Powered by Lycoming

About 80% of general aviation aircraft fly using Lycoming engines. Clearing the trees at the end of the runway. Leaving 4500ft for 6500ft. Maintaining airflow and generating lift across the wings. All are impossible without a reliable engine. Lycoming powers my training aircraft and so fuels my quest for a private pilot certificate. This blog is a record of my thoughts and experiences on life, flight, and learning.

It was time for the annual inspection on 6G, and so I went up with Dad to see our C172 with all of the access panels open. We had the work done at Missionary Maintenance (MMS). I have helped a friend of mine pound thousands of rivets together to build an RV-6, so I had some inkling of what the internals of a general aviation aircraft looked like. It was pretty interesting - really, there's not too much to a Cessna but the airframe, a simple carbeurated engine, a vacuum system, an alternator, and some flight controls.

I have been around large commercial aircraft undergoing A, B, and C checks at Mexicana, Northwest Airlines, Air Canada, Delta, Aer Lingus, and others, and so I have spent a fair amount of time in aircraft shops, and I have to say that I was very impressed with the thoroughness of MMS. They really take a lot of time and seem to really pay a great deal of attention to small details. Of course, the annual inspection is a thorough process as mandated by the FAA, but you can tell the difference between someone that takes their job seriously and someone who is punching a time clock. I was impressed.

Here are a few photos of the airplane through the inspection...

You can clearly see erosion of the used sparkplug versus the newer one.

Ran across a couple of old photos today of a trip I took to the UK in 2002 for my job, and thought to share some of them. I used to work for a 2nd tier aerospace supplier as a customer support engineer for commercial aircraft wheels and brakes. Sounds exciting, huh? Well, it generally was - it also required some amount of travel, which was pretty fun. In summer 2002, I spent two weeks in the UK and had a blast. basically, I went around collecting data for service problems, looking at failed parts, and interviewing shop managers. In a typical two weeks, I would visit several customers, Monarch, JMC, Air2000, British Airways, Aer Lingus, Virgin, Middle East Airlines, deliver a presentation on service fixes, go out to lunch, perhaps conduct some training associated with a new service letter or bulletin, deliver new replacement parts, and a host of other good will gestures towards our customers. It was fun, and I got to hang around airports all day!
