Specific Pratt & Whitney jet engines must replace fire-prone sensors

The US aviation regulator proposes that certain Pratt & Whitney jet engines must replace their pressure burner sensors. This means airlines operating these engines will have to install new parts to prevent engine fires and in-flight shutdowns.

Airlines operating a specific fleet of older Pratt & Whitney engines will now have to spend money to replace a known faulty part. This will reduce the risk of engine fires and failures that have already occurred on these aircraft.
