Chapter 1

MANAGEMENT OVERVIEW, SUPPORTING CONCEPTS AND REQUIREMENTS.

1.1. Introduction. This instruction prescribes basic aircraft and equipment maintenance management policy implementation and procedures used throughout the United States Air Force

(USAF) to perform Mission Generation (MG) functions.

1.1.1. (Added-AFRC) HQ AFRC/A4M org box email addresses are as follows:

1.1.1.1. (Added-AFRC) HQ AFRC/A4M (hqafrc.a4m.maintenance@us.af.mil).

1.1.1.2. (Added-AFRC) HQ AFRC/A4MA

(hqafrc.a4ma.aircraftmaintenance@us.af.mil).

1.1.1.3. (Added-AFRC) HQ AFRC/A4MM

(hqafrc.a4mm.MaintenanceManagement@us.af.mil).

1.1.1.4. (Added-AFRC) HQ AFRC/A4MS

(hqafrc.a4ms.aircraftmaintenancesupport@us.af.mil).

1.1.1.5. (Added-AFRC) HQ AFRC/A4MM AVDO (A4.MM.AVDO@us.af.mil)

1.2. Organization. AF organizations are structured according to AFI 38-101, Air Force

Organization, or as authorized by the Director of Manpower, Organization & Resources

(AF/A1M). Contracted maintenance functions are not required to organize IAW AFI 38-101 but will implement the organization as outlined in their proposal as accepted by the government. For the definition of “Lead Command” see AFPD 10-9, Lead Command Designation and

Responsibilities for Weapon Systems.

1.3. Maintenance Concept. Per AFPD 21-1, organizational, intermediate, and depot maintenance capabilities for operational readiness will be maintained to ensure effective and timely response to peacetime operations, mobilizations, national defense contingencies, and other emergencies. Note: Guidance for the use of Additive Manufacturing to build replacement parts is prescribed in AFI 63-101/20-101, Integrated Life Cycle Management.

1.3.1. As a minimum each capability will be able to:

1.3.1.1. Organizational: launch and recover sorties, maintain, and repair materiel coded for organizational level repair.

1.3.1.2. Intermediate: repair materiel coded for organizational and intermediate level repair in back shops, centralized repair facilities, or both.

1.3.1.3. Depot-level Maintenance: Provides the capability to maintain materiel coded for organizational, intermediate and depot levels of maintenance. Includes maintenance requiring the overhaul, upgrading, or rebuilding of parts, assemblies, or subassemblies, and the testing and reclamation of equipment as necessary.

1.3.2. Organizational and intermediate-level maintenance is organized into two mutually exclusive networks, the Mission Generation Network (MGN) and the Repair Network (RN).

The MGN is optimized for mission generation at the wing level and consists of authorized “on-equipment” and “off-equipment” maintenance capabilities required to launch, recover, configure, inspect, and repair AF systems and equipment. The RN supports the MGN by mailto:hqafrc.a4m.maintenance@us.af.mil mailto:hqafrc.a4ma.aircraftmaintenance@us.af.mil mailto:hqafrc.a4mm.MaintenanceManagement@us.af.mil mailto:hqafrc.a4ms.aircraftmaintenancesupport@us.af.mil mailto:A4.MM.AVDO@us.af.mil

14 DAFI21-101 30 OCTOBER 2024

providing the maintenance required to fulfill operational needs outside the capability or capacity of MGN activities. The interface between the two networks takes place when the

MGN activity relinquishes control of reparable assets to the RN activity (such as, supply counter turn-in) or changes an end item Purpose Identifier Code (PIC) from an operational activity to a repair network activity (such as, depot maintenance).

1.3.2.1. Most MGN units possess a complement of equipment and supplies necessary to perform on-equipment and off-equipment maintenance.

1.3.2.2. RN units may reside at bases that perform mission generation. RN requirements and processes are identified in DAFI 20-117, Repair Network Management.

