NTSB Accident Report

On July 10, 2011, about 0910 eastern daylight time, a Robinson R22 BETA, N10786, operated by Ocean Helicopters Inc., was substantially damaged during an autorotation, following a system malfunction during initial climb from Palm Beach International Airport (PBI), West Palm Beach, Florida. The certified flight instructor (CFI) was not injured and the student pilot incurred minor injuries. The instructional flight was conducted under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed and no flight plan was filed for the planned local flight, which departed PBI about 0840. According to the CFI, he and the student pilot performed five or six quick-stops. They then proceeded with a normal takeoff. About 200 feet above the ground, the helicopter yawed right, which was unable to be corrected with left pedal input. The CFI then entered an autorotation as the helicopter continued to yaw right. He also observed that the horizontal and vertical stabilizers had separated from the tailboom and were falling to the ground. According to a Federal Aviation Administration inspector, a fuel cap separated and lodged in the tail rotor system, resulting in a loss of tail rotor thrust. The helicopter subsequently spun during the autorotation and landed hard. During the impact, the tail rotor separated and the fuselage sustained substantial damage.

The fuel cap was not completely screwed on to the fuel tank, resulting in it falling off in flight and striking the tail rotor. This is easily preventable, but not so easily recoverable. So, make sure that not only both fuel caps are on the helicopter but that their torque stripes are lined up with the fuel tank.
