Incident: Porter DH8D at Halifax on Nov 16th 2012, runway incursion

By Simon Hradecky, created Tuesday, Nov 27th 2012 20:50Z, last updated Tuesday, Nov 27th 2012 20:50Z

A Porter Airlines de Havilland Dash 8-400, registration C-GLQD performing flight PD-256 from Halifax,NS to Ottawa,ON (Canada), was taxiing for departure from runway 32 and had been cleared to taxi along taxiway D hold short of runway 05. The aircraft however continued to cross runway 05, while another Porter Airlines Dash 8-400, registration C-GKQA performing flight PD-241 from Ottawa,ON to Halifax,NS, was on final approach to runway 05. Flight 241 continued the approach, was re-cleared to land on runway 05 after flight 256 had vacated the runway, and landed safely. Flight 256 departed shortly afterwards and reached Ottawa safely and on time.

The Canadian TSB reported that the runway incursion occurred in the aftermath of a confusion because taxiway B had been renamed to taxiway M. The crew had intended to depart runway 32 from taxiway B. Following resulting discussions the crew requested a full length departure from runway 32 and was cleared to proceed to the end of the taxiway which the crew interpreted as a clearance to cross runway 05 as well.

It's all good, Porter has an SMS, so everything will be just fine (insert rolling eyes here).

I wonder how the risk assessment will look when the review the fact that one of their aircraft cut in front of another of their aircraft in the late stages of the approach? Will they address the root cause, which is that their onboard library updating process is apparently ineffective, or will they just issue another ops bulletin telling pilots to "be careful"???

@Acaboy

You are right. They were told to hold short of runway 05. They must have missed it and didn't pay attention.

Preoccupied?

It appears that the crew had a copy of the 30JUN11 chart instead of the 15NOV12 chart(in effect one day before the incident). On the new chart Taxiway B has been relocated to the western end of runway 05 between A and C, this presumably due to the lengthening of runway 05/23 from 8800 to 10500 feet. The former taxiway B at the eastern end of runway 14/32 has been renamed taxiway M on the new chart. However, they did receive a very straightforward instruction from Ground Control to taxi along D and HOLD SHORT of runway 05! FYI, the terminal is the spiky looking building with the rotating beacon star on top.

If you are cleared to taxi to the end of a taxiway and there is an intersecting runway, you must ask for clearance to cross that runway unless told to do so already.

This is one of the questions in the PSTAR exam every private pilot in Canada must take before flying solo.

The crew should have been more careful and asked if they are cleared to cross.

Changing RWY name criteria
By Stefano on Wednesday, Nov 28th 2012 10:01Z

Wich are the criteria followed in changing the RWY name ?

Shouldn't be better, when a new TWY is built, using the last following letter already used instead of changing the place of an already existing designation ?

Not clear to me

They were cleared to taxy along TWY D, so whatever you choose to enter RWY 32 thru twy B (or M) or at twy D end, you always have to cross RWY 05/23 and comply with the hold short instruction.

Not clear to me how the taxiway name change is related to the RWY incursion