1.3.3. MAJCOMs assigned combat coded fighter aircraft will coordinate with Mission Design

Series (MDS) lead and using commands and the MAJCOM Operations Directorate

(MAJCOM/A3) to develop and document standardized MDS and Primary Aerospace Vehicle

(Aircraft) Authorized (PAA) specific utilization rate standards in their supplements to this instruction. At a minimum the rates will:

1.3.3.1. Consider aggregated and analyzed unit generation capability data to identify and document standard MDS turn patterns by PAA in their supplements to Chapter 14.

1.3.3.2. Account for standard avionics and weapons training configurations.

1.3.3.3. Account for standard Technical Order (TO) driven turn time inspections and

Average Sortie Duration.

1.3.3.4. Include a process for supporting units in assessing shortfalls and developing action plans.

1.3.4. Requests for Assistance. If a maintenance activity requires assistance for evaluation, repair, or both, beyond unit capability, requests are made IAW DAFI 21-103, Equipment

Inventory, Status and Utilization Reporting; TO 00-25-107, Maintenance Assistance; and TO

00-20-14, AF Metrology and Calibration Program, or automated process as approved by the

MDS Program Manager (PM) (for example, C-130 Automated Inspection, Repair, Corrosion and Aircraft Tracking (AIRCAT), F-16 Technical Assistance Request). All requests for assistance must be coordinated through the originating MAJCOM and Lead Command as applicable.

1.3.4. (AFRC) Submit requests to HQ AFRC/A4MA and provide copy to applicable

NAF/A4M. HQ AFRC/A4MA is the first stage of coordination for any TO 00-25-107 request which include AFRC funding, Dash 6 extensions, Dash 6 waivers, Depot Field Team, or any agency requiring AFRC concurrence/approval.

1.4. Aircraft Maintenance Tactics, Techniques and Procedures (TTP). TTPs are developed from lessons learned and best practices that provide valuable reference documents to improve maintenance processes and procedures. Maintenance leaders should utilize the maintenance fundamentals TTP volumes (Aircraft, Munitions and Missile) to support mission generation effectively and efficiently. Maintainers who attend the USAF Advanced Maintenance and

Munitions Operations School are trained in advanced operational, expeditionary, and tactical maintenance management concepts stemming from the alumni’s development and formalization of TTPs. Maintenance Group Commanders (MXG/CC) should identify their Advanced

Maintenance and Munitions Operations School graduates and utilize them as advisors and

DAFI21-101 30 OCTOBER 2024 15

instructors to enhance mission capability. AFTTP 3-4.21V1, Aircraft Maintenance, can be found at: https://www.e-publishing.af.mil or https://usaf.dps.mil/teams/TTP/SitePages/Home.aspx.

For additional information on Advanced Maintenance and Munitions Operations School and TTP development see Air Force Manual (AFMAN) 21-111, Advanced Maintenance and Munitions

Operations School.

1.5. Aircraft and Equipment Readiness. Aircraft and equipment readiness is the maintenance mission. The maintenance function ensures assigned aircraft and equipment are safe, serviceable, and properly configured to meet mission needs. Maintenance actions include, but are not limited to, inspection, repair, overhaul, modification, preservation, refurbishment, troubleshooting, testing, analyzing condition, performance, and maintenance documentation. All levels of supervision need to place emphasis on safety, quality, and timeliness in the performance of maintenance. The concept of quality maintenance must be fostered by each supervisor and technician to ensure the integrity and skill of each maintainer is not degraded. To the greatest extent possible, maintenance is accomplished on a preplanned scheduled basis. Planning provides the most effective and efficient use of people, facilities, and equipment; reduces unscheduled maintenance; and allows for progressive actions toward maintaining and returning aircraft and equipment to safe operating condition. Exploiting repair network capability and maintaining visibility of repair cycle assets throughout the maintenance cycle are also critical elements of the equipment maintenance program.

