What We Intend To Do Is:

Assimilate and evaluate any jobsite date returne'd to us by our customers to determine if there is a mechanical common denominator or circumstance that may contribute to failure of the linear converter unit.

Evaluate the effects of various lubricants and frequency of maintenance by performing additional tests at Pacific Air Products Co.

Inform customers and the Nuclear Regulatory Commission of test results and conclusion reached.

We anticipate receiving all customer responses by the end of March 1984. Evaluation and correlation with the test data that we are presently generating should be complete by mid April 1984.

A final report and 10CFR Part 21 determination will be issued before the end of April 1984.

Sincerely, PACIFIC AIR PRODUCTS C0.
