About this file
This document is a draft Request for Proposal Vendor Questions and Answers for the C-17 Data Recorder System (DBRS), a Line Replaceable Unit (LRU) procurement to retrofit the United States Air Force C-17 fleet with data bus recording capability. The requirement involves procuring 257 total LRUs: 222 for the USAF C-17 fleet, 12 for Boeing Avionics Integration Support Facility (AISF) and flight testing (7 LRUs plus 5 spares), and 3 kits plus 1 spare for the NATO Airlift Management Program. The DBRS must capture all data present across the C-17's data buses and fuel quantity computers. This is a Small Business Set Aside contract with anticipated RFP release no later than Q2 FY27, with contract award expected approximately 10 months after RFP release. Performance Review Units (PRUs) are anticipated to deliver approximately 6 months after contract award, with production quantities distributed across four lots: Lot 1 (August 2027), Lot 2 (March 2028), Lot 3 (December 2028), and Lot 4 (August 2029).
The Q&A addresses critical technical specifications including data bus protocols (MIL-STD-1553, ARINC 429, Ethernet-based systems), environmental qualification standards (DO-160, MIL-STD-810), cybersecurity requirements (NIST controls, RMF package, secure boot, and trusted computing for Controlled Unclassified Information), and storage requirements without data encryption. The system will use removable SSDs meeting SRD requirements and will only record unclassified data. The Government will provide wiring harness pinouts, interface control documents, and integration engineering drawings to offerors, with Boeing executing ASIS integration supported by the selected vendor. First Article Testing consists of CLINs 0001-0003 (preproduction units) with no additional FAT required beyond production acceptance testing. Contract terms specify FOB Destination with Fixed Firm Pricing for all CLINs, with production CLINs (X004-X006) inspected and accepted by the awardee's DCMA office. Technical proposals must include an Integrated Master Schedule as a key evaluation subfactor, with evaluation criteria weighting described on page 41 of the RFP. The Government will not provide simulation tools, test datasets, or ground data analysis software, but requires vendors to provide Technical Data Packages post-award and develop obsolescence management plans.

Draft DBRS RFP Vendor Questions
1. Technical Clarifications
1. Please confirm the specific data bus protocols installed across the C-17 fleet (e.g., MIL-STD-1553, ARINC 429, Ethernet-based systems) that the DBRS must capture.
Review attachment 10
1. What are the required data capture rates, storage capacity thresholds, and retention duration requirements?
Review attachment 10
1. Are there defined environmental qualification standards required (e.g., DO-160, MIL-STD-810, EMI/EMC thresholds)?
Review attachment 10
1. Will Government Furnished Information (GFI) include wiring harness design data packages and interface control documents?
Yes, the pinout and interface tray engineering drawings will be provided.
1. Is flight certification required prior to delivery of production LRUs?
Military Flight Release (MFR) should be approved prior to delivery acceptance of production LRUs
1. What are the cybersecurity requirements for the DBRS (e.g., RMF package, NIST SP 800-53 controls, Platform IT vs. PIT determination)?
Review SOW para 2.4.1
1. Will Boeing AISF integration documentation and lab interface specifications be made available to offerors?
Integration engineering drawings (i.e pinout and interface tray) will be provided to offerors. ASIP integration will be executed by Boeing, with support from the selected vendor (SOW para 2.5.1).
2. Contract & Evaluation Questions
1. Please clarify the relative weighting of Technical, Past Performance, and Price factors.
The relative weighted is described on pg 41. See screenshot.
1. Will relevant commercial aerospace data system integration experience be considered acceptable past performance?
No. The somewhat relevant definition in section M will be modified to state, “manufacturing of a databus recorder and/or other commercial solutions into a fleet aircraft as a prime/subcontractor that included direct or indirect support for test.” Since the vendor is not expected to integrate the DBRS, the integration experience will be deemed irrelevant.
1. Is First Article Testing anticipated beyond the preproduction test units identified in CLINs 0001–0003?
There are no initial testing requirements past the acceptance of CLIN 0001-0003. Production acceptance testing is required.
1. Can the Government provide anticipated production ramp timelines across the ordering periods?
Lot 1 (Aug 27), Lot 2 (Mar 28), Lot 3 (Dec 28), Lot 4 (Aug 29) – Quantities are unknown at this time.

· Should we assume a strict form-fit-function replacement? If not, where is there room for deviations from existing mechanical and electrical interfaces?
Review attachment 10 Q14 – Functional and Non-Functional Legacy Units
· Will functional and non-functional legacy units be available for comparative testing and form factor evaluations during the development phase?
As of date, the USG have not procured a databus recorder for their fleet. Therefore, there will be no legacy unit to reference for comparative testing.
Q15 – Preferred Vendors and/or Components
· Are there preferred vendors and/or components that would help reduce risk or impact to certifications?
No preferred vendors and/or components to reduce risk
Q 16 - Can the Government please clarify whether "flight hours" should also include operational hours on ground?
· For this requirement, flight hours includes any period that there is power to the DBRS Q 17 - This implies that the DBRS will stop writing data if storage capacity is reached. Is that the desired behavior?
· Yes, this is the desired behavior.
Q 18 - Does this imply that the DBRS shall have 2 power inputs? Or will the DBRS be installed on a bus with emergency power?
· The DBRS will have only one power input which shall abide by SRD 2-1.
Q 19 - Will alternate 6 pin connectors that appropriately mate with the power connector be satisfactory?
· No.
Q 20 - Does "shut-off" mean power off of the LRU or stopping data recording?
· Power off of the LRU Q 21 - Can the Government clarify the encryption requirements?
· Encryption requirements outlined in Documents, Drawings and Publications, SRD 2.2.2 Q 22 - Can the Government clarify if "volatile memory" should be "non-volatile memory"?
