Narrative:
On landing runway 22 lga XA50Z, 3/wed/88, widebody transport X wingtip missed medium large transport Y's tail, right side of runway about 15-30'. Parked on north side runway 22 taxiway G. Medium large transport Y faced to north on taxiway G with little concern if his tail was clear of the runway. Sideline of runway 150' wide and widebody transport wing span 155', not a very good operation. Callback conversation with reporter revealed the following: widebody transport flight crew did not see the medium large transport holding near the runway until they were already on the runway and slow enough to not be able to go around. Captain was able to quickly ascertain that they would not hit the other aircraft but would come very close. Captain's estimate of the miss distance was between 10 and 20'. After arriving at the gate, the captain telephoned the tower and spoke to a supervisor. Supervisor admitted that the tower controller knew it would be close, but felt there was nothing he could do. Just before the widebody transport touched down, the captain heard the tower controller address the medium large transport in question with 'move on up.' that was landing captain's first clue there might be something amiss. The measurements involved in this incident provide a picture of just how close the widebody transport's wingtip was as it passed the vertical stabilizer of the medium large transport. The runway is 150' wide, the wingspan of the widebody transport is 155', 4' and the distance from the edge of runway 22 to the edge of taxiway a is approximately 115'. The length of the medium large transport is 147'. This computes to a miss distance of less than 10'.

Title: LNDG ACR-WDB'S WINGTIP NEARLY HIT TAIL OF ACR-MLG HOLDING TOO CLOSE TO RWY.
Narrative: ON LNDG RWY 22 LGA XA50Z, 3/WED/88, WDB X WINGTIP MISSED MLG Y'S TAIL, RIGHT SIDE OF RWY ABOUT 15-30'. PARKED ON N SIDE RWY 22 TXWY G. MLG Y FACED TO N ON TXWY G WITH LITTLE CONCERN IF HIS TAIL WAS CLR OF THE RWY. SIDELINE OF RWY 150' WIDE AND WDB WING SPAN 155', NOT A VERY GOOD OPERATION. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: WDB FLT CREW DID NOT SEE THE MLG HOLDING NEAR THE RWY UNTIL THEY WERE ALREADY ON THE RWY AND SLOW ENOUGH TO NOT BE ABLE TO GO AROUND. CAPT WAS ABLE TO QUICKLY ASCERTAIN THAT THEY WOULD NOT HIT THE OTHER ACFT BUT WOULD COME VERY CLOSE. CAPT'S ESTIMATE OF THE MISS DISTANCE WAS BTWN 10 AND 20'. AFTER ARRIVING AT THE GATE, THE CAPT TELEPHONED THE TWR AND SPOKE TO A SUPVR. SUPVR ADMITTED THAT THE TWR CTLR KNEW IT WOULD BE CLOSE, BUT FELT THERE WAS NOTHING HE COULD DO. JUST BEFORE THE WDB TOUCHED DOWN, THE CAPT HEARD THE TWR CTLR ADDRESS THE MLG IN QUESTION WITH 'MOVE ON UP.' THAT WAS LNDG CAPT'S FIRST CLUE THERE MIGHT BE SOMETHING AMISS. THE MEASUREMENTS INVOLVED IN THIS INCIDENT PROVIDE A PICTURE OF JUST HOW CLOSE THE WDB'S WINGTIP WAS AS IT PASSED THE VERT STAB OF THE MLG. THE RWY IS 150' WIDE, THE WINGSPAN OF THE WDB IS 155', 4' AND THE DISTANCE FROM THE EDGE OF RWY 22 TO THE EDGE OF TXWY A IS APPROX 115'. THE LENGTH OF THE MLG IS 147'. THIS COMPUTES TO A MISS DISTANCE OF LESS THAN 10'.
