2. Deviation Authority Something new, which will allow the Repair Station flexibility in maintenance operations that would be identified in the Repair Station's Operating Limitations. (FAA has requested specific comments from the public on this section of the NPRM.)
3. Ratings: FAA is looking at issuing Ratings and Classes based on certification standards. There will be nine ratings: Airframe, Powerplant, Propeller, Avionics, Computer Systems, Instrument, Accessory Rating, Limited Ratings and Specialized Service Rating.
Class: There are seven Airframe Class ratings:
Class 1: Aircraft other than rotorcraft and aircraft composed primarily of composite material that weigh less than 12,500 pounds maximum certificated take off weight.
Class 2: Aircraft other than rotorcraft and aircraft composed primarily of composite material that weigh more than 12,500 pounds maximum certificated take off weight and including 75,000 pounds maximum certificated take off weight.
Class 3: Aircraft by make and model, excluding rotorcraft and composite aircraft over 75,000 pounds maximum certificated take off weight.
Class 4: Rotorcraft of 6,000 pounds maximum certificated take off weight or less, excluding those rotorcraft composed primarily of composite material.
Class 5: Rotorcraft of 6,000 pounds maximum certificated take off weight or more, excluding those rotorcraft composed primarily of composite material.
Class 6: Aircraft composed primarily of composite material of 12,500 pounds maximum certificated take off weight or less.
Class 7: Aircraft composed primarily of composite material of 12,500 pounds maximum certificated take off weight or more.
Class 1: Reciprocating engines.
Class 2: Turbopropeller and Turboshaft engines
Class 3: Turbojet and Turbofan engines.
Class 1: Fixed-pitch and ground-adjustable propellers.
Class 2: Variable-pitch propellers.
Class 1: Communication equipment.
Class 2: Navigational equipment
Class 3: Pulsed equipment Computer
Class 1: Aircraft computer systems
Class 2: Powerplant computer system
Class 3: Avionics computer systems
Class 1: Mechanical
Class 2: Electrical
Class 3: Gyroscopic
Electronic. Accessory Rating:
Class 1: Mechanical accessories that depend on friction, hydraulic, mechanical linkage or pneumatic pressure for operation.
Class 2: Electrical accessories that depend on or produce electrical energy.
Class 3: Electronic accessories that depend on transistors, lasers, fiber optics, solid state integrated circuits, vacuum tubes or similar devices.
Class 4: Auxiliary Power Units: (APU) installed on aircraft as self-contained units.
These ratings will be issued for aircraft, airframes, powerplants, propellers, avionics, computer systems, instruments, and accessories by make and model.
Specialized Service Rating: These ratings will be issued for any specialized service the Administrator finds appropriate for this rating.
NOTE: If the NPRM is adopted, there will be a huge administrative burden to update ratings and classes both on the FAA district office and industry. The NPRM requests any ideas from the industry to make the transition a little bit easier.
5. Quality Assurance: One of the NPRM changes will be the requirement for a Quality Assurance system in which the Repair Station will monitor its workmanship. Smaller Repair Stations will be able to assign individuals to quality assurance on a part time basis.
6. Capability List: The capability list will identify all the articles by make and model on which the repair station is capable of performing work: The Repair Station's ratings and classes will still be identified on its Operating Specifications. However, the repair station can update its capability list based on a self-evaluation of its training, tools and equipment, data, etc. After that self-evaluation, add a particular make and model article to its capability list, and then be able to perform maintenance on that article without getting its Operating Specifications changed.
