Preliminary Reports

The airplane collided with up-sloping mountainous terrain at about 0822 Pacific time while maneuvering over the Joshua Tree National Park. The airplane was destroyed; the flight instructor and student were seriously injured. Instrument conditions existed in the vicinity.

The airplane ran off the side of Runway 23 at about 1521 Eastern time during the landing roll at the completion of a Part 135 on-demand air taxi flight. The pilot, co-pilot and passenger reported no injuries, but the airplane sustained substantial damage. Visual conditions prevailed.

At 1153 Eastern time, the airplane was substantially damaged when it impacted the Penobscot River. The solo commercial pilot was killed. Instrument conditions prevailed; an IFR flight plan was filed. The operator intended to ultimately deliver the airplane to a customer in Russia and additional fuel tanks were installed for the planned flight across the Atlantic Ocean.

At 1646 Central standard time, the airplane was substantially damaged during a runway excursion after landing. The private pilot was not injured. Visual conditions prevailed. The pilot later stated he applied the brakes to slow the airplane for a left turn off the runway after landing. Instead, the airplane began a turn to the right, which could not be corrected with left brake.

The pilot was landing a wheel-equipped airplane on a remote, snow-covered, seasonal airstrip. When the airplane touched down, the nose gear broke through the five-to-six inches of crusted snow on the runway and the airplane nosed over. The airplane sustained substantial damage to the vertical stabilizer and wings. The pilot reported no pre-accident mechanical failures or malfunctions with the airplane.

At about 1108 Eastern time, the airplane experienced a partial loss of engine power during climb shortly after takeoff. Visual conditions prevailed. The airplane was substantially damaged, but the commercial pilot and one passenger were not injured.

The airplane was destroyed when it impacted water and terrain at 1328 Central time while maneuvering to land at the end of the Part 91 positioning flight. The captain and first officer sustained fatal injuries. Visual conditions prevailed. Preliminary ATC and radar data revealed the flight was cleared for a visual approach to Runway 16, followed by a right traffic, circle-to-land approach to Runway 34.

The airplane experienced an in-flight loss of engine power, which resulted in a forced landing at 0747 Eastern time. The airline transport pilot was not injured and there was no damage to the airplane. Visual conditions prevailed. The aircraft was being operated under FAR Part 135 as an unscheduled cargo flight.

At 1845 Eastern time, the airplane collided with terrain following a loss of control and was destroyed. The airline transport pilot suffered fatal injuries. Visual conditions prevailed; an IFR flight plan was filed.

The pilot reported the airplane, which was equipped with long-range fuel tanks, had been fully fueled prior to takeoff. After 3.8 hours of flight, the engine began to surge, then lost power. An off-airport forced landing was made and the airplane nosed over. When the airplane was righted, the right fuel cap was missing, although the chain and spring clip were still in place.
