NTSB Narrative Summary Released at Completion of Accident
On November 15, 2004, at 1400 coordinated universal time, a Robinson R-22B, G-DERB, was substantially damaged during landing at Biggin Hill Airfield (EGKB), United Kingdom. The pilot and passenger were not injured.
According to the Air Accidents Investigation Branch (AAIB), the helicopter landed without incident. However, the pilot noticed a vibration after transitioning to a hover at EGKB.
A post flight inspection of the main rotor system revealed that a main rotor blade exhibited a crack, which extended chordwise from the trailing edge, through 75 percent of the chord. In addition, the teeter head was extremely stiff.
This investigation is under jurisdiction of the AAIB. Any further information pertaining to this accident may be obtained from:
