## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

It was found one occurrence of a fuel booster pump circuit br[e]aker opening during an engine maintenance servicing. An inspection inside the fuel tank revealed the fuel booster pump[']s electrical harness chafing against its body, causing the loss of the electrical wiring protection and resulting in a short circuit. Further in-tank inspections have showed other fuel booster pump electrical harnesses chafing either with the pump body and/or with adjacent fuel lines, causing damage to the harness protective layers and resulting * * * [in a] possible ignition source inside the fuel tank.

* * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
