Today on takeoff from Leesburg Fl on a trip back to Ann Arbor MI the tower controller informed me that one of my landing gear was not retracted. Checked the indicator lights and sure enough the nose gear light was indicating down and locked- but the mains had retracted normally. I cycled the gear down at about 150 kts (3 green), then back up as I climbed out. Still nose gear down and locked…  Slowed to 125, my usual gear down speed, cycled the gear down, 3 green. Retracted gear, all three came up as usual.

Anyone had a problem like this before? I checked over the gear after landing and everything looks normal. Plan to put it on jacks and swing the gear before flying again but any ideas on this one would be appreciated.

We replaced the gas strut at annual in October, simply because it had been in use for about 10 years. We also replaced the hydraulic cylinder end and did the over center link mod per service bulletin SB074-0111. Did gear swing after that work, all fine. Have done about 15 landings since the October annual.
