A STUDENT PILOT LOST CONTROL OF HIS HOMEBUILT GYROPLANE ON ITS MAIDEN FLIGHT. DUE TO THE LOW CEILINGS AND HIGH WINDS, THE PILOT ELECTED TO RESTRICT HIS MORNING TRAINING SESSION TO GROUND RUNS AND SHORT HOPS OVER THE RUNWAY. DURING THE FIFTH LOW FLIGHT, THE GYROPLANE WAS OBSERVED HIGHER OVER THE GROUND THAN ON ANY OF HIS PREVIOUS RUNS, AND AS THE AIRCRAFT APPROACHED THE END OF THE RUNWAY, FULL POWER WAS HEARD BEING APPLIED AND A STEEP CLIMB ESTABLISHED. WITNESSES REPORTED THAT AFTER TURNING DOWNWIND, WHILE STILL OPERATING AT FULL TAKEOFF POWER, A PROGRESSIVE PORPOISING LIKE OSCILLATION DEVELOPED FOLLOWED BY A LOSS OF CONTROL. THE GYROPLANE WAS OBSERVED DESCENDING RAPIDLY TUMBLING END OVER END UNTIL IT DISAPPEARED BEHIND A TREE LINE. THE TRIM SPRING USED TO PROVIDE SENSITIVITY AND STABILITY TO THE ROTOR SYSTEM WAS FOUND OUT OF ADJUSTMENT
Probable Cause: THE PILOT'S INADVERTENT PORPOISE. A FACTOR WAS THE IMPROPERLY ADJUSTED TRIM SPRING
