Ground collision - 3 x RJ
WAFB Channel 9, Baton Rouge, LA |Three planes collide on the ground at Baton Rouge Metro Airport
No injuries, but somebody probably looking for a new job. |
I am of course no expert and its wise to wait until an investigation has been made before making any conclusion but.......
If the engineer pressed a starter switch in the cockpit shouldn't she of checked to make sure that both throttle levers are in the "idle" position before doing anything? Correct me if i am wrong but the only way to start an engine is via the cockpit! Unless of course the thrust levers were at idle and there was some sort of mechanical problem which caused the aircraft to move forward but only time & the NTSB will tell! :ugh: |
I'm interested to know how you can get a jet, presumably starting from off, to takeoff power that quickly. I know they are smaller engines, but what's the spool-up time? The NTSB report on this one ought to be interesting to read...

Maybe she should have checked the thrust levers were closed, but better not to comment too early. They may have been jerked open by a fall, manual dropping whatever. Maybe it was a dreadful mistake in starting with thrust lever wide open, but you must learn we all make mistakes in our jobs at sometime. A whole industry is built around trapping those errors so they become harmless. This was an unusual procedure, starting up in a hangar. Mistakes are part of life, that is why there are rubbers on the end of pencils (OK then, erasers to you Americans!). One hopes the young mechanic is treated with sympathy- can you imagine how she feels?
Now you made a serious grammatical error in your post. Work on that and trap that error before back to school time! With many jets, the engine must spool up to idle before thrust position is recognised. From idle to full power for a CRJ- a few seconds. Brakes probably off as in hangar- movement very rapidly. By the time realisation happened, it would probably be too late to stop immediately. |
Good post Rainboe. How many of us have made subtle mistakes that, on reflection, could have ended in bitter tears. Most times you're able to make a mental note to self and learn for next time.
I hope she gets the opportunity not to make the same mistake again. |
Hello,
Just a little bit puzzled. No blame intended. Photos gone so can not say if this was a 1/2 or 7/900. Because if it was a 100/200 you can not just start the engine. You would have to arm the ignition, engage the starter and open the thrust leaver and advance power. Opening the thrust leaver from shut off to Idle requires one to lift the guard move the TL to idle then release the guard before one can advance the TL. I do not expect somebody to do these actions just for drymotoring. On the 7/900 series you do ot need to arm the ignition but still have to open the thrust leaver from shut off to idle. The 1/200 series require quite some thrust increase for break away power single engine, even more so the 7/9. There for the article does not make any sence. But whatever happend I hope she is treated fairly! Regards Micky |
Micky,
Aggressor was a 701, victims both 200s. N706EV into N916EV and N975EV, two reportedly w/o but doesn't say which. |
The mechanic will be lauded by a hero by the company and a bum by the insurance company.

There is a slightly less hysterical item in Flightglobal.

Write-offs? Nonsense! Bit of sheet aluminium and a pop rivet kit and they're away! Well, JADEC doesn't believe so....... "N706EV and N916EV are likely to be declared a total loss." |
Lesson To Be Had For All Mechanics (pics) � Tech Ops Forum | Airliners.net
Lots of pictures here... "706 was suppose to be getting a compressor wash. Somehow the left engine throttle was at max power, Igniter breakers were not pulled, and the hydraulics were not on and brakes were bled down, and finally the torque links were not connected.. With this in mind put someone in the cockpit untrained and no reason to be in there, to turn over the engines for a compressor wash. The young lady pushed the button for the right engine, then when time completed stopped it, she pushed the start button for the left... Since it has a FADEC when the conditions were met the engine spooled up and it lit off, in 3 seconds it was at 85% and jumping the chalks. 5 seconds later it was over. I had two aircraft to inspect that night. Only one left that morning Setting - 975 had been in the night before and was swapped out and sent back. On my walk around at the gate I found a flat spot on the tires. So with an LC1 and nose tires, the lead decided to nose the aircraft in. That put 975, 45 feet in front of 706 and closer to the hanger. A/C 916 was backed into tail dock for throttle gearbox inspections. Chain of events. A cleaner was three feet forward of the pax door on 975, across from him starting the process of changing the nose tires was a new mechanic. Two other cleaners were inside of 975 as well as one mechanic. 975's lead was at the lead desk as well as one mechanic. On 706, Lead mechanic xxxxxx told xxxxxx to do the cockpit part of comp wash even with reservations. xxxx a new mechanic was sent to operate the cart. The remaining two crew members were sent to trouble shoot Duct Mon under wing. The inspector for 706 like myself had more than one a/c to inspect and was in the office as well as acting supervisor. On 916 there was a mechanic on each engine doing gearbox inspection. The third mechanic was doing LC-2 check inspections. Acting lead xxxx xxx When 706 engines started to get loud, I looked up and saw it jump the chalks.xxxx xxx questioned himself why was the engine so loud for the start of a comp wash. xxxx the mechanic running the cart ran away noting that his shirt felt like he was going to be sucked into the engine. The two mechanics under the wing hearing the engine, thought that was not right and ran towards the ditch off to the right. When 706 started moving xxx (the Cleaner) and the mechanic starting to change the nose tires dived forward and away of 975. Willy was missed by 975 by a mere 5 inches. 706s pax door made first contact with 975 winglet underside violently throwing it into the air. The wing came down on 706's fuselage at the point connection is painted on the side where it snapped into two pieces. 706's wing was pushed below 975's wing and made contact with it's gear and lodged in place. The forward momentum, the down force on the left wing on 706 and Inertia caused by the lock between 706's wing and 975 gear caused a 90 degree turn by 706 in which the nose and the right main temporarily came off the ground. The nose was high enough that the pax door was sheered off by a Tug that was still attached to 916. 706 stopped because its nose made contact with 916 nose. 3/4 way through its 90 degree turn 706 left engine started ingesting 975 winglet and was FODing out. 706 came to rest sitting on top of the large tug. 975 with first contact was pushed back about five feet. The locking of its gear to 706's wing made 975 also to do a 90 degree turn also. This was when willy was just missed. This action also pushed 975 onto its tail shattering it. 916 contact with 706 at the nose in a down ward movement, snapped 916 drag brace and caused the tail go into the air and pierce itself on the tail stand. This movement threw xxxx xxx out of the aft equipment bay. It is hard to believe that it took all of five seconds after 706 jumped the chalks for all of this to occur and not Kill anyone. If 975 had not been where it was..706 left wing would have clipped the hanger. That with the left engine at max there would have been an explosion at the least. With 916 being in the hanger on that side we would have lost the hanger as well as many people." |
Cor !!!!! :eek::eek::eek:
It sort of reminds me of that hilarious story of the bricklayer..."on the way down I unfortunately met the brick carrier coming back up"" I'm sure that somebody out there will be able to name the raconteur. :D |

:hmm: I believe aeroplanes go inside hangars!

took some time but I finally got back the ''famous'' photos, erased on almost every english speaking internet site :
french version, alas Cajun CRJ salad, help yourself ! WWW.CRASH-AERIEN.COM :: Voir le sujet - CRJ' salad ; don't press the red button, miss...trop tard |
Found the pictures on a Macedonian forum.

Thanks CS, it was late (for me) last night when I wrote my former p*st and the grey cells wern't up to par.
"The Bricklayer's Story by Gerard Hoffnung" always had me in stitches !!:ok: Love your 'handle' btw. !! f |

Maybe if they had used chocks instead of chalks, this whole thing wouldn't have happened :hmm:
