30 Apr 2016 N21481 SDC (Sodus, NY) - Lake Ontario shoreline - SDC 1.3 1535.1

The cylinder break-in process continues.

Unable to fly to a destination owing to time limitations and responsibilities at home, I was still able to slip the surly bonds for a little over an hour.

The sky was wide open, blue, and gorgeous. I turned eastbound and followed the lake shore. When I reached the eastern end of the lake, I rounded the corner at the unlikely-named Mexico Bay (everyone knows that Mexico is a town in New York, right?) and continued north. Though the air possessed a biting chill, bright sunlight warmed the cockpit of my flying greenhouse. The engine hummed strongly, evenly. It was a perfect Sunday drive, even if it was on a Saturday morning.

I like this end of Lake Ontario; sandy beaches, islands, and interesting topography. The eastern shore of Ontario is as close as this Great Lake comes to being as cool as Michigan's west coast.

Southwest of Watertown, I noticed that my available time was half over and that it was time to turn around. I changed course over Stony Point (shown by the arrow on the sectional) to head south and west back toward Sodus.

Wait...was that a lighthouse down there on the point?

I circled around. Yes, it was the Stony Point Lighthouse in Henderson, NY, a nice discovery for the morning. The rocky shore reminded me of Maine; Stony Point was aptly named.

I marveled, as I often do, at the variety of color presented at the surface of the Great Lake, nuanced by depth and sunken topography. Underwater scratches near shore suggested the work of numerous boat keels against the lake bottom.

Returning home, this time over the water within gliding distance of shore, I passed the "Lakeview Wildlife Management Area", perhaps the least sexy name ever given to an interesting looking wetland.

The Warrior performed well on her new cylinder. Though cylinder head temperatures were consistent with those recorded on the first flight after maintenance, it was still early to expect a change. While I wished that the old number three cylinder had not failed, I had to confess that the compulsion to break-in the new cylinder made for an excellent excuse to fly.

29 Apr 2016 N21481 SDC (Sodus, NY) - GVQ (Batavia, NY) - FZY (Fulton, NY) - SDC 2.2 1533.8

Every twenty-four months, my transponder (per FAR 91.413) and altimeter / encoder / static system (per FAR 91.411) require inspection and certification. My "IFR cert" was due at the end of April. Ray does not do avionics work on the field at Williamson-Sodus and the technician from Canadaigua who occasionally makes house calls there was unavailable because his equipment was out for calibration.

Fortunately, Boshart Enterprises at the Genesee County Airport had an open slot. Brian, who installed my audio panel, GNS-430W, and GTX-330 ES transponder was no longer employed at the shop, but I was able to schedule with Jake.

Consistent with the on-going need to break-in my new cylinder, I flew for an hour prior to landing in Batavia for my 10:00 am appointment. I ranged eastward under a clear sky, roaming along the familiar Lake Ontario shoreline.

I flew as far east as the Oswego River before turning 180° to the west and flying back past Sodus on the way to Batavia.

Westbound, I crossed between the city of Rochester below and an overcast above.

When I as just north of Greater Rochester International, a bright light caught my eye. It was the landing light from a commercial airliner settling onto runway 4. Say what you will about Allegiant Air, the pilot flying this ship put it right on the center line.

I landed on runway 10 at Genesee County with a slight left crosswind. Though it was sunny over Sodus and Oswego, a light rain had begun in Batavia.

While Jake brought the Warrior inside to begin the IFR cert, Carol gave me a personalized tour of the new building that would house the FBO, Boshart Enterprises, P&L Air (the ironically named flight school on the field), and (someday, hopefully) an airport cafe. Though Carol was frustrated with managing the logistics of relocating the shop, it appeared to me that it will be a great facility for them once the pain of moving is over.

Jake used my airplane to train the new avionics technician on how to do an IFR cert. Though he arrived with military experience, the new guy was unfamiliar with General Aviation equipment and practices. This training made the certification go longer than usual. In the process, Jake discovered that Brian had checked the new transponder when he installed it in November, putting its inspection schedule out of sync with the rest of the system. Jake redid this work so that everything would come due at the same time, but did not charge me for the duplicated effort. Boshart Enterprises has always treated me well.

Because the certification continued through lunch, I had pizza and wings with the staff. When invited to join, I declined because I did not have cash to pay for my share of lunch. Carol insisted that I join and kindly covered my portion.

In telling Helicopter Ray about it later, he summarized by saying, "So, you got a full IFR cert for the cost of a VFR cert and then THEY bought you lunch? Sounds to me like you ripped them off!" Thanks, Ray. I hadn't thought of it that way.

With all of my FAA regulatory requirements satisfied for 2016, I departed from Batavia in light rain. I added another hour of flight time to the engine by flying to the Oswego County Airport (FZY or "Fuzzy") for fuel, then flew a meandering course back to the Williamson-Sodus airport via Canandaigua.

