RepairMaps can help you stay on top of aircraft corrosion, reduce CPC Level 2 findings at your heavy check events
Aside from the obvious, high-level advantages of using RepairMaps to manage your structures data, there are many small, less-than-obvious use cases where the RepairMaps system packs a lot of value.
This came to mind again as I recently processed a corrosion blend-out (DACS) item on behalf of a client. The item was classified as a DACS/ReBlend due to the fact that the RepairMaps system showed a history of previous corrosion blend activity on the structural member at hand.
By reviewing the appropriate map graphic in the RepairMaps system, I could easily see that there were previous Tracked Items in the form of corrosion blends already recorded for this same condition on the same structural element. While setting up the new Tracked Item to record the new blend activity, selecting the Re-Blend SubType (on Wizard Screen 1) launches the TI supersession interface automatically, and you can then select any other corrosion blend TIs on the structural element that may have been impacted by the new blend activity. According to the Corrosion Control document, a corrosion finding that would apparently meet the definition of a Level 2 corrosion finding which can be attributed to a series of level 1 blends over successive inspections can be classified as a Level 1 blend.
Staying on top of this type of blend activity allows RepairMaps users to reduce their Level 2 corrosion findings. For example, for the specific structural member under discussion, when we are forced to replace it, (as is fairly common), we can still claim CPC Level 1 corrosion since we can demonstrate a series of Level 1 Blends, (all documented in RepairMaps), that led to the replacement. Having the data regarding the previous blend activity instantly available to us at the heavy check allowed us to quickly make this determination and classify the item properly.
Reducing the number of Level 2 findings saves everyone time, reporting hassles and the very real potential of having to adversely adjust your inspection program to accommodate recurring Level 2 finds.
