Supplemental type certificate (STC) ST01075DE, for Gulfstream G150 flap and slat actuator heaters

Available today from Peregrine is the supplemental type certificate (STC) ST01075DE, to improve high-lift system performance in cold weather landing situations.

The STC covers the installation of heaters to prevent inadvertent freezing of the aircraft’s linear actuators that control wing flaps and slats positions. The heaters ensure the reliable operation and deployment of the leading-edge slats and flaps in all operational environments.

Operators of the G150 can contact their Gulfstream Authorized Service Center for installation of this STC.


Peregrine provided all engineering, test and certification data needed to obtain the Supplemental Type Certificate approval.
