The Federal Aviation Administration (FAA), continuing a stream of safety regulations flowing from the 1996 explosion aboard TWA Flight 800, is proposing fuel-tank wiring retrofits on 352 cargo jets operated in the U.S.
In an unusual standoff, Boeing insists the risk is negligible and is balking at the fix.
It says it won’t design the wiring modification the agency wants installed on in-service 757 cargo planes, instead offering only a more expensive solution.
In turn, industry trade group Airlines for America (A4A) cites the lack of a Boeing wiring design and the cost of the alternative fix as reasons to stall the proposed FAA rule.
The cargo-jet dispute reflects a serious disagreement over the scale of risk involved.
The FAA says the planes have an “unsafe condition” that “could result in fuel-tank explosions and consequent loss of the airplane.”
