Circumstances:
Following a relative long mission, the crew made a short stop at Moscow-Sheremetyevo. The captain believed it was not necessary to add fuel for a short flight to Moscow-Bykovo despite the reserves were low. After takeoff, the crew encountered strong headwinds then the visibility dropped due to snow falls and low clouds. In such conditions, a direct approach was refused to the crew who should differ the landing procedure. Few minutes later, both engines failed due to fuel exhaustion. The crew completed a belly landing in an open field located about 3 km from Bykovo Airport. All five crew members escaped with minor injuries while the aircraft was damaged beyond repair.
Probable cause:
Double engine failure caused by a fuel exhaustion.

While approaching Madinah Airport in limited visibility due to marginal weather conditions, the aircraft went out of control, entered a near vertical descent and crashed on the slope of a mountain located few km from the airport. The aircraft disintegrated on impact and both pilots were killed.
Probable cause:
It was reported that both elevators were not found at the point of impact and were missing. It is believed that the loss of control was the consequence of the elevator detachment in flight.

Circumstances:
Aircraft had been repossessed and was being ferried from Grand Junction, CO, to Chicago, IL, with en route stop at Denver, CO. After takeoff from Denver, landing gear would not retract. Pilot made several attempts without success. He elected to return to Denver. Pilot said that on final approach the right engine began surging and the left engine would not increase power. Aircraft made hard landing on runway, breaking left wing. Investigation revealed both speed levers would not function because engine prop governors and underspeed fuel governor reset arms, splined onto underspeed fuel governor shafts, were positioned on opposite side of speed lever actuating arms. Landing gear functioned normally during swing tests. It was later learned that right main tire had blown on takeoff 3 days earlier and required repair. Maintenance personnel opened the landing gear circuit breakers to preclude inadvertent gear retraction. Pilot said he checked circuit breakers when gear failed to retract. Both occupants escaped uninjured.
Probable cause:
Occurrence #1: airframe/component/system failure/malfunction
Phase of operation: takeoff - initial climb
Findings
1. (f) electrical system,circuit breaker - not engaged
2. (f) maintenance - inadequate - company maintenance personnel

Circumstances:
N4877V arrived over Clarion County Airport at about 2100 hours, and commenced a visual approach for landing. Marginal visual weather conditions prevailed at the time of the accident. The flight was observed by another pilot waiting on the ground for the aircraft. This pilot reported that the aircraft was seen through a break in the clouds as it turned left, southwest, as if to establish a left downwind for runway 05. The aircraft was located in a wooded area southwest of the airport. An examination of the wreckage failed to indicate any malfunction or system failure. The aircraft impacted the ground in a nose low attitude and the wreckage was confined to an area indicative with a stall type accident. The pilot, sole on board, was killed.
Probable cause:
Occurrence #1: in flight encounter with weather
Phase of operation: approach - vfr pattern - base leg/base to final
Findings
1. (f) weather condition - clouds
2. (f) weather condition - snow
3. (f) light condition - dark night

Circumstances:
The aircraft crashed about nine miles short of the runway during an ILS approach to Warwick, RI in IMC weather. The aircraft had been cleared to descend from 13,000 to 3,000 feet. The aircraft crashed outside the outer marker. The copilot had reported the aircraft as inside the outer marker. The crew did not report any aircraft problems. The approach procedure requires that the flight cross the outer marker at 1,800 feet msl five miles from touchdown. Minimum weather is 200 feet ceiling and 1/2 mile visibility. Surface observation at time of the accident was 300 feet overcast with 1 1/2 mile visibility. Post accident exam of the wreckage failed to disclose any malfunctions or failures in the equipment. Both occupants were killed.

Captain / Total hours on type:

Circumstances:
The pilot, executing an ILS approach, observed a primary hydraulic pressure drop and declared his intent to land without the use of flaps, speed brakes, reversers or nose wheel steering. The aircraft ran off the end of the runway during landing, traveled approximately 1,300 feet and came to rest on a golf course after striking two vehicles and a chain link fence. Post accident investigation revealed 0.8 quarts of hydraulic fluid (skydrol) in the reservoir. Reservoir capacity is 1.28 u.s. gallon. The pilot stated he pumped the brakes on approach to build pressure in the emergency brake system. The pilot announced he had no braked after touchdown. The Jet Commander 1121 operator's manual cautions against this practice. A functional check of the thrust reversers by on-scene investigators produced two complete cycles of operation. Two persons located in a ground vehicle were injured during the overrun landing.
Probable cause:
Occurrence #1: overrun
Phase of operation: landing - roll
Findings
1. (f) hydraulic system, reservoir - low level
2. (f) brakes (normal) - not possible - other maintenance personnel
3. (c) brakes (emergency) - improper use of - pilot in command
4. (c) improper use of procedure - pilot in command
5. (c) reversers - not used - pilot in command
6. (f) aircraft preflight - not performed - pilot in command

Circumstances:
After completing a cargo flight from Tiksi to Borogon, the crew was returning to Tiksi on a ferry flight. There were no passengers and no cargo on board. After takeoff from Borogon, while climbing to a height of 8 meters at a speed of 120 km/h, the flaps retracted automatically from 30° to zero. The aircraft entered an uncontrolled descent, struck the snow covered ground and crashed 250 meters past the runway end. All three crew members escaped with minor injuries while the aircraft was damaged beyond repair.
Probable cause:
It was determined that the flaps retracted prematurely and accidentally following a short-circuit by the flaps button where electrical resistances were corroded by condensation.

Circumstances:
An intermittent fire in the left engine accessory section led to loss of fuel to the engine. The right engine ingested water and quit. The landing gear had been left pinned in the down position because of a malfunction reported on the previous flight. Neither propeller was feathered, but the resulting high rate of descent led to a forced landing before the left tank blew up and the wing burned off. The aircraft was destroyed by fire after all three occupants escaped without serious injury. The aircraft was being ferried to another facility for restoration.
Probable cause:
Occurrence #1: miscellaneous/other
Phase of operation: standing - pre-flight
Findings
1. (c) maintenance, inspection - inadequate - company maintenance personnel
2. (f) preflight planning/preparation - inadequate - pilot in command
