Rather a grey day to start with, and not a good weather forecast. We had planned that John Trezise would fly the Grob Twin 11 today and he had been studying the flight manual. He noticed that there is a requirement to do a 100 hourly inspection on it - a thing that everyone else in the club including me had missed so far. The 100 hourly inspection was due so we didn't fly it.
John flew the Puchatek instead, solo, and managed two soaring flights, and one straight up and down. There were cumulus about under the overcast, and eventually some blue sky. The rain showers bypassed Lake Keepit, but seemed to sit over Mt Borah.
Now that John has done his five flights needed for his A certificate, he decided to help us to do the maintenance on the Grob. The first necessity was to fix the wheel brake. Boris is now an expert on aircraft brakes, and he was able to pressure bleed it from the bottom. We managed to get some brake, but not enough. Further attempts proved impossible as the oil can we were using fell apart. Looks like more glider maintenance tomorrow.
