The Air Force's 423rd Supply Chain Management Squadron at Tinker AFB, Oklahoma is doing market research to find companies that can newly manufacture a mechanical transmission (P/N NF53300-04A) for the B-1B bomber. This is a sources sought notice, not a solicitation, and it will help decide whether the buy is competitive or set aside for small business. The estimated need is 46 units (11 minimum, 69 maximum).
Watch out for
- Source approval may be at your cost. If you are not already an approved source, you may have to pay the engineering costs to qualify, which can be large for a small business.
Potential sources may be responsible for nonrecurring engineering costs associated with becoming an approved source.
- Complex aircraft component. A B-1B transmission needs precision manufacturing, testing and supply chain management that many small shops do not have.
- Market research only. No contract will come directly from this notice, and there is no funding for your response.
The government does not intend to award a contract on the basis of this market research.
