EXECUTIVE SUMMARY
This Navy Training System Plan addresses manpower, personnel, and training requirements associated with the Nondestructive Inspection (NDI) Program. NDI is the practice of evaluating a part or sample of material without impairing its future usefulness. Methods of inspection include, but are not limited to, visual, optical, liquid penetrant, magnetic particle, eddy current, ultrasonic, and radiographic. Success in their use depends heavily upon intelligent application and discriminating interpretation of results. The NDI Program equipment is in the Production, Deployment, and Operational Support Phase of the Weapon System Acquisition Process.
The NDI Program is performed per the Naval Aviation Maintenance Program (NAMP), Office of the Chief of Naval Operations Instruction (OPNAVINST) 4790.2G and the NDI Methods Manual (NA 01-1A-16) at the organizational, intermediate, and depot levels of maintenance. There are three basic categories of NDI personnel: NDI Operator, NDI Technician, and NDI Specialist. NDI Operators are Navy and Marine Corps maintenance personnel or civil service personnel who have successfully completed required training and are certified to perform limited NDI tasks. NDI Technicians are Navy and Marine Corps personnel, normally attached to Intermediate Maintenance Activities, assigned Navy Enlisted Classification 7225 or Military Occupational Specialty 6044, qualified and certified to perform liquid penetrant, magnetic particle, eddy current, ultrasonic, and radiographic methods of NDI. NDI Specialists are military or civil service personnel, designated by the applicable Aircraft Controlling Custodian (ACC)/Type Commander (TYCOM), authorized to provide refresher and specialized training and triennial recertification of NDI Technicians. Specialists are also authorized to train and certify NDI Operators.
The Aircraft Nondestructive Inspection Technician Class C2 course (Course Identification Number (CIN) C-603-3191), located at Naval Aviation Technical Training Center Pensacola, Florida, provides NDI Technician training for career designated Navy Aviation Structural Mechanics (Structures) and Marine Corps (Structures Mechanics) personnel in paygrades E-4 and above, and civil service personnel. NDI Operator training in liquid penetrant, magnetic particle, and eddy current methods, refresher training, and recertification of NDI Technicians is provided by the appropriate Naval Aviation Depots (NAVAVNDEPOT) or ACC/TYCOM designated NDI Specialists. NDI Technicians failing to maintain proficiency for one year or more require update training by NAVAVNDEPOTs or ACC/TYCOM designated NDI Specialists prior to recertification. NDI Technicians failing to maintain proficiency for three years or more are required to attend the Non-Destructive Inspection Technician Recertification course (CIN N-701-0005) provided by NAVAVNDEPOT North Island, California; NAVAVNDEPOT Cherry Point, North Carolina; NAVAVNDEPOT Jacksonville, Florida; or Naval Shipyard Portsmouth, Virginia, prior to recertification.

D. SYSTEM DESCRIPTION
1. Operational Uses. NDI is the practice of evaluating a part or sample of material without impairing its future usefulness. Different components and materials require different NDI methods, and the type of defect or flaw determines the NDI procedure to be used. Some components can be inspected on the aircraft, while others must be removed.
The Navy has long maintained an NDI program to perform on-site, in-service inspections of critical airframe and engine components for service induced damage and defects. NDI equipment is used by Intermediate Maintenance Activities (IMA) ashore and afloat to conduct NDI of aircraft structures, components, engines, and support equipment and is capable of detecting and evaluating defects such as disbonds, cracks, porosity, water pockets, fuel leaks, foreign inclusions, and corrosion. NDI equipment can also be used for sorting and classifying material, measuring thickness of coatings on ferrous and nonferrous metals, gauging thickness of materials to determine the location of defects, and measuring the physical thickness of test objects.
The use of NDI will increase significantly with the fleet introduction of the F/A-18 E/F and V-22 aircraft. This new generation of aircraft uses composite structural materials that require special considerations for maintenance and NDI.
The NDI requirements for in-service aircraft originate in Safety Bulletins or unsatisfactory reports, and are incorporated in existing Maintenance Requirements Cards (MRC). New aircraft weapon systems are supplied with NDI manuals that serve as guidelines for NDI. There are three distinct steps involved in NDI for damage assessment. The first step is to locate the damage. The second step, required to arrive at the method of repair, is to evaluate the defect to determine its type, depth, and size. The third step is to reevaluate after defect removal, as applicable, the area under repair for first layer damage and masked or hidden damage. Post-repair inspection and quality assurance, again utilizing NDI methods, are required to ensure the integrity of the repair.