1.5.1. The Air Force has established strategic-level aviation support equipment management within the 440 SCOS: Aviation Support Equipment Management Flight (ASEMF). The

ASEMF has the responsibility to align with the integration of Aviation Support Equipment

Maintenance Information System (AvSE MIS), also referred to as Defense Property

Accountability System (DPAS) Maintenance and Utilization (M&U) Module capabilities. As

AvSE MIS (DPAS M&U) comes online and units migrate assets into the new system, ASEMF will start to stand up and data mine available metrics on AvSE from AvSE MIS. These efforts combined (AvSE MIS and ASEMF) give the AF the greatest return to increasing one element of overall readiness in support of the National Defense Strategy (NDS).

1.5.2. Preventive Maintenance. AF units implement and manage the tasks specified in the scheduled recurring maintenance program for their assigned aircraft and associated support equipment (SE). Preventive maintenance is achieved through the inspection requirement concepts described in TO 00-20-1, Aerospace Equipment Maintenance Inspection, Documentation, Policy, and Procedures, and applicable weapon system -6 TO.

1.5.3. MAJCOMs that conduct Mission Generation Assessments or similar weapon system logistic evaluations in order to validate unit readiness will:

1.5.3.1. Provide units a standardized assessment report containing, at a minimum, positive, negative, and areas for improvement feedback to facilitate cross tell to like units.

1.5.3.1.1. Analyze unit generation processes to capture and communicate best practices.

1.5.3.1.2. Analyze unit generation performance to identify and communicate noteworthy trends.

1.5.3.2. Directorates of Logistics, Engineering & Force Protection (MAJCOMs A4s) will semi-annually report their top three trends and causal factors to the Logistics Board to https://www.e-publishing.af.mil/ https://usaf.dps.mil/teams/TTP/SitePages/Home.aspx

facilitate debate to identify and mitigate potential limiting factors. Submit MAJCOM top three trends to the AF/A4LX workflow no later than 30 days prior to each Logistics Board meeting for consolidation at: AF.A4LX.Workflow@us.af.mil.

1.6. Maintenance Discipline. It is the responsibility of all maintenance personnel to comply with all written guidance to ensure required repairs, inspections, and documentation are completed in a compliant, safe, timely, and effective manner. Supervisors are responsible for enforcing and establishing a climate that promotes maintenance and supply discipline. Unless expressly stated otherwise in a particular instruction, waiver, or deviation in this DAFI granted by the appropriate authority, all Airmen must follow AFIs. AFIs do not provide optional guidance, and failure to comply with DAFIs can result in disciplinary action as described in AFI 1-1, Air Force Standards.

Civilian personnel who violate punitive publications may also be subject to disciplinary action.

See DAFMAN 90-161 for more detailed information on the use of punitive language in publications.

1.6.1. Compliance Terminology. For the purposes of this instruction, the following definitions apply:

1.6.1.1. Must, Will - Indicates mandatory requirements. Note: “Will” is also used to express a declaration of purpose for a future event.

1.6.1.2. Should - Indicates a preferred method of accomplishment.

1.6.1.3. May - Indicates an acceptable or suggested means of accomplishment.

1.6.2. Use of TOs and TO Supplements. All personnel will enforce compliance with technical data. (T-2) Use of prescribed technical data to maintain aircraft and equipment is mandatory and will be conducted and managed IAW TO 00-5-1, Air Force Technical Order System.

1.6.3. AFTO Form 492, Maintenance Warning Tag. The Air Force Technical Order (AFTO)

Form 492, Maintenance Warning Tag, is used as prescribed in technical data, local procedures, or both, to flag a condition that could cause damage or injury if ignored. Refer to TO 00-20-1 for additional guidance. Note: The AFTO Form 492 is replacing the AF Form 1492, Warning

Tag referenced in DAFMAN 91-203, Air Force Occupational Safety, Fire, and Health

Standards. Use of the AF Form 1492 is authorized until supplies are exhausted.

1.9.1. Develop, control, and maintain functional and emergency action checklists. At a minimum, each checklist is titled, dated, and coordinated with the wing safety office.

