The classes will cover all aspects of design, analysis, installation, quality control and in-service inspection. Finally, a set of training classes are being developed to safely integrate composite doubler technology into the commercial maintenance depots. The NDT procedure for bonded composite doublers (ultrasonic resonance technique) was also included in the Boeing NDT Standard Practices Manual. The engineering drawing for the composite repairs was integrated into the SRM. Using these look-up tables, maintenance facilities can have the option of choosing the traditional metallic repair or the ‘equivalent’ composite doubler repair. The SRM revisions-incorporating DC-10, MD-11, MD-80, MD-90 and 717 aircraft-take the form of a look-up table that allows users to match flaw type/size with either a metallic repair or the equivalent composite doubler repair. This allows for more routine use of composite doubler repairs within the allowable application regime specified in the manuals.
#Ata chapter for fueselage corrosion manuals
Dennis Roach, Kirk Rackow, in Aircraft Sustainment and Repair, 2018 8.3 Revision of Structural Repair ManualĪfter successful completion of the Pilot Program, the Structural Repair Manuals were modified to include this set of three composite doubler designs.
