(Corrects year-earlier profit in paragraph 1 to 124 mln reais, not 62 mln reais)
SAO PAULO, July 25 Brazil's Embraer SA , the world's third-largest commercial planemaker, posted a second-quarter net loss of 10 million reais ($4.5 million), down from a profit of 124 million reais a year earlier, according to a Thursday securities filing.
The result missed an average estimate of an $88 million profit in a Reuters survey of seven analysts. Analysts gave their estimates in dollars, but Embraer's initial earnings report was in Brazilian reais.
