On April 3, 2015, about 2115 Hawaiian standard time, N245RB, a Cessna 206H, was substantially damaged when it veered off the runway during landing at the Honolulu International Airport (HNL), Honolulu, Hawaii. The airplane was registered to and operated by Worldwide Aircraft Leasing Corporation under the provisions of Title 14 Code of Federal Regulations Part 91. The commercial pilot and passenger were not injured. Visual meteorological conditions prevailed and an instrument flight rules flight plan had been filed. The flight departed from Kona International Airport at Keahole (HKO) Kailua/Kona, Hawaii, about 1945. The pilot reported that shortly after landing on runway 4R, he had difficulties controlling the airplane during the landing roll. He stated that the airplane initially drifted slightly to the left; however, when he applied aileron and rudder to correct the drift, the airplane yawed suddenly to the right, and he was unable to counteract it. Subsequently, the airplane exited the runway surface and struck an arrester gear assembly, used by military fighter and trainer aircraft for emergencies. During the accident sequence, substantial damage was sustained to the airplane's right wing strut. The passenger stated that the landing was normal and on centerline. She further stated that shortly after landing, the pilot struggled to maintain control of the airplane. Postaccident examination of the airplane by a Federal Aviation Administration Inspector revealed that the right wing strut was bent about mid-span. Flight control and braking continuity was established with the cockpit controls. The main tires were examined and appeared to be properly inflated with no anomalies observed. The nose wheel tire still remained on its hub, but about a 1/2-inch hole was observed on the side wall, of the inner tube. No additional pre-accident mechanical malfunctions or failures were observed that would have precluded normal operations.
