Maintenance Assistance

for RAAus Sport's Aircraft

Most technical or legal matters involving RAAus Light Sport Aircraft (LSA) are now considered (by RAAus) to be resolved through an existence of, or creation of a direct relationship between the owner and the manufacturer.  RAAus no longer notify manufacturers of aircraft ownership transfers. So BEWARE!

The owner is responsible for the safety of their aircraft.

Ballistic Parachute Systems

Most BRS systems require a replacement rocket after 10 or 12 years.   

We asked   "What should RAAus members do with TIME EXPIRED rockets?"

1st answer :  "We first recommend contacting local authorities to see if they will assist with the disposal."

Foxbat A22LS Throttle Travel

At least one aircraft  is affected and possibly there are others.  The issue we found is that the cockpit throttle lever meets the fixed end stop before the carburetor levers have reached full (power) travel. As such, if idle is set correctly, then full travel is not available at the carburetor levers and the carburetors cannot be set IAW the Rotax maintenance manual.  At least one aircraft has had the throttle lever modified by filing the notch larger to allow full travel, but of course this would have been a non-compliant modification to the LSA aircraft. 

Advice from Flight Safety Solutions

If you see another instance of this issue, we suggest you report the matter via the RAAus OMS.


"They exited the aircraft to find oil sprayed all over the left hand side of it, from the nose wheel the whole way along the belly and main wheels to the elevator.

The cowling was removed to see where the oil was coming from. At first it was not clear as there was a lot of oil spread around.

The pilot then rang the maintainer to tell them the plane was covered in oil, the burning smell and that the oil pressure dropped during the flight. The maintainer advised the pilot to return so they could look what was wrong. During the call the oil was found to be coming out of the rocker oil tube. The pilot told the maintainer that the rocker oil tube is visibly loose and oil was definitely coming out of it.

The maintainer then replied that they forgot to do up the rocker oil tube. They then instructed the pilot how to do up the rocker oil tube, replace the oil. (they had 2x w100 piston engine oil bottles with them). After the pilot did this and cleaned the oil off the aircraft they completed a successful engine run up on the ground. They then flew directly back."
