During a power failure, while working local control, I found out that the bak 14 arresting gear automatically raises. I had an aircraft on short final and just happened to look at the cable with binoculars and observed it up. Aircraft was advised and landed beyond cable. After investigating, found that FAA personnel did not know this occurs. We have already had 1 incident with the cable system -- an aircraft claims the cable was partially raised, which caused his nose gear to collapse. Suggest: air national guard personnel (ANG) remain at bak 14 site and raise, lower and secure cable as needed. This is another accident waiting to happen! Callback conversation with reporter revealed the following information: reporter claims that power failure occurred on the field and not in the tower. Stated that if the cable is 'locked down', the cable will slowly raise in a 30 min period. However, if they are in the unlocked position, they go up immediately. Cables were installed approximately 18 months ago. Control box is located in tower. They are located at both ends of runway 27 and raise to a height of 4-6 inches. An aircraft accident involving the cables being up has resulted in a law suit being filed. Reporter would like to see the control box moved from the tower due to the responsibility to the controller.

Title: CTLR RPTR CLAIMS THAT WHENEVER THERE IS A PWR FAILURE, THAT THE RWY ARRESTING GEAR AUTOMATICALLY RAISES. ACFT ON FINAL APCH WAS ADVISED AND LANDED LONG.
Narrative: DURING A PWR FAILURE, WHILE WORKING LCL CTL, I FOUND OUT THAT THE BAK 14 ARRESTING GEAR AUTOMATICALLY RAISES. I HAD AN ACFT ON SHORT FINAL AND JUST HAPPENED TO LOOK AT THE CABLE WITH BINOCULARS AND OBSERVED IT UP. ACFT WAS ADVISED AND LANDED BEYOND CABLE. AFTER INVESTIGATING, FOUND THAT FAA PERSONNEL DID NOT KNOW THIS OCCURS. WE HAVE ALREADY HAD 1 INCIDENT WITH THE CABLE SYS -- AN ACFT CLAIMS THE CABLE WAS PARTIALLY RAISED, WHICH CAUSED HIS NOSE GEAR TO COLLAPSE. SUGGEST: AIR NATL GUARD PERSONNEL (ANG) REMAIN AT BAK 14 SITE AND RAISE, LOWER AND SECURE CABLE AS NEEDED. THIS IS ANOTHER ACCIDENT WAITING TO HAPPEN! CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR CLAIMS THAT PWR FAILURE OCCURRED ON THE FIELD AND NOT IN THE TWR. STATED THAT IF THE CABLE IS 'LOCKED DOWN', THE CABLE WILL SLOWLY RAISE IN A 30 MIN PERIOD. HOWEVER, IF THEY ARE IN THE UNLOCKED POS, THEY GO UP IMMEDIATELY. CABLES WERE INSTALLED APPROX 18 MONTHS AGO. CTL BOX IS LOCATED IN TWR. THEY ARE LOCATED AT BOTH ENDS OF RWY 27 AND RAISE TO A HEIGHT OF 4-6 INCHES. AN ACFT ACCIDENT INVOLVING THE CABLES BEING UP HAS RESULTED IN A LAW SUIT BEING FILED. RPTR WOULD LIKE TO SEE THE CTL BOX MOVED FROM THE TWR DUE TO THE RESPONSIBILITY TO THE CTLR.
