From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.
What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot in command (PIC)/instructor reported engine was not at the proper RPM during takeoff roll on a training flight with a student pilot. Pic/instructor aborted takeoff and returned to maintenance. The reduced RPM was determined to be vapor lock of the 91 non-ethanol (winter blend) fuel being used. Blending the 91 non-ethanol with 100LL avgas has seemed to resolve the issue.
