AF Form 3624 Equipment Outage Log – Download & Guide

AF Form 3624 Equipment Outage Log – Download & Guide – The DAF Form 3624, officially titled EQUIPMENT OUTAGE LOG, is a critical document used by Department of the Air Force (DAF) airfield operations, air traffic control (ATC), and related units to track equipment downtime. Accurate logging ensures safety, regulatory compliance, and operational continuity at Air Force and Space Force installations.

This article explains what AF Form 3624 is, its purpose, how to complete it, who uses it, and where to download the latest version.

What Is AF Form 3624?

DAF Form 3624 (previously often referred to as AF IMT Form 3624) is the official Equipment Outage Log prescribed by DAFMAN 13-204 Volume 3 (Air Traffic Control Procedures). The current revision is dated 26 April 2024 (20240426), and previous editions are obsolete.

The form provides a standardized way to record when critical equipment—such as navigational aids (NAVAIDs), radar, weather systems, communications gear, or other airfield systems—goes out of service and when it returns.

Purpose of the Equipment Outage Log

The primary goal of AF Form 3624 is to:

  • Document equipment outages for safety and accountability.
  • Support trend analysis and maintenance tracking.
  • Ensure timely notification and resolution of issues affecting flight operations.
  • Help meet inspection, audit, and reporting requirements under Air Force airfield operations instructions.

In air traffic control towers and airfield operations facilities (AOF), controllers and supervisors log outages on this form. Related publications, such as local wing instructions (e.g., 12 FTWI13-204 or Maxwell AFB instructions), explicitly require using AF Form 3624 to document equipment and NAVAID outages.

Proper use contributes to overall airfield safety by maintaining visibility of system reliability.

Who Uses DAF Form 3624?

  • Air Traffic Control (ATC) personnel
  • Airfield Operations Flight (AOF) staff
  • Weather personnel (for certain systems like RAWS – Remote Automated Weather Systems)
  • Maintenance and communications-electronics (C-E) teams
  • Supervisors and facility managers who review daily logs

It is commonly used alongside other standard forms, including:

  • AF Form 3616 – Daily Record of Facility Operation
  • AF Form 3626 – Position Log
  • AF Form 3623 – Daily Traffic Count

All these forms are typically initiated at the beginning of the mid-shift.

Key Fields on AF Form 3624

The form is straightforward and includes the following main blocks (based on the official PDF layout):

  • Work Order Number — Reference to the associated maintenance or repair ticket.
  • Equipment — Specific name or identifier of the equipment experiencing the outage (e.g., ASR-11 Radar, ILS Glide Slope, specific NAVAID).
  • Date/Time Out — Exact date and time the equipment went offline or was declared out of service.
  • Inclusive Dates — Period covered by the outage (useful for multi-day events).
  • Date/Time In — Date and time the equipment was restored to service.
  • Remarks — Detailed notes, cause of outage, actions taken, impact on operations, or additional context.
  • ATC/WLC (or similar) — Initials or codes for the controller or watch supervisor who logged the entry.

Clear, accurate, and timely entries are essential. Remarks should be factual and sufficient for someone reviewing the log later to understand the event.

How to Fill Out AF Form 3624 (Step-by-Step Best Practices)?

  1. Initiate the log at the start of the shift or as soon as an outage is identified.
  2. Enter the Work Order Number if maintenance has been called.
  3. Clearly identify the Equipment affected.
  4. Record the precise Date/Time Out using Zulu (Z) or local time as required by your facility.
  5. Add detailed Remarks (what happened, who was notified, operational impact).
  6. When the equipment returns, promptly enter the Date/Time In and close out the entry with any final remarks or initials.
  7. Supervisors review and initial logs as required by local instructions.

Always follow your specific DAFMAN 13-204 guidance and unit-level operating instructions. Some bases require logging all NAVAID outages on both AF Form 3624 and AF Form 3616.

Why Accurate Outage Logging Matters?

  • Safety: Untracked outages can lead to increased risk in the National Airspace System.
  • Compliance: Air Force instructions mandate documentation for audits and inspections.
  • Maintenance Efficiency: Detailed logs help identify recurring issues and support faster repairs.
  • Accountability: Provides a clear historical record for investigations or trend analysis.

Failure to properly document can complicate reporting and affect readiness evaluations.
