Review of Ad Hoc Task Force Report (attached)
Jeff Clark reviewed the TF summary report for the group. This will be presented to the entire MSP on 9/10. As part of the discussion, it was emphasized that the CO2 shift needs further investigation as does a potential fuel batch effect. Jeff indicated that he will try to have some updated information on these by the 9/10 meeting.

Review of Alternate Approach (attached)
Jim Rutherford reviewed his presentation with the group. Jim proposes a prediction equation for Pb using bearing weight loss and a prediction equation for Pb2 using bearing weight loss and deltaIR 250-300. Feedback from the group during discussion was generally positive, that this was a good a solution as we've got but some concern was expressed about how specific data would be affected. Concern was also expressed that the new bearings have only been run on one oil (820-2). Greg motioned and Pat seconded to accept Jim's solution, with minor corrections. Vote results: 5 yes, 0 no, 4 abstain. It was noted that a plan will need to be put in place to revisit the correction equations once some reference tests have been completed on the new bearings. Jeff will provide a draft plan for the 9/10 meeting. Jim will re-circulate the proposal with the minor corrections.
