The A/F 27T-10 provides Aircraft Intermediate Maintenance Departments (AIMD) both ashore and afloat increased capabilities to perform diagnostic testing, verification, and functional acceptance of hydraulic components. The A/F 27T-10 meets the requirements for hydraulic components with higher fluid temperature, pressure, and flow rate.

2. Foreign Military Sales. No Foreign Military Sales (FMS) or additional procurements are currently planned.

E. DEVELOPMENTAL TEST AND OPERATIONAL TEST. The A/F 27T-10 completed Developmental Testing at AIMD Naval Air Station (NAS) Oceana, Virginia, in April 1997, but encountered software configuration problems. These software problems have been corrected and no new Developmental Tests will result. No Operational Test is required.

F. AIRCRAFT AND/OR EQUIPMENT/SYSTEM/SUBSYSTEM REPLACED. The A/F 27T-10 is replacing the existing HCT-10 Hydraulic Component Test Stand, hereafter referred to as the HCT-10.

G. DESCRIPTION OF NEW DEVELOPMENT

1. Functional Description. The A/F 27T-10 provides AIMD, both ashore and afloat, increased capabilities to perform diagnostic testing, verification, and functional acceptance of hydraulic components. The A/F 27T-10 provides hydraulic, electrical, and pneumatic power, and the instrumentation and control necessary for diagnostic testing and verification of functional performance of aircraft hydraulic components. The A/F 27T-10 is replacing the HCT-10, which does not meet the increased requirements for hydraulic components of modern aircraft in Navy and Marine Corps inventories. The A/F 27T-10 consists of the following three major components.

a. Hydraulic Console. The Hydraulic Console (HC) provides the Unit Under Test (UUT) with the necessary input test parameters to perform functional tests through use of electrical and hydraulic adapters. It also acts as a work bench area by means of mechanical adapters.

b. Electronic Control Console. The Electronic Control Console (ECC) is a microcomputer controlled console that provides all the necessary electrical interfacing with the HC to accomplish hydraulic control, signal acquisition and control, critical fault monitoring, and any other electrical interfacing necessary to functionally test a UUT. A minimum number of required operator actions are permitted. A Built-In Test (BIT) capability is included so essential A/F 27T-10 internal operating systems may be determined operational. The BIT feature is capable of isolating faults to the printed circuit board on the ECC and to the shop replaceable assembly on the HC. To assist maintenance personnel through pre-operational checks and preventive and corrective maintenance tasks, a computer-aided maintenance function has been added as one of the operating modes.

c. Heat Exchanger. The Heat Exchanger regulates the hydraulic oil temperature within a range of 90 to 160 degrees Fahrenheit. This configuration employs an oil to water and oil to air method. Further system data for the A/F 27T-10 is as follows:

2. Physical Description. The A/F 27T-10 (consisting of the HC, ECC, and the Heat Exchanger) weighs 5,775 pounds and is designed for ship and shore-based applications.

a. Hydraulic Console. The HC contains hydraulic components, pneumatic components, the test sink, the static pressure chamber, the heat exchanger, remote electrical outlets, accessory storage, and an instrumentation panel. The HC dimensions are 84" long x 48" wide x 74" high.

b. Electronic Control Console. Through human interface, the ECC automatically controls the test parameters needed to perform the necessary tests. The ECC dimensions are 44" long x 36" wide x 74" high.

c. Heat Exchanger. Heat Exchanger regulates the hydraulic oil temperature within a range of 90 to 160 degrees Fahrenheit. This configuration employs an oil to water and oil to air method.

3. New Development Introduction. The A/F 27T-10 is being introduced through new production. Sixty-four units are being procured, to include four pre-production units and two production lots of 30 each. Site activation scheduling is currently under review and will be incorporated into future updates of this NTSP.

4. Significant Interfaces. The A/F 27T-10 electrical configuration is designed to be compatible with shipboard Alternating Current (AC) power (440 Volts Alternating Current (VAC), 60 Hertz (Hz), 3 phase) and shore AC power (460 ± 5% VAC, 60 Hz, 3 phase).

