What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot was conducting full stop/taxi backs and kcfo. On second iteration pilot noticed oil pressure light was at the high side of red/low side of green and became distracted monitoring the issue. Pilot extended downwind. Pilot conducted gumps check, but wasn't sure if he would do a go around or continue for landing, and decided that if he choose to land he would extend gear on final. On final pilot forgot to extend gear. The aircraft is an older model with no audio gear horn, and the gear light was blocked by the yoke.
