O-line,
You are correct. 14 CFR 135.338(b) spells out the requirements for flight instructors under that part, and the only certificate requirements are the applicant holds certificates and ratings required to serve as PIC under 135 in the aircraft involved.
However, that instructor can give no required instruction for any certificate or rating, nor endorse for any certificate or rating, outside of those duties. For example, a commercially certificated pilot employed as a company instructor in the company Seneca II, can't go training one of the company mechanics for an isntrument rating in the Seneca...even though that pilot can provide instrument instruction prepatory to a Part 135 checkride for a company pilot. In order to provide the instrument training for that mechanic, the pilot would have to hold an instructor certificate with instrument airplane privileges.
To return to topic with the the thread, pursuant to the above paragraph, an ATP providing instruction to other pilots in that company, also cannot provide the instrument instruction to the mechanic toward his instrument rating.
