Paid 4,
The SIC Limitation topic has been beat to death on a couple of boards. And it has been a while since I messed with Citation Type ratings. So I did some research.
FAA Order 8700 – General Aviation Operations Inspector Handbook
CHAPTER 9. CONDUCT A PILOT TYPE RATING CERTIFICATION
7. SINGLE-PILOT CREWMEMBER. A pilot who applies for a type rating in an aircraft for which the pilot is required to hold a type rating as a single-pilot crewmember, must meet all applicable PTS criteria while satisfactorily demonstrating single pilot competency in that aircraft. This requires that the pilot demonstrate, without assistance, the required maneuvers and procedures during the practical test with the skill necessary for safe single-pilot operation.
A. Cessna 500-Series Aircraft. The holder of a CE-500 pilot type rating is entitled to act as pilot- in command (PIC) in Cessna models 500, 501, 550, 551, S550, and 560. However, Cessna models 500, 550, S550, and 560 require the use of an SIC.
(1) The successful completion of a certification practical test in any of the Cessna 500 models listed in paragraph 7A of this section will qualify the applicant for a CE-500 pilot type rating.
(2) An airman who obtains a pilot type rating as a single-pilot crewmember in models 501 and 551 may also operate models 500, 550, S550, and 560 as a member of a two-person crew.
(3) A model 501 or 551 certification practical test may be used to satisfy the requirements of a § 61.58 PIC proficiency check for any Cessna 500 model requiring an SIC.
B. Limitation. The limitation "SECOND IN COMMAND REQUIRED" is NOT placed on the Temporary Airman Certificate issued to an airman who satisfactorily accomplishes a practical test in either the CE-501 or CE-551. This limitation is appropriate only to the operation of Special Federal Aviation Regulation (SFAR) 41 airplanes. The practical test in the 501 or 551 models must be accomplished as a single-pilot crewmember. (None of the Cessna 500-series aircraft are SFAR 41 airplanes.)
But, back to the original question. If the Type Data Certificate required two pilot crew members (in this case an SIC) you will be able to log the time you fly as SIC. If the Citation only requires one crew member (501 or 551) an SIC in not required so No, you cannot log SIC time in that aircraft (unless you are flying part 135 which does require an SIC under part 135).
The Insurance companies may have something to say about a SIC that has not gone through some formal training (FlightSafety) with 500 hours total time especially all non jet time.
The Citation is a great flying aircraft. Go for the experience if you can. Good Luck in your endeavor.
