The pilots stated that approach and landing were normal. During landing rollout, about 2,000 feet down the runway, the brakes became ineffective. The aircraft continued to roll off the end of the runway, down an embankment, across a 4 lane road, and came to rest in a drainage ditch. Post-crash examination of the main landing gear brakes showed that 3 out of the 4 brake assemblies were worn beyond allowable limits and all 4 antiskid wheel generators were not producing voltage within the allowable limits. The outboard right main tire had failed during landing roll do to the antiskid becoming inoperative due to the low voltage of the wheel generator. The airplane had received an A-1 through A-6 inspection 2 days before the accident and this was the first flight since the inspection. The A-5 inspection requires inspection of the landing gear brake assemblies for wear, cracks, hydraulic leaks, and release.

On September 25, 1999, about 1726 Hawaiian standard time, Big Island Air flight 58, a Piper PA-31-350 (Chieftain), N411WL, crashed on the northeast slope of the Mauna Loa volcano near Volcano, Hawaii. The pilot and all nine passengers on board were killed, and the airplane was destroyed by impact forces and a postimpact fire. The sightseeing tour flight was operating under 14 Code of Federal Regulations Part 135 as an on-demand air taxi operation. A visual flight rules flight plan was filed, and visual meteorological conditions existed at the Keahole-Kona International Airport, Kona, Hawaii, from which the airplane departed about 1622. The investigation determined that instrument meteorological conditions prevailed in the vicinity of the accident site.

During the final approach, while executing a VOR-A instrument approach, the airplane landed hard, collided with the runway VASI display, and caught fire. The airplane had received radar vectors for the approach and was turned to a 20-degree intercept for the final approach course when 2.5 miles from the initial approach fix. Radar track data showed the airplane continued inbound to the field slightly left of course with a ground speed varying between 135 and 125 knots and a descent rate of approximately 700 feet per minute. The pilot said he descended through the clouds about 850 feet above ground level and saw the airport approximately 1 to 2 miles ahead. He noticed that he was left of the runway centerline and corrected to the right. He realized that he had overcorrected and turned back to the left. The pilot reported that he felt that the approach was stabilized although the descent rate was greater than usual. The airplane impacted the ground about 1,000 feet from the approach end of the runway abeam the air traffic control tower on an approximate heading of 185 degrees. The impact collapsed the landing gear and the airplane slid forward another 1,000 feet down the runway and came to rest approximately midfield on the runway. The pilot stated that he had not experienced any mechanical problems with the aircraft or the navigation equipment prior to the accident. A Special Weather Observation taken at the time of the accident contained the following: sky condition overcast at 500 feet; winds from 230 degrees at 3 knots; visibility 2 miles.

The flight was cleared for a localizer approach to runway 32 at Newnan-Coweta County Airport during dark night conditions. About 8 minutes later the pilot reported to air traffic control that he had missed approach and would like to try another approach. The flight was radar vectored to the final approach course and again cleared for the localizer runway 32 approach. The flight was observed on radar to continue the approach until a point about 4 nautical miles from the airport, at which time radar contact was lost. The last observed altitude was 1,600 feet msl. The aircraft collided with 80-foot tall trees, while established on the localizer for runway 32, about 1.3 nautical miles from the runway. About the time of the accident the weather at the airport was reported as a cloud ceiling 200 feet agl, and visibility .75 statute miles. Post crash examination of the aircraft structure, flight controls, engines, propellers, and systems showed no evidence of pre-crash failure or malfunction.
