Narrative:

I was helping another mechanic by servicing the left engine oil. I svced the engine with 4 pints of oil and then closed the cap and access panel. I cleaned the oil access door with a rag of some oil I had spilled. After the work was completed the access panel was secured close to the best of my knowledge.
