Narrative: After a turbulent approach in gusty weather; the landing performed by the flying pilot bounced three times. This caused severe damage to the fuselage. Main causes were probable fatigue; poor weather; and deferred items. The crew's duty day was extended the full two hours allowed due to passenger compliance complications in ZZZ. The weather was worse than forecast or originally reported; the worst winds reported by Tower were approximately 260 deg at 25G35. The deferred auto speedbrakes were very probably a contributing factor to the initial bounce; which led to two other porpoising bounces. Our scheduled duty day comprised of two; 5-hour flights with a 2-hour refueling stop in between. A schedule like this provides for very little sleeping breaks for the augmented crew; much less than a single long flight would allow. The use of duty time extensions on top of an already-long day should also be explored. Training involving a more thorough understanding of the effects of speedbrakes; particularly for heavy category aircraft; could be very beneficial going forward.


Second narrative: While on approach in ZZZZ; Tower reported turbulence over the threshold. While on the approach the winds increased from 19 kts up to gusting in the lower 30s. The approach was at one point a dot low on the glide slope but the PF (Pilot Flying) quickly corrected. Moderate turbulence was experienced on the approach. On touchdown the aircraft bounced and then bounced 3 times. At some point during the landing the aircraft fuselage was damaged. Deferred items- the auto speed brake was inoperative and the auto speed brake may have prevented the aircraft bouncing. Possible fatigue- the crew accepted a two hour extension in ZZZ due to passenger compliance. Weather- the turbulence over the runway in ZZZZ was not reported well and no intensity was given. Suggestions- A training session on use of the auto speed brakes and what to do when they are inoperative. Company review of extension policy and maybe some direction or advise from the union.


Synopsis: B767-300ER pilot crew reported damage to aircraft during landing due to inoperative aircraft systems; pilot fatigue and windy conditions.
