Two airplanes were taxiing at the airport in Knoxville, Tennessee, when a ground collision occurred.
According to the pilot of the Cessna 172, he was taxiing towards the run-up area, when he saw the engine start of a Cessna 150. He said it was stationary in a parking spot facing the taxiway as he proceeded forward.
As he continued to taxi, he saw the right wing of the Cessna 150 pass under his wing toward his airplane. As he tried to avoid a collision, the right wing tip collided with the windscreen.

During the collision the right aileron of the Cessna 150 sustained substantial damage.
According to the pilot of the Cessna 150, he was preparing to exit the ramp area and taxi to Runway 08. After making a radio call, he checked the taxiway for other aircraft, and said his sight was limited due to an airplane that was parked next to him.

He said that he checked to see if any airplanes were on the taxiway and did not see any.
He pulled out onto the taxiway and felt a slight bump when the Cessna 172 struck his airplane from behind.
Probable Cause: The pilot of the Cessna 150’s failure to avoid the taxiing Cessna 172.

All of you “aces” going at this report like rabid dogs piss me off. Yeah, they messed up, but you “holier than thou” folks need a little humility. I suspect you’re lucky if you fly 25 hours a year.
ALL pilots are required to make ABSOLUTELY sure that the area in front of their aircraft is clear before moving. I blame the instructor for not drilling this into the 150 pilot’s head. Was this incident reported to the FAA?
Well…
The pilot of the Cessna 150 …that ran into the other aircraft …was a CFI.
Yes, the FAA is informed & involved.
Even though the NTSB fills the role of “Investigator in Charge”, the FAA always provides an “Additional Participating Person” (at a minimum) as part of the accident investigation team.
What’s the deal with TN people not knowing how to fly or taxi? Too soon?
Don’t know the details in this case, but I’ve seen IPads stuck on glareshields and windows/windshields in many airplanes nowadays that would totally block the view of conflicting traffic in the air or on the ground.
It’s getting stupid how many pilots are obstructing their outside vision with cameras, IPads, and other devices. Many just for a social media click.
Proves you can’t fix stupid.
This is the kind of thing that finally convinced me to stop flying. I saw too many stupid, careless accidents and near-accidents and thought ‘it’s a good thing this didn’t happen while flying’. I had a partner who made a habit of flying IFR before he even thought about getting an instrument rating. His rationale was that the sky is big enough for everyone, so why worry? He did everyone a big favor by running out of gas, crashed and died.
Aircraft from the right has the right of way. The 172 was the aircraft in movement from the right. The 150 pilot is both in error and at fault. Mistakes happen.
This one is easy to both grasp and identify where the fault and mistake are.
Wait … On the runway, as the title says, or on the taxiway, as everything seems to indicate? Do they tie down planes in Knoxville to the runway edge lights?
Taxiway. Sorry about that. Headline has been updated. Thanks for reading.
To be expected; there is some finger-pointing. They both mention sun glare as a factor, but disagree as to how much impact (pun intended) it had.
Other than that; it looks like we’ve wrung this one out. Looking forward to tomorrow’s…
One of the most important lessons in aviation and plain!driving.
SEE and BE SEEN!!
Yes that’s what I tell my daughter .. just because the light is green and you got right of way look anyway .. lol don’t forget you have wings either and not in a car .. yes that’s why God gave us eyes .. so many traffic accidents could be avoided if people would look for themselves .. so tower said clear that means look both ways before crossing the runway anyway … Lol live and learn ..
here to throw in my 2 cents.. they did not collide on a runway
Right you are. Headline has been fixed. Thanks for reading GAN.
Hard to visualize something like this can actually happen, but it happens way too often. Both Pilots should have been looking around… Especially while moving… While moving on the ground, there is not one good reason to look down… With the Flight Instructor in at least one of the planes, this should have never happened.
Basically an auto accident … with one driver pulling out in front of the other. How many times have we heard this story? Same issues at play.
Title of this article should have read Two general aviation aircraft collided while taxiing. As it was written I thought two pilots had walked into each other. LOL
