En route to the Bahamas for a January vacation with my wife who was 4 months pregnant at the time, we ended up AOG in Brunswick, GA. We had been experiencing a minor prop seal leak, but had been told independently by three separate A&Ps that it was not a big deal and to take care of it at annual (early February).
It turns out that the problem was exacerbated by oil viscosity and 7+flight hours toward the islands warmed up the oil to make that oil nice and runny!
At the first fuel stop, we had a slight oil streak, which was consistent with previous flights, so there was little reason for additional concern. However, in the middle of the second leg, I noticed a new problem. Tiny little specks of oil were now propagating on the windscreen. At first, this was minor annoyance, but I soon realized that this would cause a more significant issue as we nears our destination: forward visibility!
At this point, KBQK was our intended destination, but Savannah, GA was a viable alternative. On the one hand, Savannah, being a class C would likely have more emergency equipment if I messed something up, but on the flip side, I would cause a greater disruption to commercial air traffic. A brief search on Foreflight revealed that the maintenance shop at Brunswick had helped many AOG pilots and was very well regarded.
So, in spite of possibly fewer emergency vehicles and a smaller runway (still PLENTY big for the 172) I opted to continue to the intended destination. About 20 minutes out, I asked my (pregnant) wife to climb to the back and grab the roll of shop towels. I took one, opened the window and with all the stretch that my gangly arms could muster, reached forward toward the windscreen to wipe a spot clear. Let me tell you, the windscreen is further forward than you realize! I did manage to get about a 6” wide by 12” tall section wiped relatively clean, but 15 minutes later, on the final leg of the instrument approach, it had hazed up again. Rinse and repeat.
That clear corner didn’t allow me to see straight ahead, but by flying in a forward slip, I was able to stay on center line all the way down and just kicked it straight at the end. In spite of the less than ideal situation, we were safely on the ground. We taxied to the FBO and David Manning, one of the proprietors of Manning Aviation, came out to tie us down and fuel us up. Before I had even gotten out, he asked where we were going, and when I told him that we were headed to the Bahamas, he said m, “I wouldn’t fly it down there like this.”
It wasn’t until I got out and saw the extent of the oil down the side of the plane that I concurred. This was on a Saturday night, so no A&P was available until Monday morning. However, David used his personal connections to get us a room at the local hotel for $100 less per night than the standard rate!
On Monday morning, David’s brother, a mechanic of over 50 years arrived and within less than 30 mins had the cowl off, the prop off, had identified the issue with the prop seal and told me that if he had the right seal in stock, we would be in the air by the next morning (due to the curing time necessary for the sealant). He did in fact have that exact seal in stock and the next day, we departed for our island vacation.
Some notes about our experience:
1. This was literally the week after I got my commercial ticket, so I was confident enough in my abilities to make Brunswick instead of diverting to Savannah.
2. My wife is a paramedic and makes critical decisions under pressure nearly every shift, so she didn’t panic at all. She in fact was very helpful through it all and was down to continue our journey.
3. I’ve wrestled with whether an emergency declaration was warranted, but based on a number of factors, I determined that it was not necessary. In retrospect, I wouldn’t have been out of line to declare, but I am still ok with my decision not to.
4. I can’t possibly say enough good things about the entire Manning family and crew there at KBQK. They saved our vacation and prevented an AOG on foreign soil where it might have been a WAY bigger issue.
