Owners and operators of single-engine turbine airplanes will have more inspection options under Part 91 beginning January 11, 2027. The FAA final rule, published November 10, gives them a choice. It does not require them to switch from the annual, 100-hour or progressive inspection provisions that apply to their operation.
What changes under Part 91
The pre-amendment text of 14 CFR 91.409 already lists manufacturer-recommended and FAA-approved owner or operator programs in paragraph (f). What changes is who may use those options: the amended paragraph (e)(2) explicitly lets single-engine turbine airplane owners and operators elect a paragraph (f) program.
The two options are distinct. One is a current inspection program recommended by the manufacturer. Another is a program established by the registered owner or operator and approved by the FAA for that aircraft.
What stays in place
Owners or operators who elect the alternative must identify the selected program in the aircraft’s maintenance records and follow it. Applicable replacement times for life-limited parts still apply. The rule changes the choice of inspection program, not the obligation to maintain the aircraft.
