FAA-DER Approvals of repairs/alterations. (Issue of FAA form of approval 8110-3)
Repair development support in Engine parts, APU parts, QEC externals and Acessories components.
Composite repairs in Nacelle, thrust reversers, flight control surfaces and structures.
Currently 60% of the engine overhaul cost is due to parts replacement (new and serviceable). Only 25% of the cost is associated with ?generic and advanced repairs? performed on engine components. By increasing the repair development activities on parts and replacing the limited quantity of new and used parts, an MRO facility can substantially reduce the engine overhaul cost and pass the savings to airlines. High spare parts price is driving the economy of parts repairs. Parts repair as means of cost reduction, especially on fleet hour arrangements or flat rate contracts is a common sense option that the airlines, MRO facilities should consider.
On older engine or aircraft programs, MRO facilities and airlines does not have the support of OEM for new repair development, therefore the options to the end user is SCRAP, a long lead, high cost component, or develop a FAA DER approved Repair!
On current engine programs the OEM has removed a standard repair from the ESM and made it ?Source Approved? only! This is to protect their proprietary technology.
On newer engines the OEM has not developed a repair for current problem or taking long time to come up with solutions. This is to sell new parts as long as they can and stall the repair development projects.
With 25 years plus experience of repair development activities on engine parts and aircraft components, and with current knowledge of new materials technology and processes, our engineers can help you develop timely cost saving repairs for your customers. With delegated authority from FAA on engines, Nacelles, APU components and structural composite assemblies for major repairs/alterations approval, our FAA-DER engineers can approve your repairs providing compliance to regulations with good substantiating data.
