The Department of Transportation (DOTr) and the Ninoy Aquino International Airport (NAIA) officials have not learned from past mistakes, Senator Grace Poe said. Poe said the power outage at the NAIA Terminal 3 today, Monday, May 1, shows another disruptive failure of the airport systems causing grave inconvenience to travelers.. ‘’The lack of functioning air conditioners in several parts of the airport is not only troublesome but could even be precarious to health especially of the elderly,’’ Senator Grace Poe, chairwoman of the Senate public services committee, said. Hindi katanggap-tanggap na tuwing may brownout, maaantala ang buong sistema ng airport at ang byahe ng publiko (This is not acceptable that each time a power brownout takes place, the whole system at the airport is affected and It affects the traveling public),’’ she said. ‘’Parang di natututo ang DOTr at NAIA sa mga nauna nitong kapalpakan (As if DOYTr and NAIA have not learned from their past mistakes),’’ she added. Senator Jinggoy Ejercito Estrada asked airport officials: ‘’Hindi pa ba tayo nadala (haven’t you learned)?. To the concerned aviation and transportation officials, have you had not enough yet?’’ ‘’We’ve been in this situation last New Year’s Day and it was even worse. This power outage could have been avoided if the necessary measures are already in place, at least in having an uninterruptible power supply considering the thinning of power supply this summer season and when demand usually peaks,’’ he said. Estrada said that the Senate Committee Report No. 39 already identified the absence of redundancy or systems backup as among the critical reasons that led to the airport shutdown last January 1 along with the issue of lack of real maintenance to the airport equipment. ‘’That would have been enough for our concerned officials to be on the lookout for situations like what we’re having now in NAIA Terminal 3,’’ he pointed out. Estrada said this second incident this year fell on a holiday, Labor Day, where many travelers went to the airport. ‘’Panawagan sa ating mga concerned agencies: Maawa naman po kayo sa ating mga kababayan. Suklian naman natin ng nararapat na serbisyo ang mga binabayad nilang buwis (To our concerned agencies: Please pity our countrymen. You should repay the taxpayers with good service),’’ he said.
