Narrative:
Southwest Airlines flight WN4069, a Boeing 737-8H4, descended below minimum altitude during the approach to runway 13 at OKL. The OKC Tower controller received a low altitude alert and contacted WN4069. The flight then climbed and performed a go-around.

ADS-B data suggest the aircraft descended to 1725 ft calibrated altitude at about 8 nm from the runway.
According to the RNAV (GPS) RWY 13 approach procedure, the aircraft should have been descending from 4000 feet over WABUT (the IF, at 8.7 nm from the threshold) to 2600 feet over ELUCK (the FAF, at 4 nm).
