Aircraft Equipment Problem Critical; Ground Event / Encounter Ground Strike - Aircraft
At touchdown; aircraft started to pull right and right wing started to drop. I heard a noise and thought I had blown a tire. Next I flew back to centerline and in doing so I may have added slight power. I slapped the gear handle. I never heard a Gear Warning tone. When the Crew was asked; they said they didn't either.Settling down again; I kept the wings level and anticipated what I thought might be the inevitable right tendency.The aircraft however remained level; but I informed tower I had an issue and would roll out to the end. I appeared to have good control; and the noise was gone. I elected to taxi the short distance to the FBO with an escort of Airport Operations vehicles.By shutdown; all indications appeared to be normal again until post-flight inspection. At post-flight; damage was observed to the prop; the flap cowlings (subsequently the flap linkages); and rear avionics antennas.The approach to landing felt normal. I was sequenced between two aircraft and behind another Pilatus. Flaps were extended 7-8 miles from the airport and gear was extended on a final vector to the FAF approximately abeam the FAF. Landing checklist was completed via the IPAD; and a 'Last Finals' check was performed by myself at 500 foot call. (Last Finals: gear down-three green; flaps 15- final setting; lights on; landing clearance; go-around altitude set). Yaw Damper (YD) was disconnected at DH announcement.On GP for the ILS; Torque was normal at 6-7 inches with the AOA indicating middle or slightly lower. Idle power was set between 70-50 AGL. Initial touchdown was at TDZ or slightly beyond.ATC was typical for the airport and time of day.Maintenance and company management are investigating. And I have been reviewing my actions and performance in this event.
Pilot reported that at touchdown the aircraft pulled to the right and the right wing started to drop; however; the wings remained level during rollout. At postflight; damage was found to parts of the aircraft.
