1. PORTABLE VOR HAS BEEN INSTALLED BUT THE MAINTENANCE CREW HAS
ENCOUNTERED CONSIDERABLE DIFFICULTY IN GETTING IT TO PASS FLIGHT
CHECK DUE TO EXCESSIVE COURSE ERROR. THE PRIMARY DIFFICULTY HAS
BEEN CAUSED BY A LACK OF SPARE PARTS AND POOR CONDITION OF
EQUIPMENT UPON ARRIVAL EVEN THOUGH IT WAS DIRECTLY OUT OF OVER
HAUL. PARTS ARE VERY HARD TO LOCATE BECAUSE AIR FORCE HAS
TURNED IN MOST OF THIS TYPE OF EQUIPMENT IN THIS PART OF THE
WORLD.
2. THE VOR CAN BE USED AT THIS TIME BUT WAS FOUND TO HAVE A
COURSE ERROR OF APPROX 6.4 DEGREES DURING FLIGHT CHECK WITH MAX
ALLOWABLE BEING 5 DEGREES.
3. SOME PARTS ARE EXPECTED FROM ON 8 OCT WHICH MAY
PARTIALLY ALLEVIATE THE SITUATION. ANOTHER FLIGHT CHECK WILL
BE REQUESTED AS SSON AS IMPROVED EQUIPMENT OPERATION INDICATES
READINESS. MAINTENANCE CREWS ANTICIPATE A CONTINUING PROBLEM
OF KEEPING THIS EQUIPMENT IN SHAPE DUE TO A SHORTAGE OF SPARE
REPRODUCTION BY OTHER THAN THE ISSUING OFFICE IS PROHIBITED? Copy t4a
