What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: on January 03, 1997, at 0910L, a westwind 1124, piloted by kenneth hepner and phyllis upchurch sustained minor damage after the aircraft slid off the end of runway 36 at the Jackson Hole Airport. Shortly after 0900L the aircraft was cleared for approach. The glidescope was notamed out of service. Braking action was reported to be poor by a lear jet approximately 10 minutes prior to this incident. This braking action report was forwarded to and acknowledged by N24RH. Upon landing, initial braking was good. Thrust reversers were deployed, and the aircraft started to veer to the left. Mr. Hepner believed that braking control was lost. He retracted the thrust reversers and corrected the ships direction to the runway center line. This scenario was repeated 3 to 4 more times. The aircraft was approximately 1000 feet from the end of the runway when the front gear began to hydroplane. The aircraft then slid sideways off the end of the runway at 30-40 knots, struck the runway end identification light, and stopped in 2 feet of snow, 60 feet past the end of the runway. Damage to the aircraft included a tear in the skin on the right side of the fuselage, forward of the wing. No injuries were noted. This is a final report.
