Narrative:

I was performing my duties as flight engineer aboard a flight on jan/sat/96. The first officer was flying the approach into dfw, we were landing to the north with winds out of the northwest at approximately 300 degrees at 15 KTS gusting to 25 KTS. The landing was firm, but in no way unsafe. The captain did not request a hard landing report, and no entry was made in the aircraft logbook. A post flight inspection was accomplished by myself, and resulted in the finding of several oxygen masks had fallen from the passenger service units in the cabin. A visual inspection was performed on each mask, and it was verified that the valve actuator pin was still installed and that no flow of oxygen was found. I checked the oxygen pressure indicator on the flight engineer panel to see if there was a drop in pressure and none was noticed. I was not aware that this type of mask deployment required an entry in the logbook. I thought this was necessary only when the masks were deployed in one of three ways: automatically -- when the cabin altitude reaches 14000 ft, electrically -- by positioning the oxygen system switch to the on position, and mechanically -- by pulling the manual actuation and reset handle to on. After reading my manuals and the basic knowledge I have of the oxygen system, I felt that it was okay for me to repack the masks into the passenger service units and not make a logbook entry, due to the type of deployment and the number of masks that had fallen (4). I apologize for my actions and was not aware that my failure to enter this incident in the logbook was in violation of company and FAA regulations.

Title: THE RPTR REPACKED 4 OXYGEN MASKS AND CLOSED THE PAX SVC UNIT DOOR WITHOUT LOGGING THE ACTIVITY IN THE LOGBOOK. RPTR LATER FOUND A LOGBOOK WRITE-UP WAS REQUIRED. RPTR STATED THE LNDG WAS FIRM BUT NO WAY UNSAFE.

Narrative: I WAS PERFORMING MY DUTIES AS FE ABOARD A FLT ON JAN/SAT/96. THE FO WAS FLYING THE APCH INTO DFW, WE WERE LNDG TO THE N WITH WINDS OUT OF THE NW AT APPROX 300 DEGS AT 15 KTS GUSTING TO 25 KTS. THE LNDG WAS FIRM, BUT IN NO WAY UNSAFE. THE CAPT DID NOT REQUEST A HARD LNDG RPT, AND NO ENTRY WAS MADE IN THE ACFT LOGBOOK. A POST FLT INSPECTION WAS ACCOMPLISHED BY MYSELF, AND RESULTED IN THE FINDING OF SEVERAL OXYGEN MASKS HAD FALLEN FROM THE PAX SVC UNITS IN THE CABIN. A VISUAL INSPECTION WAS PERFORMED ON EACH MASK, AND IT WAS VERIFIED THAT THE VALVE ACTUATOR PIN WAS STILL INSTALLED AND THAT NO FLOW OF OXYGEN WAS FOUND. I CHKED THE OXYGEN PRESSURE INDICATOR ON THE FE PANEL TO SEE IF THERE WAS A DROP IN PRESSURE AND NONE WAS NOTICED. I WAS NOT AWARE THAT THIS TYPE OF MASK DEPLOYMENT REQUIRED AN ENTRY IN THE LOGBOOK. I THOUGHT THIS WAS NECESSARY ONLY WHEN THE MASKS WERE DEPLOYED IN ONE OF THREE WAYS: AUTOMATICALLY -- WHEN THE CABIN ALT REACHES 14000 FT, ELECTRICALLY -- BY POSITIONING THE OXYGEN SYS SWITCH TO THE ON POS, AND MECHANICALLY -- BY PULLING THE MANUAL ACTUATION AND RESET HANDLE TO ON. AFTER READING MY MANUALS AND THE BASIC KNOWLEDGE I HAVE OF THE OXYGEN SYS, I FELT THAT IT WAS OKAY FOR ME TO REPACK THE MASKS INTO THE PAX SVC UNITS AND NOT MAKE A LOGBOOK ENTRY, DUE TO THE TYPE OF DEPLOYMENT AND THE NUMBER OF MASKS THAT HAD FALLEN (4). I APOLOGIZE FOR MY ACTIONS AND WAS NOT AWARE THAT MY FAILURE TO ENTER THIS INCIDENT IN THE LOGBOOK WAS IN VIOLATION OF COMPANY AND FAA REGS.