Functional checklists are not to be used in place of or to circumvent technical data for operation, servicing, inspection or maintenance of aircraft, aircraft systems, munitions, and all other equipment supporting aircraft and munitions maintenance.

1.9.2. Methods and Procedures Technical Orders (MPTOs): Due to the close relationship between MPTOs and this DAFI, all changes and revisions to the MPTOs cited in Attachment

1, References of this DAFI will be routed from Air Force Material Command (AFMC) to

AF/A4LM for content review for conflicts and policy gaps identification and mitigation prior to submission for publication.

1.10. Maintenance Training. Maintenance training provides initial, recurring, and advanced proficiency, qualification, or certification skills needed by a technician to perform assigned duties.

Maintenance training includes combat and sortie generation skills not normally integrated into peacetime operations (such as, Multi-Capable Airmen, munitions handling, and external fuel tank build-up, hot refueling). Maintenance training carries an equal priority with the operational training mission. For maintenance training policy and guidance, refer to AFI 36-2650, Maintenance Training and MAJCOM supplements.

1.11. Modification Management. A modification proposal is a recommendation to change the operation, use, or appearance of AF equipment. Modifications (temporary, permanent, or safety) to AF aircraft or equipment are expressly prohibited without PM approval. Note: PM is used in this publication as defined in AFPD 63-1, Integrated Life Cycle Management. Refer to AFI 63-

Command Designation and Responsibility, System Program Office, and/or the Integrated

Combat Command for OSS&E compliance.

1.12. Maintenance Information System (MIS). MIS refers to automated maintenance information systems that support and enable maintenance business processes. The MIS is used to document maintenance actions and track fleet health. The information entered into the MIS is accomplished IAW TO 00-20-2 and matches the content of the aircraft forms. MIS data entries do not have to be accomplished by the same individual who documented the aircraft forms, but employee numbers, man numbers, and User IDs of individuals accomplishing the actual work are entered into the MIS. Red Ball maintenance is documented IAW Chapter 11. Data integrity is the responsibility of every member of the unit. All personnel are responsible for ensuring accuracy and completeness.

1.12.1. Units use the approved MIS for their assigned weapon system.

1.12.1. (AFRC) Units will ensure aviation support equipment (AvSE) is accurately profiled

IAW the DPAS M&U Interim Guidance.

1.12.2. Serial numbers will be documented in the MIS for all serially controlled and tracked assemblies that are identified by an asterisk in the Work Unit Code (WUC) or Logistics Control

Number (LCN) manual IAW TO 00-20-2.

1.13. General Safety Guidance. Maintenance personnel are exposed to a large variety of hazardous situations, machinery, equipment, and chemicals. Most hazardous situations can be avoided by following approved procedures, asking for assistance when needed, and using all required personal protective equipment (PPE).

1.13.1. Safety “Knock It Off” and Risk Management. Due to the inherent danger to life, limb, and property associated with maintenance operations, personnel are empowered to terminate an operation or situation which they perceive is unsafe or too dangerous. When supervisors or crew leaders become task-focused, junior personnel are often better able to assess the danger;

however, deferring to the experience and judgment of the supervisor or crew leader, they may choose to remain silent, missing an opportunity to break the mishap sequence chain.

Maintenance commanders and supervisors are responsible for fostering a culture in their units so that a simple, but recognizable “audible” from anyone can prevent a potential mishap. Note:

See AFI 90-802, Risk Management, and DAFPAM 90-803, Risk Management (RM) Guidelines and Tools for additional information.

1.13.2. Visitors. Unit Commanders will not permit visitors to operate any AF equipment unless they are qualified to operate such equipment and are doing so in the performance of

DAFI21-101 30 OCTOBER 2024 21

their assigned official duties. (T-2) Visitors will not be allowed in the flightline area if munitions operations are present IAW DESR6055.09_AFMAN 91-201, Explosive Safety

Standards.

