MANAGEMENT PHILOSOPHY AND POLICY

1.1. Introduction. This instruction prescribes basic aircraft and equipment maintenance management policy implementation and procedures used throughout the USAF to perform

Mission Generation (MG) functions.

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

Organization, or as authorized by 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. The term “Lead Command” is used to describe the technical advocacy and product support provided to individual weapon systems across the using

MAJCOMs as described in 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 shall be maintained to ensure effective and timely response to peacetime operations, mobilizations, national defense contingencies and other emergencies.

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

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

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

1.3.1.3. Depot: repair materiel coded for organizational, intermediate and depot;

overhaul; rebuild; modify and manufacture.

1.3.2. Organizational and intermediate-level maintenance is organized into two mutally supporting 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 providing maintenance required to fulfill operational needs outside the capability and/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 (e.g. supply counter turn-in) or changing an end item possession code from an operational activity to a repair network activity (e.g. depot maintenance).1.3.1. Most MGN units possess a complement of equipment and supplies to perform on-equipment and off-equipment maintenance.

1.3.2.1. RN units may reside at bases that perform mission generation. RN requirements and processes are identified in AFI 20-117, Repair Network Integration (RNI) and when published, AFMAN 20-118, Repair Network Integration (RNI) Operations.

1.3.3. Requests for Assistance (RFA). If a maintenance activity requires assistance for evaluation and/or repair beyond unit capability, requests are made IAW AFI 21-103, Equipment Inventory, Status And Utilization Reporting; TO 00-25-107, Maintenance

AFI21-101 21 MAY 2015 11

Assistance; and TO 00-20-14, AF Metrology and Calibration Program, or automated process as approved by the Mission Design Series (MDS) Program Manager (PM) (e.g., C-130

AIRCATS, F-16 TAR). All requests for assistance must be coordinated through the originating MAJCOM and Lead Command as applicable. (T-2).

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/Missile) to effectively and efficiently support mission generation. Maintainers who attend the USAF Advanced Maintenance and Munitions

Operations School (AMMOS) are trained in advanced operational, expeditionary and tactical maintenance management concepts stemming from the alumni’s development and formalization of TTPs. MXG/CC’s should identify their AMMOS graduates and utilize them as advisors and instructors to enhance mission capability. TTP 3-3, Aircraft Maintenance, can be found at:

https://intelshare.intelink.gov/sites/561jts/3-3/default.aspx. For additional information on

AMMOS and TTP development see AFI 21-111, Advanced Maintenance and Munitions

Education Program.

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 and 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. 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.

1.6. 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.

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

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

https://intelshare.intelink.gov/sites/561jts/3-3/default.aspx

12 AFI21-101 21 MAY 2015

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 Technical Orders (TO) and TO Supplements. Use of the 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. (T-1). All personnel will enforce compliance with technical data. (T-1).

1.7. Communications Security (COMSEC)/Controlled Cryptographic Item (CCI)

Accountability. The Air Force COMSEC/Central CCI Authority is the Cryptologic and Cyber

Systems Division, Joint Base San Antonio-Lackland, Texas.

1.7.1. COMSEC/CCI accountability will be accomplished IAW AFMAN 33-283, Communications Security (COMSEC) Operations and AFI 23-101, Air Force Materiel

Management. (T-1). Questions concerning COMSEC/CCI accountability can be directed to the Cryptologic and Cyber Systems Division’s COMSEC Policy Office (AFLCMC/HNCLS) at DSN 969-3886.

1.8. Environmental Compliance. It is the responsibility of all maintenance personnel to comply with all written guidance to ensure compliance with hazardous material, hazardous waste management and air emissions record keeping as required for environmental compliance IAW

AFI 90- 803, Environmental, Safety, and Occupational Health Compliance Assessment and

Management Program, installation ESOHMS/EMS policy/guidance and applicable environmental requirements and guidance. (T-0).

1.9. Publications. Units may tailor procedures to the unique aspects of their own maintenance operation and publish directives, instructions, supplements, addendums, and, for functional areas, Operating Instructions (OI) IAW AFI 33-360.

1.9.1. Develop, control, and maintain functional checklists, at a minimum, each functional checklist is titled and dated. Functional checklists are not 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.

1.10. Maintenance Training. Maintenance training provides initial, recurring and advanced proficiency, qualification, or certification skills needed by a technician to perform duties in their primary AF Specialty Code (AFSC)/Civilian Job Series. Maintenance training includes combat and sortie generation skills not normally integrated into peacetime operations (e.g., 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 DODD 5000.01. Refer to AFI 63-131, Modification Management, for modification management procedures.

1.11.1. Modifications to Munitions. All proposed modifications to aircraft-carried munitions include SEEK EAGLE certification IAW AFI 63-104, The SEEK EAGLE Program. All

AFI21-101 21 MAY 2015 13

modifications to AF nuclear munitions or their associated support/training equipment are nuclear certified IAW AFI 91-103, Air Force Nuclear Safety Design Certification Program and AFI 63-125, Nuclear Certification Program. All modifications to AF conventional munitions or their associated support/training equipment are certified IAW AFI 91-205, Non-

Nuclear Munitions Safety Board.

1.12. Maintenance Information Systems (MIS). MIS refers to automated maintenance information systems that support and enable maintenance business processes. MIS is used to document maintenance actions and track fleet health. The information entered into the MIS is accomplished IAW TO 00-20-2, Maintenance Data Documentation and match 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/USERIDs of individuals accomplishing the actual work are entered into the MIS. Red Ball maintenance is documented

IAW Chapter 11 of this instruction.

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

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 help when needed, and using 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/crew leaders become task-focused, junior personnel are often better able to assess the danger; however, deferring to the experience and judgment of the crew leader, they may choose to remain silent, missing an opportunity to break the mishap sequence chain.

Maintenance commanders and supervisors are responsible to foster 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 AFPAM 90-803, Risk Management (RM) Guidelines and Tools for additional information.

1.13.2. Visitors. Units 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 their assigned official duties. (T-1). Visitors will not be allowed in the flightline area if munitions operations are present IAW AFMAN 91-201, Explosive Safety Standards. (T-1).

1.14. Duty Shifts and Rest Periods. Maintenance personnel duty hours are aligned to provide optimal mission support.

1.14.1. Supervision at all levels will be equitably distributed to cover all duty periods. (T-2).

1.14.2. Personnel will not be scheduled for more than 12…
