## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) AMENDMENT TO FOLLOW. (-23 AMENDMENT) ON AUGUST 17, 2004, N199GL, A BEECHCRAFT BE-99, CRASHED ON TOP OF MT. BALDY (APPROXIMATELY 9100 FEET MSL) NEAR NEIHART, MONTANA, AND ALONG THE CONTINENTAL DIVIDE, AT APPROXIMATELY 2340 LOCAL TIME. THE AIRCRAFT WAS OPERATED BY ALPINE AVIATION, INC., A PART 135 AIR TAXI OPERATOR OPERATING UNDER A U.S. POSTAL SERVICE CONTRACT. LARRY BAIER, THE PILOT-IN-COMMAND (PIC), WAS FATALLY INJURED, ALONG WITH HIS PILOT-RATED PASSENGER, ^PRIVACY DATA^ THE AIRCRAFT WAS OPERATED ON A COMPANY VISUAL FLIGHT RULES (VFR) FLIGHT PLAN WHICH INDICATED THAT IT WOULD OPERATE AT 12,500 FEET MSL. RESIDENTS OF NEIHART, MONTANA, WHICH IS LOCATED 6 MILES SOUTHWEST OF THE ACCIDENT, INDICATED THAT THUNDERSTORMS EXISTED AROUND THE TIME OF THE ACCIDENT. THE NATIONAL WEATHER SERVICE AREA FORECAST INDICATED A CHANCE OF THUNDERSTORMS AND RAIN SHOWERS ALONG THE CONTINENTAL DIVIDE. CONVECTIVE SIGMET'S 27W AND 30W WERE VALID FOR SEVERE WEATHER NEAR THE ACCIDENT SITE. THE AIRCRAFT WAS REQUIRED TO BE OPERATED UNDER VFR CONDITIONS FOR TWO REASONS: 1. THE PILOT IN COMMAND DID NOT HAVE A CURRENT INSTRUMENT PROFICIENCY CHECK (FAR 135.297)                                                GIVEN BY THE COMPANY WITHIN THE LAST 6 MONTHS. 2. THE PILOT IN COMMAND WAS OPERATING WITH A PASSENGER WHICH LIMITED THE OPERATIONS TO VFR GIVE THE AIRCRAFT DID NOT HAVE AN AUTOPILOT INSTALLED. THE INVESTIGATING OFFICE HAS LEARNED THAT THE PILOT IN COMMAND HAD A HISTORY OF HAULING HIS PILOT RATED FRIENDS AS PASSENGERS. WE HAVE TWO REPORTS THAT THE PIC WOULD LET THESE PASSENGERS OPERATED THE AIRCRAFT BOTH UNDER VFR AND IFR CONDITIONS. ONE REPORT INDICATES THE PIC LOGGED THIS TIME IN THE PASSENGERS' LOGBOOK AS DUAL. THIS IS CONTRARY TO THE FEDERAL AVIATION REGULATIONS.