· Volatile memory storage should be sanitized IAW NIST SP 800-53 rev 5 Q 23 - Will alternate 128 pin connectors that appropriately mate with the aircraft harnesses be satisfactory?
· No.
Q 24 - Can the government clarify this requirement and identify where the data will be transferred to?
· Data transfer requirements shall meet SRD requirements (SRD 8-1).
Q 26- Please provide the Government’s anticipated acquisition timeline, including the expected proposal due date, anticipated contract award date, and planned timing of the lead-time event referenced in the delivery schedule.
· The proposal due date is TBD due to changes in source selection guidance AF wide. Key contract dates will be provided once the RFP is officially released. We expect the PRU’s to be delivered ~6 months after contract award based on our market research. Your IMS should highlight the optimal timelines your company can deliver.
Q 27- Can the Government specify inspection and acceptance provisions for production deliveries? CLINs X004-X006 are production CLINs and will be inspected and accepted by awardee's DCMA office. The specific DCMA location will be provided once contract is awarded. The inspection and acceptance are guided by RFO 52.212-4(b).
Q 28- Will the Government consider FOB Origin for all CLINs? FOB Origin is more in line with commercial organization practices and allows for small businesses to more easily recognize revenue. If not, how should potential offerors address the cost of transportation included in the pricing spreadsheets? No, FOB cannot be Origin for all CLINs. There will be no evaluation of transportation costs for FOB Origin. FOB Destination costs shall be included in the FFP.
Q 29- Several of the Special Clauses have “Deviation” listed but no actual deviation number next to them. Can the Government provide the specific deviations to be used? This is due to the Revolutionary FAR Overhaul (RFO) as part of the President’s Executive Order. Currently all RFO clauses are deviations for now. See link for more information: https://www.acquisition.gov/far-overhaul.
Further, will the Government consider tailoring FAR 52.212-4 to be more in line with commercial practices and so they align/do not conflict with the specifications and requirements. Specifically, tailoring should pertain to inspection/acceptance, indemnities, risk of loss, title, and warranty areas. Yes, clauses could be tailored to align commercial practices and specific requirements. The USG would need specific instances as we are unaware of any conflict with specification of requirements. The other areas that are not dealing with requirement or specification are written to be so broad at RFO level as to no conflict with commercial requirements.
Q 30- Will Contractors be required to respond to a USG RFQ or RFP before issuance of delivery or task orders, due to fluctuating quantities? Yes, this process ensures compliance with "fair opportunity" regulations, allowing the government to evaluate the best technical approach and price for specific, fluctuating needs. This draft RFP represents FFP prices for all years which the USG may order from and a single award will be made.
Further, can a Contractor “no-bid” or turn down an order in accordance with 52.216-19 during the period of performance? Yes, a contractor may "no-bid" or decline an order under FAR 52.216-19 if the order exceeds the maximum order limitations specified in the contract. The contractor must return the order within a specified number of days (usually 5–7 days) with written notice stating their intent not to ship the items and the reasons for declination. In most cases, this would allow the Contractor to negotiated additional lead time for quantities in excess of limitations rather than rejection.
Q 31- What will the IDIQ minimum? Will it be the base amounts described in the pricing sheet? The minimum order is defined clause RFO 52.216-19 Q 32- Will PIEE have the ability to accept both a .pdf and a Word copy? Or does the Government expect just a Word copy of the technical proposal to be transmitted? Yes, the Procurement Integrated Enterprise Environment (PIEE) application supports both PDF and Microsoft Word document formats.
In what format does the Government wish to receive the Subfactor Two Integrated Master Schedule - can it be screenshots of MS Project or other graphical views included within the MS Word copy?
· If a specific form of delivery is not highlighted in the RFP, deliver as desired by offeror.
Q 33- Given that subcontractors may perform significant portions of the technical scope, will the Government consider allowing relevant past performance information for key subcontractors to be submitted to demonstrate overall team capability?
· Yes. Past performance information from subcontractors can be submitted to demonstrate team capability.
Q 34- Can the Government provide more information on the reserve pool- specifically: (1) approximately how many backup offerors will be entered into the pool and (2) how the Government will evaluate schedule or cost increases during the Final Proposal Request. We cannot provide information on backup offerors at this time, that information is unknown until after official proposals are received.
Q 35- If an offeror is successful in making the competitive range for discussions, but then excluded due to the KO and SSA limitations, when does the Government expect that the debriefing time limits start? The debriefing time limits typically start within 3 days of receiving the notice of exclusion, if a pre-award debriefing is requested.
Further, do the same debriefing time limits occur to unsuccessful offerors that are placed in the reserve pool? They are entitled to a post-award debriefing within 3 days of receiving notice of the award.
Q 36- Is the award letter a notification letter sent to unsuccessful offerors, in addition to the initially successful offeror, as well? A written notification is sent to unsuccessful offerors, but it is not the same as the award letter that will be sent to the successful offeror.
Will the rest of the Reserve Pool know who else is in the pool with them? No Q 37- If this is a small business set aside, why are there compliance clauses and requirements for identifying as a large business?
· The clause is relevant to a large business that intends on partnering with a small business to bid on this contract.
Q 38- What certification level is being addressed in these general requirements?
· The contractor must meet all requirements and standards outlined in Attachment 10 Q 39- How will limited, restricted, government purpose, or specifically negotiated license rights markings that are authorized by the contract clauses be handled? Solicitation Clause 252.227-7015 has form/fit/function data or operation/maintenance/training data normally given to the public being required; but the CDRLs and other deliverables ask for further technical data beyond these where the Government would normally have unlimited rights.
· The USG will conform to the distribution rights outlined on deliverables.
