Narrative:

First officer flew instrument approach to runway 26L (grr). Coupled ILS approach was on speed and uneventful. 'Runway in sight' call was made by captain at 200 ft above runway 26L minimums. Most recent brake action report indicated fair braking. Runway markings were obscured by snow. First officer touched down on speed near runway center. Approximately 500 ft after nosewheel touchdown, with little or no reverse thrust, felt bump on runway and aircraft drifted right of centerline. Estimated actual runway braking at poor to nil. Captain called for more left rudder and then placed feet on pedals and added left rudder to control aircraft back to centerline. Rollout and taxi in was uneventful. Postflt inspection of right main landing gear indicated damage. Captain requested and was provided a visual inspection of runway 26L in a snow plow with a spotlight. No evidence of debris or damaged runway edge lights were discovered. Human performance: northern tower airports should plow more often during a snowstorm and give more accurate (current) mu readings.

Original NASA ASRS Text

Title: DC9-30 CREW HAD RWY EXCURSION ON RWY 26L AT GRR.

Narrative: FO FLEW INST APCH TO RWY 26L (GRR). COUPLED ILS APCH WAS ON SPD AND UNEVENTFUL. 'RWY IN SIGHT' CALL WAS MADE BY CAPT AT 200 FT ABOVE RWY 26L MINIMUMS. MOST RECENT BRAKE ACTION RPT INDICATED FAIR BRAKING. RWY MARKINGS WERE OBSCURED BY SNOW. FO TOUCHED DOWN ON SPD NEAR RWY CTR. APPROX 500 FT AFTER NOSEWHEEL TOUCHDOWN, WITH LITTLE OR NO REVERSE THRUST, FELT BUMP ON RWY AND ACFT DRIFTED R OF CTRLINE. ESTIMATED ACTUAL RWY BRAKING AT POOR TO NIL. CAPT CALLED FOR MORE L RUDDER AND THEN PLACED FEET ON PEDALS AND ADDED L RUDDER TO CTL ACFT BACK TO CTRLINE. ROLLOUT AND TAXI IN WAS UNEVENTFUL. POSTFLT INSPECTION OF R MAIN LNDG GEAR INDICATED DAMAGE. CAPT REQUESTED AND WAS PROVIDED A VISUAL INSPECTION OF RWY 26L IN A SNOW PLOW WITH A SPOTLIGHT. NO EVIDENCE OF DEBRIS OR DAMAGED RWY EDGE LIGHTS WERE DISCOVERED. HUMAN PERFORMANCE: NORTHERN TWR ARPTS SHOULD PLOW MORE OFTEN DURING A SNOWSTORM AND GIVE MORE ACCURATE (CURRENT) MU READINGS.
