136 – Engine Oil Leak: How Much is Too Much?

Engine oil leaks are a common problem on small airplanes with piston engines. But how much oil leakage is too much? Here’s an indicator: If there’s oil on the nose tire, and it paints a stripe on the pavement with each revolution, that’s too much oil leakage. This was the case the other day on […]


135 – Carl Valeri: Airline Pilot, Piper Pilot, and Aviation Careers Coach

Since that time, he’s been an airline pilot, flight instructor, aviation careers coach, mentor, Piper Cherokee pilot, and many other things. Carl is well known as the host of two podcasts, the […]


134 – An Unlikely Cause for a Hot Mag on a Cirrus

“There’s no RPM drop when I select left mag, and if I turn the ignition switch off, the engine continues to run.” That’s what the owner of this Cirrus reported when he arrived at our airport the other day. One of our technicians got to work to troubleshoot the problem. Here’s what he found: The […]


133 – The Firetrucks Rolled When a Navajo’s Landing Gear Did Not Extend

I was sitting in my car that day, having lunch with my friend Matt, when we noticed the airport fire trucks were rolling out toward the runway. Although they exercise these trucks regularly, this time seemed different. And sure enough, a Piper Navajo made a low pass and it was obvious the landing gear was […]


132 – Real Inflight Magneto Failures & Troubleshooting

Note: scroll to the bottom of this post for a special announcement. Have you ever experienced an inflight magneto failure? If not, you might some day… but if you take action on the recommendation in today’s episode, you can dramatically reduce the likelihood of that happening. The left mag on this Cessna 172RG failed in […]


131 – Drew Wright’s Cessna 182 Exhaust Valve Lapping Success!

During the recent annual inspection on Drew Wright’s Cessna 182, cylinder #1 had a low compression of 42/80. However, with the amazing technology of borescoping, he was able to take a look inside the cylinder. The nice concentric circle of deposits on the face of the exhaust valve indicates a healthy valve. Drew wondered if […]

129 – Air Filters: Don’t Let Your Airplane Suffocate!

Whether your airplane has a “Brackett” brand filter like the first picture, or a “Donaldson” brand filter like the second filter, or another brand like “Challenger” or something else, they all need to be clean and in good condition. The air your airplane breathes is critically important. Your engine, your vacuum instruments, and even other […]


128 – Should I Buy a Twin Cessna or a Beech Baron?

In this week’s episode, we are talking about upgrading to a twin, and some thoughts about choosing between a twin Cessna and a Beech Baron. Thank you Simon Cail, for your email, and for permission to read the email in this episode. Simon’s decision was between a Cessna 340 and a Beechcraft Baron 58. The […]


127 – No Oil Pressure in a Cessna 150

My friend Matt and I had a plan, and it was going to be an awesome adventure. The crisp, clear morning was as nice as we could hope for on a November day in Virginia. The half hour drive from my house to the small town New Market Airport was absolutely refreshing… exhilarating even. As […]


126 – Magneto Trouble at Higher Altitudes

Corrosion in the towers of a magneto can cause high resistance, and the problem will be magnified as you go up in altitude. This green corrosion could likely be cleaned up and it may improve some, but it may also indicate a good time to perform either a 500 hour inspection or an overhaul on […]


125 – Engine Failure – What Would You Do In A Moment’s Notice?

Not long ago, there was an unusual engine failure in a Cessna 182 at Shenandoah Valley Regional Airport. Cindy Ferek was the flight instructor on board that day, and she landed the airplane safely on the runway. Before we get into that story, I’d like to introduce Cindy. (The Cessna 172 in the following picture […]


124 – Owner Maintenance and Cessna Fuel Strainers

Before we get to the fuel strainers, here are some highlights from the past couple weeks: Our local EAA chapter had its annual pig roast / fly-in / picnic at Sheldon Early’s “GMI” Greenmount International – a fun name for a country grass runway. It was a perfect evening with a bunch of great people. […]


123 – Upside Down in an RV7!

An outstanding pilot gave me a ride in his RV7 this week, but before we get to that, here are a few things we’re talking about in this episode: A crazy wiring situation in a Cessna 180. Check out the wiring pieces I saved after installing a new wire under the instrument panel… 2. Replacing […]


122 – THAT scared me! (A Wheel Story)

I saw something not long ago while changing an aircraft tire, and it startled me for a bit, until one of my co-workers helped me remove the danger. Here’s what I saw: The picture above might look fairly normal, until you notice the bulge up near the brake disc. Take a closer look in the […]


121 – When to Fire an A&P

Is there ever a good reason to fire an A&P? I think so… and in today’s episode, we’ll talk about some evidence for one of those times. Scroll down for the appalling pictures I took recently! But before that, I want to share some inspiring information related to the amazing Stinson family of airplanes. And… […]

119 – Sneak Peek of Dean’s Oshkosh Presentation

Scroll down to check out Dean’s favorite borescope. I have three kids, and those are my two oldest… from many years ago 🙂 Morgan, my oldest, is on the left, and Seth is on the right. I’m guessing they were around 9 and 7 years old at that time, and they’re now 22 and 20! […]


118 – Airplane Maintenance: Too Much or Too Little?

Sometimes small, general aviation airplanes get too much maintenance, and sometimes they get too little. We talk about that in today’s episode along with some real life examples. But first, I want to give a shout out to two people I have absolutely loved learning from recently because they are both excellent teachers. Chris Palmer: […]
