Airworthiness:
Heavy Models and Turbines

Models weighing between 7 kg and 25 kg are defined as heavy models and these require a heavy model permit to fly. Permits can only be granted after an Airworthiness Inspection and evaluation process. This includes demonstrating to a MAAA Heavy Model Inspector that the person to be authorized to fly the model has the ability to safely operate the model in flight.

​

These permits are valid for three years and are issued to the owner or other nominated pilot (for independent operation). If sold before expiry of the three years a new permit is required.

​

Modellers who are planning to build a Heavy Model should contact their nearest available MAAA Inspector to discuss any technical aspects and arrange a mutually acceptable location for the inspection & evaluation flight. The form can be found here.

Details of the permit requirements are given in the MAAA Manual of Procedure’s which can be viewed on this site. 

​

Models weighing between 25 kg and 150 kg are defined as giant models and as such require a giant model permit to fly. Giant Model Permits can only be granted after an Airworthiness Inspection and evaluation process carried out by a Giant Model Inspector.

Gas Turbine and Pulse Jet Inspections

Gas Turbines or Pulse Jets are treated in the same way as above, but different paperwork is required. Weight limits between 7-25kg do not apply, ALL gas turbines or pulse jets require a permit to fly. There is a Manual of Procedure covering these which can be found on this site. Any of these types of models that way over 25kg will require further inspection by a Giant Model Inspector with a Gas Turbine or Pulse Jet Endorsement, as the case requires.
