Airport; Human Factors; Procedure
Training was in progress on the Local control position; I was the OJT Instructor and was conducting training. Aircraft Y was landing Runway 27 and Aircraft X was landing Runway 18. Aircraft Y touched down on Runway 27 and Aircraft X was short final for Runway 18. When Aircraft Y slowed to taxi speed I instructed the Trainee to tell Aircraft Y to hold short of Runway 18 as Aircraft X was short final and I observed the Aircraft Y was not going to roll through the intersection; but also was not going to be turned off the runway before Aircraft X crossed the Runway 18 threshold. The trainee instead gave Aircraft Y taxi instructions without any hold short instructions. The supervisor then instructed the CPC-IT to issue a go-around to Aircraft X. The trainee again gave taxi instructions to Aircraft Y as the pilot never responded to the initial taxi instructions. The pilot read back the taxi instructions; however Aircraft X had crossed the threshold and landed safely. This training session was a complex session with operations being conducted on crossing runways. The Trainee made a series of decisions that led to multiple go-arounds that eventually led to a runway incursion. I had recently been added to the training team of this Trainee and this was the first session I had trained this Trainee. I was asked to join the training team because of my patience. I was patient with this Trainee and allowed him to make a few mistakes that led to a couple initial go-arounds as I thought they were good learning experiences and the aircraft involved were training flights as well. In the incident that occurred; I allowed the Trainee to run a situation very close; however I don't believe I jeopardized safety as I instructed the Trainee to issue the crucial runway hold short instructions with enough time where if the pilot didn't respond; he could still issue a go-around to Aircraft X. Once the Trainee didn't give the instructions I told him to; the Supervisor stepped in and gave him instructions to issue a go-around. I discussed with this Trainee the importance of listening to your OJT Instructor and if you are told to give an instruction; you do just that.I know the other OJT Instructor on the team as well as the supervisor also discussed this with the Trainee. I recommend as an OJT Instructor I should have had better control of the situation. The turn of events from the giving the instruction to issue hold short instructions to the point where the regional jet crossed the runway threshold was only seconds long and the Trainee was given two chances to issue instructions to avoid a runway incursion but failed to do either. I now know to discuss these situations before they develop into something that cannot be fixed in time.
I was the Local Control trainee. I sent Aircraft Y around. Aircraft Y then made left closed traffic from Runway 27 with Aircraft X on a downwind to 4 mile left base for Runway 18. Aircraft Y was rolling out when issued his runway exit instructions but was not reading them back due to phase of flight. Aircraft X was approaching the approach end of Runway 18 at the time. It is believed Aircraft Y did not get his taxi instructions prior to Aircraft X reaching the approach end of Runway 18 therefore should have been sent around. Execute the backup plan earlier rather than let things play out.
A trainee was not taking action to separate aircraft utilizing intersecting runways. An aircraft was allowed to land with another aircraft occupying the intersecting runway.
