## Analysis

STUDENT PILOT BOUGHT ACFT PREVIOUS DAY, ASKED INSTRUCTOR TO FLY ACFT WITH HIM TO HOME AIRPORT. CFI DELAYED EN ROUTE TO PRACTICE TOUCH AND GO. ON GO AROUND ENGINE WOULD NOT PRODUCE FULL POWER AND ACFT WOULD NOT CLIMB. DURING SUBSEQUENT INTERVIEW PIC/CFI TOLD FAA INSPECTOR HE NOTED THAT FULL FLAPS WERE STILL EXTENDED AFTER THE ACFT LIFTED OFF. WHEN HE RAISED THE FLAPS ACFT SETTLED TO RUNWAY. ACFT WAS GROUND-LOOPED TO AVOID RUNNING OFF RUNWAY END.

## Other investigations on N1613P (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
