The Federal Aviation Administration (FAA) defines a runway incursion as:

“A runway incursion is any occurrence on an airport runway involving an aircraft, vehicle, person, or object on the ground that creates a collision hazard or results in a loss of separation with an aircraft taking off, intending to take off, landing, or intending to land.”


The following incident occurred at 03:49 UTC on July 29th, 2007, at Philadelphia International Airport, involving two aircraft, AWI3973 and USA1752.

AWI3973 was a Canadair Regional Jet CRJ-200/L bound for Cincinnati (KCVG).
USA1752 was a Boeing 757-200/J inbound from Las Vegas (KLAS).

The weather at the time of the incident is as follows:

KPHL 300254Z 04003KT 9SM FEW050 SCT140 OVC250 22/20 A2997 RMK AO2 SLP149 T02220200 53013

The runway configuration being used at the time was landing runway 09L and departing runway 09R.

A diagram depicting the incident is provided to accompany the audio clip.

The audio clip of the Philadelphia tower frequency contains many but not all of the transmissions made during this event.

The clip begins as the tower controller instructs SWA2570 to execute a missed approach:

135.100
[00:19]   SWA1242 is cleared to land on runway 9R

[00:23]   USA1752 calls the tower to verify the initial taxi instructions (not included in the clip)

[00:46]   RPA3246 (“Brickyard”) is cleared to land on runway 9R

At the same time on the other tower frequency 118.500, another tower controller working departures, clears AWI3973 for takeoff on runway 9L (not included in the clip). As AWI3973 begins their takeoff roll, USA1752 crosses runway 9L without clearance to do so.

[00:53]   The tower controller on 135.100 is alerted to incursion

At the same time, the controller on the other tower frequency 118.500, instructs the departing AWI3973 to abort takeoff (not included in the clip).

118.500
[01:19]   The tower controller issues taxi instructions for AWI3973 to taxi back to runway 9L for departure

[01:44]   End of clip.



This clip exemplifies the importance of understanding taxi instructions and specifically runway crossing instructions. It seems clear in this case that the pilot of USA1752 is at fault, and should have noticed on the airport diagram that taxiway Sierra is at no point located north of runway 09L-27R. The controller repeated the taxi instructions a total of 3 times (only 2 of which are included in the clip).

Just shows how much you need to pay attention. The pilot of USA1752 wasn't even listening when the controller gave the instructions. He asked for clearance to cross and assumed he would get the answer he wanted. Especially for a pilot that should know his way around that airport. He probably flies into there more than most of the other pilots out there.

Beautiful work getting the diagrams and clips together. That pilot is sure going to feel like an idiot if he ever hears back that tape, claiming he was "specifically cleared to cross"...

I don't think that the taxi instructions to go right N, left S could have been much clearer either...he even repeated it I think.  Bravo to tower for catching the wrong turn so quickly.

With those communications between the controller and pilot, the pilot was either *completely* distracted during the initial exchange or he was outright lying on the latter part of this clip.  Given the fact that all ATC communications are officially recorded (not at all considering LiveATC's archive here), I can't possibly believe that this pilot felt his recollection of the exchange would stand.

We probably won't remember to check, but in the US controllers and pilots have the ability to report various safety issues at the   Aviation Safety Reporting System (ASRS, or sometimes referred to as the NASA report).  The online database of incidents is here and this incident reported in the pilot's words might appear over the next few months:

That is a great site, thanks for that. I was looking to see if there was a report of the incursion this month at La Guardia, but nothing yet.

Very nice aevins. Great audio and I liked the use of the airport diagram. I was very helpful in visualizing the situation.

Thought that controller was gonna have an [MOD: controller name removed] moment there and rightfully so. The contollers were on their game as they are all the time and averted what could have been an ugly scene.  I guess its hard to understand how the crew messed that up. The controller not only gave them a right turn but followed it up with a compass direction. Glad the chain of events was broken by the controllers.

Yea, great job with all the info. But it looks like you reversed the positions. Local West 135.1 would have been the position that cleared those guys to land on 9R and told the USA the taxi instructions and Local East 118.5 would have been working those 9L departures. It was pretty intense Sunday night, I don't think I've ever seen that many aircraft lined up on Kilo or on the AOA at one time period! Like 25 stretched from Spot 2 by Kilo 5 all the way down to Spot 10 or 11 at Hotel. Then another 5 on Papa, 10 on Sierra, 5 on Juliet, a few on Whiskey. It was quite intense.
