Gulfstream G100 (SPX)

Jet Brella Gulfstream G100 Engine Covers

Jet Brella’s engineered engine cover system for the Gulfstream G100 is designed to provide complete protection for aircraft equipped with Honeywell TFE 731-40 engines. Whether parked for an overnight stop or in long-term hangar storage, these inlet and exhaust covers guard against foreign object damage (FOD), ramp debris, and harsh weather conditions. Built for performance, quick setup, and longevity, Jet Brella’s lightweight, dual-venting covers preserve engine condition, reduce maintenance cycles, and support long-term aircraft readiness. Part Number: JB-TFE731-40-KT.

Inlet Covers

Designed specifically for the Gulfstream G100, Jet Brella’s inlet covers fit the TFE 731-40 engine nacelles with precision. Each unit weighs 4.5 lbs and collapses to 26″ high by 9″ wide, making it ideal for compact transport and quick deployment. The dual-venting system prevents internal pressure buildup and reduces condensation during storage, while effectively sealing out birds, grit, moisture, and airborne contaminants. No hardware or tools are required for installation rubber feet contact the inner nacelle to hold each unit securely in place. Each rubber cone includes a spinner bearing for added seal stability and flexibility. Carry bags with breathable mesh and vertical storage loops are included with every set.

Exhaust Covers

Jet Brella’s exhaust covers for the G100 complete the full-engine protection suite. Each unit is constructed from rigid, thermoformed FAA FAR 25.853-approved material with a 22.75″ diameter and 2.5″ depth. Weighing only 3.0 lbs, these covers are designed to block moisture, grit, and environmental contaminants without the need for permanent hardware. Sliding clips allow for easy, secure attachment. Breathable mesh carry bags with vertical loops are included for organized storage and rapid deployment.
