Opinion

FERNANDEZ, Judge.

Appellant Steve McGuire was severely burned on May 29, 1979, while he was operating a Caterpillar 988 front-end loader. His action against the manufacturer, Caterpillar Tractor Company (the only defendant), was tried to a jury on a strict liability theory of defective design in the routing of the main hydraulic hose, and the jury found for McGuire in the amount of $650,000. The court granted Caterpillar’s motion for judgment notwithstanding the verdict as well as an alternative motion for new trial.

On appeal McGuire contends 1) the court erred in granting judgment n.o.v., 2) the court erred in alternatively granting Caterpillar a new trial, and 3) the court committed other errors during the trial. We agree that the court erred in granting the judgment n.o.v., affirm the ruling granting a new trial and find that no reversible errors were committed during trial.

The loader was manufactured in November of 1971 and delivered to McGuire’s employer, Union Rock and Materials Corporation, in January 1972. Union Rock purchased the loader without either a firewall or canopy to separate the operator from the engine area and without a seat belt. The loader is a large earth-moving machine with a hydraulically-powered steering system, brakes and bucket. The hydraulic system consists of a hydraulic pump, several hydraulic hose assemblies and various attachments.

On the date of the accident the main hydraulic hose (hereafter “hose”) suddenly ruptured, and the hydraulic fluid ignited, causing McGuire’s injuries. The hose is a composite of a rubber compound and sever *422 al separate layers of steel wire. The end of the hose nearest the operator is mounted by a 90-degree stem fitting on the pump which operates the hydraulic system. The end away from the operator is mounted by a 67V2-degree stem fitting on the junction block, which is located in the lower portion of the engine area. The hose is about five-and-a-half feet long and is routed along the timing gear housing area. The hose burst at the point where it crossed the timing gear housing because contact with the housing had caused a hole in it.

In February of 1972 Caterpillar had issued a change order adding two inches to the length of the hose. The accident hose had been replaced in March of 1975 by a hose fabricated by Empire Machinery Company, an authorized dealer for Caterpillar. Empire also sold two stem fittings to Union Rock at the same time. Later it was learned that, instead of the 67V2-degree stem fitting, a 45-degree stem fitting had been substituted. Except for this fitting, the replacement hose complied with the change order.

Granting of Judgment N.O.V.

McGuire’s action initially was based on negligence and strict liability theories of a defective seat belt, the lack of a firewall or canopy separating the operator from the engine area, and the defective design in the routing of the main hydraulic hose. Caterpillar’s motion for directed verdict was granted as to the defective seat belt and lack of firewall theories. The court submitted the case to the jury on the single question of whether the design of the hose routing was defective.

Arizona has adopted Restatement (Second) of Torts § 402A (1965) on strict liability, which reads as follows:

“(1) One who sells any product in a defective condition unreasonably dangerous to the user or consumer or to his property is subject to liability for physical harm thereby caused to the ultimate user or consumer, or to his property, if
(b) it is expected to and does reach the user or consumer without substantial change in the condition in which it is sold.” (Emphasis added.)

See also O.S. Stapley Co. v. Miller, 103 Ariz. 556, 447 P.2d 248 (1968). Caterpillar argues that the use of the 45-degree stem fitting instead of the 67V2-degree fitting was a substantial change which relieved it of any liability. The cases are not clear as to exactly what constitutes a substantial change. Kuhnke v. Textron, Inc., 140 Ariz. 587, 684 P.2d 159 (App.1984). That fact is also recognized in comment p to § 402A. In Kuhnke, Division One of this court followed the approach of other jurisdictions which analyze the concept of substantial change in terms of an intervening superseding cause and adopted the district court’s assessment in Southwire Co. v. Beloit Eastern Corp., 370 F.Supp. 842 (E.D. Penn.1974), that “such an approach implies that a plaintiff’s failure to negate substantial change is the same as saying that plaintiff failed to prove proximate cause, because they [sic] failed to negate a break in the causal connection between the original defect and the ultimate injury.” 140 Ariz. at 590, 684 P.2d at 162. The court found implicit approval of this approach in O.S. Stapley Co., where our supreme court said, “[i]t is clearly apparent that the product failed to reach the user without some change which may have been substantial, and it is conceivable that such alteration may have been the proximate cause of the accident and of the plaintiff's injuries.” 103 Ariz. at 560, 447 P.2d at 252. Division One held in Kuhnke that “once a defendant comes forward with some evidence of substantial change, the burden is on the plaintiff to show no substantial change,” 140 Ariz. at 590, 684 P.2d at 162, and if he fails, plaintiff loses.

Here there was no question that a change had been made, and both parties’ experts testified that the change resulted in less clearance for the hose. However, McGuire’s expert testified that it was irrelevant whether a 45-degree fitting or a 6714-degree fitting was used because the hose could rub against the housing with either, *423 which meant it was a defective design. We find that McGuire’s expert’s opinion was sufficient evidence that the change was not the proximate cause of injury so as to require submission of the issue to the jury. A motion for judgment notwithstanding the verdict is “a renewal of [a] motion for an instructed verdict, and is designed to permit the trial court, after more mature deliberation, to reverse its ruling in denying the motion for an instructed verdict.” In re Schade’s Estate, 87 Ariz. 341, 348, 351 P.2d 173, 178 (1960). A motion for judgment n.o.v. is properly granted when the evidence would not permit a reasonable person to reach the verdict returned by the jury. Lemer v. Brettschneider, 123 Ariz. 152, 598 P.2d 515 (App.1979); Huggins v. Deinhard, 127 Ariz. 358, 621 P.2d 45 (App.1980). Here the trial court, in denying Caterpillar’s motion for directed verdict, said “I believe that even if Caterpillar’s design and instructions were followed to the letter there was still a defect.” He later changed his mind. We find that his initial decision was the correct one.
