Challenge: This material specified a requirement to use 7075-T73 aluminum per AMS-QQ-A200/11
Solution: A more common aerospace aluminum is 7075-T7351 per AMS-QQ-A-225-9. After several searches for the originally specified material a request was made to allow an alternate material.
Result: The alternate material was approved, providing an easier supply chain channel for acquiring the material. As a result this change provides a lead-time reduction for the customer and this recommendation can be applied to various similar designs.
