Aircraft maintenance and annual inspections,
documented like the airplane depends on it.
Annuals · 100-hour inspections · pre-buy support · AOG service · prop balancing · weight certification
A Part 145 shop for the work owners cannot treat casually.
Roger Wilco Aviation Services provides aircraft maintenance from Chan Gurney Municipal Airport in Yankton, South Dakota. The shop supports general aviation, corporate, commercial, light sport, and experimental owners who need inspections, discrepancies, troubleshooting, and documentation handled in a controlled repair-station environment.
RWAS is not just a place to park the airplane during an annual. The value is in the process: careful discrepancy review, clear communication before costs run away, parts and records traceability, logbook entries that still make sense later, and the ability to coordinate airframe, avionics, NDT, and fabrication issues when a simple inspection turns into real aircraft work.
Repair-station maintenance is a quality system, not just a mechanic with a flashlight.
Inspections, discrepancies, and return-to-service work.
The right maintenance path depends on how the aircraft is operated, what the records show, what the manufacturer requires, and what the inspection finds. RWAS scopes each job around the aircraft rather than using the same checklist conversation for every owner.
Annual inspections
FAR 43 Appendix D inspection flow, discrepancy review, owner communication, and return-to-service documentation.
100-hour inspections
Inspection support for aircraft operated for hire where the 100-hour requirement applies.
Condition and pre-buy inspections
Records review, physical inspection, and findings that help owners make decisions before money changes hands.
AOG Go-Van service
Practical response for aircraft-on-ground situations when the issue and location make mobile support appropriate.
Propeller balancing and weight certification
Support for vibration issues, aircraft weighing, and documentation needs up to the shop capability limits.
The system catches what memory misses.
An individual mechanic can be excellent. A repair station adds something different: procedures, inspection authority, controlled records, tooling expectations, traceability, and a certificate holder accountable for the system. That difference matters when the work involves avionics, structural questions, NDT findings, major repairs, recurring inspections, or sale-driven pre-buy decisions.
RWAS operates under FAA Repair Station Certificate RWSR491E with limited airframe, instrument, radio, and NDT inspection/testing capability. That structure gives owners a maintenance path designed to produce work that is inspectable, documented, and usable at the next annual, the next sale, or the next squawk.
Send records early, not after the airplane is apart.
Good maintenance planning starts with context. For inspections, pre-buy work, troubleshooting, or AOG support, send the aircraft make and model, N-number, current location, tach and total time, last annual or inspection date, known squawks, logbook photos, AD/service-bulletin concerns, and any deadline that matters.
RWAS will tell you what can be scoped from records, what needs hands-on inspection, and where the project may need avionics, NDT, fabrication, or parts coordination before the aircraft can return to service.
