Slightly low on the approach. Normal Approach The other side
Historical Section, the ever popular approach to the now closed Kai Tak Rwy 13 in Hong Kong.
“While some of those photos are obviously botched approaches and landings,
several are actually S.O.P. (standard operating procedure). The 747 is built to withstand landings
where the actual touchdown occurs at as much as a 45 degree crab angle.
This is because the wing mounted engines only allow a very small amount of bank angle at
touchdown to prevent an engine strike. So, 747 pilots must us the “crab method” of crosswind correction
all the way through touchdown, instead of the more landing gear friendly “wing low method.”
Boeing tested this theory in 45 knot direct crosswinds with no damage to the aircraft or its landing gear.”

At the end of the roll out the fire services contacted the Captain by VHF and asked if he had a problem as they had seen sparks from the #4 engine. The captain replied that he had no problems and that he would taxi to the parking bay. He noticed that the engine oil quantity was decreasing on #4 and shut it down. On arrival at the parking bay a visual inspection of the engine revealed significant scrapping of the fan cowls at the 6o’clock position, deformation of the fan case at 6o’clock and damage to the thrust reverser cowls at 6o’clock. Upon opening the reverser cowls the bottom of the main gearbox was found
severely cracked, (thus explaining the oil loss), as was the angle gearbox. An engine change was declared and the engine was changed approximately 3 days latter. The Captain was quite surprised at the extent of the damage, as he thought the landing was reasonably normal!