The NDI methods used to detect service induced damage and defects include the following:
a. Fluorescent Liquid Penetrant. This inspection technique is a method for finding small discontinuities on the surface of solid and essentially nonporous materials. The method uses a chemical that fluoresces under ultraviolet light. Surface cracks, laps, porosity, shrinkage areas, laminations, and similar discontinuities can be detected.
b. Magnetic Particle. This inspection technique is a method of locating discontinuities at or near the surface in ferromagnetic materials. Discontinuities that lie in a direction generally transverse to the direction of the magnetic field will cause a leakage field at and above the surface of the part. The discontinuity is detected by using finely divided ferromagnetic particles applied over the surface. The particles are gathered and held by the leakage field and form an outline of the discontinuity indicating location, size, shape, and extent.
c. Eddy Current. This inspection method is used to detect a wide variety of physical, structural, and metallurgical conditions in ferromagnetic and nonferromagnetic materials. It is also used to inspect fastener holes and aircraft wheels for cracks and corrosion. Eddy current (electromagnetic) variations in the flow of an electric current produce indications of defects as the current passes through the part being tested.
d. Ultrasonic. This inspection method is used to detect and characterize internal flaws, detect surface flaws, define bond characteristics, measure thickness and extent of corrosion, and detect flaws in composite materials. These methods use ultrasonic sound waves passed through the part to produce indications of cracks, laminations, pores, bonding faults, inclusions, or other discontinuities. Pulse-echo methods are those in which a pulsed ultrasonic beam is introducted into the part to be inspected and the signals (echos) returning to the surface of the part are monitored either by the interrogating transducer or a second transducer. Contact methods are those wherein the piezoelectric transducers are normally held in contact with the part surface by hand.
e. Radiography. This inspection method is used to detect internal flaws located well below the surface. Radiography is a technique which involves passing electromagnetic radiation (X-rays) through an object to produce indications on film (e.g., a photograph of the internal characteristics of the part). Defects causing X-ray absorption changes will be identifiable on the X-ray film.
f. Visual or Optical. Visual or optical inspection, except in transparent materials, is used to find flaws evident at the surface. Internal flaws such as delaminations or unbonds are not detectable.
g. Leak Detection. This is the determination of the rate at which a liquid or gas will penetrate from inside a "tight" component or assembly to the outside (or vice versa) as a result of a pressure differential between the two regions. Leak detectors are portable, self-contained, stand-alone instruments, capable of detecting leaks in a system pressurized with helium, hydrogen, or fluorocarbon refrigerants at a specified rate, or through ultrasonic techniques.
h. Hardness Test. Hardness testing equipment is of the static identation type in which a ball, cone, or pyramid is forced into the surface of the metal being tested. The relationship of the area to the depth of indentation is the measure of hardness.
2. Foreign Military Sales. Not Applicable (NA)
E. DEVELOPMENTAL TEST AND OPERATIONAL TEST. Operational Evaluation is not required for NDI equipment. Technical Evaluation (TECHEVAL) on all NDI equipment is conducted by the Naval Air Warfare Center Aircraft Division, Support Equipment and Technical Evaluation Branch, Patuxent River, Maryland.

H. CONCEPTS
1. Operational Concept. NDI on Navy and Marine Corps aircraft structures, systems, components, and support equipment is performed by NDI Operators and Technicians per OPNAVINST 4790.2G and the NDI Methods Manual (NA 01-1A-16). However, the actual repair of NDI detected defects is performed by other maintenance personnel. The IMAs are responsible for the overall readiness and maintenance of the NDI equipment. There are three basic categories of NDI personnel: NDI Operators, NDI Technicians, and NDI Specialists, as defined below.
a. NDI Operators. NDI Operators are Navy and Marine Corps aviation personnel and civil service personnel who successfully complete required training and are certified to perform limited NDI tasks. Organizational level NDI Operators normally perform only Technical Directives and liquid penetrant NDI methods. Organizational level NDI Operators may also perform specific magnetic particle and eddy current method inspection when specifically authorized by the cognizant Aircraft Controlling Custodian (ACC)/Type Commander (TYCOM). Authorization is normally granted only when organizational level activities must operate with no IMA support. Naval Aviation Depots (NAVAVNDEPOT) or ACC/TYCOM designated NDI Specialists normally provide NDI method training for NDI Operators. Recertification of NDI Operators is required annually.
b. NDI Technician. NDI Technicians are military and civilian personnel who successfully complete Course Identification Number (CIN) C-603-3191, Aircraft Nondestructive Inspection Technician Class C2. Career designated Navy Aviation Structural Mechanic (Structures) (AMS), Marine Corps Structures Mechanics, paygrades E-4 and above, and civilian personnel are eligible for the course. Military NDI Technicians, normally attached to IMAs and Marine Aviation Logistics Squadrons (MALS), are assigned Navy Enlisted Classification (NEC) 7225 or Military Occupational Specialty (MOS) 6044 and are qualified and certified to perform liquid penetrant, magnetic particle, eddy current, ultrasonic, and radiographic methods of inspection. NDI Technicians with three or more year's experience who are currently certified and perform NDI on a regular basis may be authorized by the ACC or TYCOM to train and certify NDI Operators. NDI Technicians are recertified every three years. NDI Technicians failing to maintain proficiency for one year or more require update training by NAVAVNDEPOTs, ACC, or TYCOM designated NDI Specialists prior to recertification. NDI Technicians failing to maintain proficiency for three years or more are required to attend the NAVAVNDEPOT Non-Destructive Inspection Technician Recertification course (N-701-0005) to obtain recertification.
