As I worked my way up from the King Country to the Waikato on a Thursday afternoon there were a few original homebuilt aircraft from the AACA era on offer:
At Te Kuiti was Gary Williams' Jodel D 11 ZK-KSD (c/n AACA/430). It was originally built by Gary and first registered in April 2004. It could be parked up at Te Kuiti to give room for the RV 8 that Gary Williams is building at Otorohanga
Hangared at Hamilton Aero Maintenance at Hamilton Airport was Dave Stewart's Squirecraft SA 102.5 Cavalier ZK-DJS (c/n AACA/250). This was built by Dave and was first registered in February 1984. I was told that it hasn't flown for a couple of years but it still looks in great condition.
And a bit further North at Te Kowhai Zenith CH 200 ZK-ZEN (c/n AACA/662) was taxying back to its hangar after doing circuits. This aircraft was built by Barry Vivian at New Plymouth and was first registered in November 1983.
