From page 59...
... The development of several NDI systems is being done by small businesses; the Air Force will need new techniques or hybrid techniques to improve both the identification and quantification of the defect. Quantified values, which could then be fed back into models developed to predict remaining life, would play a vital role in determining maintenance or inspection intervals, both of which affect operation and support so

... to relieve stresses or to create residual stresses would increase fatigue life. Issues related to the role of these stresses and their interactions with the environment can influence the safety factors incorporated in designs for aircraft structures.

From page 61...
... The Air Force does not have cost ownership and usage models to help plan the retirement of aircraft, develop maintenance interval guidelines, and make early budget allocations in an austere environment. A number of the available cost models currently being successfully adapted by a number of Air Force groups for their analyses of cost of ownership and economic service life originated in SBIR programs, and the SBIR community could play an important role in developing or adapting these models for aging aircraft.

... modeling and understanding galvanic corrosion, stress-corrosion cracking, corrosion fatigue, and all the other insidious forms of corrosion and (2) developing tools for NDE/NDI and software to analyze data in these areas should be solicited from the small business community.
