Narrative:
Climbing through 8000 ft we heard a loud popping sound from first officer's window. At each additional psi, the popping became louder. We returned to iah. Callback conversation with reporter revealed the following information: reporter captain doesn't know what caused the popping in the first officer's windshield. He says that it was loud, like a .22 shot, and increased frequency as the cabin pressure increased. There were no indications of any kind which could lead to troubleshooting, so flight crew returned to land at their departure airport. Maintenance apparently found no problem and the aircraft was redispatched with the same flight crew and the problem didn't recur.

Title: ACFT EQUIP PROB. WINDSHIELD POPPING. FREQ OF POPPING INCREASED WITH PRESSURE INCREASE. FLC RETURNED TO DEP ARPT.
Narrative: CLBING THROUGH 8000 FT WE HEARD A LOUD POPPING SOUND FROM FO'S WINDOW. AT EACH ADDITIONAL PSI, THE POPPING BECAME LOUDER. WE RETURNED TO IAH. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR CAPT DOESN'T KNOW WHAT CAUSED THE POPPING IN THE FO'S WINDSHIELD. HE SAYS THAT IT WAS LOUD, LIKE A .22 SHOT, AND INCREASED FREQUENCY AS THE CABIN PRESSURE INCREASED. THERE WERE NO INDICATIONS OF ANY KIND WHICH COULD LEAD TO TROUBLESHOOTING, SO FLC RETURNED TO LAND AT THEIR DEP ARPT. MAINT APPARENTLY FOUND NO PROB AND THE ACFT WAS REDISPATCHED WITH THE SAME FLC AND THE PROB DIDN'T RECUR.
