The airport has been troubled by slippery runways and has had several accidents where water accumulation has been a significant factor , the most notable being the one involving TAM Airlines Flight 3054 on 17 July 2007 : although the main runway had been repaved in June 2007 , its new rainwater drainage grooves were only finished in September 2007 . As a consequence of this accident and the subsequent public outcry for better safety performance and noise reduction , the airport 's operations were significantly altered , through restrictions in the number of landing slots , flight distances , and operating times ( presently from 6:00 to 22:30 hours ) . Furthermore , the maximum allowable gross weight of aircraft was reduced
