Two general aviation flight instructors reported a near miss during a training flight at a non-towered airport when one took off opposite direction.
Synopsis
Two general aviation flight instructors reported a near miss during a training flight at a non-towered airport when one took off opposite direction.
Narrative
My student and I were on a VFR practice approach (RNAV 15 to LPV minimums) at SPB. My student was wearing a view limiting device and I was acting as safety pilot. The incident occurred on our second practice approach at SPB and there were two other airplanes making practice approaches at the time with one being on an IFR flight plan. We were coordinating with Portland approach and receiving VFR traffic advisories and practice vectors for the approaches.On the incident approach; our change to the advisory frequency was approved by Portland on about a 10 mile final for runway 15 and we began making calls to the SPB CTAF. SPB is a busy airport and we often make early turnouts from practice approaches when there are conflicts with traffic in pattern. On this occasion; there were no apparent conflicts heard on the radio or seen on ADSB as we approached the airport. When we were on about a 2 mile final for runway 15; an aircraft on the ground announced that they were waiting to take off on runway 33 until the practice approach traffic was out of the way. I responded thank you and we will let you know when we are out of the way (i.e. when we initiate the missed approach). Shortly thereafter; when we were on about a 1 mile final for runway 15; an aircraft (hereafter 'departing aircraft') announced that they were departing runway 33 and that they had us in sight. I looked at the runway and saw the departing aircraft just leaving the runway and headed straight for us. I announced that we also had the departing traffic in sight and at the same time my student initiated the missed approach procedure (initiated a full power climb over the runway to 700') and I had to hold the yoke forward and pull the power back to prevent us from climbing into the departing airplane. The departing airplane climbed straight ahead without deviating to the left or right and passed about 100 feet over us. We initiated a climbing left turn and departed the area to the northeast.I do not know if the aircraft who called on the radio to say they were waiting for us to finish the approach is the same one that departed into us.About 1 hours after the incident; the owner and the chief pilot of the flight school that operates the departing aircraft called the flight school that I work at to talk with me. I was not there but the owner of my flight school took their number and I talked to them on the phone about 2 hours after the incident hoping to learn more about what happened at SPB. Neither the owner or the chief pilot who I talked to were in the departing airplane at SPB and neither one of them had talked to the instructor or student who were in the departing airplane when the incident occurred. They said they had heard about the incident from 'a third party' and were calling to learn more. I shared my account (as described here) but neither the chief pilot or the owner shared information or theories about contributing factors on their end. However; the chief pilot and flight school owner did confirm that the departing aircraft was taking off from a full stop; not a touch and go.
Second reporter narrative
Aircraft Y was doing a touch and go at Scappoose (SPB) and made radio calls (did not mention touch and go) on runway 33. Aircraft X was on the RNAV 15 at Scappoose (SPB) and also made radio calls (did not mention if they were going missed or going to break off early or take it down to minimums). The winds were 330 at 8kts; Aircraft Y assumed Aircraft X would break off the approach early; Aircraft X probably assumed Aircraft Y would make a full stop. Other airplanes were using runway 33. Both pilots expected something of each other but both did not meet each other's expectations. A tower at Scappoose (SPB) is very necessary for all the traffic it has there.
