Well, just tried getting an SIC type rating added at the Boston FSDO, unfortunately, unsuccessfully.
It seems that it is possible, but my application was shot down on several points-- no signature on the back of Form 8710 in the part of instructor recommendation (I guess I misread the guidance form). Also the inspector had issues with the authenticity of the signature (no title given as to who signed the endorsement), and whether the rubber stamp was added with the signature or whether it was always there on all records. Furthermore, I had handwritten the preamble endorsement in blue ink, and our chief training captain had signed it in black ink-- the inspector claimed I
could have possibly added the endorsement after the signature (from whoever it was from) was already on the paper.
Oh well, I guess I´ll have to try again on the next trip to the US.
P.S. Yes Ernest, we are only talking about SIC Type Ratings-- for command ones you have to jump through the US checkride hoops.
