FAA proposes inspections for water leaks in Boeing 777F cargo planes

The Federal Aviation Administration is proposing a new rule that would require airlines operating Boeing 777 Freighter aircraft to inspect their potable and waste water systems for leaks. The proposal targets specific models of the large cargo freighter variant, where water from upper deck or main deck sources could potentially leak into an electrical equipment bay cooling air inlet.

Why it matters: This rule affects the safety of cargo operations by preventing water damage to critical flight electronics. Although only four such planes are registered in the U.S., the cost per inspection cycle is estimated at $425 in labor, with no parts cost required for the initial checks. The FAA notes that if leaks are found, additional repairs could take up to six hours of labor.

Who it affects

• Airlines operating Boeing 777 Freighter aircraft on U.S. registry
