Narrative:

On jan/thu/02, I was the captain on a giv flight from the mainland to sju. We had been handed off from approach control to sju tower. Sju tower cleared us to intercept localizer runway 10 and to land runway 8. We thought tower cleared us to intersect localizer 8 so we read back 'localizer 8.' then tower said, 'no, localizer 10.' a few mins after that, tower called for us to fly localizer 10 and cleared us to land runway 8. We rogered the call. About this time, the copilot's windshield shattered with a very loud bang. We both ducked. Then when we saw that the windshield had shattered and we felt the windshield to determine if it was the inside windshield or the outside windshield, it was the outside. This took a few mins, but I had already intercepted localizer 10 and was flying it. I told the copilot to read the land check first since we were well into the approach. I did not want to do the windshield failure checklist properly and then land with the gear up. So the copilot and I did the landing checklist. Then I continued to fly localizer 10 while the copilot found and performed the windshield failure checklist and I monitored. When the copilot finished the checklist, we were well into the landing phase. The copilot picked up his normal callouts and we continued and landed. We did not realize that we had landed on the wrong runway until tower told us that we were cleared to land on runway 8 and that we had landed on runway 10. After we taxied in, I called the tower supervisor and explained what had happened. The tower supervisor listened to the tapes and came over and inspected the aircraft. The tower said that nothing dangerous had happened. That tower had called us twice to verify that we were going to land on runway 8 and when tower got no response that they determined that we were going to land on runway 10. Due to the excitement in cockpit and the reading of the checklist, we never heard the last 2 calls from tower. I have flown to sju about 6 times in the last 20 yrs and I have always landed on runway 10 and taken off on runway 8. I feel that I did right in having the landing checklist read first, since this prevented the compounding our problem. However, I should have stated the duties of each pilot. I should have said that I would fly the airplane and handle the radios and for the copilot to do the checklist. What happened is that the communications with ATC were not performed by anyone. Had I assigned the communications to someone then we would not have missed tower's 2 calls and we could have communicated our situation to tower and requested to land straight-in runway 10.

Title: A GLF4 CREW, ARRIVING TJSJ, LANDED ON THE WRONG RWY, AFTER HAVING THE FO'S WINDSHIELD SHATTER.

Narrative: ON JAN/THU/02, I WAS THE CAPT ON A GIV FLT FROM THE MAINLAND TO SJU. WE HAD BEEN HANDED OFF FROM APCH CTL TO SJU TWR. SJU TWR CLRED US TO INTERCEPT LOC RWY 10 AND TO LAND RWY 8. WE THOUGHT TWR CLRED US TO INTERSECT LOC 8 SO WE READ BACK 'LOC 8.' THEN TWR SAID, 'NO, LOC 10.' A FEW MINS AFTER THAT, TWR CALLED FOR US TO FLY LOC 10 AND CLRED US TO LAND RWY 8. WE ROGERED THE CALL. ABOUT THIS TIME, THE COPLT'S WINDSHIELD SHATTERED WITH A VERY LOUD BANG. WE BOTH DUCKED. THEN WHEN WE SAW THAT THE WINDSHIELD HAD SHATTERED AND WE FELT THE WINDSHIELD TO DETERMINE IF IT WAS THE INSIDE WINDSHIELD OR THE OUTSIDE WINDSHIELD, IT WAS THE OUTSIDE. THIS TOOK A FEW MINS, BUT I HAD ALREADY INTERCEPTED LOC 10 AND WAS FLYING IT. I TOLD THE COPLT TO READ THE LAND CHK FIRST SINCE WE WERE WELL INTO THE APCH. I DID NOT WANT TO DO THE WINDSHIELD FAILURE CHKLIST PROPERLY AND THEN LAND WITH THE GEAR UP. SO THE COPLT AND I DID THE LNDG CHKLIST. THEN I CONTINUED TO FLY LOC 10 WHILE THE COPLT FOUND AND PERFORMED THE WINDSHIELD FAILURE CHKLIST AND I MONITORED. WHEN THE COPLT FINISHED THE CHKLIST, WE WERE WELL INTO THE LNDG PHASE. THE COPLT PICKED UP HIS NORMAL CALLOUTS AND WE CONTINUED AND LANDED. WE DID NOT REALIZE THAT WE HAD LANDED ON THE WRONG RWY UNTIL TWR TOLD US THAT WE WERE CLRED TO LAND ON RWY 8 AND THAT WE HAD LANDED ON RWY 10. AFTER WE TAXIED IN, I CALLED THE TWR SUPVR AND EXPLAINED WHAT HAD HAPPENED. THE TWR SUPVR LISTENED TO THE TAPES AND CAME OVER AND INSPECTED THE ACFT. THE TWR SAID THAT NOTHING DANGEROUS HAD HAPPENED. THAT TWR HAD CALLED US TWICE TO VERIFY THAT WE WERE GOING TO LAND ON RWY 8 AND WHEN TWR GOT NO RESPONSE THAT THEY DETERMINED THAT WE WERE GOING TO LAND ON RWY 10. DUE TO THE EXCITEMENT IN COCKPIT AND THE READING OF THE CHKLIST, WE NEVER HEARD THE LAST 2 CALLS FROM TWR. I HAVE FLOWN TO SJU ABOUT 6 TIMES IN THE LAST 20 YRS AND I HAVE ALWAYS LANDED ON RWY 10 AND TAKEN OFF ON RWY 8. I FEEL THAT I DID RIGHT IN HAVING THE LNDG CHKLIST READ FIRST, SINCE THIS PREVENTED THE COMPOUNDING OUR PROB. HOWEVER, I SHOULD HAVE STATED THE DUTIES OF EACH PLT. I SHOULD HAVE SAID THAT I WOULD FLY THE AIRPLANE AND HANDLE THE RADIOS AND FOR THE COPLT TO DO THE CHKLIST. WHAT HAPPENED IS THAT THE COMS WITH ATC WERE NOT PERFORMED BY ANYONE. HAD I ASSIGNED THE COMS TO SOMEONE THEN WE WOULD NOT HAVE MISSED TWR'S 2 CALLS AND WE COULD HAVE COMMUNICATED OUR SIT TO TWR AND REQUESTED TO LAND STRAIGHT-IN RWY 10.
