Experimental aircraft support
Support may include records review, maintenance planning, Rotax or propeller context review, and owner coordination where the aircraft documents and applicable privileges support the requested scope.
Rotax 9 Series
Rotax 9 Series Support — 912, 914, 915 iS & 916 iS
Lima Charlie Aero LLC supports Rotax 912, Rotax 912 ULS / 912ULS, Rotax 912 iS, Rotax 914, Rotax 915 iS, and Rotax 916 iS owners with a documentation-driven process based at KAKH / Gastonia Municipal Airport, serving Charlotte NC and the Carolinas by appointment.
Common Owner Problems
Start with what changed on the aircraft.
Symptoms are data points, not conclusions. The useful next step depends on aircraft identity, location, engine family, installation context, records, and the specific condition the owner is seeing.
Ignition, ECU, and electrical faultsRough running, hard starts, excessive ignition drop, ECU/EMS warnings, sensor faults, wiring, grounds, and charging issues.
Fuel delivery, carb, injector, and vapor issuesFuel pressure changes, carb balance concerns, float issues, injectors, vapor symptoms, contamination, and uneven running.
Rubber aging and fluid leaksFuel hoses, coolant hoses, oil hoses, sockets, seals, leaks, routing, age, and logbook support.
Cooling, oil, and temperature managementHigh oil temperature, high CHT, coolant temperature, coolant loss, oil pressure, airflow, and operating data.
Gearbox, propeller, and vibration concernsGearbox chatter, friction torque context, propeller vibration support, prop balancing support or coordination, kickback, and shock-loading history.
Turbo / EMS support for 915 iS and 916 iSTurbocharger, intercooler, exhaust, fuel pressure, sensors, engine management warnings, and installation context.
What To Send First
Aircraft, location, symptom, and recent context.
A useful first request does not need to be a maintenance worksheet. Send the N-number or tail number, aircraft location, engine model if known, what changed, when it happens, and any recent maintenance or clear fault message.
If the issue points toward records, photos, operating data, propeller details, airfield tools, or manufacturer coordination, those details can be requested after intake.

Focused System Review
The engine is reviewed as part of the aircraft system.
A reported value, a verified value, and a maintenance conclusion are not the same thing. Fuel, induction, cooling, oil, electrical, propeller, gearbox, records, and installation details can all affect the next step.
No support activity is controlled until aircraft, location, symptom, and next action are captured. The goal is not to guess faster; the goal is to move from uncertainty to a controlled next step.
912 / 914 / 915 iS / 916 iS Detail
Support is organized by engine family and symptom.
Rotax support Charlotte NC and Rotax service Carolinas requests often begin with a single issue: excessive mag drop, rough idle, carb sync concerns, high oil temperature, fuel pressure warnings, rubber replacement timing, gearbox/propeller vibration, or EMS messages. Lima Charlie Aero LLC keeps those clues organized before work scope is discussed.
Work scope depends on documents, records, configuration, symptom, applicable instructions, tooling, parts, location, and certificate privileges.

Rotax 912 carb balanceRough idle, vibration, throttle/choke cable condition, intake leaks, carb sync history, and fuel condition.
Rotax 912 high oil temperatureOil temperature, coolant behavior, airflow, pressure readings, installation details, and operating context.

Beyond Engine-Only Troubleshooting
Some Rotax calls need more than an engine-only answer.
Light-sport aircraft support Charlotte, SLSA / ELSA support, experimental aircraft support, e-Prop coordination, aircraft records review, and light-sport prebuy questions are handled with the same documentation-first discipline.
Propeller / vibration support
Propeller vibration support can include propeller and gearbox interaction review, prop balancing support or coordination, manufacturer documentation review, and operating-condition intake.
Manufacturer coordination
LOA-related documentation support, manufacturer coordination, engineering packet support or coordination, e-Prop coordination, and cracked engine cage documentation support are organized without implying approval authority.
Flight school / fleet support
Flight school Rotax support may include repeat squawk tracking, records review, scheduling coordination, and support planning for Rotax-powered training aircraft by appointment.
Training / Credential Context
Credentials support the process; aircraft documents control the work.
RFSC / Rotax iRMT-listed training credentials include 9 Series Service, 9 Series Maintenance, and 912 iS Installation. The listing can be verified here.
Credentials do not replace aircraft-specific maintenance manuals, operating limitations, service bulletins, safety directives, required records, or the certificate/rating privileges needed for a specific task.
What to send first
N-number if known, aircraft location, engine model, short symptom description, recent maintenance if known, and any clear fault messages or operating conditions.
Support Request
Capture the aircraft, then define the next controlled step.
First contact only needs the basics. If records, photos, fault messages, airfield tool details, or manufacturer coordination are needed, those can be requested after the aircraft, location, and symptom are captured.
Receive symptoms
Aircraft, location, engine model, and what changed.
Request records if needed
Logs, photos, fault messages, service history, propeller details, or installation context.
Define scope
KAKH, mobile feasibility, records review, troubleshooting, inspection support, or manufacturer coordination.
Start clean
Send the support request when the aircraft, location, and symptom are ready.
