Actually the design is fine.
The problem is centered around the steering potentiometer, hence the new plackard in the airplane. The part is manufactured in some where other than Brasil.
Maybe it's just me but isn't the
STEERING potentiometer PART of the
STEERING system!?
I had the exact same thing happen to me while I was based in BOS on the ERJ. Early morning departure out of HPN (white plains, NY). Right at Vr the airplane gave a little "wiggle" about the vertical access. Hardly noticeable. We wrote it off as being a gust of wind or some jet blast. The flight went without incident until the nosewheel hit the pavement of runway 27 in BOS. Once the nosewheel hit the plane suddenly and violently veered to the right swinging to a 45-60 degree angle to the side of the runway. CA (FP) simultaneously slammed on the left brake, throgh the left engine into full reverse, and brought power up on the right engine. I was along for the ride. I watched as we rapidly approached the snow bank on the side of the runway and I actually braced myself for impact. I saw the runway lights right out the windshield. Luckily, it was the captains leg. The captain had been with eagle forever, and was one of the first RJ captains at Eagle, he was also an IOE check-airmen/instructor, in short, he had thousands of hours on the ERJ. I had finished IOE but had not yet completed consolidation, so I was reallly new to the jet. Anyway, we had to get company to tow us back to the gate, we both thought that we had cleaned out some runway side lights so we had Massport check. Surprisingly, all the lights were still in tack and their was no damage to the plane. The next morning with a different plane we landed in BOS with 2 inces of snow on the runway with BRA reported as "FAIR". We were incredibly lucky.
There have been several other incidents at Eage with aircraft experiencing similar problems only in less critical times. A LGA crew had the same thing happen on the taxi-out and had to get towed back.
I have always wondered (I am no longer on the ERJ) if their were any symptoms (other than the wiggle) that were ignored by crews/mx prior to the incident. Weird vibrations, I notice on taxi in that some ERJ wheels are twitchier than others, i've always attributed it to technique, but maybe not.
Anyway, fly safe, keep your finger near the disconnect, and remember that it ain't over until you're getting into your seat on the Logan Express Shuttle.
