IAD01LA029 · Piper PA 46-350P

When the private pilot, co-pilot and passenger arrived at the airport it began to snow heavily. The airplane was pre-flighted, then towed out of the heated hangar and fueled. The private pilot taxied to the end of the 5,400 foot long runway, parked, and performed an engine run-up. After the run-up, the co-pilot reached the Elkins, West Virginia, AFSS on his cell phone, received a weather briefing, filed an IFR flight plan, and requested an IFR clearance. Since Elkins was not the primary AFSS for the area, the briefer placed him on hold to service his request. The call got disconnected, so he called the FSS back. Due to the long hold time, the co-pilot then called Indianapolis Center and received an IFR clearance. Once the clearance was obtained, the private pilot performed another engine run-up and noticed that about 3 to 4 inches of slush had accumulated on the runway, and about 1/2 to 3/4 inches of slush had accumulated along the surface of both wings. The pilots discussed if they should return to the hangar and wipe off the wings, but agreed that the slush would "blow-off" during the take-off roll. The private pilot estimated that he used about 4,500 feet of the runway before he obtained 80 knots (Vr). He rotated the airplane, but it did not lift normally. To avoid obstructions, the private pilot simultaneously turned the aircraft to the right, and retarded the throttle. The airplane touched down, slid, turned, and came to rest upright facing the runway. Examination of the airplane revealed that both wings were covered with snow, and localized areas of ice were found along the top surfaces of both wings near the trailing edge. The air intake and pitot tube were absent of debris. According to the airplane's pre-flight checklist, the wings and empennage surfaces should be clear of ice, snow, and frost prior to take-off. The pilot estimated that from the time the airplane was pulled from the hangar to the time of the accident was about 1-hour. The pilot also reported that there were no mechanical deficiencies.
