Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain The New Piper Aircraft, Inc. (Piper) Model PA-46-500TP airplanes. This proposed AD would require you to replace all electronic control modules in the airplane electrical system with newly designed modules. This proposed AD is the result of reports of smoke in the cockpit and loss of electrical systems function. We are issuing this proposed AD to prevent short circuit failure and electrical arcing of the electronic control modules, which could result in loss of the electrical systems components or burning of wiring insulation and cause smoke in the cockpit. Such a condition could lead to the inability to properly control the airplane.
