Investigation Team: Lisa Brasche, Rick Lopez, Brian Larson, David Eisenmann - Iowa State University

Industry Partners: Boeing, Rolls Royce, Pratt & Whitney, General Electric, United Airlines , Delta Airlines, D&W, Sherwin

Objectives:

  • To identify factors for where engineering data is insufficient, assess parameter ranges that provide acceptable performance for typical aircraft and engine components, and document results for use in revision of industry specifications
  • To develop a self–assessment tool and protocol for use by airline and overhaul shops for performance verification compared against industry–accepted performance

  • To complete assessment of process control and monitoring tools and provide needed improvements

  • To develop/validate FPI guidance materials

Approach:

  • Define factors for which engineering data is deficient

  • Design engineering study that provides quantitative assessment of performance and complete study using either lab or shop facilities as appropriate
  • Transition process to airlines for internal, self-assessments

  • Distribute results through use of web and support changes to industry specifications as warranted

  • Utilize results to update/create guidance materials

In cooperation with the FAA-NDE-NRS, CASR staff have worked with industry to define a comprehensive program to provide engineering data, performance verification tools, and guidance materials in response to industry definition.

Products:

  • Engineering data and FPI resource website
    for publication of data

  • Guidance materials for use by industry
    and FAA

  • Development of a self assessment tool
    and protocol
