In a large bowl, combine the flour, baking soda, baking powder, 1 teaspoon cinnamon and salt. In a small bowl, whisk the eggs, 1-1/2 cups sugar and oil. Stir in apples; let stand for 5 minutes. Stir into dry ingredients just until moistened. Fold in pecans.
Pour into two greased and floured 8-in. x 4-in. loaf pans. Combine remaining sugar and cinnamon; sprinkle over batter. Bake at 350° for 50-60 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks. Yield: 2 loaves (12 slices each).
