a Beech1900 which was flight planned from Saint John via V310 to the Fredericton VOR departed at Saint John at 1057Z. The aircraft was cleared off Runway 32 & proceeded north bound as if proceeding direct the YFC VOR instead of on the airway. The aircraft was then given a heading to intercept V310 but ended up going through the airway and eventually cleared direct FRENN. The 1100Z weather for Fredericton was winds calm visibility 15 ceiling 1100 overcast. GGN7482
was cleared to CYFC
airport for the straight in VOR Runway 27 approach and switched to the Fredericton FSS. A few minutes later the FSS called the sector and advised that GGN7482
was unable to continue with the VOR 27 approach. The aircraft was then cleared for an ILS15
approach. The aircraft was later observed proceeding West-Bound west of the Fredericton airport at 3,000' in intermittent radar coverage. GGN7482
then came over to 124.3 requesting vectors. The controller advised unable vectors because of radar coverage west of the Fredericton airport and was cleared direct the FC NDB. The intermittent target appeared to be still preceding West-Bound 25 west of Fredericton airport still at 3,000'. It soon became apparent the flight needed assistance and was given a Clearance to climb and vectored for an ILS15
landed in Fredericton at 1136Z for a total flight time of 39 minutes. The pilot informed Moncton Low Supervisor he believes he had a problem with his VOR. He apologized for the confusion but offered little explanation as to why he did not proceed for the ILS 15 when cleared through FC FSS or why he proceeded so far west after breaking off the approach to Runway 27. No other aircraft were involved and separation was not compromised.