1.14. Duty Shifts and Rest Periods. MXG/CC or equivalent will establish minimum requirements that ensure units maintain an equitable distribution of supervision (Officer and Senior

Non-Commissioned Officer (SNCO)) across all on-duty shifts in their supplement to this DAFI.

(T-3)

1.14.1. During normal operations, maintenance personnel are scheduled for duty based on a

40-hour work week. Maintenance personnel duty hours are aligned to provide optimal mission support.

1.14.2. Personnel will not be scheduled for more than 12 hours of continuous duty time. (T-3)

Duty time begins when personnel report for duty and ends when their supervisor releases them.

Time spent in exercise or contingency deployment processing lines and in-transit counts toward the total duty day. SQ/CCs are the final approval authority for duty time extensions exceeding the 12-hour limit up to a maximum of 16 hours. (T-3) Note: Aircraft or detachment commanders assume this responsibility in Temporary Duty (TDY) or travel status.

1.14.3. Commanders and supervisors will provide a rest period after each shift. (T-3) A rest period is a block of time that gives a person the opportunity for 8 hours of uninterrupted sleep in a 24-hour period.

1.14.4. When handling, loading, or performing maintenance on nuclear weapons, conventional munitions, or egress explosives, personnel will follow requirements IAW

AFMAN 21-200.

1.14.5. In alert force or standby duty situations where facilities are available for resting, established norms may be exceeded. Adjust rest periods to allow for 8 hours of uninterrupted sleep.

1.14.6. Commanders and supervisors will ensure individuals are afforded adequate duty rest periods and breaks to prevent fatigue or thermal injury. Stop anyone if fatigue may jeopardize safety. In all cases, aircraft commanders or supervisors ensure aircraft maintenance personnel are not required to perform duty when they have reached the point of physical or mental fatigue rendering them incapable of performing their assigned duties safely and reliably.

1.14.7. MAJCOM Commanders will assume the risk for any Flying Crew Chief (FCC) deviations from normal duty shifts, rest periods, and exceedance of the 16-hour maximum duty day. MAJCOM Commanders will publish risk-mitigation procedures in order to meet critical mission requirements.

1.14.7. (AFRC) The aircraft commander (AC) must conduct a risk assessment prior to the

Flying Crew Chief (FCC)/Mission Essential Personnel (MEP)(s) exceeding the 16-hour duty day while the FCC/MEP is part of the aircrew complement. (T-2) The AC has authority over the FCC/MEP’s work/rest cycles when the mission/flight is designated Reserve Airlift Support

(RAS) or an Executive Airlift (EA) Mission. (T-2) The AC must complete Attachment 10

Extended Workday Risk Assessment prior to FCC/MEP(s) exceeding the 16-hour workday

(T-2), and document assessment for MXG/CC review. (T-3) Note: Refer to AFRCI 11-201, AFRC Flying Operations for more on RAS and crew rest reporting procedures and refer to

22 DAFI21-101 30 OCTOBER 2024

Missions and crew rest reporting procedures. Refer to Ch.11.20 of this instruction for more on

FCC guidance.

1.15. Communications. Commanders will develop communication plans according to AF mission requirements. See Chapter 11 for detailed communication requirements.

1.15.1. Effective maintenance accomplishment requires the ability to communicate across all facets of the maintenance operation efficiently and effectively. Communication technology

(government issued Portable Electronic Devices (PED), Portable Maintenance Aid (PMA), radios, cell phones, computers, wireless internet) must be available to expedite personnel, equipment, material, and maintenance data throughout the maintenance complex. (T-2)

1.15.2. MAJCOMs will publish guidance for the use and control of personal communications devices (personal cell phones, tablets, and computers) on the flightline, in munitions areas, hangars, and other industrial work areas as required to mitigate cyber risk and ensure compliance with cyber and communication AFI requirements relevant to their operational environments.

1.15.2. (AFRC) Personal cell phones and other electronic devices possessed on the flight line or in maintenance work areas will only…
