Part 43 and its Managerial Implications

Part 43 and It\'s Managerial Implications

When we talk about aviation maintenance, we speak of repairs, alterations and the act of preserving an aircraft in its original airworthy condition. An airworthiness certificate is given to an aircraft after countless hours of design, research and testing. And in order to keep this certificate valid; an aircraft must be maintained in accordance with a certain specification. These specifications are brought to us by the Federal Aviation Administration. The Federal Aviation Regulation part that spells out these rules is found in part 43. These acts are performed to prevent harm to pilots, passengers, and even innocent bystander that may become involved in an incident due to improper maintenance. As maintenance managers, we must understand these implications that must be followed, so that we may ensure that our facility is performing to the standards set upon us by the FAA.
The Federal Aviation Act of 1958 allowed for the regulation of air commerce in such manner as to best promote its development and safety (Adamski and Doyle 4-8). This brought about a rulemaking process to insure that all aspects of aviation could be regulated in a way as to provide maximum safety to all. This was the initial birth of 14 CFR 43, or Part 43 of the FAR\'s which is ironically titled Maintenance, Preventive Maintenance, Rebuilding, and Alteration (Federal Aviation Regulations [FAR], VII, 1997). This part has been primarily written for individuals or repair facilities that may be performing some sort of maintenance, preventive maintenance, rebuilding and or alterations. It refers to a number of qualified individuals that include holders of mechanic, repairman, air carrier, or even a pilot\'s certificate, that may perform an array of the procedures listed in this part. So when it comes down to it, we as maintenance managers must know and live by FAR prt. 43 in order for our employees to work and perform in a legal and safe manor.
As the title implies, this part of the Federal Aviation Regulations prescribes rules of governing the maintenance, preventive maintenance, rebuilding, and alteration of any aircraft having a U.S. airworthiness certificate; any foreign-registered aircraft used to carry mail under pt.121, 127 or 135; and airframe, aircraft engines, propellers, appliances, and components of such aircraft. This is exclusive of aircraft holding an experimental airworthiness certificate, unless the aircraft was previously issued a different kind of certificate (FAR, 1998, p.11). So if we were working as a manager in the U.S., this part would definitely apply to our facility, which repairs and maintains aircraft found in this category.
Part 43 also identifies persons that are authorized to perform and return an aircraft, airframe, aircraft engines, propellers, appliances, or component parts for return to service after maintenance, preventive maintenance, rebuilding, or alteration. "The approval for return to service will be made in accordance with FAR 43.9(a)(5). A&P mechanics are authorized to conduct and approve for return to service aircraft inspected in accordance with the owner or operator\'s program under a number of options. It can be done under performance rules for inspection to which determines whether an aircraft meets all requirements for airworthiness. Or by an inspection program under FAR 43 App. D. All work must be done in accordance with "airworthiness limitations" (King 38). This means that a manager must know who is performing the prescribed work in his shop, and make sure that any work completed is done in a specific, approved fashion.
A manager must know what types of inspections are being performed to aircraft in his/her shop. Individuals holding the appropriately rated certificate can only perform those inspections in which they are allowed to do. Managers must be fully aware of what part of the FAR\'s their shop is performing inspections under. Different parts of the regulation require adherence to specific rules found, but not specific to Part 43. If an aircraft comes in for an annual inspection, the manager must have an IA available to do the inspection, but if the inspection is a 100-hour, a certified mechanic is only needed in order to return the aircraft to service. A manager must realize that someone not certified cannot work under a certified mechanic when doing a 100-hour inspection. So the mechanics helper cannot perform the inspection during
