C150 STUDENT PLT GOT LOST ON SOLO XCOUNTRY.

Narrative

ON NOV/XA/99; A STUDENT PLT CAME TO ME FOR A SOLO XCOUNTRY ENDORSEMENT. THE FLT WAS TO BE CONDUCTED FROM EYQ-SGR-GLS AND RETURN. I REVIEWED HIS FLT PLANNING AND GAVE HIM THE ENDORSEMENT. ON THE RETURN FLT; THE STUDENT PLT GOT LOST. AFTER REALIZING THAT HE NEEDED HELP; MONTGOMERY COUNTY FSS WAS CONTACTED. RECEIVED ASSISTANCE AND LANDED SAFELY. AFTER THE FLT; IT WAS DISCOVERED ON THE RETURN FLT (GLS-SGR LEG) THE STUDENT HAD THE WRONG HDG ENTERED INTO HIS FLT LOG. THE STUDENT PLT WAS NOT MY STUDENT AND HAD FLOWN THIS RTE PRIOR; WHILE RECEIVING INSTRUCTION. DUE TO BEING A JUNIOR FLT INSTRUCTOR; I ALLOWED MYSELF TO MISPERCEIVE HIS ABILITIES; WHICH RESULTED IN NOT NOTICING THE ERROR IN PLANNING. I NOW REALIZE HOW CRITICAL IT IS TO TREAT EACH XCOUNTRY AS IT IS THE STUDENT'S FIRST; WHETHER SOLO OR DUAL. TO PREVENT FUTURE RECURRENCE; I HAVE SET A PERSONAL STANDARD OF NOT ENDORSING OTHER STUDENTS UNTIL I AM MUCH MORE EXPERIENCED. ALSO; I'M OBTAINING REMEDIAL TRAINING ON ENDORSEMENTS AND INSTRUCTOR'S RESPONSIBILITIES.