Airplane Doctorin'

Recent research suggests that the annual physical exam has done little to impact mortality rates despite costing billions annually. Some doctors no longer recommend them, though mine is not one of them. However, when it comes to annual inspections for aircraft -- particularly older aircraft -- I think their value is self evident. My experience in 2016 serves as a perfect example.

For the first time in twelve years of ownership, I was not an active participant in the drop-off process for the Warrior's inspection. Ray (disambiguation: "Helicopter Ray") simply retrieved the Warrior from my hangar and went to work.

Beforehand, I submitted a short list of squawks. A cracked oil cooler flange (discovered during the trip to Knoxville), a bit of oil seeping from the forward portion of the crankcase that Ray was already monitoring, and a couple of difficult hot starts reminiscent of the behavior observed when the coil in the left magneto went bad previously (a factor in the infamous carburetor fire of 2012).

The Warrior's oil cooler hangs on the back of the engine behind cylinder #4, adding a significant, vibrating mass to the baffling on that quarter of the engine. Fatigue cracks on the baffling nearest the oil cooler have been a consistent problem over the years, but now the cooler itself was cracked. This imperfect engineering explains why so many other designs place the cooler directly on the firewall and simply duct cooling air to it. When Ray removed the oil cooler, he discovered that it was cracked in more places than either of us realized and deemed it not worth repairing. A new oil cooler was soon hung from the same precarious position on the back of the engine occupied by its predecessor.

I had correctly diagnosed that the left magneto had an issue, but my focus on the coil was misplaced. Rather, the mag timing had slipped to a point where the coil was not firing at the proper time and this was the cause of the starting issues. Frankly, it is amazing to me that the mag timing could be so far out of tolerance, yet the engine ran well and passed every pre-flight magneto check.


On April 19, I received this worrisome text from Ray:

"Good morning, Chris. Call me when you get a chance."


I don't know which troubled me more, the vagary of the message or the fact that the laconically blunt aircraft doctor had bothered to type a pleasantry like "good morning" into his phone.

Cylinder number three did very poorly during the compression test. When Ray investigated, he found that the exhaust valve was in rough shape, invoking the technical term "hammered" when describing it to me. Investigating further, he found two cracks in the cylinder. The fact that the Lycoming powerplant performed so admirably on our most recent cross country flight to Knoxville, TN is a tribute to its robust design.

To be fair, I have been watching this cylinder since 2008. It has returned some erratic compression numbers in the past and, a few years ago, the shop did some work on the exhaust valve seat to improve the seal. I suspect that poor cooling on that cylinder, which passed undetected until I installed an engine analyzer, to be the underlying cause. I will never know for certain.

Thus, after roughly 1300 hours in service, Warrior 481's powerplant needed a new cylinder. Ray installed a nickel cylinder from Penn Yan Aero, changed the oil to an 80 weight mineral oil, and instructed me on proper break-in procedures. I will need to run at 75% or higher power and fly at least 30 minutes each flight without power reductions. This means no touch-and-goes, no short hops, and, though he did not forbid it, droning around at reduced power on instrument approaches is probably inadvisable as well. He indicated that the cylinder head temperature on number three would run hotter than the other cylinders for a time, but likely drop once the cylinder was broken in.

25 Apr 2016 N21481 SDC (Sodus, NY) - 5G0 (Le Roy, NY) - SDC 2.0 1531.6

I was anxious about the first flight after the airplane equivalent to open heart surgery (after all, it was a valve replacement). Improper torque on a bolt could lead to the departure of a recently installed barrel and that would make for a really crummy day.

Darrell had dropped off his airplane with Ray that morning and needed a ride home to Le Roy. We fired up the Warrior with this dual mission in mind. Having Darrell along for the first flight increased my anxiety, but he understood the risks as well as I.

When the engine fired, the airplane vibrated significantly like a wet dog shaking water from its coat. The engine monitor showed temperatures coming up on the pre-existing cylinders, but number 3 remained cold. With oil pressure looking good, I fed in some throttle. Over 1000 rpm, the engine suddenly smoothed and the temperature on number three rose to match those of its mates.

Disconcerted by the initial roughness, I suggested we taxi to the runway and evaluate how the engine performed on run-up. Darrell agreed.

At the departure end of runway 10, I locked the brakes and brought the engine to 2000 rpm. It ran smoothly with cylinder head temperatures rising appropriately. I completed the pre-flight run-up and returned the engine to idle. It continued to run true.

Satisfied, I keyed the microphone to announce our departure. I could hear from the side-tone that something was wrong. There was no "pop" when I keyed the push-to-talk button. The audio panel and the GNS-430 both indicated that I was not transmitting. I reached over to the right side yoke in front of Darrell and tested the push-to-talk switch there.

Pop...pop... Clearly, there was a bad connection in the circuit leading to my push-to-talk switch.

