Information contained in the approved flight manual and pilot's operating handbook was not applicable to the engine that was fitted to the aircraft.
Association has written an Operations Bulletin on Flight Manual Supplements
The aircraft owner’s association has updated a previously-written article on this risk and the article on Flight Manual Supplements has been placed on the Airtourer Association website. The article was also published in the association’s November Newsletter.
The association has also drafted an Operations Bulletin advising certificate of registration holders and pilots of the possibility of AFM data being amended by a supplement. That document is currently undergoing the association’s document review process. The association also intends to hold an 'AFM [Approved Flight Manual] Workshop' at one of their upcoming aircraft ‘fly-ins’ to provide registered owners with the knowledge to allow them to assess their own aircraft’s AFMs for all required supplements.
The ATSB is satisfied that the action being taken by the aircraft owner’s association will, when complete, adequately address the safety issue.
