But it does require:
(1) In addition to those persons listed in paragraph 3a, § 43.3(g), (h), and (i) authorize the holder of a pilot certificate issued under part 61 to perform preventive maintenance. Section 43.7 limits the privilege to persons holding at least a private or sport pilot certificate and § 91.407(a)(1) prohibits operation of the aircraft unless approved for return to service. Further, pilots may only approve for return to service preventive maintenance which they themselves have accomplished.
No private certificate, no authorization to return to service.
