Flight data indicates that isolated battery starts in extreme cold weather degrade transient voltage, resulting in failed or hot engine starts.
The objective of this effort is to modify the aircraft to parallel the main and auxiliary batteries during start sequences to prevent engine damage in austere environments.

How to bid on this
This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.
- Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
- Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
- This listing has no set-aside restriction ("full and open competition"), meaning any business, large or small, can bid.
- Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
