Automatic Dependent Surveillance-Broadcast (ADS-B) Out Performance Requirements To Support Air Traffic Control (ATC) Service; Technical Amendment; Correction
The FAA is correcting a final rule technical amendment published on February 9, 2015 (80 FR 6899). In that final rule, which became effective on the date of publication, the FAA corrected errors in regulatory provisions addressing Automatic Dependent Surveillance- Broadcast Out equipment and use. The FAA inadvertently listed an incorrect Amendment Number for that final rule. This document corrects that error.
Air Carrier Contract Maintenance Requirements
The Federal Aviation Administration (FAA) amends the maintenance regulations for domestic, flag, and supplemental operations, and for commuter and on-demand operations for aircraft type certificated with a passenger seating configuration of 10 seats or more (excluding any pilot seat). The new rules require affected air carriers and operators to develop policies, procedures, methods, and instructions for performing contract maintenance that are acceptable to the FAA, and to include them in their maintenance manuals. The rules also require the air carriers and operators to provide a list to the FAA of all persons with whom they contract their maintenance. These changes are needed because contract maintenance has increased to over 70 percent of all air carrier maintenance, and numerous investigations have shown deficiencies in maintenance performed by contract maintenance providers. These rules will help ensure consistency between contract and in-house air carrier maintenance and enhance the oversight capabilities of both the air carriers and the FAA.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211 Trent 875-17, 877-17, 884-17, 884B-17, 892- 17, 892B-17, and 895-17 turbofan engines. This AD requires modification of the engine by installing upgraded software in the electronic engine control (EEC) or by removing any EEC that incorporates a software standard prior to B7.2 and installing an EEC eligible for installation. This AD was prompted by failure of the intermediate pressure (IP) turbine disk drive arm and subsequent overspeed and burst of the IP turbine disk on an RR RB211 Trent turbofan engine. We are issuing this AD to prevent overspeed of the IP turbine disk, resulting in failure of the turbine blades or the IP turbine disk and subsequent uncontained release of the turbine disk and/or blades, which could lead to damage to the engine and damage to the airplane.
