I had my 737 type rated friend give the training for a my 737 SIC. We just made logbook entries showing we covered what was required. Funny thing was the inspector at the FSDO was completely lost and I had to explain the process to him. He asked another inspector who told him explained the process. In the end his comment was "I`ll send it in if they don`t like it they`ll kick it back". Went through no problems. The SIC is only needed for travel outside the USA. It`s actually not clear if one T/O and Landing is required.
