1. DoD Teaming Group E2C2 FST Obsolescence Management Team May 2, 2001
Francisco Rios

2. E2C2 Obsolescence Team
FY00 Charlie Haliscak Assigned PMA-231 Obsolescence Coordinator
PMA-231 DMSMS/Obsolescence Management Plan Developed (February 01)
PMA-231 DMSMS/Obsolescence Team Charter Developed (February 01)
North Island Team Formed and Kick-off Meeting Held 5 February 01

3. E-2C Aircraft Obsolescence Issues
50 of 64 total Aircraft have over 7 years in service
Many Avionics Systems in New Production Aircraft are Configured with Legacy Systems
Many of the Systems in Newer Production Aircraft are recycled from Retired Aircraft
L-304 Mission Computer (Case Study)
APS-125/138/145 Radar WRA’s
Trailing Wire Antenna

4. Obsolescence Management Process
Obsolescence Coordinator Establish Priorities as:
AN/APS-145
AN/APS-138
L-304 Mission Computer
CPU-140A SCADC / NSIU (C-2A Peculiar)
Create Bills of Material/Indentured Parts List (BOM/IPL)
Electronic Format
Electronic BOM/IPL Loaded into TACTRAC
Appoint Server Administrator

5. Obsolescence Management Process
Identify Obsolete Parts or Those at Risk
TACTRAC Output Reports (Green/Yellow/Red Format)
Use Other Tool to Resolve Not Reported Parts (Haystack, Parts Plus, etc…)
May Require Re-Formatting BOM/IPL and Re-Loading
Resolve Unreported Parts Due to Suppliers or SCD’s
Convert SCD’s to Manufacturer or Generic P/N’s or find NSN’s
Re-Load BOM/IPL

6. Obsolescence Management Process
Assess Component/SRA/WRA/System Availability and Demand Rates
Requires Logistics Analysis
Use Data from USN Fleet Maintenance (NALDA)
Also Depot Usage Data

7. Case Study E-2C Mission Computer Upgrade Planned
MCU/ACIS, Only for New Production Aircraft
MC RePLACE Planned for E-2C GR II
Currently Unfunded?
No Retrofit for Group I Aircraft

8. Case Study
In 1998 Litton Industries discontinued support for L-304 Mission Computer
North Island visited Litton and Tagged Inventory
All Inventory Turned over to N-G
In the Mean Time, components for L-304 were Becoming Scarce
Shop Request Alerted Engineering of L-304 Component Availability Issues

9. Case Study
Components made by DDC used on L-304 MC were not in Production/Available
North Island Production Contacted FISC regarding Litton P/N (19645)
FISC contacted DLA – Item Manager
DMEA Contacted by DLA and Began Redesign of Component P/N (19645) 2158
Same as Litton Part Number
DMEA Effort Separate from North Island
DMEA/DLA Requested North Island Perform Board Level Qualifying Test of Redesigned Part

10. Case Study
Qualification and Bench Testing performed at NADEP North Island Feb – March 2001
First Built a Golden SRA to Test Unit in Circuit
SRA was as Close to Center Test Values as Possible.
After Witnessing Test/Values, P/N Approved by Engineering for Removal from SRA

11. Case Study Qualification and Bench Testing (cont.)
First Article Inserted into SRA
Initial Test Discovered Inconsistencies in First Article Component
Thought to be Circuit Trace Problem

12. Case Study Qualification and Bench Testing (cont.)
A Second Unit was Produced by DMEA and Rushed to North Island
Recommended NOT to Encase New Item

13. Case Study Qualification and Bench Testing (cont.)
The Second DMEA Prototype was received March 16th
Testing Began March 19th
End to End Testing of SRA Found No Faults
Bench Testing Results Forwarded to DLA/NAVICP/PMA-231
MIL-Qual Testing to be Performed by DMEA
North Island Recommended MIL-Q-883

14. Case Study
Royal Singapore Air Force requested PMA Assistance in Obtaining Part for ASN-92
P/N no Longer Supported by Litton
PMA Contacted North Island for Assistance
North Island Contacted Litton for Spec of Part
North Island noticed ASN-92 Part, also made by Litton, was Common to L-304 MC
Found Component RSAF was looking for was Family Member of Part Recently Redesigned
North Island Already Affected by Unavailability of Litton P/N , , and
Forwarded information to PMA-231/NAVICP

15. Sample of Part Number 861815 Corrosion
Case Study
Opening Sealed Unit Found
Extensive Corrosion.
One set of leads had completely separated
Packaging was holding in moisture.
Sample of Part Number Corrosion

16. Case Study
North Island Requested NAVICP/DLA Response for Navy and FMS Issues
NAVICP Requested DMEA Quote on Fourteen Components
NAVICP has received bid for rest of Components
North Island Awaiting Funding Decision
Potential candidates for Rapid Retargeting
Would Not Help Singapore Issue
