"Aircraft and Ramp Security Issues" with Baggage

The approaching holiday season will bring hoards of passengers to airports, and a blizzard of flights to domestic and foreign destinations. Air crews will want to heed the experiences with aircraft and ramp security offered by several ASRS reporters. Our first reporter, an air carrier Captain, describes what happened at a foreign location when the passenger and bag count didn’t match:

Cabin Kinks

Another incident reported to ASRS points to the value of clear communication between the cabin crew and flight deck when passengers are observed behaving strangely–whether or not they have yet created problems.

Wave Off

Late-boarding, panicky passengers are a headache for every gate agent–and a potential security problem, too. The moral of this Captain’s story: "Always question if in doubt; some passengers will do anything to catch a flight."

Views from the Greasy SideASRS is receiving more and improved information from maintenance personnel since the issuance of customized reporting forms for this community in 1997. From "creative" repairs to troubling trends, here are highlights from some recent maintenance reports.

Pull Handle and Flush

ASRS’s resident maintenance guru tells us there are several approved methods in the maintenance manual for interim repair of cockpit window pressure leaks. None include toilet paper in the materials required.

Caps OffA study of return-land incidents to be published later this fall in ASRS's Directline publication found that more than one third of the study incidents involved pre-departure errors by ground personnel and flight crews, or pre-existing equipment problems. The next maintenance report highlights a typical cause of a return-land event:

Hitch-hiking Spacers

ASRS has recently received a rash of maintenance reports describing technicians’ failures to install spacers (a type of washer) when changing wheel assemblies. The absence of this small part causes excessive bearing wear and tire "wobble." In some of these incidents it appears that the spacers themselves are hitchhikers–in grease:

Use of work cards, which provide step-by-step instructions for routine parts installations, can help technicians detect when spacers have gone AWOL.

When CFIs Fly Together

This excellent report from a CFI involved in a loss-of-separation incident at an uncontrolled field describes some of the crew coordination issues at stake–and potential hazards–when two CFIs fly together.
