Descripción:
The aircraft, a Cessna 208B Grand Caravan (Blackhawk VY conversion), Trans Guyana Airways Flight 700, on a shuttle operation between Olive Creek and Imbaimadai airstrip, impacted wooded terrain in the Mazaruni area. The airplane was destroyed. The pilot and cargo handler suffered fatal injuries. The aircraft took off from Olive Creek at 10:54, carrying fuel and other supplies for gold mining operations.
Two and a half minutes after takeoff the engine lost power. The aircraft lost height and impacted an undulating and heavily forested area. Since only three of the seven oil drums were secured, the remaining four shifted forward during the crash.
In June 2013 the aircraft received a Blackhawk modification, which consisted among others of the installation of a factory new P&W PT6A-42A engine.
CONCLUSIONS: The investigation revealed that the probable cause of the accident was due to a power loss suffered by the engine. The power loss was associated with the fracture of one of the 1st stage compressor stator vanes by fatigue. The fatigue crack originated from a lack of brazing adhesion extending over approximately 0.280 inches along the chord length and 0.050 inches in the direction of the shroud thickness and was located between the leading edge and mid-chord of the vane.
