| 12.31:00 | COP: | Take action. Emergency checklist... Engine and propeller engine oil pressure low ... 15B |
| 12.31:16 | COP: | 15B... engine oil pressure low, engine oil and prop oil pressure ... checked. Well, engine oil pressure uh, that is this one, this one is slightly lower than the other one, but... |
| 12.31:32 | COP: | It's decreasing. |
| 12.31:33 | CPT: | Yes.. |
| 12.31:34 | COP: | Yes, it's decreasing. |
| 12.31:37 | COP: | If only prop oil pressure, apply uh ... uh .. if only prop oil pressure low, apply propeller oil pressure low procedure, well... that is not the case... |
| 12.31:43 | COP: | Then next... engine oil pressure control warning panel light on ... or, engine oil pressure below thirty psi. |
| 12.31:54 | CPT: | That is not the case. |
| 12.31:57 | CPT: | But it is still normally in the green, that is what's so strange. |
| 12.31:59 | COP: | That's funny, isn't it?. |
| 12.32:00 | CPT: | Yes. |
| 12.32:01 | COP: | It is decreasing uh ... [captain's first name] engine oil pressure light on, or .... |
| 12.32:12 | CPT: | Yes, but we are not going to continue with this... |
| 12.32:13 | COP: | No, no, no, no, no, engine oil pressure..., well light or below thrity psi, that is not the case. So of two things ... if so, than you may continue, but if they are both on, so if the light os on and the pressure is below thrity psi, then it must be shut down. |
| 12.32:33 | CPT: | OK. |
| 12.32:37 | CPT: | Well, what do we have? It is an, above fifty?. |

| 12.32:42 | CPT: | And we... [set] the warning pressure is .... |
| 12.32:43 | COP: | Yes, the light is on. So the light is on, or below thirty, well.... |
| 12.32:50 | CPT: | Continue normal operation. |
| 12.32:51 | COP: | Yes. |
| .... | .... | .... |
| 12.42:21 | COP: | I also think, that because you are flying in flight idle, that because of that you have less problems than you might have had otherwise.. |
