Ordered that the order is affirmed, with costs.
The plaintiff Donna Crawford was injured when a tree on the appellants' property blew over and fell on her car. No liability attaches to a landowner whose tree falls and injures another unless there exists actual or constructive knowledge of the defective condition of the tree ( see Ivancic v Olmstead, 66 NY2d 349, 350-351).
The Supreme Court properly denied the appellants' motion for summary judgment. In response to the appellants' demonstration of entitlement to judgment as a matter of law, the plaintiffs offered the affidavit of their expert which raised a triable issue of fact as to whether the tree presented a "readily-observable manifestation of decay" that should have alerted the appellants to the defective condition ( cf. Ivancic v Olmstead, supra; Harris v Village of E. Hills, 41 NY2d 446; Lahowin v Ganley, 265 AD2d 530).
