Aircraft
1.5 hours into this flight; flying survey points over south east [state] in Aircraft X; the right engine stopped producing power at 9;138 ft. MSL. Indications were a 'shuddering' of the aircraft as the right engine windmilled. I looked down and saw that manifold pressure and RPMs were dropping on the right engine; as was EGT. I held directional control of the aircraft; pushed mixture; prop; and throttle levers full forward and turned on the boost fuel pumps. No change in the right engine. I looked down and saw that cylinder temperature remained at 380 degrees; oil pressure remained (prop was wind-milling); and oil temp remained at around two notches below maximum (normal). I handed my operator the check-list; and had him read off 'Loss Of Power In-Flight' checklist while I performed the steps. No change. I had him read off the 'Restart Engine In-Flight' checklist while I performed the steps; the engine did not re-start. I had him read-off the 'Secure Engine In-Flight' checklist while I performed the steps.While performing the 'Secure Engine In-Flight' checklist; I contacted ATC to inform that I had an engine failure and that I was returning to ZZZ. I also [advised ATC]; that two souls were onboard and approximately 2 hours fuel remained. We started a slow descent into ZZZ.At about 9 miles out from ZZZ; I contacted Tower and told them that I was going to land on Runway XX (down-wind runway) and that I was [advising ATC] I had my operator read off the 'Single Engine Landing' Checklist; and landed uneventfully on Runway XX; with enough momentum to taxi off the runway and not close the airport. Following shut-down; the FBO tugged Aircraft X to the ramp.Post-flight inspection did not reveal any excess oil in the nacell; nor fuel pooling inside or streaks out. There were still 9 qts (hot engine) in the right engine; and fuel level in the right tanks were 3/4 tank in the inboard and 1/2 tank in the outboard. Fuel pressure was satisfactory on the ground post-flight.
PA-31 pilot reported and engine failure that appears to have been well handled by the pilot through the use of CRM.
