This is the ULTIMATE electrical power upgrade for these aircraft — and with a choice of either the 70-Amp or the ONLY lightweight 100-amp small-case alternator available!

*NOTE: OEM ammeters should be replaced by an ammeter or loadmeter of sufficient capacity when choosing either the 70 or 100-amp installation configuration.

Kits are complete with detailed installation instructions. Copies of of previously-approved FAA Field Approvals may be available to help secure local FSDO installation approval.

Warranty for the 100-Amp alternators in this kit, as with all National AirParts alternators, remains at the industry-setting standard of 2 years or 600 operating hours. Factory Rebuilds are available from the National manufacturing facility.
