Unsafe Condition

Missing clamps that are required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension can result in chafing of the AC feeder cable. A chafed and arcing AC feeder cable could puncture the adjacent hydraulic line, which, in combination with the use of the alternate extension system, could result in an in-flight fire.
