The 777 manual leaves it to the crew to report a hard landing , so the aircraft will trigger a report which we have automatically downlinked to MCC. If the crew dont report it then it didnt happen......... Think its down to the operator as if the report is triggered it means it has landed hard. The Airbus 330/340 tells you to do an inspection if the report is triggerred. Guess this is only an issue if you're going to a transit station with no LAE present !! Seen a few on both types but have never found any evidence of damage on inspection . Only bad one i've seen was an unreported one on a 757 a few years ago which caused a fuel leak on spar line of inboard wing , when QAR was read it was hard and overweight . The giveaway was movement of 'pins' on undercarriage withe sealant and paint cracked where everything had moved !!
