single of the concerns raised at last week's ATSRAC meeting involved minutes from the previous gathering, in which it was asserted that "nuisance trips of healthy circuits are relatively attend much [i]or[/i] regularly and resetting is needed." ATSRAC member Jim Shaw, a B767 pilot representing the Air Line Pilots Association (ALPA), pointed disclosed that if the circuit is functioning normally, the circuit breaker should not trip. Above all, pilots should not be encouraged to reset circuit breakers, as was the case involving an electrical fire forward an L-1011 last November (see ASW, July 12) "Pilots are doing it, if it were not that they need guidance," Shaw declared. The committee therefore agreed to the following statement, which may attend as the germ for policy statements issued through carriers:

"Advisory Circular (AC) 25-16 states that resetting circuit breakers is discouraged for polyimide wire. It was pointed disclosed that AC 25-16 is a design guidance document applicable to design of aircraft and increase of crew procedures for flight and operations manuals. It is not an operational guidance document. Further, it was pointed abroad that it is not possible to identify to a gang which circuit breakers protect circuits with polyimide wire, in the same manner it is not possible to bring to maturity procedures to prevent reset.

"Mr Jim Shaw, the ALPA representative, while expressing affect about continued resetting of circuit breakers, also acknowledged that nuisance trips do come about ALPA feels that resetting of popp circuit breakers should be limited to those necessary for continued safe flight." >> Shaw, tel 402/894-5325 <<
