Engineering Support Services - Commercial Derivative Aircraft

The United States Government is seeking a sole-source Indefinite-Delivery, Indefinite-Quantity (IDIQ) contract for Executive Aircraft Division Engineering Support Services under solicitation FA813426RB001, issued by the Air Force Life Cycle Management Center at Tinker Air Force Base, Oklahoma. The contract supports engineering services for critical military aircraft platforms including the VC-25A, E-4B, and C-32A, with services structured across a base period from February 2027 through January 2028 and up to three option periods extending through January 2031. Engineering tasks are delivered under both recurring and Non-Recurring Engineering (NRE) frameworks, governed by a Level of Effort (LOE) model with strict limits of 3,500 direct labor hours per year under Cost Plus Fixed Fee (CPFF) arrangements, and capped at 10 direct labor hours per individual project unless formally authorized. All work is to be performed primarily at Tinker AFB, with inspection and acceptance occurring at the destination as specified in each Task Order. Pricing for all line items remains open for negotiation, and no total contract value has been established, reflecting the IDIQ nature of the agreement with funding allocated at the Task Order level. Proposals must adhere to stringent administrative, financial, and compliance requirements, including submission of certified cost or pricing data, completion of the DFARS Proposal Adequacy Checklist, and detailed documentation of subcontractor engagements, including actual costs and labor hours from the top five sole-source subcontractors. The contractor is required to implement robust financial controls, prohibit cost-plus-percentage-of-cost subcontracts, and provide immediate notification of any legal claims or subcontractor disputes that may involve government reimbursement. Special contract clauses govern LOE execution, including procedures for acceleration, early exhaustion of hours, and strict definitions of allowable effort that exclude local travel, uncompensated work, and home-based labor without written approval. The government retains full oversight rights to audit subcontracting practices, conduct assist audits, and review all subcontract negotiation memoranda. Invoicing must be processed exclusively through Wide Area WorkFlow (WAWF), and all deliverables require submission of DD Form 250 and Certificate of Conformance per FAR clauses. Proposals are due by 5:00 PM Eastern Time on May 18, 2026, with no formal evaluation factors or award basis disclosed, though compliance with technical, cost, and administrative requirements
