1.3.72. ... the pilots wore their helmets throughout the walkaround. BK-18's pilot noticed the undercarriage pins were still installed, removed them and handed them to the see-off team.
1.4.42. ... the see-off13 team was cleaning the canopy as the pilot arrived at BK-18. The pilot then conducted a walkaround of the aircraft, electing to remove the undercarriage pins in the process.
I am not familiar with F35 see-off procedures but would the pilot have expected to see undercarriage pins still in as he did his walk round? Should they have been already removed at that point?
