N22309: an unlucky number

My U.S.-manufactured 1979 Piper Warrior II was originally registered as N22309, until it was imported into Alberta, Canada in 1988 and reregistered as C-FBJO. It wasn’t the only plane to use that registration number.

The first N22309 that I can find was a Cessna 150 based in the Phillipines. On 28 May 1973, a solo student pilot was executing a go-around (touch and go?) at Plaridel Airport before heading to Clark Air Base. Unfortunately, things didn’t go so well, and the plane ended up flying into the trees. The 35-year-old student pilot survived, but the plane was a write-off (summary).

The N-number lay dormant for six years, until it was assigned to a new Piper Warrior II in 1979. The plane kept the number until 1988, when it was exported to Canada (and later bought by me in 2002).

The N-number lay dormant for another seven years, then was reassigned once again in 1995, this time to a Ryan RX-6 (a type I can find almost nothing about). The plane didn’t have it for long, however — it was canceled in 1998. All the database says is “Reason for Cancellation: Destroyed”. There’s no accident report in the NTSB database, so let’s hope it was destroyed while parked on the ground, with no one in it. The number has been available for 10 years now.

Anyone interested in a slightly used N-number?

Cost of owning a plane in 2007

Here’s what it cost to own and operate a 1979 Piper Warrior II in Ottawa, Canada in 2007 with 80 hours air time (a bit more flight time, of course). Since the US and Canadian dollars are basically at par now, there’s no need to convert:

Item Total Hourly
Fees: $1,112.51 $13.91
Fuel: $2,945.39 $36.82
Other consumables: $247.79 $3.10
Insurance: $1,458.00 $18.23
Maintenance: $2,437.39 $30.47
Reserves $1,600.00 $20.00
TOTAL: $9,801.08 $122.51

These are real costs, including sales taxes, not the BS costs you hear people throwing around at the airport. Reserves are $20/hour for engine and paint. I also pay about $500/year for charts and recurrent training, but I’d pay the same as a renter, so I don’t count those as ownership costs.

2007 was by far the cheapest year I’ve had with C-FBJO, and also the fewest hours I’ve flown (I’m usually over 100). I was parked at a less expensive airport and used less gas (flying less), but the biggest difference was maintenance — annual maintenance for a small plane like mine can be $2,000 one year and $10,000 the next, depending on what goes wrong (and even the simplest plane has a lot that can go wrong). I’m keeping a nearly 30-year-old plane operating, so stuff wears out and has to be replaced all the time, just as it would with a 30-year-old car; unlike with cars, however, buying a new plane isn’t a solution — I read recently that routine inspection and maintenance for an SR-22 runs $8,000-$10,000, and that’s without any problems coming up.

Fees include tie-down (and required club membership) at my home airport, transient landing and parking fees during trips, and the compulsory $75/year Nav Canada and $27.50 US customs fees. Consumables are oil (mainly), filters, fluids, etc.

When so many of the costs — tie-down fees, insurance, and (most) maintenance — are fixed, I can see the logic in taking one or two partners. You’ll still pay just as much for fuel and engine/paint reserve, but you slash the other overheads. I don’t think I’ll take a partner in C-FBJO at this point, but if I move up to something bigger like a Cherokee Six, I probably won’t try it alone.

So where did this money take me and my passengers (besides the Ottawa area) in 2007? In chronological order, Maniwaki QC, New York City (Teterboro), Drummondville QC, Pembroke ON, Toronto ON (Buttonville), Sault Ste. Marie ON, Toronto ON (City Centre), Brockville ON, Waterloo ON, Toronto ON (Buttonville) again, Sundridge ON, Sault Ste. Marie ON again, Toronto ON (City Centre) again, Burlington VT, Boston MA (Norwood), Alexandria Bay NY (Maxson), New Jersey and New York City (Caldwell), Montreal QC (Trudeau), Baie Comeau QC, Maniwaki QC again, and Burlington VT again. Not all that exciting a year, but it kept the rust off the wings (mine and the plane’s).

Dead airspeed indicator

The incident

I flew through some light snow showers on my way to Kingston with my daughter this morning, so I turned on the pitot heat just before joining the circuit to make sure the pitot blade was clear. At the end of the downwind leg I slowed the engine, reduced power, dropped flaps, verified 70-80 knot airspeed, turned a tight base over the icy water of Lake Ontario, then looked again at the airspeed indicator (ASI).

35 knots. Way below stall speed.

But the plane was flying fine. The nose wasn’t high, the controls weren’t mushy, the stall buzzer wasn’t blaring, the wings weren’t buffeting, and most importantly, the ice floes weren’t spinning and getting larger in the windshield. I gently pushed the nose down enough to speed up 5-10 knots, but still the needle didn’t move. I checked the altimeter and it was behaving properly, showing a slow descent towards field elevation. That meant a pitot failure.

The trickiest part was the turn to final, almost immediately after the failure, when I’d barely had time to process it — it’s easy to lose airspeed in a turn, even with a functioning ASI. After that, it was pretty much a normal approach and landing (no point declaring an emergency when the runway is less than a minute away). The ASI flickered back to life on short final to show that I was 5-10 knots above my normal approach speed. It froze again at some point during the flare and landing (I don’t look at the panel once I’m past the airport fence), then gradually climbed to 90 knots as I taxied in to park the plane.

