Rotorcraft Maintenance Log

Rotorcraft maintenance is rhythm-based: vibration drives track-and-balance events, dynamic components carry retirement lives, and 100-hour cycles arrive monthly at tour utilisation. Those particulars define the record worth keeping: track-and-balance runs, dynamic component changes and hour-based repetitive inspections dominate the record. A log structured around them (rather than a generic 'date/work' diary) means the patterns and recurring obligations of THIS kind of operation stay visible — which is most of what separates well-maintained examples from the other kind.

Preventive maintenance per Part 43 Appendix A may be owner-performed on Part 91 aircraft (with proper record entries); everything else needs appropriately certificated personnel, with inspections signed by the holders the rule specifies. The 'performed by' field in this log keeps the authority question answerable for every entry — exactly what a records review checks.
