| Abstract Scope |
A helicopter had crashed due to a loss of cyclic control. It was determined that the hydraulic system lost pressure as determined by an eye-witness account and analysis of the light bulb filaments in the master caution indicator panel. The source of the hydraulic pressure loss was located along with evidence that suggested improper maintenance while the aircraft was operated under a time-constrained contract. |