The aftermath and resolution

I called an AME (mechanic) at the airport, tested the pitot system by blowing gently into it (no joy), then went out for lunch so that I wouldn’t stay around fretting. Three hours later, the AME hadn’t had time to get to the plane yet, and the ASI still wasn’t responding to the blow test, so I decided to try something else (with the AME’s blessing): I started the plane, turned on the pitot heat, then did a high-speed taxi down the 5,000 ft runway.

The needle climbed again during slow taxi, then dropped at the start of my high-speed run, then climbed up again — then, suddenly, at the very end, it started responding normally. Since there was no other traffic, I turned around and did the same thing the other way, and this time, the needle responded normally the whole way. I taxied around, did pre-takeoff checks, then went back to the runway for a real takeoff roll, prepared to abort halfway if the ASI wasn’t behaving — no problem at all, all the way home (though my mode C encoder started acting up, because there’s a law of physics that at least one thing always has to be broken on an airplane).

The analysis

There must have been some snow or ice near the opening of my pitot blade. Turning on the heat partly melted it and let it get into the (pin-sized) hole, and the water blocked the pitot line, possibly as slush or even a tiny ice crystal. My high-speed taxis, combined with the pitot heat, forced the blockage the rest of the way through the line and cleared it.

Pitot heat on was a good idea, but turning it on just before joining the circuit wasn’t. Lesson: make as few configuration changes as possible when you’re close to landing — if something’s already working, why mess with it? If I’d turned on the pitot heat 10 or 15 minutes earlier, I would have had the ASI failure at 5,500 ft, where it was no risk at all, instead of in the most dangerous possible phase of flight, and it would have worked itself out before I had time to land anywhere. Since I hadn’t turned it on earlier, I shouldn’t have turned it on at all.

In the end, no harm, no cost, and a little bit of extra confidence that I can handle a plane by feel when the ASI fails, at least in VMC.

OurAirports: terrain view

A couple of months ago, Google Maps quietly added a Terrain layer to their maps. I’ve enabled that in OurAirports now, so that you can get at least a rough idea of the terrain around an airport (or in a region, country, etc.).

For example, here’s why there are so many accidents around Hope, BC when the weather gets low.

Gimli glider's last Air Canada flight

You’ve probably all seen this already, but today the Gimli Glider takes its last flight as an Air Canada aircraft, almost 25 years after its famous power-off glide to a landing in Gimli, Manitoba.

The original pilots and some of the crew members are on board as it heads from Montreal to Tucson on its way to a bone yard in the Mojave desert.

It's the runways, stupid

Here’s a statement from the U.S. Air Transport Association (ATA) — the airlines’ lobby group — about variable landing fees for U.S. airports (e.g. higher at peak times, lower other times):

“Unfortunately, [the policy] does nothing to fix the primary cause of delays – our nation’s increasingly antiquated air traffic control system,” ATA CEO Jim May said. “Additional fees . . . will only increase the cost of flying for the consumer.”

Yes, the U.S. ATC system is antiquated, and yes, higher peak-hour fees at big airports may mean higher ticket prices, but how is ATC the problem? Flights don’t get delayed because a controller has to use a voice line to coordinate hand-offs or stare at a cold-war era radar screen; they get delayed because runways at big hubs can handle only a limited number of landings per hour. The proof is in the fact that there are almost never delays flying to small airports. (Ever had a ground hold waiting to fly to Massena, NY? Didn’t think so.)

Let’s make it really easy for the ATA:

  • Big airport (called “hub”) has one active landing runway.
  • Runway can handle 40 landings every hour.
  • Your members (airlines) schedule 50 flights per hour into the hub.
  • Planes land late.

Give the FAA as much new shiny technology as you want, but if there aren’t enough runways, it won’t help. Do you really want to be flying heavy jets a minute apart or less? Fancy navigation technology won’t get rid of wake turbulence.

OurAirports: heliports and floatplane bases

OurAirports now includes heliports and floatplane bases as well as fixed-wing airports: in the last 24 hours I’ve added 828 floatplane bases and 5,911 heliports, all from Canada and the U.S. (and a couple of U.S. dependencies like Guam).

Here’s a screenshot of a map of the Vancouver area — you should be able to make out 3 floatplane bases, 7 heliports, and 6 airports (you can jump to the live map to explore further):

Screenshot of Vancouver map

Thanks again to George Plews for collecting the Canadian data. Does anyone have a good reference for heliports and floatplane bases outside of Canada and the U.S. (or even for more fixed-wing airports)?

Add local places to airports

Any logged-in member can now add placemarks to the map for local spots at an airport (FBOs, visitor parking, fuel, restaurant, customs, or whatever), and more importantly, anyone — even Anonymous Flyers — can comment on those spots.

Take a look at Ottawa Rockcliffe or Teterboro to see some examples, then mark some of the spots at your local airport so that I’ll know where to park, fuel up, and eat next time I fly in.

Global orgasm for peace

Pilots often already have their watches set to UTC, so this should be easy. At the exact minute of the winter solstice tonight, at 06:08 UTC, is the second annual Global Orgasm for Peace

To effect positive change in the energy field of the Earth through input of the largest possible instantaneous surge of human biological, mental and spiritual energy.

The web site doesn’t specify that this has to happen in pairs — presumably, it helps the Earth’s [their capitalization] energy field just as well alone or even in groups.

If you need to be behind the controls of an aircraft at 6:08 UTC, however, you might want to substitute eating chocolate.
