Certification

Certification plays an integral part of our design process. Australian microlights have to be strong enough to withstand more than normal flight loads. They have to withstand the flight loads plus a high safety factor. 6 G's represents 6 times the take off weight of the aircraft, this includes, the aircraft, pilot, passenger and fuel. The tests shown are to allow for a 450 kg max take-off weight for the XTS-912.

The XT is being certified to UK Section S under primary category. Primary category involves a high level of reporting back to CASA. We believe no other microlight as undergone certification to as high a level as primary category to date.

A successful lift. The wing has to completely clear the ground for more than 3 seconds and remain in tact. The Streak could have held the load for hour.

The bags are full of steel ball bearing in 5, 10 and 20kg lots. Velcro is used to stop the bags from sliding. For the positive lift the wing is lifted through the U bracket, where the wing normally attaches to the trike unit. A load cell is placed in lined to measures the load being lifted.

Engineers took measurements of the deflection in the trailing edge. This way they could be sure the load distribution represented in-flight loads as accurately as possible.

A heavy duty fork lift was used to lift the load through specially extended forks. Controlling the fork lift so it gave as smooth as possible lift was important. Even the smallest vibration at ultimate load could increase the load significantly through shock.

The weight is not just applied to the top surface. This picture shows how we apply the weight inside the double surface on the Streak. The undersurface is then Velcro'd back in place.

The trike base here is undergoing testing to show it complies to the 6G landing load tests. The loads are applied simultaneously to the engine mounts/mast, seat, fuel tank, front mast support and base tube.

The test rig was designed by Airbornes engineers and approved by the independent aeronautical engineer.

The bags full of steel ball bearings we used on the wings are also used for this test.

a series of pulley are used to apply the individual loads. Load cells are used to monitor the weight being applied.
