 left off. ^ 



Damage to Aircraft: 



I regret I have to report three mishaps during the year involving the loss 

 of three machines, but no loss of life or severe injury to personnel. The motors 

 and all equipment were salvaged from two of these machines, which greatly 

 reduced the loss. 



In July machine Owl, a Loening Air Yacht, was crashed at Sudbury by a 

 pilot having no experience with the operation of such type, a monoplane, and 

 operating in disobedience to Provincial Air Service orders and Air Regulations 

 1920. The pilot in question, after a Court of Enquiry by the officials of the 

 Department of National Defence, had his license suspended for a period of six 

 months. Slight injuries were suflfered by the pilot and his unauthorized pas- 

 sengers. 



In August machine Eagle, proceeding to the assistance of machine Falcon 

 in the Red Lake area, landed with necessary spare parts and in manoeuvring 

 to take off for the return to Pine Ridge struck a large submerged rock. The 

 hull was so critically injured that, after a careful survey of the entire situation, 

 it was decided that the expense in connection with salvage would be greater 

 than the purchase price of a new machine of this type. The engine and all 

 parts, including rigging fittings, were salvaged and returned to the operating 

 base at Sioux Lookout. 



Machine Buzzard, returning to Sault Ste. Marie after the completion of 

 the season's operations and when actually in sight of the city, was forced to 

 land on Lake Superior, due to the fact that water condensation in the gravity 

 tank made a mixture that did not function correctly in the Liberty engine.
