Aircraft Accident/Incident Report
Morgan, Utah 84050

NTSB Narrative Summary Released at Completion of Accident
According to the pilot, he was performing a standard approach to the runway. The pilot stated that the approach was flown with an approach speed of "105 to 110 knots." In a telephone interview, he stated that 35 degrees of flaps were used. The airplane touched down "500 to 700 feet from [the] approach end" of the runway and braking began almost immediately. Braking action was ineffective and it was increased with no result. The airplane drifted to the right, leaving the runway environment and impacting a hangar and fuel truck, causing substantial damage. According to the owner's manual for the airplane, approach speed should be 102 mph (88 knots). The pilot said that the braking action was poor due to "seal coating" of the runway. An FAA inspector described the runway surface as having the consistency of "putty." A "coal-tar sealer/rejuvinator" was applied to the runway by Brewercote in October of 2003. According to the specifications provided by the Utah Division of Aeronautics, the coal-tar sealant "is to seal the pavement from oxidation, and to rejuvenate the asphalt binder in place." It is composed of a minimum of 35 percent coal-tar pitch conforming to ASTM D-490, RT-12, Standard Specification for road Tar.On June 18, 2004, a skid test was conducted on runway 03/21. The test revealed skid values ranging from 2.4 to 10.9 and an average value of 6.3. The calculated MU-meter frictional value which ranged from .035 to .160 with the average MU-meter frictional value of .093. According to the Operations Friction Correlation Chart, this friction rating is poor.
NTSB Probable Cause Narrative
the poor friction value on the runway rendering braking action inadequate. Contributing factors include the excessive approach speed, and the pilot's inability to maintain directional control of the aircraft.
