Appeal and cross appeals from an order of the Supreme Court, Albany County, denying a motion and cross motions for summary judgment. The affidavit submitted by the State of an employee of the boiler manufacturer indicating that the cause of the break was due to a defect in manufacture does not preclude the possibility of other concurring causes and in any event is not alone conclusive on the issue involved.

Accordingly, Special Term correctly determined that factual issues exist which require a plenary trial. Order affirmed, without costs. Herlihy, J. P., Reynolds, Aulisi, Staley, Jr., and Gabrielli, JJ., concur in memorandum by Reynolds, J.
