Landing (descent or approach)

The approach to Cobán Airport was initiated in poor weather conditions with limited visibility due to fog. Too low, the aircraft struck trees and crashed in a wooded area located 7,2 km short of runway. Both pilots were killed. They were completing a positioning flight from Guatemala City.

The pilot was conducting an approach to runway 8, during which the left wing contacted the ground approximately 75 feet from the approach end of the runway. The airplane came to rest about 160 feet down the runway, and off the right side. A pilot who landed on runway 26, about 30 minutes prior to the accident flight, stated that the winds were out of the northwest at 15 knots with gusts, and he experienced plus and minus 10 knots on the airspeed while on final approach. The winds 19 miles to the east, at 1045 eastern standard time, were reported from 310 degrees at 15 knots with gusts up to 20 knots. An AIRMET was issued at 0345, with an advisory for occasional moderate turbulence below 8,000 feet. The AIRMET was reissued at 0945, with the added advisory of, 'Low level wind shear potential over the Boston Area Forecast area east of an Erie-Bristol line due to gusty northwesterly surface winds. Conditions ending by 1600.' An FAA Inspector examined the wreckage and found no preimpact anomalies with the airplane.

A witness heard the aircraft pass King Island aerodrome at 0455 EST at the same time as he noticed the pilot-activated 10/28 runway lights illuminate. The pilot reported to Melbourne Control that he would be completing a runway 10, non-directional beacon (NDB) approach. A short time later he broadcast that the aircraft was at the minimum descent altitude, which is 640 feet above mean sea level (AMSL) for a runway 10 NDB approach. He also broadcast that there was a complete cloud cover. The aircraft did not enter a missed approach procedure but was heard to fly towards the south-east from overhead the NDB, which is located 1.3 km south-south-west of the centre of runway 10/28. A second witness, located near the NDB site, reported observing the aircraft's lights to the south-east. At 0507 a farmer heard the aircraft pass low over his house shortly before it crashed into trees, 3.5 km south-east of the aerodrome. The first responders arrived at the accident site at about 0530. The pilot had not survived.

While approaching Ensenada Airport by night and foggy conditions, the crew failed to realize his altitude was insufficient when the aircraft struck a hill located few km from the airport. The aircraft was destroyed upon impact and all eight occupants were killed. It is believed that the crew did not receive any clearance to approach Ensenada Airport and continued the descent at an insufficient altitude.

En route from Imperatriz to Fazenda Matary, the captain informed the copilot he would perform training upon arrival as there are no passengers on board. On descent, he informed ATC he would perform a touch-and-go manoeuvre. With the flaps down at 15°, the aircraft landed at a speed of 125 knots, about 10 knots above the speed reference of 116 knots. After touchdown, the captain changed his mind and decided to perform a complete stop without informing the copilot. The copilot noted that the speed was dropping so he decided to increase engine power to takeoff. Shortly later, the captain reduced power and initiated a braking procedure. Unable to stop within the remaining distance, the aircraft overran and came to rest few dozen metres further, bursting into flames. All three occupants escaped uninjured while the aircraft was destroyed by a post crash fire.

After landing at Luremo, the aircraft was unable to stop within the remaining distance, overran, lost its nose gear and came to rest few dozen metres further. All five occupants evacuated safely while the aircraft was damaged beyond repair.

The pilot reported that as he overflew the Tri-City airport, Tennessee at 9,000 feet, the right engine power slowly decreased. The airplane was in the clouds with an outside air temperature of about zero degrees Celsius. Right engine manifold heat was applied for a few seconds, with no noticeable difference in engine performance. The right magnetos were also checked with no obvious malfunctions noted. A descent for landing was initiated to the Tri-City airport and manifold heat was applied and removed several times, with no appreciable effect. On short final approach, when the landing gear was extended, the right main gear did not indicate down. There was insufficient time to perform the emergency gear extension procedure. A go-around was initiated, during which the pilot discovered that the left manifold heat control was now stuck in the 'ON' position. The pilot stated that with less than full power available on the left engine, and the right propeller unfeathered, the airplane could be climbed to about 200 feet. He flew the airplane until terrain clearance was no longer possible, then landed in a field, gear up. The airplane slid into trees and was substantially damaged.

The pilot and 2 nurses departed IFR to transport a patient from another location. During the initial climb, the pilot observed a gear unsafe light. He requested clearance to an area of VFR conditions to address the gear problem. Subsequently, the gear was manually extended with safe gear indications. The flight department requested that the pilot return to base. The pilot obtained an IFR clearance to return for an ILS approach. After handoff to the tower, he was requested to report the FAF inbound after an eastbound procedure turn. That was the last communication from the pilot. Subsequently, the aircraft crashed on the southeast side of Humphreys Peak at an elevation of about 10,500 feet and about 10 miles west of the final approach course. Wreckage was scattered along a heading of 230 degrees. There was evidence that the airplane was in a steep descent when it crashed. Radar data revealed an outbound track west of the published course and no procedure turn. The weather was IMC with light snow and rain. Moderate to severe turbulence was forecast and confirmed by other pilots. The winds at 10,000 feet were forecast to be 50 knots out of the southwest. Moderate turbulence and light rime ice had been reported along the ILS approach course before to the accident time.

Following an uneventful flight from Wellington, the pilot started the descent to Picton-Koromiko Airport in good weather conditions. On final, at an altitude of 1,700 feet, the single engine aircraft entered clouds and struck the slope of Mt Robertson located 10 nm northeast of Blenheim. All five occupants were killed and the pilot was seriously injured.

Following an uneventful cargo flight from Johannesburg, the crew started the approach to Harare Airport in poor weather conditions with heavy rain falls. After landing on runway 05, the aircraft encountered difficulties and was unable to stop within the remaining distance (runway 05 is 4,750 metres long). It overran, lost its nose gear and came to rest. All five crew members escaped uninjured and the aircraft was damaged beyond repair.
