Aircraft
Climbing out; shortly after flap retraction we received an amber CAS alert - UNCMDED STAB. Climb was continued to a safe altitude to allow checklist reference and procedure. At 7;800 feet there was a temporary CAS message of a PYLON HOT L message. At that point we declared an emergency and returned via radar vectors and landed without incident. During the final phase of our visual approach the CAS message cleared. The aircraft is currently being evaluated by Gulfstream technicians.
No additional information was provided by the secondary narrative.
A Gulfstream V flight crew returned to their departure airport following receipt of UNCOMED STAB and PYLON HOT L CAS warnings.
