 AIR SRRVICR SECTION 



All Otter water dropping tanks ifere streamlined and modified from manually 

 operated dxunping to automatic* 



The streaiaLining of the tanks resulted in an increase of airspeed and 

 consequent inqsroved flying performance. 



The mechanical method of dunging was replaced by utilising a solenoid to 

 trip the latch on each tank* The pilot controlled the solenoid action by the use of a 

 push button located on the control wheel* 



A set of Beaver tanks was reversed to turn inwso^l instead of outward and 

 further tests will be conducted to evaluate the merits of this installation in combination 

 with streamlining and solenoid operated* 



Two Beaver aircraft were sold and the purchase of a new Otter aircraft 

 was concluded* * ' ■ . ' ^ '% 



A new shop was activated in o\ir Hangar to take care of Janitrol heating 

 unit overhaul and spark plug cleaning and testing* Additional equipment was added to 

 our Engine Overhaul Shop in order to greatly iBq>rove the detection of metal cracks and 

 defects*
