Piper Aircraft, Inc. Models PA-46-350P and PA-46R-350T Airplanes
This AD applies to the following airplane models and serial numbers that are certificated in any category:
| Models | Serial Nos. |
|---|---|
| PA-46-350P | 4636375 through 4636447. |
| PA-46R-350T | 4692001 through 4692068. |
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-46-350P and PA-46R-350T airplanes. This AD requires you to inspect the 35-amp and 250-amp current limiters to verify they are installed in the proper locations and correct the installation if the current limiters are not installed in the proper locations. This AD also limits operation to "only under day visual flight rules (VFR)" until the current limiter installation is inspected and corrected. This AD results from three reports of incorrectly installed current limiters. We are issuing this AD to detect and correct 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.
To address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Insert the following into the Limitations section of the airplane flight manual (AFM): “Operate Only under Day Visual Flight Rules (VFR).” You may remove the limitations specified in this paragraph after doing the action required in paragraphs (e)(2) and (e)(3) of this AD, as applicable | Before further flight after May 5, 2009 (the effective date of this AD). | Under 14 CFR 43.7, the owner/operator holding at least a private pilot certificate is allowed to insert the information into the AFM as specified in paragraph (e)(1) of this AD. You may insert a copy of this AD into the Limitations section of the AFM to comply with this action. Make an entry into the aircraft logbook showing compliance with this portion of the AD per compliance with 14 CFR 43.9. |
| (2) Inspect the 35-amp and 250-amp current limiters for installation in the proper location | Within 100 hours time-in-service after May 5, 2009 (the effective date of this AD). | Follow Piper Aircraft, Inc. Service Bulletin No. 2000, dated September 16, 2008. |
| (3) If you find any current limiter not in the proper location, reinstall the current limiter in the proper location | Before further flight after the inspection required in paragraph (e)(2) of this AD. | Follow Piper Aircraft, Inc. Service Bulletin No. 2000, dated September 16, 2008. |
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
