Aircraft Modifications


The table below is for the use of regulatory bodies and inspectors and forms Annex B of the TADS or TCDS.


The table  shows all approved minor modifications to date together with the aircraft type applicability.  Those modifications fitted to a particular aircraft are detailed on its Statement of Aircraft Conformity (SAC) at release-to-service.


Most modifications are improvements to production processes and may not be suitable for retro-fit to after-market aircraft.  Those which are will be listed under a Service Bulletin on the aircraft owners’ page.  Owners should note that only approved modifications should be fitted to an aircraft.  Unapproved mods invalidate the Permit to fly/C of A and insurance.