5. New Features, Configurations, or Material. Not applicable (NA)

H. CONCEPTS

1. Operational Concept. The A/F 27T-10 will be operated at the intermediate maintenance level by Navy Aviation Structural Mechanic Hydraulics or Structures (AMH or AMS) rating personnel with NEC 7212 and assisted as necessary by the Aviation Electronics Technician (AT) or Aviation Electrician's Mate (AE) with NEC 7173. Marine Corps Aircraft Hydraulic/Pneumatic Mechanic personnel with Military Occupational Specialty (MOS) 6062 will operate and maintain the A/F 27T-10, and will be assisted by Aircraft Electrical/Instrument/Flight Control Systems Technician Personnel with MOS 6432, 6433, or 6434.

2. Maintenance Concept. The A/F 27T-10 will be maintained at the intermediate maintenance level by AMH or AMS rating personnel with NEC 7212. Marine Corps A/F 27T-10 maintenance will be performed by Aircraft Hydraulic/Pneumatic Mechanic personnel with MOS 6062.

a. Organizational. NA

b. Intermediate

(1) Preventive Maintenance. Preventive maintenance includes pre-operational inspections, replenishment of consumable fluids, adjustment of pressures, cleaning, servicing, and corrosion prevention, inspection, and control.

(2) Corrective Maintenance. Corrective maintenance consists of fault isolation, removal and replacement of defective assemblies and components, and the repair of selected defective assemblies. To assist maintenance personnel performing these tasks, a computer-aided maintenance function has been added as one of the operating modes.

c. Depot. Depot level maintenance consists of rework and overhaul of the A/F 27T-10, and repair of components determined to be beyond the intermediate level capability. The depot maintenance contract has been awarded to DynCorp, Reston, Virginia. The contract is for the service life of the A/F27T-10.

d. Interim Maintenance. Program Manager, Air (PMA)260 will arrange for appropriate interim maintenance prior to the Navy Support Date of September 2001. Technical assistance is being provided by Naval Aviation Technical Data and Engineering Service Command (NATEC) personnel.

e. Life Cycle Maintenance Plan. NA

3. Manning Concept. Operation and maintenance of the A/F 27T-10 will be accomplished with no change to current manpower requirements.

4. Training Concept. The two existing training sites for the HCT-10 are being used for A/F 27T-10 training. They are:

• Maintenance Training Unit (MTU) 1007 Naval Maintenance Training Unit (NAMTRAU) Oceana, Virginia
• MTU 1038 NAMTRAU Lemoore, California

To meet the requirements for the A/F 27T-10, a new follow-on training course, C-690-3211, has been developed to replace the current HCT-10 training course, C-602-3191, and will be Ready For Training as of April 2001. All required training will be provided to Navy AMH and AMS personnel with NECs 7212 and Marine Corps personnel with MOS 6062. Training covers both operation and maintenance of the A/F 27T-10.

Selected Reserve personnel may earn intermediate level maintenance NECs by attending formal training at NAMTRAUs providing a quota and funding are available, and the student is available to attend the training. Specific guidelines are contained in NAVPERS 18068F Volume II, Chapter IV, Navy Enlisted Classifications.

The established training concept for most aviation maintenance training divides "A" School courses into two or more segments called Core and Strand. Many organizational level "C" School courses are also divided into separate Initial and Career training courses. "A" School Core courses include general knowledge and skills training for the particular rating, while "A" School Strand courses focus on the more specialized training requirements for that rating and a specific aircraft or equipment, based on the student's fleet activity destination. Strand training immediately follows Core training and is part of the "A" School. "A" School graduates going to intermediate level activities attend the appropriate intermediate level "C" School. Intermediate level "C" Schools are not separated into Initial and Career courses.

a. Initial Training. The contractor, Dayton T. Brown, Inc., trained Developmental Test personnel at NAS Oceana in June 1995. The contractor also provided instructor training at its factory in Bohemia, New York in July 1998. NATEC representatives are providing transition training and assistance, on an as required basis, to those activities transitioning from the HCT-10 to the A/F 27T-10. Naval Air Warfare Center Aircraft Division Lakehurst (NAWCADLKE) is also providing on-site transition training and technical support during installation. The NAWCADLKE A/F27T-10 installation team will remove the old HCT-10, install the new A/F 27T-10, perform the initial turn on and calibration, and provide initial operational training.

