Synopsis
General aviation flight crew reported while on the runway adding power to take off at a non-towered airport; an aircraft performing a go-around flew overhead them.
Narrative
I was operating at a non-towered GA airport where an extraordinarily high amount of traffic activity is often experienced. We pre-briefed our greatest threat for the entire flight as 'traffic issues and potential for mid-air collision'. After completing all pre-takeoff tasks; I was located at the hold short line of RWY 13 with a clear view of both the traffic pattern and runway environment. Along with another fully-qualified pilot; I observed several arrivals. We had no other distractions while we waited. We engaged on the intercom and compared our awareness of where each inbound aircraft was located and when we might depart. While observing a landing aircraft clear the runway; I estimated that the next inbound aircraft (single-engine low-wing) was on a greater-than two mile final with a perceived (normal) closure rate that would safely permit our departure. Entering the runway; I simultaneously announced our takeoff on CTAF. I immediately heard something unintelligible; followed by; 'Going around'. I was surprised to hear this call. I then heard another unintelligible transmission and; 'Do not take off. Do not take off'. Not knowing if this pilot was experiencing another issue; I complied; held my position; and did not add power. I attempted to look rearward; but the locked harness and canopy structure prevented a suitable view. I then witnessed a single-engine; low-wing aircraft pass directly over my aircraft at an altitude that appeared to be much lower than what one would expect from an aircraft well established in a go-around. I believe the aircraft's landing gear was retracted. I saw no attempt by this aircraft to offset laterally from the runway; as is often the custom. The CTAF was congested and I did not hear any other calls relating to this airplane. Once it was safe to proceed; I announced our takeoff and departed normally. The rest of the flight was conducted without incident. I am not aware of an error on my part; however; I have referenced the pertinent sections of the FAR/AIM; Airplane Flying Handbook; and AC 90-66C to ensure I am following current non-towered traffic pattern recommendations.
Second reporter narrative
I was the Rear-Seat Pilot (RSP) on an Aircraft X. We were number one at the hold short for Runway 13 at FFC for departure to ZZZ. An aircraft had just cleared Runway 13; and an Aircraft Y was observed on a base leg to Runway 13. The Front-Seat Pilot (FSP) and I both stated that we had adequate space to depart the runway. As the FSP taxied across the hold short and announced on CTAF our intention to make a takeoff; I referenced the Foreflight application on my iPad and noted that the Aircraft Y was greater than 2 miles from the threshold of Runway 13. I visually acquired the Aircraft Y; noted that he had turned on the final approach; and that we had adequate separation for departure.As the FSP increased engine speed in preparation for takeoff; I heard a garbled radio transmission stating; 'Do not Takeoff; do not Takeoff.' I was confused about who had made the transmission and was about to ask the FSP if he had traffic on the runway. I then heard the Aircraft Y transmit that he was going around. Turning in the seat to look to the rear; I visually acquired the Aircraft Y in the process of the go-around and passing overhead at 200-500 feet. I reported to the FSP that I had the Aircraft Y in sight and that he was performing a go-around.We departed with no further incident.
