, the inlet cover’s advanced shaping ensures an airtight seal and aerodynamic compatibility.

• Venting System:

  • A built‑in bypass vent opens automatically under back‑pressure, preventing air entrapment and minimizing condensation.

  • Passive mesh vents encourage natural airflow to reduce internal humidity and corrosion risk.

• Protective Capability:

  • Deflects small particulates and sand that can damage internal engine components.

  • Prevents fan rotation/windmilling caused by high winds, preserving blade integrity while parked on the ramp. Requires both inlet and exhaust covers (full kit).

• Installation & Security:

  • Quick‑attach strap system tailored to 737‑900 nacelle dimensions.

  • Tool‑free, single‑person install with quick‑release features for rapid access.

  • Robust securing points withstand harsh ramp conditions and turbulent airflow.
