Aircraft Magneto Testing
Regular testing ensures magnetos function correctly:
A) Spark Testing: Verifies the magneto produces a strong spark.aircraftmag
B) Timing Checks: Ensures the magneto fires at the correct engine position.
C) P-lead Continuity: Confirms the grounding circuit operates properly.
Aircraft Magneto Troubleshooting
When experiencing engine performance issues, it's essential to determine if the magneto is the source. A "bad mag check" during pre-flight run-up can indicate potential magneto problems. Common symptoms include:
-
No RPM drop: This could suggest a broken P-lead. To test, bring the engine to idle and switch the ignition to "Off." If the engine continues running, the P-lead may be faulty
-
Excessive RPM drop: This might indicate issues like a fouled spark plug, improper magneto timing, or internal magneto faults.
Magneto problems in aircraft can cause a range of engine performance issues, including rough running, misfires, reduced power, or difficulty starting. Common causes include worn points, weak coils, faulty ignition leads, fouled spark plugs.
Troubleshooting involves systematically checking for consistent ignition output, verifying proper timing, and inspecting components like the distributor block, breaker points, and internal wiring.
MAGNETOS SERVICE
500-hour magneto inspection: As recommended magnetos should undergo inspection every 500 hours of operation.
Why You Should NEVER Skip the 500 Hour Magneto Inspection
-
🛠 Prevent In-Flight Failures
-
Magnetos can wear internally or develop carbon tracking, cracked distributor blocks, or corroded bearings. These issues can lead to misfires or complete ignition failure.
-
-
⏱ Catch Hidden Wear Early
-
Even if your engine sounds fine, internal components like gears, contact points, or impulse couplings may be near failure. The 500-hour inspection uncovers wear long before it becomes dangerous or expensive.
-
-
🛠 Airworthiness Compliance
-
Following manufacturer guidelines and FAA recommendations isn’t optional it’s part of staying compliant with airworthiness standards and avoiding potential grounding during ramp checks or inspections.
-
-
🛠 Optimize Engine Performance
-
Dirty, worn, or misaligned components can cause poor spark timing, leading to rough running, loss of power, higher fuel consumption, and difficult starts, especially in cold weather.
-
-
💸 Avoid Costly Repairs
-
A skipped inspection may save a little now, but it can lead to expensive overhauls or emergency repairs later. Routine checks are cheaper than replacing entire magnetos.
-
-
🔁 Service Bulletins & ADs
-
The inspection ensures you're in compliance with all current Service Bulletins (SBs) and Airworthiness Directives (ADs) many of which address safety critical issues

Aircraft Magneto Overhaul: What It Is & Why It Matters
What Is a Magneto Overhaul?
An aircraft magneto overhaul is a complete disassembly, inspection, and rebuild of the magneto according to the manufacturer’s specifications. It restores the unit to “like-new” condition and ensures full compliance with FAA regulations, Airworthiness Directives (ADs), and Service Bulletins (SBs).
What’s Included in a Magneto Overhaul?
At CrossFire Magneto, our overhaul process includes:
-
Full Disassembly
-
Every component is removed, cleaned, and inspected.
-
-
Critical Parts Inspection
-
We measure everything per the manual and replace all worn, aged, or out-of-spec parts.
-
-
Component Replacement
-
Bearings, impulse couplings, brushes, gears, coils, and points are replaced as needed with high-quality FAA-approved parts.
-
-
Compliance Check
-
All Service Bulletins and Airworthiness Directives are reviewed and complied with.
-
-
Reassembly & Timing
-
We reassemble with precision and set the internal timing for optimal performance.
-
-
Final Testing
-
Every magneto is bench-tested to verify spark energy, impulse coupling operation, and RPM drop.
-
✅ Why Overhaul a Magneto Instead of Replacing It?
-
Cost-Effective: A quality overhaul can save money vs. a brand-new unit.
-
Warranty: Our overhauled magnetos come with a 500-hour or 1-year warranty.
📆 When Should a Magneto Be Overhauled?
-
Signs of trouble: Hard starting, rough running, or high mag drop?
IT MAY BE TIME
🔧 Aircraft Magneto Repair: Fast, Accurate, Reliable
✈️ What Is a Magneto Repair?
A magneto repair focuses on fixing specific issues or replacing failed components without performing a full overhaul. It's ideal when your magneto is mostly in good condition but needs targeted service to get back to airworthy and reliable operation.
🧰 When Do You Need a Magneto Repair?
You may need a repair if you're experiencing:
-
Rough engine operation
-
Hard starting or engine misfires
-
Unusual mag drop during run-up
-
Oil, moisture, or carbon tracking inside
-
Timing issues or weak/no spark

-
-
Disassembly & Inspection
-
We check critical areas like the points, coil, bearings, and distributor block.
-
-
Targeted Part Replacement
-
Only worn, damaged, or failed parts are replaced, saving time and cost.
-
-
Reassembly & Timing
-
We reset timing and ensure proper gear alignment.
-
-
