Mr. C.B. Probert,

Inspector of Accidents

Department of Industry and Commerce

Kildare Street

Dublin, Ireland.

Dear Sir,

This is with further reference to your letter dated July 31, 1954 regarding the accident to DC6B aircraft N-6531C on February 15, 1954.

Our review indicates that we have no further evidence in connection with this accident which would be of any material use in connect ion with your investigation. However, we would like to state that your tentative conclusion as to the second contributory factory seems to us to be questionable. The pilot in question had received his Type Rating for DC6B aircraft prior to the flight in question and could have served as Captain. However, he was serving as co-pilot for familiarization in accordance with the Company’s procedures before taking over as Captain in command. His transitional training was in full compliance with the Civil Air Regulations which govern the operation. Under the circumstances, you may find it appropriate to revise your tentative conclusion.

Very truly yours,

(Signed)

John C. Pine,

Assistant General Counsel.
