Synopsis
Tecnam P2006 instructors reported while performing maneuvers the right engine failed because of possible low oil pressure. A safe return was accomplished.
Narrative
Upon departing from ZZZ we climbed to 4500 MSL and started heading to the northwest area from ZZZ. We did clearing turns and pre-maneuver checks with steep turns afterward. Upon completion of steep turns; we noticed that oil pressure was reading lower than usual. It was still in the yellow and all other instruments were in normal operations so we decided to keep monitoring it and keep things close to our home airport. After completion of another maneuver; our right engine suddenly gave out. I took control and we were roughly 8-10 miles away from ZZZ at 4500 MSL. I ran the engine outflow and instructed my co-pilot to read out the engine securing and restart checklist. After running the engine restart checklist to the point where we tried to restart the engine; the engine would not start or even move; it was completely still. We were able to enter the downwind for Runway XX and made radio calls letting everyone know about our situation on the CTAF asking people to please stay out of the way and that we had lost our right engine. Thankfully we were the only airplanes at the airport in the air at that time. We were able to successfully land the plane safely and taxi off of the runway. At no point did we ever declare an emergency since we were so close/high up and had a very easy time (per the situation) getting to ZZZ and landing. Thorough pre-flight was conducted and we checked all items such as oil; fuel etc. Engine runup was normal as well so I am unsure as to what caused the right engine to stop working.
Second reporter narrative
During a rental checkout flight the right engine had a sudden engine failure at 4500 ft. MSL. During the flight we noticed the right engine had low oil pressure. Continued to monitor and it eventually dropped below the yellow arc. All other engine gauges appeared to be within normal operating conditions. The engine suddenly stopped and from the left seat did not appear to be windmilling. The Multi-engine Instructor (MEI) took controls and completed the emergency checklist items. After completing the engine failure and restart checklist the right engine did not restart. The MEI then established a 10nm 45-degree downwind entry into Runway XX at ZZZ. A single engine pattern and landing was completed safely. I did not notice or feel any engine roughness during run-up. Also did not notice any leakage of oil or fuel during pre and post flight inspections. Fuel was topped off prior to departure and was visually inspected as well. Oil was also inspected visually and was within normal operating levels. I am unsure of what caused this failure.
