Abstract:

OONR reported the T-39 organic brake, PN 9541626, wear life of 35-40 landings was unsatisfactory. OONER proposed an improved design tri-metallic brake, PN 9550338, for the T-39. To allow early evaluation, prototypes of the proposed brakes were utilized to obtain an estimation of service life improvement. The prototype brake, PN 5E5-124, lasted for 486 landings, before the wearout limit was obtained. Two production brakes PN 9550338 were then available. The production brakes were tested and 517 landings were obtained before removal for wear. Author
