| April 19 Final Rule FR Doc 04-8539 AD 2004-08-04 Fuel system safety |
Douglas-built MD-11 airplanes. Requires inspections to detect and correct damage to tail fuel tank pipe assembly to prevent fuel leakage and possible ignition. |
Effective May 24. Apparent design/manufacturing defect. Federal Aviation Administration (FAA) airworthiness directive (AD) mandates compliance with manufacturer's alert service bulletin (SB). Affects 60 airplanes in U.S. registry. |
| April 19 Final Rule FR Doc 04-8544 AD 2004-08-09 Powerplant system safety |
Airbus A300-600 and A310 series airplanes. Requires inspections and modifications to prevent jamming of throttle control cable(s). |
Effective May 24. FAA action mandates compliance with numerous Airbus SBs. Optional terminating action cost is estimated at $20,000. No airplanes in U.S. service, but don't import one without this work having been done. |
| April 22, 2004 Notice of Proposed Rulemaking (NPRM) FR Doc 04-9111 Docket No. 2003-NM-211-AD Emergency equipment safety |
Airbus A330 and A340 airplanes. Requires inspection of slide raft valves and modification of discrepant valves to prevent failure of an emergency slide raft to deploy and inflate during an emergency, which could impede evacuation. |
Comments due May 24. FAA action follows that of France's Direction G�n�rale de l'Aviation Civile (DGAC), which reports the problem may exist on all A330s and A340s. Failure of regulator valve to activate when the exit door is opened, which renders the slide unusable. Airbus has issued various all operators telexes (AOTs). Action affects 14 A330s in U.S. registry, involving 13 work hours per slide, and eight slides per airplane. Not trivial. |
