Circumstances:
On a night approach to Nouadhibou Airport, the crew encountered limited visibility. When the aircraft reached the decision height of 300 feet on final, a missed approach procedure was initiated when the captain thought he had a visual contact with the runway. He decided to continue the approach when the airplane contacted water and crashed into the sea less than one km short of runway threshold. A passenger was killed while 18 others were injured. The airplane was destroyed,
Probable cause:
Controlled flight into terrain (water) after the crew continued the approach after passing the decision height in marginal and limited visibility.

Circumstances:
The aircraft crashed while making a visual approach to runway 27R at Philadelphia International Airport. The aircraft, a scheduled commuter flight from Reading, Pennsylvania, arrived in the Philadelphia Approach Control area as a VFR 'pop up' flight and was sequenced to land behind United flight 555, a Boeing 727 IFR arrival, on runway 27R. Witnesses stated that, when flight 501 was about 1/2 mile on final approach, it rolled from side to side, pitched up, rolled inverted to the left, and flew into the ground nose first. All three persons aboard the aircraft were killed and the aircraft was destroyed.
Probable cause:
The probable cause of the accident was the loss of aircraft control due to an encounter with wake turbulence from the preceding aircraft at an altitude too low for recovery and the pilot's failure to follow established separation and flight path selection procedures for wake turbulence avoidance.

Circumstances:
At 1702, Scenic Airlines flight 306, a Cessna 404, VFR commuter flight to Phoenix, crashed approximately three miles south of runway 21 after takeoff from the Grand Canyon National Park Airport. The aircraft cut a swath through a densely wooded area on a magnetic heading of 165° and came to rest upright about 230 feet from the initial point of impact with trees. Impact forces and an intense fire destroyed the aircraft. The pilot and six of the seven passengers were killed in the accident. One passenger survived the accident but died five days later as a result of thermal injuries.
Probable cause:
The probable cause of the accident was a substantial loss of power from the left engine at a critical point in the takeoff an the failure of the pilot to establish a minimum drag configuration which degraded the marginal single-engine climb performance of the aircraft. The loss of power resulted from the seizure of the turbocharger following a progressive failure of the turbine wheel blades initiated by foreign object ingestion which had occurred previous to this flight and was not detected during maintenance on the engine 4 days before the accident.
