Preheat the oven to 350°F.
In a large mixing bowl, add your flour, baking powder, baking soda, cinnamon and salt. Whisk that together until thoroughly combined.
In a separate mixing bowl, mash your ripe bananas. Add the eggs, sugar and oil, and whisk until combined.
Add the dry ingredients to your wet ingredients and fold everything together until just combined. Add your shredded zucchini and pecans to the batter and fold together.
Grease two separate 9x5 loaf pans. Separate your batter into the loaf pans.
Bake for about 40-50 minutes. Check doneness by inserting a toothpick into the center of the bread. If it comes out clean, remove the bread from the oven. Let them cool in the pans for 10 minutes before removing them and letting them cool completely on a wire rack.
