easy307, you need to check the restrictions associated with your FI rating!
Restricted Privileges
Until the holder of a FI(A) rating has completed at least 100
hours flight instruction and, in addition, has supervised at
least 25 student solo flights, the privileges of the rating
are restricted.
The restriction will be removed from the rating when
the above requirements have been met and on the
recommendation of the supervising FI(A) (Please refer to
Section H1.4 – Removal of Supervisory Restriction).
Restrictions: The privileges are restricted to carrying out
under the supervision of FI(A) approved for this purpose:
a. Flight instruction for the issue of the JAR-FCL
PPL(A) or those parts of a CPL(A) or ATPL(A)
integrated course at PPL(A) level. Class and Type
ratings for single engine aeroplanes, excluding
approval of first solo flights by day or by night and
first solo navigation flights by day or by night; and
b. Night flying instruction, provided a night qualification
or rating is held, the ability to instruct at night has
been demonstrated to a FI(A) authorised to conduct
FI(A) training in accordance with JAR-FCL 1.330(f)
and the night currency requirement of JAR-FCL
1.026 is satisfied.
Also, the AIC to which you refer concerns an aircraft owned by the student, not the instructor!
