Pilots of two aircraft reported a near miss with each other while approaching a non-towered airport.
Synopsis
Pilots of two aircraft reported a near miss with each other while approaching a non-towered airport.
Narrative
Departing from ZZZ1; we requested VFR flight following ZZZ1-ZZZ. ZZZ1 ground did not issue the flight following request; instead instructed that we would remain with ZZZ1 tower for traffic advisories. On departure from ZZZ1; tower provided multiple visual traffic advisories ahead of us; then while still in the ZZZ1 Delta swapped us to ZZZ CTAF. Approx. 8 mi N of ZZZ1 at 2500 ft there was a plane South and 500 feet above us; descending on to us. We made multiple CTAF position reports as well as calling the tail number of the aircraft descending on us. They did not respond. When the plane was within 100 feet we took evasive action for a 90 degree right turn. A few moments after the near miss; the plane (Aircraft Y) made their first CTAF call; unaware of the near miss in the VMC 10+ visibility conditions. Aircraft Y explained over the CTAF that they were on with ZZZ approach conducting the VOR practice approach and never received any traffic warning that they were going to collide with us. We were flying a Cessna 172. The plane that was a near miss was a Cessna 172.
Second reporter narrative
On Day 0 at ZZZ airport; we were flying an airplane.The airplane in front of us thought we were much closer than we were.And claimed we were on top of them.I believe they had their ADS-B. ON A VERY WIDE RANGE.WHICH MADE US APPEAR CLOSER THAN WE WERE. That other airplane made a very quick turn to the right and came up behind us. There was no TCAS alert or evasive action.This felt very uncomfortable and the confusion was unintentional.However; no harm came from it. We looked at the ADS-B reports. We listened to the Tower frequency. We listened to the approach frequency. All is well; and we were never too close to the plane in front of us. The reason we're making a safety report is because we believe we could've monitored. The CTAF further out; and we could've informed that aircraft; we were further out than then thought we were. Even if we're getting vectors and traffic calls from approach or center. I think it would help all of us if our planes avionics are capable to monitor CTAF as soon as possible; even if we're talking to Tower or center or approach on another frequency; whilst they are giving us vectors and traffic advisories. Thank you for your time and consideration and for making the airways safer every day.
