NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE CERTIFICATED GLIDER PILOT, THE SOLE OCCUPANT, DEPARTED FOR A LOCAL AREA FLIGHT WITH LIFT CONDITIONS DESCRIBED AS WEAK TO MODERATE. THE WRECKAGE WAS LOCATED ABOUT 2 HOURS AFTER DEPARTURE IN AN AREA OF RUGGED MOUNTAINOUS TERRAIN. THE LEFT WING OF THE GLIDER STRUCK A ROCKY RIDGE AND CAME TO REST ABOUT 300 FEET BELOW THE RIDGE LINE. OTHER GLIDER PILOTS REPORTED THAT THE ACCIDENT PILOT HAD A PROCLIVITY TO FLY OVER MOUNTAINOUS AREAS AT LOW ALTITUDES. A TOXICOLOGICAL EXAMINATION DISCLOSED THE PRESENCE OF A CARDIAC ANTIARRHYTHMIC DRUG. THE QUANTITY OF DRUG FOUND IS CONSIDERED TO BE AT THERAPEUTIC LEVELS. ACCORDING TO A CAMI PHYSICIAN, THE DRUG, IN VIEW OF THE PILOT'S PREVIOUS MEDICAL HISTORY, DID NOT BY ITSELF, PRESENT A DISQUALIFYING CONDITION THAT WOULD HAVE BEEN EXPECTED TO ADVERSELY AFFECT THE PILOT'S ABILITY TO PILOT A GLIDER.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE PILOT'S POOR INFLIGHT DECISION TO FLY OVER MOUNTAINOUS TERRAIN AT AN INADEQUATE ALTITUDE.
