STC Request Form

The B&C Starter for Lycoming engines is the original lightweight alternative. Introduced over 15 years ago, this same design has provided dependable service for thousands of satisfied customers—and it remains the benchmark of reliability and genuine value.

When the B&C Starter was introduced, the typical OEM starter for 4- and 6-cylinder engines weighed 17.2 lbs. (and the OEM unit for 8-cylinder engines tipped the scales at 34.5 lbs!). In contrast, the B&C Starter weighed only 10.2 lbs. and eliminated the troublesome Bendix drive—all while providing greater torque than either of the OEM units.

Of course, other lightweight starters have joined the market since then, and there are cheaper starters to be had. But that cuts both ways. Proven reliability offers a better value in the long term—and that is B&C's specialty. The B&C Starter features sealed Heavy-Duty Ball Bearings (no bushings or needle bearings), All Metal Gears (no plastic gears of any kind), Electro-Mechanical Pinion Actuation (no Bendix drive), and an Efficient Series-Wound Motor (no permanent magnet motor).

The B&C Starter is available in a number of configurations to fit varied applications. STC/PMA approved on Lycoming O-235 through IO-720 engines, with models available for homebuilt aircraft, as well. All feature the same uncompromised value and unmatched reliability upon which B&C has built its reputation. Ask anyone who has one and they'll tell you: nothing else measures up to a B&C.

The B&C Starter for Lycoming engines is available in 8 configurations for experimental aircraft to suit a variety of applications (see table below). Configuration options include—12 or 24 volts; 122 or 149 ring gear teeth; standard- or counter-rotating. All feature the same “No Compromises” construction that has made the B&C Starter the benchmark of long-term reliability and genuine value.

NOTE: You may need to modify the support bracket (if used) that links the starter and alternator.

NOTE: For Robinson R22 or R44 helicopters, please be advised that the white solenoid jumper on the BC315 is not used. Consult the applicable wiring diagram in the Robinson Maintenance Manual for further information.

Beautifully machined case. Looks very sturdy we’ll see. Was a very tight fit on our AEIO-360A1D. The mounting flange makes it difficult to install the nuts on the mounting studs. You need to wiggle the starter in a bit at a time.

The problem have now is the bracket from the starter to the alternator does not fit. So do we now need to buy a B & C alternator?

Nice new starter. Came in an appropriate amount of time. Good packaging. Maybe sending some free stickers with orders would be cool, especially when spending over 700$ on one item!

After 2 Skytec 149-12LS starters and 2 additional replacement solenoids, I decided to try a B&C starter - based on their reputation for excellent products. It is working as advertised.

Far and away this starter was preferred by the group that flies canard airplanes like mine. It seems to use much less battery with more cranking power due to the design. My old starter was an inline version with no solenoid so the install took a great amount of time for the baffle mods.

Incredible quality, great design. Far better than the competition.

Top quality and design, lightweight and easy to install. I have installed/owned many B&C products and have never had any problems. Im an A&P/pilot and refer B&C to other mechanics and pilots without hesitation.

I gave it 4 stars because of a fit issue which applies to Piper PA-28-140 planes with a front-mounted oil cooler. The oil cooler needs to be remounted at least 1/2 to the outside of the baffle to avoid touching the solenoid mounted on the side of the starter. I fabricated a bracket that moves the cooler .6 outboard to avoid hitting the starter and .75 inwards to avoid hitting the nose bowl. Not an easy fix, but the starter works great and I was able to use a 2 AWG cable instead of 0 AWG cable for power.

The starter works as advertised. My only complaint is that the old starter cannot be returned for a core charge credit.
