6/9/2015 - LANGLEY AIR FORCE BASE, Va., -- A
right wing control module failure led to an MQ-1B Predator crash on the
Nevada Test and Training Range near Creech Air Force Base, Nev., June
27, 2014, according to an Air Combat Command abbreviated accident
investigation board report released today.
The aircraft was assigned to the 432nd Wing, Creech AFB, and was under
the control of aircrew assigned to the 15th Reconnaissance Squadron,
also located at Creech AFB. At the time of the mishap, the aircraft was
conducting multiple training missions in the Nevada Test and Training
Range. The aircraft was destroyed on impact with losses valued at
approximately $4.6 million.
There were no injuries or damage to private property.
The board president found by clear and convincing evidence the cause of
the mishap was a right wing control module failure that lowered and
locked the right wing aileron, a flight-control surface on the trailing
edge of the wing which rolls and turns the aircraft, into a full-down
position. This un-commanded lowering of the aileron on only one wing
caused the MQ-1B to begin a roll and turn. This roll progressed until
the MQ-1B's steep angle of bank rendered it incapable of maintaining
level flight. The aircraft subsequently lost satellite communication and
continued to depart controlled flight until it impacted the ground.
