FAA PMA Certified Alternators
FAA PMA Certified Alternators
Plane-Power FAA PMA-certified alternators deliver reliable electrical power across the widest range of general aviation applications in the category. From direct-fit OEM replacements to high-output units for turboprops and UAVs, every series is engineered for modern performance, lightweight construction, and long-term reliability. All models are FAA PMA-approved and available factory-direct through Hartzell Aviation.

Prestolite Style
Prestolite originally developed this alternator style, but Plane-Power has continued to refine and improve the designs. These are widely used in legacy OEM applications. Many are PMA-approved as identical, direct-fit replacements for the OEM part numbers.

ES Series
The ES Series was developed internally by Plane-Power to provide customized solutions for OEM applications, as well as new PMA-approved alternatives to Ford, Chrysler, and CMI/Crittenden units. ES Series aircraft alternators are OEM-approved for a range of general aviation applications, including piston aircraft, single-engine turboprops, and single-engine light jets. In addition, lightweight/high-power-density ES Series alternators are seeing extensive use on UAV applications.

ASG Series
ASG Series alternators were originally developed by Aero Electric and are OEM on several Cessna applications and PMA replacements for out-of-production 24V Ford alternators. The ASG aircraft alternator designs incorporated several improvements over the Ford alternators they replaced.

AL Series
The original Plane-Power alternators are modern, lightweight replacements for OEM alternators. While not direct-fit replacements, they come with the mounting hardware needed to make the switch.

C/E Series
Like the AL Series, these are modern, lightweight replacements for OEM alternators, but the C/E Series are direct drive for use on Continental engines.

Jasco Series
Jasco alternators were originally developed by Skytronics to support legacy aircraft, supplanting older generators. There are several STC generator-to-alternator conversions, as well as PMA-approved aircraft alternators for many aircraft with vintage engines.
