The airline im with has a very very high rate of hard landing events showing up on the QAR for the 737-800.This is not the case on my fleet, 767/757.Maybe an experience issue.However the other evening going in to HKG, nil wind nice WX etc, I had no reason to have any doubts about the FOs landing ability.I have 11,000 hours of IP time on type including base training etc.At 50 feet things looked good, I was already thinking of the turnoff options.At 20 feet nothing was happening with the flare activities, but my guard was certainly down.As is my custom from lots of instructing my left hand quietly slid to close to the control column.What happened next took me by surprise, and I believe but cant be sure, that the FO actually lowered the nose slightly, however the flare did not take place, and it was too late for me to save the very hard arrival.I had no choice but to comment in the Logbook "suspected hard landing.....".The FO was grounded for re-training as a result.My question is this.Have any of you experienced a technically defi ned hard landing and if so, what does it feel like, because this is a first for me in 36 years of flying heavy jets.The QAR said a g force of 1
for my event.
