Narrative:

Both airways facilities technicians assigned to lawton ATCT were on leave. The tower suffered an extended power outage (more than 12 hours). The back-up technician who was brought in to restore equipment to service was not well-trained on much of the equipment. He was unable to restore the ATIS, made no attempt to restore the VASI and had difficulties with the fdio. Procedures for calling in back-up technicians should provide for someone who is familiar with the particular equipment that is OTS. Additionally, it is poor practice to have both technicians unavailable due to scheduled leave. Callback conversation with reporter revealed the following information: reporter stated that the technician who went on leave was having elective surgery, and it could have been performed after the other technician returned from his annual leave that had been scheduled well in advance. The back-up technician that came to restore the equipment was not qualified to restore some of the outages.

Title: ATC RPTR STATES THAT THE FACILITY EXPERIENCED AN EXTENDED PWR OUTAGE THAT CAUSED NUMEROUS EQUIP PROBS. ARPT FACILITY SUPPORT TO RESTORE THE EQUIP WAS LESS THAN SATISFACTORY, BECAUSE A BACK-UP TECHNICIAN WAS CALLED IN TO REPLACE THE REGULAR TECHNICIANS WHO WERE NOT AVAILABLE DUE TO ANNUAL AND SICK LEAVE.

Narrative: BOTH AIRWAYS FACILITIES TECHNICIANS ASSIGNED TO LAWTON ATCT WERE ON LEAVE. THE TWR SUFFERED AN EXTENDED PWR OUTAGE (MORE THAN 12 HRS). THE BACK-UP TECHNICIAN WHO WAS BROUGHT IN TO RESTORE EQUIP TO SVC WAS NOT WELL-TRAINED ON MUCH OF THE EQUIP. HE WAS UNABLE TO RESTORE THE ATIS, MADE NO ATTEMPT TO RESTORE THE VASI AND HAD DIFFICULTIES WITH THE FDIO. PROCS FOR CALLING IN BACK-UP TECHNICIANS SHOULD PROVIDE FOR SOMEONE WHO IS FAMILIAR WITH THE PARTICULAR EQUIP THAT IS OTS. ADDITIONALLY, IT IS POOR PRACTICE TO HAVE BOTH TECHNICIANS UNAVAILABLE DUE TO SCHEDULED LEAVE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE TECHNICIAN WHO WENT ON LEAVE WAS HAVING ELECTIVE SURGERY, AND IT COULD HAVE BEEN PERFORMED AFTER THE OTHER TECHNICIAN RETURNED FROM HIS ANNUAL LEAVE THAT HAD BEEN SCHEDULED WELL IN ADVANCE. THE BACK-UP TECHNICIAN THAT CAME TO RESTORE THE EQUIP WAS NOT QUALIFIED TO RESTORE SOME OF THE OUTAGES.
