Oh yeah man, the saga goes on ... :-I ----------------------------------------------------------------------- AVflash Vol. 4, Issue 41 Monday, October 12, 1998 ----------------------------------------------------------------------- MORE 737 INSPECTIONS PROPOSED -- BULKHEAD CRACKS TARGETED: The latest reaction to the ongoing challenge of what to do about aging aircraft came last week as the FAA proposed to require that high-cycle Boeing 737s be inspected for cracks in their forward pressure bulkheads. The FAA said its proposed AD was based on reports of fatigue cracking in the structures, although no accidents are known to have occurred. _________________________________________ The Air Bulletin Vol. 3 No. 1 October 7, 1998 FAA ORDERS CHECKS ON YOUNGER 737s The Federal Aviation Administration (FAA) is expanding checks of the world's most numerous airliner to include Boeing 737-100 through 500 series jets with between 20,000 and 30,000 flight hours. Airlines were given 60 days to look for damaged insulation on wires going to the fuel boost pumps through conduits buried in the wing tanks. All previous FAA orders related to the problem applied to 737s with more than 30,000 flight hours. FAA spokeswoman Alison Duquette said the threshold was lowered after some signs of wire damage were noticed on aircraft with between 29,000 and 35,000 flight hours. In May 1998, the FAA grounded all first generation 737s with more than 50,000 flight hours for urgent checks, fearing a spark could touch off an explosion or start a fire [The Air Bulletin Vol. 2 No. 33]. The order was progressively extended, albeit with less urgency, to aircraft with lesser flight hours. The order will affect an estimated 215 US registered 737s. Though it is not mandatory for non-US registered aircraft, the order is likely to be followed by airlines outside the US for safety reasons. The FAA and Boeing engineers believe engine vibration over many thousands of hours shakes the wire in the conduit until a protective Teflon sleeve and insulation wear through. The FAA is asking airlines to replace any damaged wires if necessary and apply a second wrapping of Teflon. Newer generation Boeing 737s, the - 600, -700 and -800 series have not been affected as they do not have electrical wires running through conduits in the fuel tanks. -- - CW - "What a waste it is to lose one's mind.
