Alternator for PA-18/19 (STC-PMA)

B&C Specialty Products is pleased to announce that we have received FAA STC-PMA approval for installation of the BC400 Alternator System on all PA-18/19 aircraft in both the “Standard” and “Restricted” categories.  The BC400-2 Alternator weighs 6.1 lbs., and features the same “no-compromises” design and construction that has been our hallmark for 27 years—a precision-balanced rotor; sealed heavy-duty ball-bearings; three solid attachment points; two built-in cooling fans; and provision for aircraft-style, external regulation. The BC201-1 Controller/Regulator combines “quiet” linear voltage regulation with solid-state over-voltage protection, and low-voltage sensing/warning. Ships with alternator mounting brackets for either Boss or Case mount engines, attachment hardware, belt tension arm, and belt.

An expanded installation electrical package—adding wire, ring terminals, circuit breakers, and an “ON-OFF” toggle switch to the previously mentioned items—is also available for aircraft requiring an “upgrade” of existing electrical components.

Note: This installation applies to aircraft with previously existing electrical systems, and oil coolers mounted on the aft engine baffle only. Aircraft otherwise equipped will require field alteration and FAA approval; or modification per previously existing STC.

When ordering, please complete the STC Request Form and submit to B&C Specialty Products for issuance of STC paperwork.
