unreasonable endeavor, i.e. defendants themselves were not acting unreasonably, but the operation of the airport had a substantial and unreasonable impact on plaintiffs’ enjoyment of their property.
Defendants further argue that because the trial court found that noise from takeoffs and landings interfered with only about two to four and a half minutes of plaintiffs’ day, this fails as a matter of law to constitute substantial injury or interference. Again, the trial court’s findings of fact were not directed towards the sufficiency of the evidence to support the jury’s verdict, therefore, defendants cannot rely upon these findings of fact to attack that verdict. Further, as this is a question of sufficiency of the evidence, this issue is not to be decided as a matter of law. In re Will of Buck, 350 N.C. 621, 516 S.E.2d 858 (1999).
Defendants next argue that the trial court erred in denying their Rule 59 motion because the evidence at trial was insufficient to support the jury verdict. Our standard of review for this issue is abuse of discretion. Id. “ ‘An appellate court should not disturb a discretionary Rule 59 order unless it is reasonably convinced by the cold record that the trial judge’s ruling probably amounted to a substantial miscarriage of justice.’ ” Anderson v. Hollifield, 345 N.C. 480, 483, 480 S.E.2d 661, 663 (1997) (quoting Campbell v. Pitt County Mem’l Hosp., Inc., 321 N.C. 260, 265, 362 S.E.2d 273, 275 (1987)).
Upon our review of the record, we are not reasonably convinced that the trial court’s ruling probably amounted to a substantial miscarriage of justice. Nowhere in defendants’ argument do they contend that the trial court committed an abuse of discretion in denying their Rule 59. motion, and we hold that there was none. This argument is without merit.
Because defendants have not argued their other assignments of error in their brief, they are deemed abandoned. N.C. R. App. P. Rule 28(b)(6) (2003).
Plaintiffs’ Appeal
[8] In plaintiffs’ first argument, they contend that the trial court erred in denying their motion for a permanent injunction, and further erred in granting defendants’ request for an avigation easement. For the reasons stated below, we remand this case to the Superior Court of Transylvania County for a new trial on damages, and a new injunction hearing.
