An air carrier B727 flight crew entered a discrepancy into the maintenance logbook and later the captain decided that the entry was not warranted and he lined through it and indicated that it was 'entered in error.' the flight crew now thinks that this technique is in error.

Narrative:
After takeoff, I detected a faint musty, moldy smell in the cabin air. From my experience, this smell comes from the water separator filters in the air cycle machines being dirty and in need of a routine cleaning. This smell is commonly called a 'dirty sock smell.' during cruise flight, I directed a write-up in the logbook be made, and maintenance be told. During the rest of the cruise, descent and approach, I could no longer detect the smell and decided the write- up was not a valid one. After landing, I lined through the write-up and wrote 'write-up entered in error.' I submit this NASA report because I've been told that only a mechanic can clear any write-up and I cannot delete one.

FROM MY EXPERIENCE, THIS SMELL COMES FROM THE WATER SEPARATOR FILTERS IN THE AIR CYCLE MACHINES BEING DIRTY AND IN NEED OF A ROUTINE CLEANING. THIS SMELL IS COMMONLY CALLED A 'DIRTY SOCK SMELL.' DURING CRUISE FLT, I DIRECTED A WRITE-UP IN THE LOGBOOK BE MADE, AND MAINT BE TOLD. DURING THE REST OF THE CRUISE, DSCNT AND APCH, I COULD NO LONGER DETECT THE SMELL AND DECIDED THE WRITE- UP WAS NOT A VALID ONE. AFTER LNDG, I LINED THROUGH THE WRITE-UP AND WROTE 'WRITE-UP ENTERED IN ERROR.' I SUBMIT THIS NASA RPT BECAUSE I'VE BEEN TOLD THAT ONLY A MECH CAN CLR ANY WRITE-UP AND I CANNOT DELETE ONE.
