The realization of a boyhood dream... Private Pilot July 17, 2006 - Instrument Rating August 19, 2010
Merry Christmas to all of our readers and best wishes for a Happy New Year!
To all of you that share our passion for flight we hope you enjoy the adventures that 2024 will offer.
Pilots need to understand that authorized preventive maintenance cannot involve complex assembly operations. As an owner/pilot one should carefully review 14 CFR Part 43, Appendix A, Subpart C (Preventive Maintenance), which provides a list of the authorized preventive maintenance work that an owner pilot may perform. As owner/pilots we should conduct a self-analysis as to whether you have the ability to perform the work satisfactorily and safely.
Time to expand my owner maintenance activities. I fondly look back to work completed on my Sundowner when things were simple and straight forward. Since owning a complex aircraft there are more bits and pieces that need inspection and items that can cause headaches.
Lets look at a simple battery replacement. my Sundowner required two screws to be removed in order to gain access behind the baggage compartment bulkhead. The battery box opened up with ease and even my broken body could squirm around to yank both batteries out.
Commander Battery replacement requires two rear bulkhead panels to be removed which includes many screws and wiggling into positions this body can hardly perform. None the less the bulk head is opened up and now lets get to that box. Six screws, three a side, and having to reach behind the gear motor access panel. These fingers are no longer as nimble as they once were so extra care was taken not to fumble and kiss the screws goodbye as they disappear into the belly of the beast.
My Concorde RG35 AXC was last replaced eight years ago this month. I noticed the last two times starting it moved the prop with an I'm not happy grunt and then nothing, same result after another try. On the third attempt it came to life.Not my battery minder, just a sample of what was represented |
I have also had a gear down and locked indication issue. I can clearly hear the three gear clunk into position but I would feel much better with a consistent "three green". My last few flights I have used the tail camera Bluetooth to visually confirm what I heard.
My Investigation
I pushed the protective shield up the wires to expose where I saw a change in the shape of the insulation. Sure enough with a slight tug the one wire fell apart and the other two look ready for the same fate. I believe the protective plastic shield became brittle and the wires would bend or kink just enough to wear them out in the last three years, since I last had that switch replaced. This year I am going to have the shop wrap the wires with a flexible wrap.
Teflon spiral wrap |
1ES1 Switch |
JE-5 Lever and roller |
The switch is a Honeywell 1ES1 that I will have replaced and if you look closely the Honeywell JE-5 articulating arm and roller are looking pretty rough so I am going to replace that combo too.
I ordered the parts and will make an appointment once my new battery is installed. Sussex Aero is just a ten minute hop or I'll head north to New Garden, about forty-five minutes. Either flight will be gear down situation, not wanting to mess with the broken wire.
Saturday 12.9
The couple we were going to meet with canceled because their Mastiff was having white blood cell count issues. We wish Bear a speedy recovery, we would have loved hugging on him.
I turned the preheats on remotely at 5 am and made it to the airport by noon. I completed my preflight and sump prior to opening the hangar door. When it was time to get the fan turning 3 Tango Charlie wouldn’t even turn a full blade. I tried a few more times and then she came to life. I have no clue since the battery minder was showing full charge and the JPI confirmed 13.9 volts.
I taxied out for runway two-zero and launched into a beautiful day. The plan is to fly up the coast, enjoy the view and then turn around over Cape Henlopen and come home, maybe shoot a practice approach before landing.
The flight was great and I set up for the RNAV GPS 14 approach into Ocean City. There was plenty of activity today. I even had one plane coming head on , same altitude, while shooting the practice approach. ADS-B is a real life saver.I ended up breaking the approach off and point south to fall in behind two other aircraft that were also inbound to land on two-zero. I was now number three even though the aircraft that was number two offered me a chance to enter ahead of him. I respond no thanks I am just enjoying the sunshine, his reply, he was too. I made a nice landing and taxied for the hangar. Once 3 TC was tucked away. I made the lunch run pick up then headed home.
