Episode Info:

Here are some recent happenings, straight from the shop at Classic Aviation, LLC:

Birds in the cowling!

It’s bird nest season, and they are driving airplane owners crazy by building nests on top of engines.

Listen to today’s episode to hear about a Bonanza owner with 2 nests on his engine after a short stay at Shenandoah valley.

And here’s a Cessna 182 that came into the shop for some maintenance. When it’s nesting season, the birds don’t waste any time making a safe place for their eggs.

Corrosion on the battery terminals!

Here’s what the battery terminals looked like on a Cessna 182 that stopped at KSHD due to an intermittent electrical charging system:

The negative terminal was severely corroded.The positive terminal had some minor corrosion as well.

Reminder: As an airplane owner, you can help ensure reliable electrical system operation by keeping your battery terminals free of corrosion.

It’s a good idea to check these terminals at least once in between your annual inspection, and apply some anti-corrosion spray.

Rough engine: Is it spark plugs, or a magneto?

Here’s a spark plug from a Piper Apache that had a rough mag check.

I received an email from the flight instructor and he was suspecting a magneto problem.

However, after some troubleshooting by running the engine, watching the JPI engine monitor, and removing the specific, affected spark plugs, it turned out there were actually 3 fouled spark plugs!

One way to avoid fouled spark plugs, is to aggresively lean the mixture while taxiing around on the ground at low RPM’s.

It’s amazing how much you can lean the mixture on the ground at 1000 RPM and still have the engines run smoothly during taxi operations.

AND, with the mixtures this lean, there is little chance of forgetting to enrich them for takeoff, since the engines will likely not run well if advanced to takeoff power.

For this reason, during taxi operations, it’s good to lean until the engine almost quits, and then enrichen enough to run smoothly.

If you only lean slightly for taxi operations, you risk forgetting to set the mixtures for takeoff.

Here is how I was able to set the mixture controls in that Piper Apache on the ground at 1000 RPM’s, for smooth ground operations.

So, that’s all for this week.

Remember:

Keep the birds out of your cowling if your airplane is parked on the ramp.

Keep your battery connections free of corrosion for reliable electrical system operation.

And consider how you can lean your idle mixture for cleaner spark plugs during taxi operations.

Have a great week!