Right you are Lynn. Headline has been corrected. Thanks for reading GAN.
Another stupid pilot trick. The 172 plowed into the 150 from behind. Yes, the 150 should not have pulled in front of the 172 on the taxiway but how does the 172 not see another aircraft IN FRONT of them and then simply apply the brakes? Heads down adjusting iPad and GTNs I suspect. If you are looking outside you can’t miss an aircraft in front of you. How long does it take to move at 3kts from the parking spot to being on the taxiway When taxing at 10kts how long does it take to stop…almost instantly. I don’t think he saw the aircraft he was overtaking until the wing came through the windscreen. Don’t have your head down while taxiing. See and avoid. Old concepts that are known but still not consistently applied.
There is absolutely no excuse for this!
Better start an investigation, find why Cessna aircraft can’t avoid each other,
Typical taxiway/traffic pattern chaos, ironically by the same people that say this is the way you should do it.
“Cessna pilots collide on runway?” That sounds a lot worse than colliding on the taxiway, which is what actually happened. Click bait?
No. Just a badly written headline, which has been updated. Thanks for reading GAN.
If you weren’t there don’t guess what two so called pilots should know exactly there responsibility is when operating a aircraft .did they have license to fly and who lost it because someone could have died and if they can bump on the ground don’t let them fly.
Radio???
What do you say? Hey Cessna 150, look out!!
Like driving a very fragile and expensive car……pay f_____g ATTENTION!
Seems like the trainer was letting the student pilot practice and made up an excuse to protect the student.
What happened to ‘See and avoid’ ?
The older instructor in the C150 should have been looking multiple times for traffic.
The very low time [ 121 and 6 hrs in type], in the C172, got a big surprise, probably expecting the C150 to wait for him to pass.
I radio call to the C150 might have prevented the crash.?!
Don’t simply see an obstruction be it an airplane, tractor, car or truck. See it it’s moving.
Humans were not meant to fly and God is punishing our hubris
No excuse for this The pilot of the 150 said he was unable to see because of another aircraft. If that was the case, he had no right to move his aircraft. It may have been necessary for him to shut down his aircraft, get out and push it to where he has visibility.
When I taught automobile driving, one of 18-21
Tasks the student was required to perform
Was coming out of a quiet street and making a turn onto a busy roadway where student had limited visibility due to obstructions[ truck,bushes]. Several students would pull up 10 inches, stop; pull up 10 inches stop; pull up 7 inches ,stop ( repeat if necessary- to get clear line of sight down the road
One of these people should never have a driver license, oh wait a minute *** are we talking about some nut who drives a plane!?×?
Excellent observation and exactly what should have happened, but I suspect that if the 150 pilot was moving slow and paying attention this incident wouldn’t have happened. Likewise, if the 172 pilot was looking he would have seen the 150 pulling in front of him and had plenty of time to stop.
Mistakes happen, thankfully no one is hurt.
This is no different than common traffic in automobiles.
Verify by looking, then execute your move.
Lack of verification causes many accidents.
Why didn’t the pilot in the 150 part call out on the frequency to see if there was anybody taxing down the taxiway first and then secondly why didn’t the 150 pull forward just a little bit to where he could see if there was anybody taxing down the taxiway, instead of blaming that he could not see because there’s a plane next to him part blocking his line of down the taxiway. Lame excuse they could’ve got somebody hurt lame excuse if you can’t see pull forward just a little bit and stop and look very simple. I’ve been in a lot of small planes myself Thousands of hours right seat as an observer it’s very simple forward to where you can see past any obstructions if you want to stay alive keep your eyes out of that window looking around and use your radios. Make a call very simple folks.
A call wasn’t necessary. Clearly at fault, not spotting the 172 on the taxiway. My guess is he didn’t even look.
There is a rather clear difference between a runway and a taxiway.
Try telling Harrison Ford that!
All that could be said is be visable and keep the eyes open and hope the other person is looking for you.
