## Summary

We propose to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-46-350P and PA-46R-350T airplanes. This proposed AD would require an inspection to verify the 35-amp and 250-amp current limiters are installed in the proper locations and would require a correction to the installation if the current limiters are not installed in the proper locations. This proposed AD would also limit operation to "only under day visual flight rules (VFR)'' until the current limiter installation is inspected and corrected. This proposed AD results from three reports of incorrectly installed current limiters. We are proposing this AD to detect incorrect installation of 35-amp and 250-amp current limiters, which could result in failure of the 35-amp current limiter if installed in the 250-amp location. This failure could lead to a total loss of electrical power.
