Narrative:

Summary of the reporter's narrative indicates that this was an IFR cross country training flight in which the approach chart of the approach requested and in use did not show 2 of the major intxns, samie and mopio, given by ATC in the approach clearance instructions to the medford, or, airport. However, these intxns were shown on the ILS DME approach chart which was subsequently used by the flight crew, but then misinterpreted by the pilots to show the DME fix distance from the VORTAC rather than the localizer of the airport. Therefore, the student became disoriented and confused. The flight instructor also was confused, helped by not only the misinterp of the approach chart but also the aircraft navigation equipment known problems, wherein they were usually not repaired after being reported by the pilots. Subsequently, the flight became VFR and landed without further incident. However, the reporter complained about the VOR DME runway 14 approach chart not noting these intxns and the lack of aircraft avionics repair by the FBO operator.

Title: DURING AN IFR XCOUNTRY TRAINING FLT THE STUDENT BECAME DISORIENTED AND DEVIATED FROM THE ASSIGNED HOLDING PATTERN FIX.

Narrative: SUMMARY OF THE RPTR'S NARRATIVE INDICATES THAT THIS WAS AN IFR XCOUNTRY TRAINING FLT IN WHICH THE APCH CHART OF THE APCH REQUESTED AND IN USE DID NOT SHOW 2 OF THE MAJOR INTXNS, SAMIE AND MOPIO, GIVEN BY ATC IN THE APCH CLRNC INSTRUCTIONS TO THE MEDFORD, OR, ARPT. HOWEVER, THESE INTXNS WERE SHOWN ON THE ILS DME APCH CHART WHICH WAS SUBSEQUENTLY USED BY THE FLC, BUT THEN MISINTERPRETED BY THE PLTS TO SHOW THE DME FIX DISTANCE FROM THE VORTAC RATHER THAN THE LOC OF THE ARPT. THEREFORE, THE STUDENT BECAME DISORIENTED AND CONFUSED. THE FLT INSTRUCTOR ALSO WAS CONFUSED, HELPED BY NOT ONLY THE MISINTERP OF THE APCH CHART BUT ALSO THE ACFT NAV EQUIP KNOWN PROBLEMS, WHEREIN THEY WERE USUALLY NOT REPAIRED AFTER BEING RPTED BY THE PLTS. SUBSEQUENTLY, THE FLT BECAME VFR AND LANDED WITHOUT FURTHER INCIDENT. HOWEVER, THE RPTR COMPLAINED ABOUT THE VOR DME RWY 14 APCH CHART NOT NOTING THESE INTXNS AND THE LACK OF ACFT AVIONICS REPAIR BY THE FBO OPERATOR.
