Murphy's Law Saturday

26-Sep-15

      
With the weather forecast on Thursday night suggesting wet weather through to Sunday and a sunny Monday followed by about a week of rain, it was surprising to read that CGC had such a big day yesterday ... and an even bigger surprise to see a "soarable-looking" shy above Caboolture at around 9.00 am this morning.      
     
The Duty Crew of David Higgs (Duty Instructor), Tony Esler (Tug Pilot), Kevin Rodda (AEI) and Alan Graham (Duty Pilot) had no trainees or other members to arrange flights for but the chance of one Air Experience passenger at 11.00 am (doubtful and unconfirmed due to the weather outlook).         
 
Murphy's law was in full swing (anything that can go wrong will go wrong). The plan was for Alan to do his annual flight review in the IS-30 (long legs and the Blanik are not the best of combinations). David and Alan barely had the IS-130 ready to go when they took a phone call from Rod Wilson ... you guessed it, Rod wanted to fly a friend in the Blanik! The Blanik was then made ready to go.
 
Alan then detected (when putting the dolly on the IS-30 to tow it out) that its tail wheel was rubbing against its housing and was therefore not turning as easily as it should be!     
    
David, Alan and Tony headed to RWY12 with the Blanik (GYK) and the tug (SPA) while I stayed back at the tie-down area to remove the tail wheel on the IS-30 to investigate the problem. 
   
Things improved rapidly however when I was able to address the problem by deflating the tyre, remove the wheel, reposition the tyre on the wheel hub, re-inflate the tyre (with less pressure) and then re-fit the wheel to GQA. 

Even more luck came our way when, with impeccable timing, Speedy (Bernie Gonsalves) dropped in to the airfield to pick up some materials for some work that he was doing at home. A valuable and much appreciated second opinion to confirm my assessment that the wheel and tyre were now OK for use but need to be replaced soon for optimum ongoing operation.    

           

Rod Wilson and friend Campbell McClennan.

     
By the time of our first launch at 11:07, the sky looked quite inviting ... but with a strong wind coming in from the south-east, it looked like there would be only a one or two hour window of opportunity before the clouds drifted away to the north-west.

The result was only four flights (with two fights in each glider) and both gliders landed back on RW06 to end the day's operations by 12:30 ... 

Rod Wilson with friend Campbell McLennan in GYK (15 mins from 3000ft), Alan Graham's Annual Flight Review in GQA with David Higgs (15 mins from 3500ft), Kevin Rodda solo in GYK (24 minutes from 3400ft) and David Higgs solo in GQA (20 mins from 3500ft). 

There were some bumps of thermal activity, however it was difficult to get even a full circle of lift.

From then on, the weather deteriorated rapidly. As I left the airfield at around 2:30 the windsock was still straight down 12 and the clouds downwind to the north-west were starting to look more threatening ...   
   

 

 

... and looking back along RWY06 from the gate, rain was starting to fall on the hills to the west of Caboolture ... 
     

 

 

Fifteen minutes down the highway towards Brisbane it was raining ...   
    

 

The rain had cleared before North Lakes ... but as I headed in to Brisbane over the Pine River Bridge, storm clouds were again the feature of the western shy.
