Captain reported receiving possible false GPWS alerts while on final approach and during initial climb at F82 resulting in two go around procedures. The Captain landed safely after receiving the alerts and determined them to be a possible GPWS database issue.

Narrative

On our approach and departure at F82 today; we got erroneous GPWS alerts. We executed 2 GPWS escape procedure go-arounds. We then determined that the GPWS was not recognizing the new runway and arrival and departure path. We ended up having to disable the GPWS terrain warning for our arrival. The first approach we got the 1st warning approximately 2 miles north of the airport in the vicinity of high tension power lines. This prompted the first go-around / escape procedure. On the second approach we flew a steeper approach path to give more clearance on 3 sets of power lines. We got the terrain pull up again on 1/2-3/4 mile final. This prompted the second go-around / escape procedure. There are also numerous high towers to the north and west of the approach path. These are well charted on the LBB RNAV (RNP) Z 17R approach chart. Specifically the missed approach course shows these well. There are a set power lines at the threshold for Runway 17 that have been buried underground. Perpendicular to the threshold is also a dirt farm road that had truck traffic on it. On the ground the GPWS map shows Amber for the airport sitting on the ramp. Like the airport does not even exist. It thought we were in a dirt field. This caused a caution terrain amber GPWS alert right after rotation on departure. I spoke to the lineman about the GPWS issue. He said some others have also had the issue. I asked about an advisory NOTAM and he said he can add one. He also informed me the GPWS and approaches are supposed to be updated in the next database revisions. The aircraft FMS database and company database appeared to have correct information. The runway length and company visual depiction matches the actual pavement. The taxiway turnoffs from the runway are narrow and require caution; but are safe.There is also construction on the parallel taxiway north of the FBO. This is abeam a hangar with a 200 ft ramp that can be used to get around it. This was briefed to us by the ground personnel at the airport. Clearance can be obtained by calling Ft. Worth. Suggestions: The MFD (multi-function flight display) display is on the ground showing Amber. A couple of the others show the buried power lines and how close the farm road is to the threshold. This information should be added to the notes ASAP. With the nuances; until the GPWS is updated; maybe there should be a verbal briefing before flying into this airport.
