FAA-PMA N300 Mooney Replacement & Upgrade Alternators New National N300 12 VOLT 70 and 100-AMP Retrofit Alternators for Mooney Aircraft

Neat and Clean National 100-Amp N300 Installation is an Easy Upgrade(24 volt 70 and 85 AMP versions also available.)
Scores of Mooney operators have already upgraded to the National N300 70 amp direct retrofit alternators, benefiting from increased output at normal engine operating speeds, much lower radio noise and a marked increase in overall reliability. For Mooney operators demanding the ultimate in power handling capacity, National produces an ultra-heavy duty 12 volt 100 amp FAA-PMA small case version of the National N300. This replacement for 60 and 70 amp OEM Prestolite alternators allows Mooney owners to replace their anemic, tired and much-overhauled alternators with the most powerful alternator available for their aircraft.

All Heavy Duty National alternators are approved as direct replacements for lower-powered OEM units, with no wiring or voltage regulator change required. Most operators obviously elect to perform a simple wiring upgrade on the aircraft system, allowing full benefit of the N300’s much improved power generating capacity. Under all normal operating conditions, the higher current capability of the National alternator translates into increased performance margins, cooler operation and greatly extended service life, compared to the OEM 60-70 amp alternators. The enhanced design of the National N300 also provides much smoother operation, lower vibration and increased clearances in the engine compartment. The N300 also boasts a weight savings over most of the OEM units.

National 100-Amp N300 Installation; Alternator in "Lycoming Gray" OEM ConfigurationThe National Mooney retrofit alternators are built to critical standards of fit, finish and performance, using premium quality components specified for aircraft use applications. Critical electrical hardware is stainless steel, and cases are of a special corrosion resistant finish. During manufacture, emphasis is given to precision-balance the rotor for ultra-smooth operation at high speeds, and extensive radio suppression measures are incorporated into the basic alternator design. This results in an extremely quiet, long-life alternator capable of the performance demanded by today’s high electrical use requirements.

Note for operators of early model GENERATOR EQUIPPED Mooney aircraft:

National has alternator upgrade kits for BOTH the WIDE and NARROW DECK engine Mooney aircraft which are presently equipped with generators. The National installation is presently in the process of STC, along with many other aircraft upgrade applications. Until the National STC is completed, these kits ARE available for individuals wishing to install them via Field Approval.

Parties interested in securing Field Approval installation of these alternator upgrade kits should contact National AirParts, Inc., for copies of previously approved FAA Field Approvals.

Warranty for all new National AirParts alternators remains at the industry-setting standard of 2 years or 600 operating hours.
