Excerpt from the Summary:

“ For unmanned aircraft, including unmanned aircraft operating under 14 CFR part 135 that are authorized to use the inspection rules in part 91, this proposal would enable the selection of either an inspection program recommended by the manufacturer or a program established by the registered owner or operator and approved by the Administrator. The FAA believes this change would enhance safety and would provide unmanned and single-engine turbine- powered aircraft owners and operators with greater flexibility with aircraft maintenance. Additionally, for aircraft operating under part 91, subpart K, fractional ownership rules, the FAA proposes to lengthen the reporting interval for aircraft mechanical reliability reports from 72 to 96 hours and to allow electronic report submissions. This would align the reporting interval requirement with those found in other regulations (e.g., 14 CFR 121.703, 135.415, and 145.221). Finally, the FAA proposes several changes to clarify and simplify various maintenance-related regulations in areas that have confusing or ambiguous.”
