PA32 ON APCH BEHIND A DEPARTING P2V FIRE BOMBER VERY HVY; ENCOUNTERED WAKE TURB AT FLARE AND INITIATED A GAR; NEARLY LOSING CTL. THOUGHT XWIND WOULD DISSIPATE THE WAKE OF THE DEPARTING NEPTUNE.

Narrative

1) VOICE FROM NEPTUNE TAXIING OUT (ON CTAF) 'REALLY HVY; LONG TKOF.' 2) WIND STRONG AND GUSTY; SLIGHT R XCOMPONENT. 3) PA32 ENTERED WIDE R BASE; ANOTHER FIRE BOMBER INBOUND BEHIND US. 4) NEPTUNE AND ITS SHADOW STILL RIGHT TOGETHER APPROX 1 MI OUT. 5) JUST AS WE FLARED; SUDDEN ROLL TO L. DESPITE HARD R RUDDER AND AILERON; WE FLEW OFF TO L; BARELY MISSING A RWY DISTANCE REMAINING SIGN. WENT AROUND AND LANDED OK. ANALYSIS -- CHAIN OF EVENTS: LONG; TIRING; SLOW VFR FLT TO CDC FROM ROCK SPRINGS; WY. 40 KT DME HEADWIND; TURB. WANTED TO BE ON THE GND. FUEL STATE NEAR LEGAL RESERVE; ABOUT 1 HR. BOMBER AHEAD VERY HVY; ANOTHER ONE INBOUND BEHIND US. THOUGHT TBC WOULD DISPERSE WAKE. WRONG DECISION! OBVIOUSLY THE NEPTUNE'S R WING VORTEX DRIFTED TO RWY CTR AND CAUGHT US JUST AS WE FLARED. CORRECTIVE ACTION: WAS PROPER BUT BARELY SUCCEEDED. FULL R AILERON AND RUDDER; FULL PWR. FORTUNATELY WE HAD ONLY 1/2 (25 DEGS) FLAPS AND EXTRA SPD; BUT OUR L WING STILL CAME PERILOUSLY CLOSE TO HITTING THAT RWY DISTANCE MARKER. AFFECTING FACTORS: WAKE VORTEX EXTENDED FOR MI; DESPITE STRONG AND VERY TURBULENT SURFACE WIND. NEPTUNE WAS STILL ONLY ABOUT 500 FT AGL WHEN 2+ MI AHEAD OF US. DATA: A FLT SVC SPECIALIST WAS OUT OBSERVING WX AND SAW THE INCIDENT. COMMENTED STRONGLY.
