Aircraft Certification | assuranceestheticienne.info
Aircraft modificationThe move now is for aircraft maintenance organisations who have traditionally carried out aircraft modification to STC to seek from the FAA what they term Organisation Designation Approval ODA. After approval, the company receives Supplemental Type Certificate (STC) Organization Designation Authorization (ODA). This designation enables a company to approve design data, tests, and analysis and allows the company to sign an STC on behalf of the Federal Aviation Administration (FAA) for aircraft alterations. In practice, it is a means of self-certifying their own work.As part of this ODA, a company uses a team of experienced engineers, pilots and other aero industry professionals to provide design and certification services. They can then issue STCs for alterations and modifications on a broad range of aerospace products. These include complete aircraft interiors, aero engine retrofits, airframe modifications, cabin in flight entertainment systems, glass cockpits and other major avionics upgrades.The benefit to the operator of the aircraft is that of saving downtime, because STC certification can now be delivered so much quicker, in from 45 to 60 days. The new ODA is not tied to an FAA Repair Station, and certification work can be done on aircraft in approved facilities anywhere around the world.EASA Part M CAMOThis is echoed by a similar approach in Europe where an EASA Part M continuing airworthiness management organisation CAMO can certify from general aviation through corporate aircraft maintenance to large aircraft and airline fleet requirements. An approved company under EASA Part M Subpart G Continuing Airworthiness Management Organisation (CAMO) gets its approval through their national aviation authority, in the UK, CAA. This approval permits an organisation to manage the continuing airworthiness of EASA aircraft ranging from GA through to large aircraft. This work can be carried out independently or through sub-contract support. The CAMO approval includes Airworthiness Review Certificate (ARC / Subpart I) privileges and the ability to indirectly approve aircraft maintenance programmes and amendments for customers on behalf of the UK CAA.Supplemental Type Certificates STCsSupplemental Type Certificates (STCs) are documents issued by the Federal Aviation Administration approving a product (aircraft, engine, or propeller) modification. The STC defines the product design change, states how the modification affects the existing type design, and lists serial number effectiveness. It also identifies the certification basis listing specific regulatory compliance for the design change. Information contained in the certification basis is helpful for those applicants proposing subsequent product modifications and evaluating certification basis compatibility with other STC modifications.The FAA denies its new Organisation Designation Approval ODA, could compromise safety standards, but claims the new self-certification process will transform how aircraft interior companies and even aircraft manufacturers like Cessna, Gulfstream and Boeing, go about the all-important business of making sure their products and processes are safe.Although the FAA set up the self-certification programme in 2006, ODA is not an easy thing to obtain. The successful applicant is acting as the FAAs agent, on behalf of the FAA, to issue type certificates and to certify everything from seats, galleys, lavatories and in flight entertainment systems to production, aircraft design and even airworthiness. Gulfstream was the first aircraft manufacturer to win ODA authority. It is seen as a logical step on from existing organisational delegation programmes, optimising those existing programmes. Sometimes, aircraft modification will require structural strengthening of the cabin floor. Engineering teams must design the new configuration and carry out stress and flammability testing of everything that will go on the aircraft, ensuring, for example, that the seats meet the latest 16g requirements and the lavatories meet 9g requirements. As the overall interiors integrator, a company with ODA brings in all the other suppliers, from the seat maker to the IFE provider.In the past, all the data involving the installation process of a new aircraft interior would have to be submitted in stages to the FAA for approval. The FAA has managed this process by using Designated Airworthiness Representatives DARs and Designated Engineering Representatives DERs. These inspectors. appointed by the FAA, may be employees of the company or outside contractors, but they represent the ears and eyes of the FAA Within that company. These representatives of the FAA have the authority to certify particular items and processes as safe on behalf of the agency. Former in-house inspectors are now part of an ODA organisation, and instead of the FAA signing off on the data, its all done in-house.Under the old FAA-managed system delays were common and estimates of when the interiors work might be accomplished or when the customer would be able to return an aircraft to service a stumbling block. An eight-week reduction in a modification project and a week to 10 days in issuing the STC is a significant saving. From an operator’s point of view, the contractor is also more accountable.Equally, for someone in the FAA to go out and inspect a Boeing brake system, for example, when Boeing could do it themselves is in many ways not logical. In practice, operating as a DOA, Boeing could have more FAA audits and more supervisory visits on a recurring basis than ever before.
Can Organic Degreasers Do a Good Enough Or Better Job Than Chemical Degreasers? | assuranceestheticienne.info
Through recent decades efforts to decrease the output of dangerous toxins into the atmosphere have made a dramatic improvement. At the same time consideration is also being given to contaminants ending up in the ground water and soil which ultimately affects both animal and plant life.There are significant advantages for industries to make the transition to the more eco friendly bio degreasers. Probably the most important consideration is the overall safety in using bio based solvents not only to the environment but also to the workers using them. Non organic cleaners and degreasers are typically composed of hazardous chemicals or are petroleum based solvents which are highly combustible.A significant advantage of organic degreasers is that they are designed to remove insoluble substances. Environmentally friendly substances do not contain ozone depleting chemicals. They are less harmful to humans as well as being non corrosive. In addition high performance characteristics can be achieved due to the lack of residue after cleaning.The current trend is for companies to utilize more eco friendly degreasers and cleaners. An industry leading in the use of degreasers and solvents is in aerospace. When you consider the level of cleanliness required, there are many mechanical parts, as well as electrical parts within the aerospace products which would benefit from not being exposed to such corrosive chemicals.On the surface level it would appear that the use of conventional commercial degreasers and solvents would be considerably less expensive than the environmentally friendly counterpart. The components are not that involved or engineered and don’t fall under the same regulations as bio based solvents. However, to balance out the equation, the disposal of organic cleaning substances is less involved and easier to handle and dispose.As for the effectiveness of organic degreasers vs. the conventional hazardous, may still be in the earlier stages of development and effectiveness. The processes involved in utilizing organic solvents may be specialized in their usage and applications which could greater add to the cost effectiveness. Whereas a chemical solvent’s uses may be more versatile in being able to accomplish multiple cleaning jobs with one solvent. The other side of the equation is the consideration in using biodegradable degreasers is that safe storage and temperature control are not significant factors. Not to mention no longer requiring the level of safety equipment in the application of the bio based substances or the issues involved with the disposal of waste from the chemicals.Considering the ongoing trend is to continue going green more development of even more effective green cleaners will follow. As the popularity, usage, and demands grow not only will improved organic products be developed and available, but also the pricing and overall usage should become more cost effective. Products currently exist that have been specially developed to breakthrough greasy grime and with time will only become even more effective. Who knows, the lubricants causing the grime are being developed as well to be eco friendly and better for the environment as they break down from cleaning. Regardless, going green and using biodegradable products creates a win-win situation for all involved.
