Date: 11/7/1968
Response: CONCURRENTLY, A TELEGRAPHIC OPERATIONS AND MAINTENANCE ALERT WAS SENT TO ALL REGIONS, AREA OFFICES, AND FLIGHT STANDARDS OFFICES ON OCTOBER 29, 1968, REQUESTING THAT ALL KNOWN USERS OF THIS RECEIVER BE ADVISED THAT ERRATIC OPERATION AND FALSE REVERSALS HAVE BEEN REPORTED. RESTRICTIONS ON THE USE OF THE 806A RECEIVER FOR EN ROUTE OPERATIONS AND VOR INSTRUMENT APPROACHES WERE ALSO REQUESTED. IN ADDITION, THE MANUFACTURER WAS REQUESTED BY TELEGRAM TO ALSO ALERT ALL KNOWN USERS OF THE EQUIPMENT AS SOON AS POSSIBLE. A COPY OF OUR ALERT NOTICE TO THE FIELD OFFICES IS ENCLOSED. WE BELIEVE THAT THE ABOVE PRECAUTIONARY ACTION SUBSTANTIALLY PARALLELS YOUR RECOMMENDATIONS.
