Newly manufactured National N400 High Power Aircraft Alternators are ideal for those requiring maximum power — with reliability FAR GREATER than OEM AIRCRAFT ALTERNATORS. The National N400 uses the approximate dimensions and style of typical Ford/Teledyne large case alternators in order to maintain compatibility and fit — but this heavy duty unit is engineered and manufactured by National AirParts. With premium aircraft-grade construction and components, this alternator, in 100-200 amp output configurations, is ideal for those operators demanding heavy, continuous electrical output.

These PREMIUM QUALITY National AirParts N400 heavy duty alternators are designed and manufactured for the most demanding General Aviation, CUSTOM and SPECIAL PURPOSE applications. They are presently FAA-PMA’d and are used by O&N Aircraft in their STC #SA01437NY for the Cessna 210-Series Aircraft.

Alternator models are available to custom fit most engines utilizing either belt-drive or gear-drive alternators.
