Weight and Balance: Starter

[mooniac58]

Hello mooniacs!

I have a question for anyone who might know the answer...

I upgraded to a SkyTech lightweight starter and need to adjust the W&B - does anyone know from experience what the moment would be of the starter?

Thanks!

Craig

Weight x Arm = Moment, does it not? Assuming the Arm didn't change from the prior starter, there's your answer. But all that should be in the documentation for the starter and should have been completed by the A/P who installed it, I would think.

Call Stacey Ellis or Brian Kendrick on Monday.

The arm on a J should be the same as on an F, -23".  Not sure about the weight, though.

Sorry, I wanted to know the ARM to determine the moment.  I did see in my POH equip list it groups the engine, starter and alternator into one group with an arm of -15.76".

The airplane's type certificate data sheet has this information. You can download it from faa.gov.

Edit: Its -23.0" for the J per the TCDS, but check for yourself
