D-2 Inc. Achieves CAR Level (0) with US Military & DCMA

D-2 Incorporated is extremely pleased to announce that we have acheived the extremely low CAR Corrective Action Request level (0) with the US military under DCMA. This level allows D-2 Inc. with approval by the DCMA to self-inspect.

To achieve this status of CAR Level is a reflection of the quality products and services D-2 Inc provides. Level 0 means we have 0 Corrective Action Requests, which is the highest level of quality possible.

D-2 Inc. will continue to provide the highest level of quality products at the lowest possible price to the US Military, and we are very proud of our current status of level 0 CAR.

A Corrective Action Request (CAR) is sent to a supplier where an item or process is in nonconformity and a remedy is required. CAR’s are normally determined during quality assurance activities. Each organization will have its own specific CAR form, process and procedures.

The DoD has four (4) levels of CARs. The level depends on the severity of the nonconformity and the level of supplier management visibility required to adequately address corrective actions.

  • Level I: Issued for nonconformity that can be corrected on the spot and where no further corrective action response is necessary.  Level I CARs shall be documented and issued to the supplier management level responsible for taking corrective actions.
  • Level II: Issued when contractual nonconformity cannot be corrected on the spot.  As a minimum, nonconformity associated with Critical Safety Item (CSI) critical characteristics and Safety of Flight (SOF) characteristics shall be issued at this level.  Level II CARs should be directed to the supplier management level responsible for initiating corrective actions
  • Level III: Issued to the supplier’s top management to call attention to serious contractual nonconformity.  Repeat nonconformities found within one year for the same single point failure SOF characteristics shall be issued as a Level III CAR. A Level III CAR may be coupled with contractual remedies such as reductions of progress payments, cost disallowances, or business management systems disapprovals, etc. A Level I or II CAR need not be issued before a Level III CAR is generated.  All Level III CARs shall be coordinated with the Contracting Officer.
  • Level IV: Issued to the supplier’s top management when a Level III has been ineffective or the contractual nonconformity is of such a serious nature to warrant contractual remedies such as suspension of progress payments or product acceptance activities, in accordance with applicable Federal Acquisition Regulations (FAR)/Defense Federal Acquisition Regulations Supplement (DFARS) policies and procedures.  Level IV CARs should be addressed to the supplier’s top-level management.

For Level II or higher corrective action requests, the CAR should clearly state that the request should be treated by the supplier as a customer complaint. This will ensure that information is reviewed by the supplier as part of the corrective action system. They shall cite the following minimum requirements for a Supplier’s response:

  • Cause(s) of the nonconformity
  • Actions taken or planned to eliminate the cause(s) and prevent recurrence of the nonconformity
  • Actions taken to correct the specific nonconformity
  • Whether other products are affected, including product already delivered to the customer
  • Action taken to correct the weakness which allowed deficient product to be presented to the government for acceptance
  • Target date(s) for implementation of planned actions

Thanks for reading this post, I hope you found it informative. If you are customer of D-2 Inc. you should be pleased to know we have never received a CAR because our process and our quality are top notch.

D8073 Added to D1655 Appendix X

The world of Aviation Turbine Kerosense testing and qualification took another major step forward toward increased precision and automation of the aviation turbine fuel certification process. The D-2 Inc. WSI Water Separation Instrument, ASTM Test Method D8073 (IP 624) has been incorporated in D1655. D8073 is an improved method to better determine the ability access the water separation characteristics of aviation turbine. Better assessment allows confidence that fuel will not disarm field water separators, providing users more efficient terminal operations.

The current incorporation is to the non-mandatory section of D1655. This change intended to allow operators to expand field use of the new Method with a goal to gain additional user data to speed D8073 adoption into the mandatory section of D1655 with limits. The most recent revision of ASTM D1655 Revision 18B, December 1, 2018 reflects these changes. Under Appendix X1.13.2 and X1.13.2.2.

The WSI Water Separation Instrument ASTM D8073 is continuing its field testing at multiple locations to further establish the data is reliable and can be used for fuel certification. These test sites include major Oil Company Producers, multiple international locations and branches of the US Military. We welcome all request for demonstration of the D8073 method to your laboratory, please contact our sales team if you would like to schedule a visit.

The WSI is a major improvement over the previous Test Methods. The WSI instrument brings full automation to the ASTM water separation test. Eliminating user error and significantly reducing false positives and false negative results. The team has also developed a comprehensive report on D8073 and its response to a variety of approved and unapproved aviation turbine additives, if you would like a copy of that report please send a request, it can also be found in the ASTM Work Item 57443 collaboration area

For more information on the WSI Instrument please see our product page…

D-2 Inc. Attends the Fuel Contamination Meeting in Dayton OH

D-2 Incorporated attended the Fuel Contamination Task Force in Dayton Ohio, sponsored by American Airlines, for a discussion of fuel contamination issues that could lead to a root cause of ‘TIE’ Throttle Instability Events recently experienced in industry. The goal was to have an open discussion among industry experts combined with focus presentations to help develop diagnostic strategies to find the root cause of these events.

In the discussions the importance of keeping aviation fuel supply’s clean and dry throughout by careful housekeeping of facilities was a recurring theme. Conversations as to how the ASTM D8073 Water Separation Instrument WSI and the JF-1A In Line Conductivity Sensor could form essential elements in maintaining high fuel quality by monitoring fuel through the distribution system were discussed. The conductivity sensor strategically located in the distribution system could give early indication of a TIE fuel contamination event and help lead investigators closer to a root cause. The WSI D8073 using its better precision that existing methods will help to more rapidly detect fuel entrained surfactants and give more rapid indication of fuel impacts on water separation elements.

D-2 Inc. will continue to support the work of fuel contamination task force as they continue to identify the root cause of the issue. We have already identified several instrument opportunities that can not only help this task force, but, also improve fuel terminal facility performance through improved real time “in-line” monitoring of fuel, we will look to develop these over the coming year, so stay tuned!

ASTM D02 Continues steady progress on Specification Listing of D8073-16/IP624 Method, Water Separation Instrument, (WSI).

The ASTM D02 Sub Committee J1 recently approved a ballot to list ASTM D8073/IP624 in D1655.  D8073/IP624 is a new method for “Determination of Water Separation Characteristics of Aviation Turbine Fuel by Small Scale Water Separation Instrument”.   This J1 ballot is now out for voting at the D2 level.  The pending ballot result will be discussed at the next ASTM Meeting in Atlanta in early December.  We will also be having a Working Group meeting during the ASTM session, contact  Madalina Mohtadi <> our working group chair for complete meeting details.  We also appreciated ASTM member support at these critical progress meetings!

The WSI Instrument is a new technology for determining the presence of surfactants and contaminates that are likely to cause a failure in critical water separation filters.  The WSI (D8073/IP624) utilizes 5th Edition Filter material to better predict field filter performance.  The new fully automated measure has higher precision than existing manual methods.  The fully automated measurement greatly reduces operator interaction with the determination, resulting in significant time saving in addition to its improved results.

The D8073/IP624 method is also under review for incorporation in commercial Jet Fuel Specifications by the Canadian Government Safety Board, (CGSB) and other industry regulatory groups.  The US DOD is also in evaluation of the instrument for incorporation into the Military Fuel Specifications, such as JP8.  We will keep you posted here as progress/completion are made. Please contact if you are interested in a demonstration or loaner instrument for your laboratory to gain experience with this critical new method.
