Probable Cause #63: Stick To The Procedure
This article originally appeared in IFR Refresher, Oct. 2007.On Oct. 7, 2005, the pilot of an A36 Bonanza deviated significantly from the ILS Runway 27 approach procedure he was flying into the Pike County Airport (PBX) at Pikeville, Ky. The pilot lost control of the aircraft and crashed just south of Pikeville, killing all three people on board. The flight began many hours earlier when the pilot contacted the Louisville, Ky., Automated Flight Service Station (AFSS) just after noon (EDT), explaining his intention to fly to Pikeville from Paducah (PAH). Paducah is located in Western Kentucky along the Illinois River. Pikeville is 286 nautical miles to the east not far from the Virginia and West Virginia state lines. The Bonanza pilot asked the AFSS specialist about "weather echoes" in the eastern portion of Kentucky. The specialist explained the returns as light rain over the central portion of the route and at the destination, part of a slow-moving cold front over Eastern Kentucky. The area forecast called for a broken ceiling at 700 feet, an overcast layer at 1,500 feet, four miles visibility in light rain and mist and a north wind at five knots. Two previous automated weather reports from Pikeville showed a broken ceiling at 300 feet with three miles visibility and later 300-foot scattered with 10 miles visibility and calm winds.
