THIS SERVES AS A MAJOR DISTR TO THE IMPORTANT ELEMENTS OF SAFETY. OUR ACFT; A CESSNA (RECENTLY ACQUIRED); WAS RETURNING FROM A CHARTER FLT TO MONTREAL; CANADA; CLRING CUSTOMS IN PORTLAND; ME. THE ACFT RECORDS CHK REVEALED THE REGISTRATION TO BE THE 'PINK SLIP' COPY OF THE APPLICATION PAPERS. GOOD FOR 'FLT WITHIN THE UNITED STATES.' ALTHOUGH NOT YET RECEIVED; A FLT TIME WIRE TEMPORARY CERTIFICATE HAD BEEN REQUESTED AND PROMISED FROM THE FAA PRIORITY DESK AT OKC ON DEC/TUE/94.