b. Follow-on Training. The A/F 27T-10 course, C-690-3211, is replacing the existing HCT-10 and Limited Aircraft Component Intermediate Maintenance course, C-602-3191, in training tracks D/E-602-4007 for USMC personnel and in training track D/E-602-4008 for USN personnel. The HCT-10 training course will be discontinued once fleet implementation is completed.

c. Student Profiles

d. Training Pipelines. The following training tracks apply and are available in the OPNAV Aviation Training Management System (OATMS). These tracks are being modified by replacing course number C-602-3191, the HCT-10 course, with the new A/F 27T-10 course, C-690-3211. Upon completion of one of these tracks, Navy personnel will be awarded NEC 7212. Marine Corps personnel complete D-602-4007 and are awarded MOS 6062. Navy Aviation Electrician's Mates and Aviation Electronics Technicians with NEC 7173 and Marine Corps personnel with MOSs 6432, 6433, or 6434 do not require A/F 27T-10 training.

I. ONBOARD (IN-SERVICE) TRAINING. Identify onboard or in-service training to be provided such as Personnel Qualification Standards (PQS), Computer Based Training (CBT), embedded training, pre- and post-delivery crew watch-standing, and the Maintenance Training Management and Evaluation Program (MATMEP).

1. Proficiency or Other Training Organic to the New Development

a. Maintenance Training Improvement Program. The Maintenance Training Improvement Program (MTIP) is used to establish an effective and efficient training system responsive to fleet training requirements. MTIP is a training management tool that, through diagnostic testing, identifies individual training deficiencies at the organizational and intermediate levels of maintenance. MTIP is the comprehensive testing of one's knowledge. It consists of a bank of test questions managed through automated data processing. MTIP will be replaced by the Aviation Maintenance Training Continuum System (AMTCS). Current planning is for AMTCS to begin full implementation for fleet deployment in March 2001.

b. Aviation Maintenance Training Continuum System. AMTCS will provide career path training to the Sailor or Marine from their initial service entry to the end of their military career. AMTCS is planned to be an integrated system that will satisfy the training and administrative requirements of both the individual and the organization. The benefits will be manifested in the increased effectiveness of the technicians and the increased efficiencies of the management of the training business process. By capitalizing on technological advances and integrating systems and processes where appropriate, the right amount of training can be provided at the right time, thus meeting the CNO's mandated "just-in-time" training approach.

Technology investments enable the development of several state-of-the-art training and administrative tools: Interactive Multimedia Instruction (IMI) for the technicians in the Fleet in the form of Interactive Courseware (ICW) with Computer Managed Instruction (CMI) and Computer Aided Instruction (CAI) for the schoolhouse.

Included in the AMTCS development effort is the Aviation Maintenance Training Continuum System - Software Module (ASM) which provides testing [Test and Evaluation (TEV)], recording [Electronic Training Jacket (ETJ)], and a Feedback system. The core functionality of these AMTCS tools are based and designed around the actual maintenance-related tasks the technicians perform, and the tasks are stored and maintained in a Master Task List (MTL) data bank. These tools are procured and fielded with appropriate COTS hardware and software, i.e., Fleet Training Devices (FTD) - Laptops, PCs, Electronic Classrooms (ECR), Learning Resource Centers (LRC), operating software, and network software and hardware.

Upon receipt of direction from OPNAV (N789H), AMTCS is to be implemented and the new tools integrated into the daily training environment of all participating aviation activities and supporting elements. AMTCS will serve as the standard training system for aviation maintenance training within the Navy and Marine Corps, and is planned to supersede the existing MTIP and MATMEP programs. AMTCS implementation will begin with the F-14, E-2C, and all models F/A-18 aircraft. For more information on AMTCS refer to PMA205-3D3.

2. Personnel Qualification Standards. NA

3. Other Onboard or In-Service Training Packages. Marine Corps onboard training is based on the current series of MCO P4790.12, Individual Training Standards System and MATMEP. This program is designed to meet Marine Corps, as well as Navy OPNAVINST 4790.2 series, maintenance training requirements. It is a performance-based, standardized, level-progressive, documentable, training management and evaluation program. It identifies and prioritizes task inventories by MOS through a front-end analysis process that identifies task, skill, and knowledge requirements of each MOS. MTIP questions coupled to MATMEP tasks will help identify training deficiencies that can be enhanced with refresher training. (MATMEP is planned to be replaced by AMTCS.)
