Alaska

During arrival to pick up a medevac patient, the flight was cleared for an LDA-1 runway 08 approach via the Asort transition. Thus, the pilot should have continued southeast on J-541 toward the SSR vortac and intercepted the localizer (loc) at Asort; then track inbound on the loc (062°), using I-JDL frequency 109.9 MHz (frequency for loc and co-located DME). After Asort, minimum altitude was 6,500 feet to Dibol intersection, 5,100 feet to Lynns intersection and 3,400 feet to the faf at Barlo intersection. DME from I-JDL to the intersections was: 18.2, 13.5 and 8 miles. DME from SSR (south of loc track) to the intersections was 11.2, 12.7 and approximately 16 miles. Flight reported Asort inbound while descending thru approximately 9,500 feet. Last radio call was 30 seconds later while descending thru 8,200 feet, 14 miles west of Dibol. Approximately 4 miles west of Dibol, aircraft impacted mountain side at 3,500 feet msl. No preimpact mechanical malfunction was found. There was evidence that both nav's were tuned to 109.9 MHz, but DME control head was inadvertently left in 'hold' position (locking DME to SSR rather than I-JDLl) and crew began a premature descent. Juneau weather was in part: 600 feet scattered, 3,000 feet overcast, 7 miles visibility. Pilot-in-command was currently flying both Learjet and DHC-7. All four occupants, two pilots and two doctors, were killed.

The aircraft collided with terrain in a mountain pass at an elevation of 3,600 feet msl. The pilot obtained a weather briefing at 1329 gmt on 9/26/85 at which time Merrill Pass was forecast to be closed by 1100 adt due to deteriorating weather. The last radio communication with the aircraft was at 1803 gmt when contact was made with McGrath FSS. At this time the pilot made a pilot report stating the weather at Merrill Pass was marginal; 2 miles visibility with snow and occasional moderate turbulence. The wreckage was located on 9/29/85 and indicated the aircraft contacted the terrain in a relatively level attitude with considerable airspeed. All three occupants were killed.

During a night arrival, the flight was on an instrument approach to the Gulkana Airport when radio contact with the aircraft was lost. A search was initiated and the wreckage was found 7.4 miles north of the terminal VOR on the 330° radial. The inbound course for the VOR runway 14 approach was on the 315° radial. An on-scene exam revealed the aircraft was tracking inbound when it collided with trees, crashed and burned about 2.4 miles before reaching the final approach fix. Both engines were operating during impact and both had ingested considerable tree material. No preimpact mechanical failure was evident. The captain and 1st officer were currently responsible for flying both the Learjet and DHC-7 aircraft. This was the captain's 1st day of work after returning from a vacation trip to Hawaii (approximately 1-1/2 weeks). The 1st officer had an adequate period for crew rest prior to reporting for work; however, he had previously been working a varied schedule. The operator repeatedly shifted pilots from 14 cfr 135 rest/duty requirements to those of 14 cfr 121. All three occupants were killed.

The aircraft crashed on the side of a mountain at an elevation of 2,200 feet approximately 3 miles from its intended destination, a remote lake. Purpose of the flight was to discharge caribou hunters into an area where caribou were spotted early that day. The aircraft was destroyed by fire. Inspection of the wreckage failed to reveal a mechanical failure/malfunction. All four occupants were killed.

Airplane accelerated to V1 and struck through on sandy beach. The nose pitched up and the pilot lost directional control. The airplane struck adjacent bank caught fire. It was totally destroyed.

During an instrument approach, the aircraft's right engine lost power. The pilot moved the right fuel selector to the left main tank and began emergency procedures. Shortly after that, the aircraft broke out of the overcast and the aircrew saw the airport. However, the left engine also lost power. The captain noted the fuel pressure was dropping and elected to land on tundra beside a road. During the landing, the aircraft was substantially damaged. No fuel was found in the aircraft during an exam of the fuel system. The captain noted that the left fuel cap was missing after the accident, but he did not see any fuel stains on the wing.

The amphibious aircraft crashed as the pilot was landing on glassy water at the inlet of Nerka Lake. Subsequently, it sank and came to rest inverted in clear water on the bottom of wood river with the gear retracted and the flaps extended. Moderate rain was falling when the pilot was landing. All three occupants escaped with minor injuries.

According to the pilot-in-command, he was attempting to fly through a mountain saddle. As he turned towards the mountain and began his climb the weather deteriorated rapidly with ceilings zero, visibility zero and severe turbulence. The airplane struck the side of a 1,707 foot high mountain at the 1,590 foot level on a magnetic heading of 015°. The pilot-in-command stated that just prior to impact he could not see anything. Two passengers were killed while three other occupants were seriously injured.

Aircraft crashed during missed approach to temporary winter landing strip. Aircraft hit in steep nose down attitude. Marginal weather conditions prevailed, with icing reported. All four occupants were injured, both pilots seriously.

The pilot was attempting a 180° turn to reverse direction away from lowering clouds and snow showers when the right wing dug into the snow covered terrain. The pilot stated a virtual 'white out' condition existed at the time. The pilot was uninjured and the aircraft was damaged beyond repair.
