NEARING COMPLETION OF HIS FLIGHT ACROSS THE U.S., AND ABOUT 33 MI FROM HIS DESTINATION, THE PILOT DESCENDED AND ENCOUNTERED AN OVERCAST LAYER. UNABLE TO SEE THE UNDERLYING RISING MOUNTAINOUS TERRAIN, AND UNCERTAIN OF HIS EXACT POSITION, THE PILOT REQUESTED ATC ASSISTANCE. HE ADVISED THE CONTROLLER THAT HE HAD A 'HOLE' AND WAS GOING THROUGH IT. THE AIRPLANE WAS RADAR IDENTIFIED. THE CONTROLLER APPROVED THE DESCENT AND ADVISED THE PILOT TO MAINTAIN VFR AT ALL TIMES. IN RESPONSE TO THE PILOT'S INQUIRY 'HOW LOW IS THE TERRAIN UNDER ME RIGHT NOW?', THE CONTROLLER STATED 'THE TERRAIN IS NO FACTOR FOR YOU SIR.' SHORTLY THEREAFTER THE PILOT STATED HE WAS '...LOSING VFR.' THE AIRPLANE IMPACTED MOUNTAINOUS TERRAIN AT 5,550 FT MSL.
Probable Cause: THE PILOT'S INADVERTENT FLIGHT INTO IMC, THE RADAR CONTROLLER'S ISSUANCE OF INCORRECT TERRAIN INFORMATION, THE CONTROLLER'S FAILURE TO ISSUE A LOW ALTITUDE SAFETY ALERT, AND THE CONTROLLER'S FAILURE TO PROVIDE EMERGENCY SERVICES.
