Max Trescott examines the tragic crash of a Citation S550, N666DS, in San Diego during an attempted RNAV (GPS) 28R approach to Montgomery Field at approximately 3:46 AM. After departing Teterboro, NJ, and making a fuel stop at Wichita's Jabara Field, the pilot continued westbound overnight. After refueling, the flight continued to San Diego, where the Montgomery Field AWOS was inoperative, and weather was marginal. The pilot requested weather at nearby airports. The aircraft correctly crossed the final approach fix PENYY at 2500 feet but then flew below the glide path and failed to stabilize. Speeds decreased from 200 knots to 124 knots on final, increasing workload and destabilizing the descent. Flight path data suggests the pilot may have flown the approach as if it were a non-precision LNAV approach, mistakenly observing step-downs like the PALOS fix, which applies only to LNAV. Two level-offs occurred—one around 1300–1400 feet, then again at 500 feet—further evidence of a step-down approach profile
