In another era I couldn't get the gear down in a Baron while landing at Essendon. Long story but not here. Tried to wind it down but the handle would wind only three or four turns each way and then jam up. Turned out that was due to freight often being dumped over the winder and deforming it enough to make it jam. The hard plastic cover over the handle was cracked with age and freight on it. End result I cut my hand badly on the sharp plastic and bled a lot.
Finally got the gear down and wrote it up in the maintenance release. Got the DCM for all that but had the satisifaction of bleeding all over the maintenance release. As usual the MR had no recorded defects on it before that flight (SOP in GA) but after I finished with it the blood and pen entry were mixed with each other and another MR needed..
