If you are a current certified flight instructor (CFI), you may train sport pilot candidates, within the category/class listed on the on your CFI certificate. Obviously, you will need to become familiar with the sport pilot rules under 61 subpart J. The book, SPORT PILOT & CFI APPLICANT CHECKRIDE will fill you in on everything you need to know.
If you are a current airplane CFI under subpart H and you want to instruct in a Powered Parachute (PPC) light-sport aircraft (LSA), the first step is to recieve a proficiency check to add the Powered Parachute (PPC) Sport Pilot rating. Once you obtain the pilot rating then you can add the instructor privileges.
Note that both the sport pilot Powered Parachute (PPC) pilot and Powered Parachute (PPC) CFI is a privilege and not an additional rating; as such you will not have to pass a checkride with an examiner but a proficiency check with a Powered Parachute (PPC) CFI as described below. It is possible to add a Private pilot PPC rating but this requires 40 hours PPC total (similar to an airplane) additional time. See Private Pilot PPC for details for obtaining this additional PPC Private Pilot rating.
If you are a current airplane CFI who wishes to instruct in Powered Parachute (PPC) yet is not currently rated in Powered Parachute (PPC), you must add the privilege at the sport pilot instructor level by proficiency check in accordance with FAR 61.419 as described below.
(a) Receive a logbook endorsement from the recommending authorized Powered Parachute (PPC) instructor (CFIS #1) who trained you on the applicable areas of operation certifying you have met the aeronautical knowledge and flight proficiency requirements for the Powered Parachute (PPC) category and class flight instructor privilege you seek;
(b) Complete an application for those privileges and obtain a recomendation for the instructor who trained you (CFIS#1) on a form and in a manner acceptable to the FAA (8710-11 form) and present this application to a seperate authorized Powered Parachute (PPC) instructor (CFIS#2) to conduct the proficiency check;
(b) Successfully complete a proficiency check from the seperate authorized instructor (CFIS#2) other than the recommendating instructor who trained you for the Powered Parachute (PPC) category and class flight instructor privilege you seek;
(d) Receive a logbook endorsement from the instructor who conducted the proficiency check certifying you are proficient in the areas of operation and authorized for the Powered Parachute (PPC) category and class flight instructor privilege.
