This new rule should boost wiring safety by imposing new wiring-related maintenance and inspection tasks. The rule applies to all transport category airplanes with 30 or more seats or a maximum payload of 7,700 pounds for which type certificates (TCs) have been issued and to all applicants for pending Supplemental Type Certificates (STC). The rule requires manufacturers to develop Instructions for Continued Airworthiness (ICA) that will treat wiring as a separate system and will ensure the integrity of the wiring installed on the airplane (TCs) or modified in any way (STCs).

Various criticisms have been generated in recent weeks over unimportant and potentially misleading phraseology in accident reports produced by the National Transportation Safety Board (NTSB).