I aborted the test flight and taxied back to Ray's hangar, where he quickly found and repaired the broken wire to the pilot-side push-to-talk switch. With that, Darrell and I were ready for a second attempt at a test flight that would, hopefully, culminate in his safe delivery at the Le Roy Airport.

The second time around, the engine idled smoothly on initial start. After a successful run-up, we launched from runway 10, quickly climbed to 3,000 feet, and circled the Williamson-Sodus Airport. While I managed the climb-out, Darrell monitored engine temperatures and oil pressure. Circling the airport at 75% power, the engine continued to run smoothly. Cylinder head temperatures for the old cylinders fell into their usual 345°F range and, consistent with expectations, number three ran hotter at 385°F.

After a few circuits of the field, we reached consensus that all was well and set course for Le Roy, taking comfort in the fact that Greater Rochester International lay close to the direct route if anything went wrong.

Of Cylinder Replacements and Farmer's Fields

On the ground at Le Roy, Darrell and I were met by Ray, our good friend and the owner/operator of the airport (not to be confused with "Helicopter Ray"). He was mowing when we landed and, recognizing the Warrior, parked his John Deere next to us on the ramp. I do not know whether he heard it from Darrell or "Helicopter Ray", but Ray was already aware of the Warrior's cylinder transplant operation.

Always ready with a story pertinent to the situation, Ray regaled Darrell and I with a tale from his time running the Hylan School of Aeronautics. He dispatched a pair of younger pilots to Watertown, NY to retrieve a flight school aircraft that had undergone similar engine work after an outright engine failure in northern New York state. He advised them to circle the Watertown airport for a few minutes  after take-off before going cross-country in the repaired aircraft. The pilot flying the mended Cherokee did not heed Ray's advice and found himself putting the airplane into a farmer's field on the outskirts of Watertown after suffering an engine failure minutes after departure. The farmer loaded the crippled Cherokee onto a cart and treated airplane and its pilot to a hero's parade through Watertown on the way back to the airport. The young pilot had made a textbook off-airport landing without damaging the airplane, property, or livestock. Of course, had he followed Ray's recommendation in the first place, he would have been able to put the airplane back down at the airport without the necessity of a parade.

Darrell and I assisted Ray in moving a damaged Cessna 172 that had taken its elderly pilot for a ride several months earlier. It had scraped along the side of the old T-hangar structure at Le Roy. The Skyhawk's joyride ended when its propeller sliced completely through the hangar wall (explaining the sheet of plywood on the side of the hangar) and totaled an innocent aircraft resting inside. The 172's left wingtip was shredded and the propeller was completely mangled; it was twisted, bent, and deeply notched in places. It was an unfortunate demise for an otherwise honest, late 1960s-era Cessna.

Physical Therapy

I launched from Le Roy with a goal of contributing another hour toward the break-in of cylinder three. I flew to Geneseo, circled the National Warplane Museum, and noted that their C-47 D-Day Veteran, Whiskey 7, was parked outside on the grass.

With the engine humming strong and smooth at 75% power, the airplane and I flew around the region at 3,000 feet. Cool, silky smooth air pushed our indicated airspeed into the bottom of the yellow arc as we hopped from airport to airport, first flying west toward Perry-Warsaw Airport, then back over Geneseo, Canandaigua, and Finger Lakes Regional in Seneca Falls. With nighttime rapidly drawing a shroud across the landscape below, I finally returned the Warrior to Earth at Sodus.

With two hours down, there are several more required on a modified flying regimen before the airplane will be back to herself again, but the road to recovery appears to be progressing well.

The Flower City

I was out and about today, exercising a ship that has not been airborne since our return from Knoxville, TN two weeks ago. I had occasion to fly directly over Rochester, the "Flower City", and this is what I saw.

Departing Sodus, the Warrior was showing some wing over the "North Coast".

Landmarks in this photo include Village Gate, the industrial complex at the bottom of frame that has been transformed into restaurant and retail space, and the Memorial Art Gallery.

Downtown is encircled by the Inner Loop. Or, it was until they started filling it in (see the portion in the lower left corner of frame).

If you squint just right, you might  make out the renowned Eastman School of Music toward the lower left of frame.

Several downtown landmarks have undergone recent name changes. The three tallest towers from left to right are the Xerox Tower, Legacy Tower (formerly the world headquarters of Bausch & Lomb), and The Metropolitan (formerly the Chase Tower).

High Falls, where the muddy Genesee River tumbles over a cliff on the north side of the Inner Loop on its way to Lake Ontario. The best view is from that bridge opposite.

From left to right are Downtown United Presbyterian Church, also known as DUPC (pronounced "doop-see") where Kristy rehearses her chorus each week; Frontier Field, home of the Red Wings (the ones that carry bats instead of hockey sticks, which is still very confusing to me); and the headquarters of Kodak.

Frontier Field is not a massive stadium, but it's a nice place to while away an afternoon, depending on one's tolerance for baseball.

The flight over the city lasted for only a few minutes, but served up a host of fond memories of my time in Rochester.
