AF Form 1067 Modification Proposal Guide & Download 2026 – If you serve in the US Air Force, US Space Force, or support DAF programs as a contractor, you know how critical it is to keep fielded systems, aircraft, equipment, and software mission-ready. The AF Form 1067 (Modification Proposal) is the official document that initiates, tracks, reviews, and approves changes to in-service assets. Whether you need a quick temporary fix for an urgent operational need or a permanent upgrade to extend service life, this form ensures every modification follows disciplined configuration control, funding, and safety protocols.
This comprehensive guide explains exactly what AF Form 1067 is, when and how to use it, the step-by-step completion process, approval workflow, and where to download the latest official PDF. All information is drawn directly from current Department of the Air Force guidance (DAFI 63-101/20-101, dated 16 February 2024, with subsequent guidance memoranda) and supporting capability development resources.
What Is AF Form 1067?
AF Form 1067, titled Modification Proposal, is the standardized DAF form used to document proposals for modifications to fielded weapons systems, subsystems, end-items, software, or activities that are already in Air Force or Space Force inventory (accepted via DD Form 250 or full software deployment).
It serves as the single source for:
- Capturing the operational need or deficiency
- Describing the proposed change and expected results
- Identifying affected configured items (Mission Design Series/MDS, National Stock Number/NSN, etc.)
- Documenting technical, logistics, cost, schedule, and risk impacts
- Routing the proposal through validation, technical assessment, and formal approval
The form maintains configuration control even when the change builds on a previously approved capability requirements document. It triggers actions such as engineering change proposals (ECPs), Time Compliance Technical Orders (TCTOs), and updates to the Life Cycle Sustainment Plan (LCSP).
Important note: Routine maintenance, interchangeable parts without form/fit/function changes, depot-level repairs, or facility modifications are not processed via AF Form 1067.
Purpose of the AF Form 1067 Modification Proposal
The primary purpose is to:
- Formally request approval for temporary or permanent modifications
- Ensure proposed changes enhance operational effectiveness, suitability, survivability, safety, or reduce ownership costs
- Provide a clear technical requirements baseline for the Program Manager (PM)
- Track the proposal through funding, implementation, and close-out
- Support integration into the Acquisition Master List (AML) when investment funding is required
Modifications must be tied to an operational mission requirement. The form forces early identification of risks, costs (documented in Blocks 25 and 30), and schedule impacts so leadership can make informed decisions.
Types of Modifications on AF Form 1067
DAFI 63-101/20-101 (Chapter 9) defines three main categories:
- Permanent Modifications — Long-term baseline changes that alter form, fit, function, or interface. These are installed fleet-wide (or on a validated subset) and may require capability requirements documentation if they exceed cost thresholds.
- Temporary Type-1 (T-1) — Operational modifications for short-term mission needs (usually ≤1 year). Must include removal or conversion plan to permanent status.
- Temporary Type-2 (T-2) — Test and evaluation modifications to support developmental testing. Removed after testing unless upgraded.
Safety modifications receive priority funding and implementation.
Who Uses AF Form 1067?
- Initiators: Using commands, operators, maintainers, or any stakeholder who identifies a need
- Lead/Using Commands: Validate and prioritize proposals
- Program Managers (PMs) and Product Group Managers: Perform technical, cost, and risk assessments
- Program Executive Officers (PEOs) and Milestone Decision Authorities (MDAs): Provide final approvals based on cost/schedule thresholds
- Single Managers: Oversee portfolio-level modifications
Contractors supporting DAF programs often assist in preparing supporting data.
Step-by-Step: How to Complete AF Form 1067
Detailed block-by-block instructions are in DAFI 63-101/20-101, Attachment 2. The form is divided into Parts I–V with specific responsibilities:
- Part I (Initiator / Request for Action): Proposal title, description of the need/deficiency, expected results, affected item/system details, modification type (P, T-1, or T-2), impacts, constraints, and assumptions. Attach supporting data (e.g., deficiency reports, SEEK EAGLE requests).
- Part II (Using/Lead Command Validation): Certification of operational need, prioritization, and funding intent.
- Part III (PM Technical Assessment): Systems engineering analysis, logistics impacts, cost estimates (Blocks 25/30), schedule, risk, and recommendation.
- Part IV (PM Accomplishment): Execution planning once approved.
- Part V (Final Approvals / Close-out): Signatures from required authorities; later used for fielding confirmation and removal of temporary mods.
Pro tips for filling it out:
- Be specific and data-driven in the “Purpose” and “Impact” sections.
- Clearly state the number of units affected and duration (especially for T-1 mods).
- Include cost breakdowns — total funding in Blocks 25 and 30 determines approval level.
- Attach all supporting documentation early to avoid delays.
Always consult the latest DAFI 63-101/20-101 and your local MAJCOM or program office procedures.
The AF Form 1067 Approval and Implementation Process
- Initiation → Submitter completes Part I and routes to using/lead command.
- Validation → Lead command reviews, certifies, and prioritizes (Part II).
- PM Review → Program Manager assesses technical feasibility, costs, risks, and completes Part III/IV.
- Approval → Routed per cost thresholds (e.g., Configuration Steering Board for major impacts; PEO/MDA for larger programs).
- Implementation → Approved proposals lead to ECP development, TCTO issuance, fielding, and configuration updates.
- Close-out → Temporary mods are removed or converted; permanent changes update baselines and are reported via PMRT/PDAA.
For Urgent Capability Acquisitions (UCA), a streamlined AF Form 1067 or Decision Memorandum may be used.

Best Practices & Common Pitfalls to Avoid
- Submit early with complete supporting data to prevent “return for more information.”
- Coordinate with your PM and Chief Engineer before routing.
- Clearly justify why a temporary modification is required (especially T-1 >1 year).
- Document removal plans for temporary mods.
- Update the LCSP and report via the Program Management Review Tool (PMRT) after approval.
Poorly prepared 1067s delay fielding and can impact readiness — use the DAFI Attachment 2 checklist.
Frequently Asked Questions (FAQs)
Q: Is AF Form 1067 only for aircraft?
A: No — it applies to any DAF-managed fielded system, subsystem, software, or equipment.
Q: What is the difference between AF Form 1067 and an ECP?
A: The 1067 initiates the user requirement and approval; the ECP provides the detailed engineering solution.
Q: Where do I find the exact block instructions?
A: DAFI 63-101/20-101, Chapter 9 and Attachment 2 (available on e-Publishing).
Q: Can contractors submit AF Form 1067?
A: Usually through the using command or PM office; contractors provide supporting technical data.
