I just came across information on another forum that the FAA has issued an Unapproved Parts Notification letter against Ameri-King Corporation.

"The Federal Aviation Administration (FAA) has determined Ameri-King Corp., located at 17881 Sampson Lane, Huntington Beach CA 92648, manufactured, sold or distributed parts and articles for installation on FAA type certificated aircraft, which did not conform to an approved design, but were represented as FAA approved."

The FAA letter can be found here: http://www.faa.gov/aircraft/safety/p...13NM460018.pdf

The landing page for Ameri-King indicates the web site is temporarily closed??? http://www.ameri-king.com/

It appears at the moment that any products manufactured by them after Dec 28, 2015 cannot be installed on type certified aircraft. Further, the FAA is investigating older products and may issue an Airworthiness Directive if they are found to be unsafe.

This could turn out to be another gotcha for a lot of us. I've just got their SK 350 encoder, but a lot of folks have one of their ELT's.
