Narrative:

The aircraft was landed at ril airport from the localizer/DME-a approach. This approach requires a steep descent gradient to lose altitude from the MDA 1656 ft AGL to the airport in 1 3/4 mi. There was no control tower at this field and subsequently a braking and field condition report was not included in the WX observer's report. This would have affected our decision to land at ril. The aircraft landed and experienced no or little deceleration. The aircraft was hydroplaning on approximately 1/2 inch to 1 inch slush and snow (this was found out after the incident and looking at the runway). The aircraft began to slide down the runway at approximately 2000 ft from the end of the runway. Engines #1 and #4 were shut down to help in the deceleration. The aircraft continued to slide off the end of the runway and stopping approximately 150-200 ft off the end in the grass. There were no injuries and no aircraft damage.

Original NASA ASRS Text

Title: ON LNDG ACFT SLID OFF END OF RWY. NO INJURIES, NO DAMAGE TO ACFT.

Narrative: THE ACFT WAS LANDED AT RIL ARPT FROM THE LOC/DME-A APCH. THIS APCH REQUIRES A STEEP DSCNT GRADIENT TO LOSE ALT FROM THE MDA 1656 FT AGL TO THE ARPT IN 1 3/4 MI. THERE WAS NO CTL TWR AT THIS FIELD AND SUBSEQUENTLY A BRAKING AND FIELD CONDITION RPT WAS NOT INCLUDED IN THE WX OBSERVER'S RPT. THIS WOULD HAVE AFFECTED OUR DECISION TO LAND AT RIL. THE ACFT LANDED AND EXPERIENCED NO OR LITTLE DECELERATION. THE ACFT WAS HYDROPLANING ON APPROX 1/2 INCH TO 1 INCH SLUSH AND SNOW (THIS WAS FOUND OUT AFTER THE INCIDENT AND LOOKING AT THE RWY). THE ACFT BEGAN TO SLIDE DOWN THE RWY AT APPROX 2000 FT FROM THE END OF THE RWY. ENGS #1 AND #4 WERE SHUT DOWN TO HELP IN THE DECELERATION. THE ACFT CONTINUED TO SLIDE OFF THE END OF THE RWY AND STOPPING APPROX 150-200 FT OFF THE END IN THE GRASS. THERE WERE NO INJURIES AND NO ACFT DAMAGE.
