SAO PAULO (Reuters) -Brazilian planemaker Embraer delivered 57 non-defense aircraft in the third quarter, up 33% from a year earlier, it said on Friday.

The world's third-largest planemaker delivered 16 commercial and 41 executive jets in the quarter ended in September.

In a securities filing, Embraer said its firm order backlog reached $22.7 billion at the end of September, a nine-year high.

The company, which also delivered two defense aircraft in the quarter, is expected to release full third-quarter earnings on November 8.
