What is an EA?

• A. Engineering Assessment
• B. Engineering Authorization. special permission per the engineer to do a repair / modification
• C. External Approval
• D. Environmental Adjustment

Answer: (B)

Engineering Authorization is a formal approval that comes from the engineer, granting permission to perform a repair or modification. This ensures any change is reviewed for safety, compatibility, and how it affects performance, and it sets clear limits on what can be done, what needs to be tested, and what documentation is required. The idea is not just to evaluate or approve actions after the fact, but to authorize the specific repair or modification up front under engineering oversight.

Other options don’t fit the concept. Engineering Assessment would be about evaluating the repair, not granting permission. External Approval implies authorization from someone outside the engineering scope, which isn’t the defined term here. Environmental Adjustment is unrelated to engineering authorization and instead would pertain to environmental factors, not the act of approving a repair or modification.
