B-747 Collision With Airbridge Follows Apparent Brake Failure 4 pages. [PDF 77K]
Passenger behavior — described by the chief cabin attendant as a ‘riot’ prompted by observations of wing-tank fuel venting — complicated the flight crew’s return to the gate in response to a failed engine instrument. Failure to manually connect an auxiliary hydraulic pump rendered the aircraft brake system inoperative for taxi.
Audit of ATC Operational Errors Prompts Call for Mandatory Remedial Training 4 pages. [PDF 71K]
The U.S. Department of Transportation investigated whether optional training has been effective in reducing operational errors by air traffic controllers. Auditors recommended a policy of mandatory training — without connotations of punishment — when relatively serious operational errors occur.
New Strategies Prevent ATC Clearances for Operation on Closed Runways 6 pages. [PDF 108K]
In a few recent runway incursions, aircraft crews obtained an inadvertent clearance from air traffic controllers to take off or to land on a closed runway. Solutions have included revised procedures, improved communication and reevaluation of some memory aids.
Human Error Causes Outages in Airway Facilities 6 pages. [PDF 149K]
To prevent personnel-induced equipment outages, operations managers see opportunities to improve communication and coordination, address procedural problems and avoid issues caused by the introduction of new software or equipment.
Reviewing U.S. injuries/fatalities, air carrier data and international airport surveys, a study by the U.S. Federal Aviation Administration found an industry consensus favoring comprehensive apron-safety programs at airports. Conspicuity of workers often was not a factor in accidents.
The Australian Transport Safety Bureau said that, among other factors, air traffic controllers did not advise the flight crew — nor did the crew request — details about the lateral limits, direction of travel and groundspeed of a thunderstorm approaching the destination airport.
