A Strange Observation..........

**rankin3** · 01-09-2003, 05:52 PM

Here is the NTSB report on the USAir Flight 1016 the DC-9.

July 2, 1994
USAir Flight 1016, a DC-9 traveling from Columbia, South Carolina, to Charlotte, North Carolina, crashed in Charlotte, killing 26 people.

Investigation status: Closed

An NTSB report blamed the crash on the flight crew's decision to land during a violent thunderstorm, which was producing powerful downward winds called wind shear.

i was up flying today with my instructor and we were talkin about what caused to crash. he had heard it was a messed up elevator. so we decided to try a little experiment. and 3000 ft. and full power we brought the nose up until the aircraft stalled as it stalled as many of you may know one of the wings has to roll over. it will naturally roll to the left because of the tork or the engine. anyway we brought the airplane to a stall the left wing dropped and we had to recover so it wouldnt roll on its back. in my opinion the exact thing happened. the elevator was faulty and it deflected up all the way. this cause the airplane to shoot up in the sky like a rocket until it stalled. the left wing fell over and the pilots werent able to recover before the aircraft had rolled over on its belly. that aircraft not being particularly good at flying upside down did an inverted dive straight into the ground. i think that would explain everything

As much as I hate to think about it, it seem the flight recorder says the same things.
Should that be the case, the lady could have done nothing but bet she tried everything possable.

What type of airplane did you do that in? If you kept the airplane coordinated during the stall, the airplane should break the stall straight ahead with little or no wing drop, this is even true in a turn. Un-coordinated, the airplane will drop a wing as one wing stalls before the other (This is how spins develop). The B1900 situation sounds more complex than a departure stall, more along the lines of a Vmc roll; considering the airplane's ground track and reported engine failure. Whether it was due to the aircraft or the crew I hesitate to guess, either way is jsut as tragic.

it was a C152. yes i agree the stall should have been broken straight down usually. sometimes i've had that not to happen though. if enough speed is lost the aircraft has a very good chance of dropping a wing and rolling over. inverted at that altitude there wasnt much they could do. wind could have played a big part in flipping the plane over. a slight right crosswind would have helped it out alot

The emergency that bites you is seldom the ones you train for. Usually on takeoff you are primed for things like the engine/s to sputter, gear retract failure, etc not control system failure. Even if the crew reacted instantly and had enough trim to get the nose down assuming they had any control it would have taken too long to recover.

Not all light planes stall with the same characteristics as the 152. Yes, power on stalls no matter how well you coordinate them tend to fall off on one wing, usually the left. The Piper Cherokee also doesn't need to be pitched up to such a dramatic deck angle and just sorta sigh and drop forward when the stall brakes.
It would be logical that turboprops all have slightly different stall habits.

It even happens at cruise altitude as happened to a crew on a flight from Mexico to Seattle when they had a problem with controlling the horizontal stabilizer. Although very well trained and help from ground maint, they could do nothing and it got to the point that the aircraft controlled the flight crew.

My point is that the 152 was rolling inverted. Power on or off, as long as they are flow coordinated they won't do this. The airplane may break left as it stalls, but it won't roll inverted. That rolling is a sign that the airplane is not being flown coordinated the entire time during the manuever. An uncoordinated stall results in a spin entry, which if held will roll almost inverted as the pitch comes down. I do agree that airplanes have seperate stall characteristics, even within the same types. That's why we see washout, stall strips, stick pushers...all that good stuff.
