Narrative:
Landing runway 14R ord. ATIS wind 190 degrees, 18 KTS. Three mi behind large transport. Wind given on final, 180 degrees, 13 KTS. I was copilot flying a heavy transport on a stable approach. Threshold was xed at 50' AGL on speed of 140 KTS (reference was 137 KTS). Control inputs negated all crosswind drift and aircraft was aligned with centerline of runway. A normal flare was begun at 20'. Just prior to T/D the right wing dropped abruptly causing the #4 engine to contact the runway. The landing and rollout were normal. Inspection by maintenance revealed damage to the frangible drain mast and minor damage to the underside of the cowling (abrasion). No damage to the engine. Supplemental information from acn 85056: large transport had landed 1 min prior to us and I think we encountered his vortex.

Title: ACR HVT LOSS OF ACFT CTL DURING LNDG FLARE. RIGHT OUTBOARD ENGINE POD HIT RWY.
Narrative: LNDG RWY 14R ORD. ATIS WIND 190 DEGS, 18 KTS. THREE MI BEHIND LGT. WIND GIVEN ON FINAL, 180 DEGS, 13 KTS. I WAS COPLT FLYING A HVT ON A STABLE APCH. THRESHOLD WAS XED AT 50' AGL ON SPD OF 140 KTS (REF WAS 137 KTS). CTL INPUTS NEGATED ALL XWIND DRIFT AND ACFT WAS ALIGNED WITH CENTERLINE OF RWY. A NORMAL FLARE WAS BEGUN AT 20'. JUST PRIOR TO T/D THE RIGHT WING DROPPED ABRUPTLY CAUSING THE #4 ENG TO CONTACT THE RWY. THE LNDG AND ROLLOUT WERE NORMAL. INSPECTION BY MAINT REVEALED DAMAGE TO THE FRANGIBLE DRAIN MAST AND MINOR DAMAGE TO THE UNDERSIDE OF THE COWLING (ABRASION). NO DAMAGE TO THE ENG. SUPPLEMENTAL INFO FROM ACN 85056: LGT HAD LANDED 1 MIN PRIOR TO US AND I THINK WE ENCOUNTERED HIS VORTEX.
