Circumstances:
During arrival at dawn, the pilot contacted Approach Control about 22 miles from the airport at 8,500 feet and requested an ILS runway 26 approach. The ATIS was reporting 1/8 mile visibility with fog; the minimum published visibility for the ILS landing was 3/4 mile. The controller vectored the aircraft so that it intercepted the ILS localizer at the outer marker at an intercept angle that was 5 degrees greater than the maximum allowable intercept of 30 degrees. The intercept point should have been at least 3 miles further away from the airport. The aircraft was 650 feet above the ILS glideslope at the outer marker (which was outside the ILS glideslope parameter). Instead of making a missed approach, the pilot elected to continue the ILS. As he attempted to intercept the glideslope from above, the airplane entered a high rate of descent and passed through the glideslope. The pilot was arresting the descent, when the airplane collided with level terrain about 1,000 feet short of the runway. After the accident, at 0646 edt, the visibility was 1/16 mile with fog.
Probable cause:
The pilot's improper IFR procedure by not initiating a missed approach at the outer marker, by attempting to intercept the glideslope from above after passing the outer marker, and by allowing the airplane to continue descending after reaching the decision height. Factors relating to the accident were: the adverse weather condition, and the approach controller's improper technique in vectoring the airplane onto the ILS localizer.

Circumstances:
N500AK encountered icing in flight before start of ILS approach. Radar data showed that before reaching outer marker, it slowed in a manner that was consistent with a power reduction (or partial loss of power), then it entered a steep descent and crashed. Examination revealed engines were not operating at impact and that propellers had been feathered. No preimpact part failure or malfunction of engines, propellers or anti-ice system was found. There was evidence that engine inlet anti-ice annunciator lights and stability augmentation system (SAS) fault warning light were illuminated during impact. The engine manufacturer reported that flameouts had occurred in other aircraft, during or following operation in icing conditions, sometimes after descent into warmer air. Flight manual noted that if icing was encountered with anti-ice system off, select continuous ignition and then select engine and propeller heat (1 engine at a time, ensuring first engine was operating satisfactorily before selecting second engine) and engage sas heat. All four occupants were killed.
Probable cause:
Failure of the pilot to follow procedures concerning use of the engine inlet anti-ice system and/or continuous ignition while operating in icing conditions, which resulted in probable ice ingestion and loss of engine power; and the pilot's failure to maintain sufficient airspeed while coping with the engine problem, which resulted in a stall. Factors related to the accident were: darkness, icing conditions, and engine inlet (nacelle) ice.

Aircraft flight hours:

Circumstances:
The twin engine aircraft was completing a night charter flight from Southend to Helsinki, carrying seven passengers and one pilot. On final approach to Helsinki-Vantaa Airport runway 22, the pilot elected to reduce the speed when the aircraft lost altitude, descended below the MDA, struck the ground and came to rest inverted in a snow covered field located about one km short of runway threshold. A passenger was seriously injured while seven other occupants were killed.
Probable cause:
It is believed that the pilot probably encountered difficulties in controlling the altitude and an excessive speed during the final approach procedure. As a result, he retarded engine power by pulling both speed levers backwards. Investigations revealed that the flight idle gate allowing the speed levers to be stopped before being positioned at idle was worn, which allowed the pilot to position both levers to idle position while still on approach. This caused the aircraft to lose speed and altitude and to descend below the minimum descent altitude (MDA) until it struck the ground.
The following contributing factors were reported:
- The pilot did not have sufficient experience on this type of aircraft,
- The pilot's training on such operation was insufficient,
- The accident occurred in demanding instrument flight conditions.

Aircraft flight hours:

Circumstances:
Aircraft was scheduled for an instructional flight. During the weather briefing, the CFI told the FSS specialist that the flight would include engine out practice. Witness statements indicate that the aircraft rolled sharply to the right and nosed down after attaining about 100 feet of altitude during the climb after takeoff. The aircraft struck the ground left prop and left wing tip first, in an inverted flight attitude. During the post accident investigation, the right engine power lever was subjected to lab exam and it was found that the lower aft part of the lift gate detent was worn. This created a ramping effect between the rounded edge of the lift gate and the flight idle stop. A worn lift gate detent would allow the power lever to inadvertently be moved into the beta range, causing asymmetrical drag and degraded airplane performance, particularly in critical phases of flight. All three occupants were killed.
Probable cause:
Occurrence #1: loss of engine power (total) - mech failure/malf
Phase of operation: takeoff - initial climb
Findings
1. 1 engine
2. (f) emergency procedure - simulated - pilot in command (cfi)
3. (c) throttle/power lever - worn
4. (c) propeller system/accessories, reversing system - deployed inadvertently

Circumstances:
The aircraft landed hard and short of the runway. The impact collapsed the right main landing gear and the aircraft was destroyed by the post crash fire. The pilot reported that on short final a muffled 'pop' was heard and the aircraft yawed to the right. Directional control was regained and the aircraft landed hard. Post accident inspection failed to disclose any pre-impact failure/malfunction of the aircraft or engines. Right engine propeller slash marks in the runway indicate power was being produced on the engine at touchdown. Both pilots were uninjured.

Circumstances:
Prior to the FAF during a VOR/DME approach, the Merlin was cleared to change to the unicom frequency. The pilot of the Merlin contacted unicom and requested and airport advisory. The unicom operator replied that there was a pirep of 500 feet over the field with two miles visibility but 'zilch' over the water. Shortly after this contact the pilot of the AA-5A called on unicom turning final. The pilot of the AA-5A was given the same advisory as given to the Merlin and further advised that another aircraft was inbound for runway 14. The aircraft collided less than one mile northwest of the approach end of runway 14. AIM 157 recommends that VFR inbound flights broadcasting entering downwind and final. AIM 363 recommends that, when making an IFR approach to an airport not served by a tower or FSS and after ATC advises to change to advisory frequency, to broadcast intentions, including type approach, position and when over FAF inbound. All three occupants in both airplanes were killed.
Probable cause:
Midair collision during IFR circling due to inadequate visual lookout on part of both crew. The following findings were reported:
- Unavailable control tower,
- Unavailable radar approach/departure,
- Low ceiling,
- Fog,
- Inadequate air/ground communications from both crew.

They were engaged in an illegal smuggling flight.
Probable cause:
Uncontrolled descent and subsequent crash after the pilot-in-command continued VFR flight into adverse weather conditions. The following contributing factors were reported:
- The pilot-in-command suffered a spatial disorientation,
- Thunderstorm activity,
- Aircraft came to rest in water,
- Aircraft loaded with marijuana,
- Severe thunderstorm in progress.
