Rented clapped out C152, relying on the ceiling mounted speaker because no headset, three hour flight into Ann Arbor Michigan. Very tired. Permission to land, so did so, and taxied back to cross the end of the runway to fuel up and park. Brain dead by this time, I didn't hear/or understand that ATC had told me to hold short for a landing aircraft. However always have a good lookout, I saw the approaching aircraft and judged plenty of time to scoot across and get out of its way.
At the fuel depot I was informed that ATC wanted a word....
I apologised, told them I didn't have a headset and hadn't absorbed the hold short instruction, but that I had a jolly good lookout before crossing...and after a strict telling off was forgiven and decided hence to always fly with a headset.
But I still always have a jolly good lookout no matter what ATC tells me, you never know, do you?
