Cessna 550 Citation II

On final approach to Ashaka Airport in poor weather conditions, the crew apparently initiated a go-around procedure when the aircraft crashed short of runway threshold. All three occupants were killed.

During arrival, flight was vectored for NDB runway 06 approach, and advised Raleigh-Durham weather was 500 feet overcast, visibility 3 miles with fog, wind from 140° at 12 knots, altimeter 30.01. After clearance for approach, aircraft crossed final approach fix (faf) at 2,100 feet msl. Radar service was terminated and frequency change was approved. When aircraft did not arrive, search was initiated. The wreckage was found about 2.5 miles southwest of runway 06, where aircraft hit trees and crashed. Elevation of crash site was about 600 feet msl. MDA for approach was 1,160 feet msl (with local altimeter setting; 1,260 feet with Raleigh-Durham setting). Exam revealed aircraft hit trees, while on runway heading in wings level attitude; configured for landing. No preimpact part failure/malfunction was found. Toxicological check of pic's blood showed 0.10 mg/l of diazepam and 0.09 mg/l of nordiazepam. Check of his urine showed metabolite of marijuana (11- nor-delta-9-tetrahydrocannabinol-9-carboxylic acid) at level of 0.117 mg/l. After surgery for malignant lymphoma (feb 89), pic was restored to flight status on 8/9/89 and cleared for pic duty one week later. He continued flying tho he received maintenance chemotherapy and associates noted that he tired easily. Both occupants were killed.

Witnesses reported aircraft was high during approach and landed nosewheel 1st about 1,600 feet beyond threshold, then became airborne and bounced 2 times. Pilot stated that before touchdown, he started to 'spool up' engines, but noted lack of response, then retarded throttles and landed. He said he applied brakes and selected 'full reverse' and noted no response. Reportedly, nosewheel 'skipped into air' while aircraft still had flying speed. With insufficient runway remaining to stop, he elected to stow reversers and began go-around. He noted no response from engines, tho aircraft had became airborne. Aircraft then settled beyond departure end of runway and crashed on rough terrain. Examination revealed engines had ingested twigs, grass and dirt. Reverse load limiters (l/l) on both engines were found in tripped position. Flight man stated that to avoid actuation of l/l, do not advance primary throttle after returning reverse thrust lever to stow until unlock light is out; maint required to reset actuated l/l. L/l was incorporated on thrust reverser to reduce engine power to idle, if inadvertently deployed in flight. During post-accident check, both engines were operated to 85% after l/l reset.

Following a wrong approach configuration, the aircraft descended too high on the glide and landed too far down a wet runway. After touchdown, unable to stop within the remaining distance (insufficient distance available and poor braking action due to a wet runway surface), the aircraft overran and collided with a dyke. All seven occupants were rescued while the aircraft was damaged beyond repair.

After landing on runway 31L, the aircrew of N100VV requested clearance to turn off to the right at midfield onto runway 22. The request was approved and the aircrew was instructed to use caution for a Cherokee proceeding from the opposite direction. The pilot of N100VV stated that after he turned right onto runway 04/22 and was clear of the Cherokee, he attempted to contact the tower to advise of his intentions. However, the frequency was too busy, so he switched to the ground frequency and transmitted that he was 'off 31L, going to Atlantic.' This transmission ended just as N100VV was entering the intersection of runway 22 and 31R. Just prior to that, N222WL had been cleared for takeoff on runway 31R and had begun its takeoff roll. N222WL was at approximately 70 knots when its aircrew saw N100VV starting to cross the active runway. The pilot of N222WL attempted to takeoff and avoid a collision, but was unable to clear N100VV. N222WL crashed and slid to a stop approximately 400 feet beyond the impact point with N100VV, then burned. All three occupants escaped uninjured.