Note: The ACC or TYCOM may waive the three-year experience requirement for NDI Technicians to train and certify NDI Operators.
c. NDI Specialists. NDI Specialists are military and civil service personnel designated by an ACC or TYCOM. NDI Specialists are authorized to provide refresher and specialized training and triennial recertification of NDI Technicians. NDI Specialists are also authorized to train and certify NDI Operators.
2. Maintenance Concept. NDI and the maintenance or repair of inspection equipment is based on preventive and corrective maintenance procedures outlined in OPNAVINST 4790.2G, and is conducted under the three level repair concept (organizational, intermediate, and depot levels) as follows:
a. Organizational. NDI tasks are performed on a scheduled basis depending on aircraft, applicable MRCs, or scheduled maintenance (bulletin) requirements. Unscheduled NDI is conducted on a conditional basis (i.e., hard landings or excessive aerodynamic loading). NDI detected defects discovered by NDI Operators are verified by certified NDI Technicians. When an NDI task or function is beyond the capability of the organizational level NDI Operator, intermediate level NDI Technicians are authorized to provide technical assistance. No repair of NDI equipment is authorized at the organizational level, however NDI Operators are authorized to perform pre-operational and post-operational checks or inspections, and to replenish consumables.
b. Intermediate. Intermediate level NDI tasks are normally performed on components removed from the aircraft. The intermediate level NDI tasks are performed by certified NDI Technicians or NDI Operators who have received training in the specific NDI method per MRCs, Technical Directives, and technical publications. The use of visible dyes for liquid penetrant inspection must be specifically approved by the responsible engineering agency.
The intermediate level maintenance of NDI equipment is conducted by certified NDI personnel at the Aircraft Intermediate Maintenance Department (AIMD), NDI Laboratory Work Center 530, and includes periodic inspection and adjustment, and servicing and replenishment of consumables, per the Handbook of Operations and Service Instructions and applicable MRCs. Troubleshooting procedures are included in the applicable NDI equipment technical manuals. Calibration of NDI equipment is conducted at Precision Measuring Equipment, Work Center 670, per the Metrology Automated System for Uniform Recall and Reporting (MEASURE) data and procedures. Calibration to NDI reference standards prior to operation of NDI equipment is part of the inspection setup procedures. Work Center 530 may accomplish the repair and replacement of defective NDI equipment components.
c. Depot. NDI procedures are performed by qualified and certified NDI personnel. Depot level tasks include maintenance and calibration of NDI equipment (except radiographic equipment), which is beyond the capability of maintenance at the intermediate level. Depot level maintenance includes repair, overhaul, calibration, rebuilding, and refurbishing of NDI equipment and components. Defective X-ray components are repaired at the NAVAVNDEPOT Jacksonville, Florida. Maintenance, repair, and calibration of radiac equipment will be as directed in NAVSEA S0420-AA-RAD-010 and NAVSEA SE700-AA-MAN-210.
d. Interim Maintenance. NA
e. Life-Cycle Maintenance Plan. NDI Equipment falls under the normal calibration program per MEASURE. Each item's specific scheduling requirements are outlined in the Metrology Requirements Lists (METRL) (NA-17-35ATL-1).
3. Manning Concept. The NDI Program has no impact on existing manpower requirements at the organizational, intermediate, or depot level maintenance activities. Enlisted manning for intermediate maintenance activities is based on the total overall assigned workload. Skills required to support the NDI Program are considered to be within the capability of existing NECs and MOSs. Refer to Part II for existing intermediate level manpower requirements.
4. Training Concept. The overall objective of the NDI training program is to ensure the proper quantity and quality of personnel are available with the necessary skills and knowledge to safely perform aircraft maintenance related nondestructive inspections. Training qualifies operators and technicians to perform duties with minimal supervision, both ashore and afloat, under all readiness conditions.
a. Initial Training. NA
b. Follow-on Training. NDI Operator training to perform limited NDI tasks, as well as refresher training, is provided by ACC or TYCOM designated NDI Technicians and Specialists utilizing locally prepared course materials tailored to the specific task. Triennial recertification of NDI Technicians is provided by NAVAVNDEPOTs or by ACC or TYCOM designated NDI Specialists. The Aircraft Nondestructive Inspection Technician Course (C-603-3191) at Naval Air Technical Training Center (NATTC) Pensacola, Florida, provides NDI Technician training for civilian and military personnel. Navy NEC 7225 and Marine Corps MOS 6044 are earned upon successful completion of the course.
