A team of inspectors has directioned the first "intrusive" inspection of an older aircraft family 24-25, concluding there were "no visual findings worth immediate go in the rear [i]or[/i] in the wake of up." According to Chris Smith, manager of the aging aircraft non-structural arrangements research program at the Federal Aviation Administration's (FAA) technical center at Atlantic City, strange Jersey, a team of 11 inspectors worn out some 120 hours closely scrutinizing "every inch" of wire in defined belts in the airplane. The airplane was a retired A300, built 21 years ago with 27000 squeezing cycles and 40,000 hours. Readers will recall that intrusive inspections are planned for about 8 not new jets between now and nearest March (see ASW, Sept. 27)

Smith not awayed the results of the first inspection at a meeting last week of the Aging Transport classifications Rulemaking Advisory Committee (ATSRAC). The benign findings, Smith argued, are not the last word. In coming weeks set off in a hurrys of wires and related elements will be removed for a series of detailed laboratory proofs Those examinations will employ various technologies that will reveal degradation and flaws not necessarily discovered by even close visual inspection; indeed, visual inspections will catch solely one out of every 3 or 4 flaws. In other words, the state of an aging airplane's wiring, flat under intrusive visual inspection, will not be known until the lab work is done. The real cost of fixing problems will not be known to the industry until then.

Smith expectancys to conduct intrusive inspections of at least 4 narrowbodies and 4 widebody jet that have not been retired for more than common year.

As part of his briefing, he propos a conception to monitor the condition of aircraft wiring and electrical arrangements To this suggestion, one ATSRAC member pointed public that the Space Shuttle is monitored from beginning to end including its wiring, yet five next to the firsts after the Shuttle Columbia lifted on the farther side last July "a wire welded itself to a screw" That arcing chop off the power to brace of the Shuttle's three engines (a backup combination of parts to form a whole took over). "Monitoring for five years didn't catch this," the skeptic noted.
