Opera v. Hyva, Inc.
Opinion
OPINION of the court
Plaintiff Michael A. Opera fractured his right leg while skiing at Bluemont, a ski area owned and operated by Defendant Hyva, Inc. He and his wife sued defendant, claiming that the injury was caused by a defective binding on skis rented from it. Defendant thereafter impleaded third-party defendant Moog, Inc., the manufacturer of the binding. The jury awarded plaintiffs compensatory and derivative damages on their strict products liability cause of action and it apportioned liability 25% against defendant Hyva, Inc., and 75% against third-party defendant Moog, Inc.
The accident happened on February 12, 1977 when plaintiff, who had only been on skis twice before, was skiing downhill on the beginners’ slope. While doing so, he fell forward and slightly to the right. His left ski binding released but the right one did not and he sustained angulated fractures of the distal third of his tibia and fibula, an [375] injury known as a “boot top” fracture because of its location. It was plaintiff’s claim that the bindings should have released and that defendant’s employees had wrongfully adjusted them too tightly at the time of rental, using a setting which required the application of too much force before releasing. He claims that defendant relied on a defective instruction manual supplied by the manufacturer which recommended binding settings which were “not reasonably safe”. Plaintiff’s evidence on the point included instruction manuals published by Moog after the accident and which contained modifications which plaintiff claimed should have been used in prior manuals.
There should be a reversal. The evidence of postaccident changes in Moog’s manual was admissible to prove the feasibility of using a different system of adjusting the bindings, but the court erred in instructing the jury that these postaccident modifications were evidence that the binding was not reasonably safe when marketed (see Rainbow v Elia Bldg. Co., 79 AD2d 287, affd 56 NY2d 550; Bolm v Triumph Corp., 71 AD2d 429, 436-437; cf. Caprara v Chrysler Corp., 52 NY2d 114).
To state the problem in its simplest terms, bindings for downhill skis should keep the skis fastened on the skier’s foot when he needs them but release so that ski and skier will separate before excessive force, encountered because of a fall or unexpected terrain, is applied to the skier’s body. Excessive force is force that will fracture the skier’s leg bones. And that is the variable factor in adjusting ski bindings; how much force — measured in foot-pounds to account for the leverage of the ski — will the skier’s bones withstand. Obviously, it differs for skiers of different sizes and skiing styles. All binding manufacturers address this problem in the same way. They use various adjustment tables which state the safe force (as discovered by empirical data from laboratory tests) that individual skiers can tolerate. By extrapolation, these readings are transferred from the adjustment table to the manufacturer’s conversion chart which relates it to the proper setting to be used for the binding.
At the time of this accident there were three adjustment tables available for measuring the safe force which could [376] be tolerated by individual skiers. Moog’s manual for the 1976-1977 season used two of them. The first was the I.A.S. system which required measuring the diameter of the skier’s tibia. This was the most precise test of bone strength when done in the laboratory on a denuded bone, but its use presented some obvious difficulties when measurement was made on a human leg in a commercial setting. The second table was called the BfU system which calibrated the release force by considering the skier’s sex, weight and ability (measured by whether the skier was an average or fast skier). The BfU Tables were used by defendant to determine that a D setting should be used on the binding rented to plaintiff.
The third set of adjustment tables, relied on by plaintiff, were known as the Universal Binding Adjustment Tables. They used a “weight and ability” or Lipe
