Analysis

The left seat non-instrument pvt plt was being checked out in the flying club acft by a comm plt. The acft was being flown over Utah lake on a dark night, on final approach to runway 31 at the pvu arpt. While on final, the flying plt manuevered the acft for spacing from a second acft. A witness saw two acft over the lake. One aircraft was turning towards the airport when it went straight down. Post accident exam revealed acft contacted the water in a left wing, nose low attitude. The surrounding terrain to the northwest west and south provide no significant lighting that could be used for visual horizon reference.
