Narrative:

On a day IFR training flight from goodyear, az, to blythe, ca, with intermediate multiple approachs at yuma, az. This type flight is routine for our type operation, so the instructor pilot has been this route before with many approachs into yuma. On the first ILS approach to runway 21R, we landed in the normal touchdown zone. On the landing roll for this touch and go, the aircraft, an small transport, ran over the arresting cable. This particular cable is permanently installed and cannot be removed (as was told by yuma tower). At this point, please note that the submitter is also a flight crew member on military heavy jet transport aircraft in air force reserves, so it is normal to land and run over the arresting cable. It was also not written company policy to land beyond arresting cable. Runway 21R is located 1700 ft from approach end. First landing was normal, the touch and go was continued on ground and after lift-off all indications were normal and the landing gear was raised. Nothing was abnormal as we ran over the cable, in aircraft control, deceleration, or feeling in rudder pedals. But, the sound of running over the cable was not the same sound as in missions past. A second ILS approach was made. Landing gear operation was normal. Again, a landing was made and the cable was run over again. Again, everything was normal except for the sound of running over the cable. The touch and go was followed through, the gear raised, and flight continued. No abnormal indications were felt or noted. At this point, I did not like the sound that was being made as we ran over the cable. So, I instructed my students to make all further lndgs beyond the cable. Note: after the first 2 approachs, I had no reason to believe the aircraft had been damaged, and I had no idea that it had been. 6 more approachs were made, all with touch and goes and flew back to goodyear for a full stop. On the maintenance post-flight, it was discovered that the nose landing gear downlock brace was bent and the nose landing gear taxi light bracket was cracked and broken. It is believed that landing and running over the arresting cable is what bent the nose landing gear downlock brace. Also note that after talking to yuma tower, they acknowledged that many GA aircraft land there and they are damaged by running over this cable. It is now our company procedure to not land at any airport that has a cable unless we touchdown beyond the cable.

Title: SMT WITH TRAINING IN PROGRESS MAKES MULTIPLE TOUCH AND GOES AT YUM ON RWY 21, RUNNING OVER ARRESTING CABLE AND ENDS UP WITH ACFT DAMAGED. PUB DEFICIENCY REF RWYS 03-21 HAVING ARRESTING CABLES INSTALLED, CREATING GA ACFT DAMAGE.

Narrative: ON A DAY IFR TRAINING FLT FROM GOODYEAR, AZ, TO BLYTHE, CA, WITH INTERMEDIATE MULTIPLE APCHS AT YUMA, AZ. THIS TYPE FLT IS ROUTINE FOR OUR TYPE OP, SO THE INSTRUCTOR PLT HAS BEEN THIS RTE BEFORE WITH MANY APCHS INTO YUMA. ON THE FIRST ILS APCH TO RWY 21R, WE LANDED IN THE NORMAL TOUCHDOWN ZONE. ON THE LNDG ROLL FOR THIS TOUCH AND GO, THE ACFT, AN SMT, RAN OVER THE ARRESTING CABLE. THIS PARTICULAR CABLE IS PERMANENTLY INSTALLED AND CANNOT BE REMOVED (AS WAS TOLD BY YUMA TWR). AT THIS POINT, PLEASE NOTE THAT THE SUBMITTER IS ALSO A FLC MEMBER ON MIL HVY JET TRANSPORT ACFT IN AIR FORCE RESERVES, SO IT IS NORMAL TO LAND AND RUN OVER THE ARRESTING CABLE. IT WAS ALSO NOT WRITTEN COMPANY POLICY TO LAND BEYOND ARRESTING CABLE. RWY 21R IS LOCATED 1700 FT FROM APCH END. FIRST LNDG WAS NORMAL, THE TOUCH AND GO WAS CONTINUED ON GND AND AFTER LIFT-OFF ALL INDICATIONS WERE NORMAL AND THE LNDG GEAR WAS RAISED. NOTHING WAS ABNORMAL AS WE RAN OVER THE CABLE, IN ACFT CTL, DECELERATION, OR FEELING IN RUDDER PEDALS. BUT, THE SOUND OF RUNNING OVER THE CABLE WAS NOT THE SAME SOUND AS IN MISSIONS PAST. A SECOND ILS APCH WAS MADE. LNDG GEAR OP WAS NORMAL. AGAIN, A LNDG WAS MADE AND THE CABLE WAS RUN OVER AGAIN. AGAIN, EVERYTHING WAS NORMAL EXCEPT FOR THE SOUND OF RUNNING OVER THE CABLE. THE TOUCH AND GO WAS FOLLOWED THROUGH, THE GEAR RAISED, AND FLT CONTINUED. NO ABNORMAL INDICATIONS WERE FELT OR NOTED. AT THIS POINT, I DID NOT LIKE THE SOUND THAT WAS BEING MADE AS WE RAN OVER THE CABLE. SO, I INSTRUCTED MY STUDENTS TO MAKE ALL FURTHER LNDGS BEYOND THE CABLE. NOTE: AFTER THE FIRST 2 APCHS, I HAD NO REASON TO BELIEVE THE ACFT HAD BEEN DAMAGED, AND I HAD NO IDEA THAT IT HAD BEEN. 6 MORE APCHS WERE MADE, ALL WITH TOUCH AND GOES AND FLEW BACK TO GOODYEAR FOR A FULL STOP. ON THE MAINT POST-FLT, IT WAS DISCOVERED THAT THE NOSE LNDG GEAR DOWNLOCK BRACE WAS BENT AND THE NOSE LNDG GEAR TAXI LIGHT BRACKET WAS CRACKED AND BROKEN. IT IS BELIEVED THAT LNDG AND RUNNING OVER THE ARRESTING CABLE IS WHAT BENT THE NOSE LNDG GEAR DOWNLOCK BRACE. ALSO NOTE THAT AFTER TALKING TO YUMA TWR, THEY ACKNOWLEDGED THAT MANY GA ACFT LAND THERE AND THEY ARE DAMAGED BY RUNNING OVER THIS CABLE. IT IS NOW OUR COMPANY PROC TO NOT LAND AT ANY ARPT THAT HAS A CABLE UNLESS WE TOUCHDOWN BEYOND THE CABLE.
