Pre-Flight
My condolences to you and her family.
It is with a heavy heart that I report the death of my freind Maureen McGee. She was the pilot of the 414 that went down in Pottstown, PA 12/26/06.

Bummer, sorry to hear it. It's always tough to have your friends crash. Sadly, while this may be your first, if you stay involved in aviation, it won't be your last. Welcome to the club that faces west, though it's a meloncholy club.
Johnstown, Pennsylvania
On December 26, 2006, at 1555 eastern standard time, a Cessna 414 (N400CS, file photo of type at right) operated by Flight Source LLC, was destroyed when it impacted terrain at John Murtha Johnstown- Cambria County Airport (JST), Johnstown, Pennsylvania. The certificated commercial pilot and the flight nurse were fatally injured. The flight was operating on an instrument flight rules flight plan between Morgantown Municipal-Walter L. Bill Hart Field (MGW), Morgantown, West Virginia, and Teterboro Airport (TEB), Teterboro, New Jersey. The positioning flight was being conducted under Part 91.
According to preliminary air traffic control information, the airplane was en route at 7,000 feet when the pilot advised the Cleveland Air Route Traffic Control Center that she had encountered icing, and wanted to divert to Johnstown. The pilot subsequently flew the Instrument Landing System approach to Runway 33. After descending below a 500-foot overcast cloud layer, the pilot attempted to land on runway 33, but then aborted the landing. The airplane was then observed to climb to an estimated 300 feet, bank to the right, and nose over into the ground near the center of the airport.
The investigator-in-charge is Paul Cox from the Safety Board's Northeastern Regional Office in Ashburn, Virginia. The case number is NYC07FA051.

Troy,
I plan to attend this seminar in Houston tonight... did you find it informative?
Very sad, especially when she was doing that kind of flying, enjoying it, and was so close to making it. I hate it when friends die.
So, Troy, what did they conclude went wrong?
I suppose my questions (to help my own thought process):
- If the icing was that bad, wasn't shedding, couldn't climb out of it, and made the decision to divert, why consider continuing the flight if it did shed off?
- Why not put the gear down if doing the ILS with the intent of landing, or was this likely just an oversight?
Wasn't there, and I don't have near the experience to really have a good idea of procedures there or for that aircraft to have any other ideas. Honest questions, I'd like to learn for my own thought processes.
- Why not put the gear down if doing the ILS with the intent of landing, or was this likely just an oversight?
If the ice was *really* bad, and it sounds like it may have been, the extra drag of the gear hanging out could have resulted in the plane being unable to maintain glideslope even at full power.
That thought had crossed my mind, was wondering what else.
If the ice was *really* bad, and it sounds like it may have been, the extra drag of the gear hanging out could have resulted in the plane being unable to maintain glideslope even at full power.
One other thought pops out from what I read on this thread: I think that in almost any desperate situation like this, once contact is made with the runway there's little potential advantage in attempting to abort the landing and doing so adds a huge risk. It's not certain but it sure sounds like this could have had a much better outcome had the pilot made the plane land/crash at or just after the first contact with the ground. An attempt to regain the air in a relatively unflyable airplane (carrying lots of ice and having damage from striking the ground) is just begging for a return to earth with greater vertical velocity and/or less favorable attitude.
Finally, I also questioned the stated intent to consider flying a missed approach if the airplane happened to shed some or all of it's ice load at the LOC MDA rather than planning to put the plane on the runway no matter what. For one thing, IME it takes a fair amount of time to shed a big load of ice even when the air temp is well above freezing so the time available at the MDA was likely insufficient in the first place. And there's nothing to guarantee it will shed symmetrically nor would there be much chance of determining whether enough ice came off to return the airframe to a "normal" condition. Add to that the workload issues of evaluating the sufficiency of the shedding while dealing with a barely flyable airplane compressed into the short time available at the MDA before the decision had to be completed and then needing to reconfigure if landing was the chosen option and it almost makes some sort of crash a foregone conclusion once the plan to shed ice at the MDA was hatched.
Commit to a course of action, and take the one that errors on the side of safety. When you're on the safe side of an action, stay there.
1) There was evidence of a prop strike on the right engine at the initial impact point. It is possible that the prop was damaged, and even the engine too, which prevented the right engine from producing symmetrical power on the go-around (the spin was to the right).
until you realize that the decision you made was wrong
I'm not sure how much I buy the northeast filing issue. This is the area that I'm based out of. The only time there are issues getting a slot to come in are when the weather is really bad and you're trying to get into one of the Bravos. I've had couple-hour waits for getting into PHL with bad weather, but never for any other airport, and I fly under IFR in this area a lot. Even if I change my destination from PHL to PNE (Northeast Philly) then I can get off the ground virtually immediately. I just don't see it.
gear speed on the 421 is either 160 or 165 mph. it's fairly draggy. But I thought she was flying a 414?
From the NTSB report:
An examination of runway 33 revealed an initial series of 12 gouges near the left side, beginning just prior to the 5,000-foot remaining sign (or 2,000 feet beyond the approach end of the runway.) The positions of the gouges correlated to the airplane's left engine propeller and ranged from approximately 43 inches apart at the beginning, to 47 inches apart at the end of the 40-foot series. The series veered about 20 degrees toward the runway's left edge.
until you realize that the decision you made was wrong
FWIW, I believe she was going to TEB, which I hear can be a very busy airport in some of the busiest airspace in the country.
Yeah, but I'd think that in some cases if you make a bad decision and then try to change your mind, the ensuing distraction and hasty reactions could likely be more dangerous than just going through with it. If you err on the safe side and get on the ground and stay there, well, that's probably not a bad thing.
But the point I take from that advice is, once you've committed to a course of action, it's probably safer to stay that course rather than make an abrupt change based on a split second decision.
Obviously if death is imminent, making a last minute change of action won't hurt your chances of survival.
Oops, I guess the left props hit first. I was sitting in the back of the room and they only showed one picture of the gouges and they were on the right side, so I guess I didn't get the full story. I stand corrected .
But when you think about it, those first 12 prop strikes would have lasted only about 7/100 of a second if the engines were at 1,700 rpm. So, maybe with everything else going on she didn't know it happened?
I cannot tell you with certainty I could have done any better, but I hope so...
I can tell you from a lifetime of flying in the Great Lakes ice machine that I long ago decided the airplane is expendable...
If I am heavily iced - and I have been iced - these are my rules...
You carry insurance on the hull so you are not tempted to trade money for your life...
You make NO configuration changes when iced - or it WILL stall...
You descend by pushing forward on the yoke NOT by reducing power... And you land it on the belly (retractables) or the wheels, with the power on until you feel the ground, then yank the throttles and move the fuel selector(s) to cutoff...
If you do attempt to put the gear down do it only after you are at an altitude you would be willing to physically jump from the airplane... For me, that's about 3 feet...
Ignore the Controllers - they are not sitting there with you and they will make the wrong choices... I had a controller, on a black night over Lake Erie, insist that I MUST stay at 8000, when I was icing up like a Popsicle... I told her unable, and descended to warm air... Yes, she got an alarm on her radar - BFD...
So far, I have been lucky enough to avoid icing so heavy I would not dare lower the wheels as I crossed the numbers...
NASA has measured airframe icing rates as high as 1" per minute over the Great Lakes... That, of course, is not survivable in our GA tin cans unless you can belly it onto the ground right now...
