General Maintenance Action
Human Factors; Logbook Entry; Procedure
I was on duty; day pilot; [at] ZZZ1. I was asked to stay in service and fly to ZZZ to complete a maintenance flight; ROC (Rotorcraft Operational Check); on Aircraft X. The aircraft needed the ROC for main rotor rpm in autorotation. The aircraft was supposed to be 100% finished with all maintenance and ready for me to fly upon arrival at ZZZ. I arrived at ZZZ and first briefed with the mechanics on the work that had been done and what we needed to do. I did a preflight of the aircraft. After the preflight I went over the logbook with the mechanic; the aircraft had all the maintenance completed and the last thing it needed was the ROC. I used [software program] on the iPad for weight and balance and a flight release. We flew the aircraft; it was within limits on the ROC; completed the flight; documented the ROC and I left. Yesterday I was informed by Name that the aircraft had been weighed and the weight and balance was not correct and did not match what was documented in [the software program].I made the assumption the aircraft was in compliance and did not verify the weight and balance in the RFM (Rotorcraft Flight Manual). I was on duty; it had been a busy day. In the future it would probably better to have a pilot dedicated to the maintenance task and not on flight duty. For myself I need to go over all documents to verify compliance.
Helicopter pilot reported not verifying the weight and balance information in the aircraft manual prior to flight and flew the aircraft in a non-airworthy condition.
