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
e 2c aircraft obsolescence issues
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
obsolescence management process
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
obsolescence management process5
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
obsolescence management process6
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
case study
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
case study8
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
case study9
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) 861814
    • FISC contacted DLA – Item Manager
    • DMEA Contacted by DLA and Began Redesign of Component P/N (19645) 2158
      • Same as Litton Part Number 861814
      • DMEA Effort Separate from North Island
    • DMEA/DLA Requested North Island Perform Board Level Qualifying Test of Redesigned Part
case study10
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 861814 Approved by Engineering for Removal from SRA
case study11
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
case study12
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
case study13
Case Study
  • Qualification and Bench Testing (cont.)
    • The Second DMEA Prototype 861814 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
case study14
Case Study
  • Royal Singapore Air Force requested PMA Assistance in Obtaining Part for ASN-92
    • P/N 861812 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 861814, 861812, and 861815
    • Forwarded information to PMA-231/NAVICP
case study15
Case Study
  • Opening Sealed Unit Found
    • Extensive Corrosion.
    • One set of leads had completely separated
    • Packaging was holding in moisture.

Sample of Part Number 861815 Corrosion

case study16
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
