BC410
|
|
|

B&C Specialty Products is pleased to announce that we have received FAA STC/PMA approval for installation of the BC410 Standby Alternator and matching regulator on Piper PA32, Cherokee Six, Lance and Saratoga aircraft (14 or 28 volt) as the standby electrical system. Click for eligible serial numbers.
Prices for the various components are as follows:

|
| BC410 & Regulator (14v or 28v) w/STC |
$2200 |
| Installatioin Kit |
$435 |
|
The standby system provides 20 amps of power to support continued flight in the event of primary alternator failure. It operates automatically, annunciating its operation to the pilot through a panel mounted annunciator which doubles as a standby alternator load monitor.
If the primary alternator fails in flight, the standby regulator will sense the drop in system voltage and automatically activate the standby alternator. If the current requirement is over 20 amps when the standby alternator is activated, the annunciator will flash. Reducing the current usage to 20 amps or less will cause the annunciator to cease flashing and light steadily. The pilot may choose which equipment he needs for the given flight conditions by simply keeping the total load below the flashing point of the annunciator. This will reserve battery energy for transient loads (gear, flaps, landing lights, etc.)during approach. Loads may be beyond the flashing point of the annunciator for up to 5 minutes without damaging the standby alternator.
On aircraft with O-540-E4B5, IO-540-K1A5,or IO-540-K1G5 engines, a Lycoming hydraulic pump drive adapter must be purchased separately and installed on the accessory case. The vacuum pump is moved to this new location to allow the standby alternator to be installed on the vacuum pump accessory pad. On IO-540-K1A5D and IO-540-K1G5D engines, the accessory case must be removed and an accessory drive gear installed in the existing machined accessory drive pad. The Standby alternator is installed in this location and the vacuum pump need not be moved.
Panel mounted equipment includes a STBY ALT ON annunciator and two standard pull type circuit breakers (1 amp and 5 amp). The STBY ALT master switch is purchased separately from Piper to match the existing rocker type switches. Appropriate placards are provided for each panel mounted device. The regulator is mounted between the instrument panel and baggage compartment or in the baggage

For individuals interested in obtaining one-time field approvals on aircraft not yet covered by the STC, a general wiring diagram has been provided to assist in these efforts. We will continue f time, money and paperwork is required to obtain these STC's. Please, let us know if you are interested in the standby alternator system for your aircraft and feel free to call if you have questions.

Instructions for Continued Airworthiness
for
B & C Specialty Products Model BC410 & BC425 Alternators
|
|
|
The B&C Model alternator requires no recurrent maintenance during its service life of 1700 Hours. It is recommended that at 1700 hours or less time in service or during engine overhaul the alternator be returned to B&C Specialty Products for factory overhaul.
At each Annual or 100 hour inspection required by the FAA, check the alternator externally for security of mounting and wiring and perform the before takeoff test described under the "Normal Procedures" section of the Airplane Flight Manual Supplement;. Alternately, the Final Test described in the installation drawing may be used for this test.
Failure due to broken wires or damaged connectors may be corrected in the field using repair procedures complying with the latest revision of AC43.13-xx. All other repairs are by replacement only.
IF THESE UNITS ARE NOT BEING INSTALLED UNDER AN STC, THEY MUST BE ACCOMPANIED BY A ONE TIME FIELD APPROVAL FOR USE ON A TYPE CERTIFICATED AIRCRAFT.
