Overview
A helicopter conducting local sightseeing flights from a school parking lot experienced an accident during takeoff. The parking lot measured approximately 75 yards by 35 yards. Near a highway adjacent to the lot, a six-foot chain-link fence required clearance during each takeoff.
Sequence of Events
After boarding passengers, the pilot hovered momentarily to assess the load and decided to continue the takeoff. After clearing the fence and accelerating into translational lift, the aircraft settled and impacted the highway. The helicopter then rolled over, shattering the main rotor blades.
Load Considerations
The helicopter was found to be about 20 pounds above its alternate loading limit. The cabin doors had been removed prior to the flight.
Conclusion
The accident involved a helicopter operating above its alternate loading limit, with the aircraft impacting a highway after takeoff from a constrained area.
