Narrative:

Approach to ILS runway 27 bos normal and stable. Current ATIS almost 1 hour old, reported overcast skies, gusty winds. When we passed the final fix, we found scattered clouds and were given a steady-state left crosswind report by tower (approximately 240 degrees/20 KTS). No gust, shear, or turbulence reports. The new student first officer was PF. I (the instructor/captain) was the PNF. At 500 ft AGL, I gave the company required call for speed and sink, bug +7 KTS, sink 700 ft. Then I reminded the first officer of our target EPR for our weight (maximum landing) and suggested he not reduce power too much if the airspeed got just a little fast. About 100 ft AGL, I remind him 'don't pull the power off until we're on the ground' and made the 100 ft call. Just before he began to flare, I saw the airspeed drop and I pushed the power in slightly. Then as he began to flare, we sunk rapidly and I pushed the throttles way up and increased the pitch attitude. We touched down firmly and bounced as I called 'I've got it.' the right wing dropped and apparently touched the ground before my control inputs could regain wings level. The subsequent rollout and turn-off were normal. I don't know if it was windshear, a gust, wake turbulence, water-land thermal, or what. I do believe the tower could have provided us with better/more current WX at the final fix.

Title: MLG CREW CONTACTED WINGTIP ON RWY DURING LNDG.

Narrative: APCH TO ILS RWY 27 BOS NORMAL AND STABLE. CURRENT ATIS ALMOST 1 HR OLD, RPTED OVCST SKIES, GUSTY WINDS. WHEN WE PASSED THE FINAL FIX, WE FOUND SCATTERED CLOUDS AND WERE GIVEN A STEADY-STATE L XWIND RPT BY TWR (APPROX 240 DEGS/20 KTS). NO GUST, SHEAR, OR TURB RPTS. THE NEW STUDENT FO WAS PF. I (THE INSTRUCTOR/CAPT) WAS THE PNF. AT 500 FT AGL, I GAVE THE COMPANY REQUIRED CALL FOR SPD AND SINK, BUG +7 KTS, SINK 700 FT. THEN I REMINDED THE FO OF OUR TARGET EPR FOR OUR WT (MAX LNDG) AND SUGGESTED HE NOT REDUCE PWR TOO MUCH IF THE AIRSPD GOT JUST A LITTLE FAST. ABOUT 100 FT AGL, I REMIND HIM 'DON'T PULL THE PWR OFF UNTIL WE'RE ON THE GND' AND MADE THE 100 FT CALL. JUST BEFORE HE BEGAN TO FLARE, I SAW THE AIRSPD DROP AND I PUSHED THE PWR IN SLIGHTLY. THEN AS HE BEGAN TO FLARE, WE SUNK RAPIDLY AND I PUSHED THE THROTTLES WAY UP AND INCREASED THE PITCH ATTITUDE. WE TOUCHED DOWN FIRMLY AND BOUNCED AS I CALLED 'I'VE GOT IT.' THE R WING DROPPED AND APPARENTLY TOUCHED THE GND BEFORE MY CTL INPUTS COULD REGAIN WINGS LEVEL. THE SUBSEQUENT ROLLOUT AND TURN-OFF WERE NORMAL. I DON'T KNOW IF IT WAS WINDSHEAR, A GUST, WAKE TURB, WATER-LAND THERMAL, OR WHAT. I DO BELIEVE THE TWR COULD HAVE PROVIDED US WITH BETTER/MORE CURRENT WX AT THE FINAL FIX.
