Just found this thread, having temporarily relocated to Adelaide. As one of the retired Baby Boomers I can assure you that I don't intend to "pop my clogs", nor do I have the inclination to buy a "GA wannabe". What does concern me is that there will ALWAYS be the current pathway for those who choose to build and maintain their own aircraft, including engines other than Jab or Rot; that is the 19 category. Already (if I correctly interpret the constantly changing rules) it is now not possible for the purchaser of a pre-owned 19 aircraft to conduct their own maintenance, regardless of how much experience that they can demonstrate, including having perhaps having previously built 19 aircraft themselves. I totally agree that in order to maintain your own aircraft there must be some assessment and accreditation of skills, but this must also take on board the homebuilts.
As to getting young people on board - we are trying! During the past 10 years I have been teaching the engineering component of the Aviation Program at Mid North Christian College in Pt. Pirie, SA. This program also teaches all BAK, Nav, HF and Meteorology to Pilot Certificate level and also provides flight training through Spencer Gulf Flight Training. The program aims to provide a wide background knowledge of hands-on aviation rather than attempt to provide industry qualifications. Students gain accreditation in the SACE (Sth Aust Cert of Ed). Over the years many of our students have gained positions in RAAF , gone on to CPL, started their path to LAME or simply continued to fly recreationally. The continued success of this program suggests that it is a viable way to introduce school students to flying.
