Narrative:

The en route portion of the flight was routine with minor deviations around precipitation areas. Lex approach control changed our approach type 3 times from a visual runway 22, to an ILS runway 22, and ultimately, to an ASR approach to runway 22. Approach control vectored us to and cleared us for an ASR runway 22 approach. The approach was routine as we backed it up with the ILS. The airport and entire runway came into view approximately 1500 ft MSL (500 ft AGL) with the aircraft stabilized and on speed. The landing was in the touchdown zone. Reverse thrust was selected. Almost immediately, the aircraft began to slide sideways to the left. All attempts to correct the slide were ineffective. The aircraft exited the left side of the runway. The aircraft was secured and transportation for the passenger to the terminal was arranged.

Original NASA ASRS Text

Title: RWY EXCURSION BY LTT.

Narrative: THE ENRTE PORTION OF THE FLT WAS ROUTINE WITH MINOR DEVS AROUND PRECIPITATION AREAS. LEX APCH CTL CHANGED OUR APCH TYPE 3 TIMES FROM A VISUAL RWY 22, TO AN ILS RWY 22, AND ULTIMATELY, TO AN ASR APCH TO RWY 22. APCH CTL VECTORED US TO AND CLRED US FOR AN ASR RWY 22 APCH. THE APCH WAS ROUTINE AS WE BACKED IT UP WITH THE ILS. THE ARPT AND ENTIRE RWY CAME INTO VIEW APPROX 1500 FT MSL (500 FT AGL) WITH THE ACFT STABILIZED AND ON SPD. THE LNDG WAS IN THE TOUCHDOWN ZONE. REVERSE THRUST WAS SELECTED. ALMOST IMMEDIATELY, THE ACFT BEGAN TO SLIDE SIDEWAYS TO THE L. ALL ATTEMPTS TO CORRECT THE SLIDE WERE INEFFECTIVE. THE ACFT EXITED THE L SIDE OF THE RWY. THE ACFT WAS SECURED AND TRANSPORTATION FOR THE PAX TO THE TERMINAL WAS ARRANGED.
